MiCA & EU Crypto Regulation Glossary

Advice on Crypto-Assets MiCA Defined Terms

Per MiCA Article 3(1)(24), advice on crypto-assets is offering, giving, or agreeing to give personalised recommendations to a client, either at the client's request or on the CASP's own initiative, about transactions in crypto-assets. Generic market commentary is not advice; personalised recommendations are.

MiCA Article 3(1)(24) ↗

Airdrop White Paper & Token Issuance

An airdrop is the distribution of tokens to specified addresses or users at no direct cost. Exempt from MiCA white-paper requirements under Article 4(2)(b) where genuinely free and without conditions producing consideration. Conditional airdrops (e.g., requiring social-media follow) may not qualify.

MiCA Article 4(2)(b) ↗

Algorithmic Stablecoin Stablecoins (ART / EMT)

An algorithmic stablecoin maintains its peg through algorithmic supply expansion and contraction rather than asset reserves. Recital 41 says such tokens are still ARTs or EMTs if they aim to keep a stable value by referencing a currency or other assets, so Titles III and IV apply in full, reserves included; algorithmic tokens that reference no asset fall under Title II. The collapse of Terra/UST in 2022 informed that approach.

Anti-Money Laundering (AML) AML & Travel Rule

AML is the body of law preventing money laundering. EU framework: AMLR (2024/1624) directly applicable from July 2027; AMLD6 (2024/1640) at national infrastructure level; 5AMLD (2018/843) transitional. CASPs are obliged entities required to apply customer due diligence, monitoring, and reporting.

Regulation (EU) 2024/1624 ↗

Article 60 Notification Process & Authorisation

MiCA Article 60 establishes a 40-working-day notification route for entities already authorised under their respective sectoral regimes (CRR, EMD2, MiFID II, UCITS, AIFMD) to provide crypto-asset services. Notification, not authorisation — substantive MiCA conduct rules still apply.

MiCA Article 60 ↗

Asset Reserve Stablecoins (ART / EMT)

The ART reserve under MiCA Article 36 is the pool of liquid, high-quality assets that backs outstanding ARTs at all times. It must be legally and operationally segregated from the issuer (Article 36(2)-(3)), held by a custodian under Article 37 and invested only in highly liquid instruments under Article 38; liquidity detail is set by EBA RTS under Article 36(4). Reserve assets must at least cover the tokens in circulation.

MiCA Articles 36-38 ↗

Asset-Referenced Token (ART) MiCA Defined Terms

An ART is a type of crypto-asset that purports to maintain a stable value by referring to any other value or right, or a combination thereof, including one or more official currencies. Single-currency-pegged stablecoins are EMTs, not ARTs. Issuers of ARTs need authorisation under MiCA Title III.

MiCA Article 3(1)(6) ↗

Authorisation Withdrawal Process & Authorisation

Under MiCA Article 64(1), the home NCA must withdraw CASP authorisation where the CASP has not used it within 12 months, renounced it, provided no services for nine consecutive months, obtained it by irregular means, no longer meets the conditions and has not remedied this in time, lacks effective AML/CFT systems, or has seriously infringed AML/CFT rules; Article 64(2) adds optional grounds. A CASP providing custody, a trading platform, exchange, order execution or placing must have a plan for an orderly wind-down (Article 74).

MiCA Article 64 ↗

Automated Market Maker (AMM) DeFi & Crypto Technical

An AMM is a DeFi protocol where prices are determined by a mathematical formula applied to liquidity-pool reserves, rather than by an order book. Major examples: Uniswap (constant product), Curve (stable-swap), Balancer (multi-asset). Liquidity providers earn trading fees.

Autorité de Contrôle Prudentiel et de Résolution (France) (ACPR) EU Regulators & Authorities

The ACPR is the French prudential supervisor for banks, insurance, and investment firms. For French CASPs, the ACPR handles prudential supervision (own funds, governance, ICT resilience) while the AMF handles conduct supervision. The two-headed model is similar to Italy's CONSOB/Banca d'Italia split.

Autorité des Marchés Financiers (France) (AMF) EU Regulators & Authorities

The AMF is the French markets regulator and the designated MiCA NCA for conduct supervision. It runs one of the EU's most sophisticated supervisory regimes, with a strong PSAN history pre-MiCA. ACPR handles the prudential side; the AMF handles conduct, consumer protection, market integrity.

Autoriteit Financiële Markten (Netherlands) (AFM) EU Regulators & Authorities

The AFM is the Dutch markets-conduct supervisor and the MiCA NCA for the Netherlands. It handles CASP licence applications and supervises CASPs' compliance with the Wwft (AML) and the Sanctions Act; DNB covers prudential matters such as own funds and qualifying holdings.

Read more: Netherlands — crypto licensing

Banca d'Italia EU Regulators & Authorities

Banca d'Italia is the Italian central bank and the prudential supervisor for CASPs under Italy's split-supervisor MiCA model. Handles own-funds calculation, governance arrangements, ICT risk management, and AML supervision. Works with CONSOB on coordinated case files.

Bank of Lithuania (BoL) EU Regulators & Authorities

The Bank of Lithuania is the Lithuanian central bank and the designated MiCA NCA. It runs the highest-throughput CASP authorisation pipeline in the EU — 3-5 months for Class 1/2 files, 5-7 months for Class 3. AML supervision is split with the FCIS.

Read more: Lithuania — crypto licensing

Bankruptcy-Remoteness Custody & Safeguarding

Bankruptcy-remoteness places client crypto-assets outside the CASP's insolvency estate under home-state insolvency law. How it is achieved depends on national law: statutory segregation, trust or fiduciary arrangements, or a separate custody entity. Required by MiCA Article 75(7) for custody assets and Article 70(1) for any CASP holding client assets.

MiCA Article 75 ↗

Beneficial Ownership (BO) AML & Travel Rule

Beneficial ownership identifies the natural person(s) who ultimately own or control a customer that is a legal entity. The threshold is 25% direct or indirect ownership of capital or voting rights, or control by other means. AMLR requires verification against the national beneficial-ownership register.

Blockchain DeFi & Crypto Technical

A blockchain is a specific type of DLT organising transactions in cryptographically-linked blocks, with each block referencing the prior block. Public blockchains (Bitcoin, Ethereum) are permissionless; private blockchains (Hyperledger Fabric) are permissioned. MiCA is technology-neutral but most crypto-assets use blockchain DLT.

Branch Establishment Cross-Border & Passport

Branch establishment is the creation of a physical operational presence in a host EU member state — local office, dedicated host-state staff, host-state senior management. Requires a separate notification including operational details, beyond the basic passport notification.

MiCA Article 65 ↗

Bridge (Cross-Chain) DeFi & Crypto Technical

A cross-chain bridge transfers crypto-assets between different blockchains by locking the asset on the source chain and minting a wrapped representation on the destination chain. Operated by an identifiable legal entity (even with smart-contract automation) — typically falls within MiCA CASP scope for transfer services.

Canadian Securities Administrators (CSA) Non-EU Regulators

The CSA is the umbrella organisation of Canada's 13 provincial and territorial securities regulators. Canadian crypto-asset platforms register as MSBs federally with FINTRAC and as restricted dealers / crypto-asset trading platforms with provincial regulators (most importantly the OSC in Ontario).

Capital Requirements Regulation (CRR) Stablecoins (ART / EMT)

The CRR (Regulation (EU) No 575/2013) establishes prudential rules for credit institutions and investment firms in the EU. MiCA Articles 35 and 67 reference the CRR's CET1 definition for the quality of own funds. Credit institutions can issue ARTs via the Article 17 route and EMTs under Article 48.

Regulation (EU) No 575/2013

CASP Authorisation Process & Authorisation

CASP authorisation is the formal regulatory permission to provide crypto-asset services in the EU. Granted by the home NCA under MiCA Article 63 within a statutory clock of 40 working days from complete file. Authorisation specifies the authorised service set; expanding scope requires variation.

MiCA Article 63 ↗

Central Bank of Ireland (CBI) EU Regulators & Authorities

The CBI is the Irish central bank and the designated MiCA NCA. English-only filing, 12.5% corporate tax, and the strongest institutional reputational signal among EU jurisdictions. Heaviest substance requirements; longest substantive review timelines.

Read more: Ireland — crypto licensing

Circulating Supply White Paper & Token Issuance

Circulating supply is the number of tokens publicly available for trading at a given moment. Excludes tokens held in vesting contracts, reserves, or burn addresses. Important market-data point for valuation; used to calculate market cap.

Close Links MiCA Defined Terms

Close links exist where two persons are linked by participation (20%+ ownership), control, or a permanent contractual relationship. The concept is used in MiCA to identify situations that could impair effective supervision.

MiCA Article 3(1)(31) ↗

Cold Storage Custody & Safeguarding

Cold storage holds private keys offline — air-gapped, hardware-secured, geographically distributed. Protects against network-based attacks. MiCA sets no cold-storage percentage; Article 75(3) requires a custody policy that minimises the risk of loss from fraud, cyber threats or negligence, and the hot/cold split is the CASP's documented risk decision.

MiCA Article 75(3)

Comisión Nacional del Mercado de Valores (Spain) (CNMV) EU Regulators & Authorities

The CNMV is the Spanish securities markets regulator and the designated MiCA CASP supervisor. AML supervision is split with SEPBLAC. The CNMV applies investment-firm-style governance expectations to CASP files; the supervisory dialogue is rigorous but accessible.

MiCA Article 93 ↗

Consensus Mechanism DeFi & Crypto Technical

A consensus mechanism is the protocol that nodes follow to agree on which transactions are valid and added to the blockchain. Main types: Proof of Work (Bitcoin), Proof of Stake (Ethereum post-Merge, Solana, Cardano), and variants (DPoS, Tendermint BFT, etc.).

Control MiCA Defined Terms

Control under MiCA references the Directive 2013/34/EU definition: holding a majority of voting rights, the right to appoint/remove a majority of management body members, or the right to exercise dominant influence over the undertaking. Used in qualifying-holdings and close-links analysis.

MiCA Article 3(1)(31) ↗

Correspondent Relationship AML & Travel Rule

A correspondent relationship between CASPs (or between a CASP and a non-EU institution) is analogous to correspondent banking. Triggers EDD requirements: due diligence on the counterparty institution's AML controls, ongoing monitoring, restrictions on sub-correspondent relationships.

Counter-Financing of Terrorism (CFT) AML & Travel Rule

CFT is the parallel legal framework to AML, focused on disrupting financial flows that support terrorism. Treated jointly with AML under EU and FATF frameworks. Obliged entities apply integrated AML/CFT programmes covering both money laundering and terrorism-financing typologies.

Credit Institution Stablecoins (ART / EMT)

A credit institution is an undertaking authorised to take deposits and grant credit under the CRR. Credit institutions have streamlined routes into crypto-asset business: Article 17 for ART issuance (white-paper approval plus notification), Article 48 for EMT issuance (notification), and Article 60 for CASP services (notification).

CRR Article 4(1)(1)

Cross-Border Services Cross-Border & Passport

Cross-border services are crypto-asset services provided into a host state remotely, without establishing a physical branch or subsidiary. The standard MiCA passport mechanism covers cross-border services. Establishing a branch or subsidiary triggers additional notification and supervisory engagement.

Crypto-asset MiCA Defined Terms

Under MiCA Article 3(1)(5), a crypto-asset is a digital representation of a value or a right that can be transferred and stored electronically, using distributed ledger technology or similar technology. The definition is technology-neutral and captures fungible and non-fungible tokens — though NFTs may be exempt under Article 2(3).

Crypto-Asset White Paper MiCA Defined Terms

A crypto-asset white paper is the disclosure document required under MiCA Articles 6, 19, and 51 (depending on token type) before a public offer or admission to trading. Content follows Annexes I-III of MiCA and, since 23 December 2025, the iXBRL format in Commission Implementing Regulation (EU) 2024/2984. A Title II white paper is notified at least 20 working days before publication (Article 8(5)); an EMT white paper likewise (Article 51(11)); an ART white paper needs NCA approval.

MiCA Article 6 (Title II); Article 19 (Title III) ↗

Crypto-Backed Stablecoin Stablecoins (ART / EMT)

A crypto-backed stablecoin maintains stable value through over-collateralisation with other crypto-assets, as DAI does. Under MiCA the backing does not decide the category: a token that purports to keep a stable value by referencing one official currency is an EMT, and one referencing other values or rights, including crypto-assets, is an ART (Article 3(1)(6)-(7); Recital 41).

Custody and Administration of Crypto-Assets MiCA Defined Terms

Under MiCA Article 3(1)(17), this is the safekeeping or controlling, on behalf of clients, of crypto-assets or of the means of access to such crypto-assets, where applicable in the form of private cryptographic keys. Subject to Article 75 safeguarding rules.

Customer Due Diligence (CDD) AML & Travel Rule

CDD is the AML obligation under AMLR/5AMLD requiring obliged entities to identify and verify customer identity, understand the nature of the business relationship, and conduct ongoing monitoring. Three levels: standard CDD, simplified CDD (SDD), enhanced CDD (EDD).

Cyprus Securities and Exchange Commission (CySEC) EU Regulators & Authorities

CySEC is the Cypriot securities supervisor and the designated MiCA NCA for Cyprus. It runs one of the more accessible CASP authorisation pipelines in the EU — 4-6 months for clean files, EUR 50-150k capital, lighter substance than Estonia or Ireland but real.

Read more: Cyprus — crypto licensing

De Nederlandsche Bank (DNB) EU Regulators & Authorities

DNB is the Dutch central bank. Pre-MiCA, DNB ran the Netherlands' crypto-asset register from 2020. Under MiCA, the AFM authorises CASPs and supervises their AML and sanctions compliance; DNB handles prudential matters such as own funds and qualifying holdings.

Decentralised Autonomous Organisation (DAO) DeFi & Crypto Technical

A DAO is an organisation governed by on-chain voting, typically through a governance token. Often operates with an off-chain legal-entity wrapper (Cayman Foundation, Wyoming DAO LLC, Liechtenstein Trust). MiCA does not exempt DAOs from the CASP perimeter where they provide crypto-asset services.

Decentralised Finance (DeFi) DeFi & Crypto Technical

DeFi covers crypto-asset financial services operating on smart-contract protocols rather than through traditional intermediaries. Under Recital 22, crypto-asset services provided in a fully decentralised manner without any intermediary fall outside MiCA; where part of the activity is performed by an identifiable person, that person can need CASP authorisation. Article 142 asked the Commission to report on DeFi.

Regulation (EU) 2022/2554 ↗

Distributed Ledger Technology (DLT) MiCA Defined Terms

DLT means a technology that enables the operation and use of distributed ledgers. Distributed ledgers are information repositories that record transactions and are shared across, and synchronised between, a set of DLT network nodes. The most common DLT is blockchain.

MiCA Article 3(1)(1); Regulation (EU) 2022/858 ↗

E-money Token (EMT) MiCA Defined Terms

An EMT is a crypto-asset that purports to maintain a stable value by referring to the value of a single official currency. EMTs are regulated under MiCA Title IV via the EMD2 framework — issuers must be credit institutions or electronic money institutions (EMIs). Holders have a permanent right of at-par redemption.

Read more: MiCA Stablecoin Regulation Summary 2026 — Title III ART + Title IV EMT

MiCA Article 3(1)(7) ↗

EBA Guidelines Process & Authorisation

EBA Guidelines parallel ESMA Guidelines in EBA areas. Crypto examples: the Travel Rule Guidelines (EBA/GL/2024/11) and guidelines for ART and EMT issuers on recovery plans, redemption plans and liquidity stress testing. Same "comply or explain" mechanism; an explanation must be substantive, not formulaic.

EBA Significance Criteria Stablecoins (ART / EMT)

Article 43(1) lists seven criteria, used for both ARTs and EMTs (Article 56): more than 10 million holders; more than EUR 5 billion issued, in market capitalisation or in reserve; more than 2.5 million transactions and EUR 500 million a day; a DMA gatekeeper issuer; international significance; interconnectedness with the financial system; and an issuer of several tokens that also provides a crypto-asset service. At least three must be met.

MiCA Articles 43 (ART) and 56 (EMT) ↗

Electronic Money Stablecoins (ART / EMT)

E-money is electronically stored monetary value, including magnetically stored, representing a claim on the issuer, issued on receipt of funds for the purpose of payment transactions. Under EMD2 (Directive 2009/110/EC). MiCA Title IV applies the e-money framework to EMTs.

EMD2 (Directive 2009/110/EC) ↗

Electronic Money Institution (EMI) Stablecoins (ART / EMT)

An EMI is an institution authorised under EMD2 (Directive 2009/110/EC) to issue electronic money but not to take deposits. EMIs can issue EMTs under MiCA Article 48 by notifying the NCA and the white paper, using their existing EMD2 authorisation. ESMA's interim register lists EMT-issuing EMIs in France, the Netherlands, Luxembourg, Lithuania, Malta and other member states.

EMD2; MiCA Article 48 ↗

Emission Schedule White Paper & Token Issuance

The emission schedule specifies how new tokens are created over time. Examples: Bitcoin's halving every 4 years (decreasing supply curve); Ethereum's variable issuance based on staking participation; capped tokens with no further emission. Disclosed in MiCA white papers.

Enhanced Due Diligence (EDD) AML & Travel Rule

EDD is the strengthened CDD applied to high-risk customer categories: politically exposed persons (PEPs), customers from high-risk third countries, anonymous or pseudonymous transactions above thresholds, complex beneficial-ownership structures. Triggers more rigorous verification and ongoing monitoring.

Equivalence Determination Cross-Border & Passport

An equivalence determination is a Commission decision that a third-country regulatory framework provides equivalent protection to MiCA. Enables specific cross-border supervisory cooperation arrangements. As of 2026 no general MiCA equivalence has been issued; bilateral supervisory MoUs cover specific matters.

ESMA Guidelines Process & Authorisation

ESMA Guidelines are non-binding instruments under Article 16 of the ESMA Regulation. NCAs must say whether they comply or explain why they don't. MiCA examples: Guidelines on the conditions and criteria for the qualification of crypto-assets as financial instruments (ESMA75-453128700-1323); Guidelines on supervisory practices to prevent and detect market abuse under MiCA.

ESMA Regulation Article 16

ESMA Register Process & Authorisation

ESMA maintains the EU-wide public register of authorised CASPs, notified ART and EMT issuers, and significant-entity designations. Searchable, machine-readable. The single authoritative source for verifying CASP authorisation status across the EU.

Estonian Financial Supervision Authority (EFSA) EU Regulators & Authorities

The EFSA is the Estonian financial supervisor and the MiCA NCA. Professional, accessible supervisor in a low-cost EU jurisdiction. Six-month typical timeline for clean CASP files; English working dialogue accepted for supervisory engagement (formal filing in Estonian).

Read more: Estonia — crypto licensing

EU Passport Cross-Border & Passport

The EU passport under MiCA Article 65 is the right of an authorised CASP to provide services in any other EU member state after a notification: the home NCA forwards it within 10 working days, and the CASP may start on receiving confirmation or at the latest on the 15th calendar day after submitting it. One authorisation, twenty-seven member states. Host NCAs cannot block on substantive grounds; can engage on AML and consumer-protection issues.

MiCA Article 65 ↗

European Banking Authority (EBA) EU Regulators & Authorities

The EBA is the EU agency for banking supervisory convergence. Under MiCA, the EBA produces RTS on ART reserves, capital, and white-paper content, supervises issuers of significant asset-referenced and e-money tokens (Article 117), and establishes and chairs a college for each such issuer (Article 119).

Read more: MiCA Stablecoin Regulation Summary 2026 — Title III ART + Title IV EMT

European Central Bank (ECB) EU Regulators & Authorities

The ECB supervises significant credit institutions in the euro area under the SSM. Where a credit institution issues EMTs or ARTs under MiCA Article 17, the ECB engages on the prudential side. The ECB also plays a role in the DLT Pilot Regime for central-bank money settlement.

European Insurance and Occupational Pensions Authority (EIOPA) EU Regulators & Authorities

EIOPA is the EU agency for insurance supervisory convergence. Its MiCA role is narrower than ESMA or EBA — primarily around insurance policies that can substitute for CASP own funds under Article 67(5), and on the insurance-sector boundaries with crypto-asset activity.

European Securities and Markets Authority (ESMA) EU Regulators & Authorities

ESMA is the EU agency responsible for supervisory convergence in securities markets. Under MiCA, ESMA drafts technical standards and guidelines, keeps the EU-wide register of white papers, token issuers and CASPs (Article 109) and of non-compliant entities (Article 110), and receives notifications of significant CASPs and annual supervisory updates on them from national authorities (Article 85). It does not supervise CASPs directly.

Exchange of Crypto-Assets for Funds MiCA Defined Terms

Under MiCA Article 3(1)(20), this service involves the conclusion of purchase or sale contracts concerning crypto-assets against fiat currency, by using own capital. A core Class 2 CASP service, also known as on/off-ramping.

MiCA Article 3(1)(20) ↗

Exchange of Crypto-Assets for Other Crypto-Assets MiCA Defined Terms

Under MiCA Article 3(1)(21), this is the conclusion of purchase or sale contracts concerning crypto-assets for other crypto-assets, by using own capital. A core Class 2 CASP service that typically operates alongside fiat exchange services.

Federal Financial Supervisory Authority (Germany) (BaFin) EU Regulators & Authorities

BaFin is the German federal financial supervisor — supervises banks, insurance, securities, and now MiCA CASPs. The single-supervisor model produces administrative simplicity but the bar is uniformly high. Heaviest substance requirements in the EU; longest typical timelines.

Read more: Germany — crypto licensing

Fiat-Backed Stablecoin Stablecoins (ART / EMT)

A fiat-backed stablecoin maintains stable value by holding fiat currency reserves. Under MiCA, single-currency fiat-backed stablecoins are EMTs (Title IV); multi-currency or basket-backed are ARTs (Title III). Examples: USDC (USD-backed), Société Générale EUR CoinVertible.

Fifth Anti-Money Laundering Directive (5AMLD) AML & Travel Rule

5AMLD extended AML obligations to virtual currency exchange and custodian wallet providers from January 2020. Each member state transposed differently, producing the patchwork that AMLR (2027) replaces. Pre-MiCA crypto-asset registers in most EU member states were 5AMLD-based.

Directive (EU) 2018/843

Financial Action Task Force (FATF) AML & Travel Rule

The FATF is the inter-governmental body that sets the global standards on AML and CFT. Its 40 Recommendations are followed by 200+ jurisdictions. Recommendation 15 covers virtual-asset service providers; Recommendation 16 (the Travel Rule) requires data accompanying virtual-asset transfers.

Financial Conduct Authority (UK) (FCA) Non-EU Regulators

The FCA is the UK conduct supervisor for financial services. UK crypto-asset firms register under the Money Laundering Regulations 2017. The UK's post-Brexit framework is broadly parallel to MiCA but separate; no automatic EU passport between the UK and EU.

Read more: United Kingdom — crypto licensing

Financial Crimes Enforcement Network (US) (FinCEN) Non-EU Regulators

FinCEN is the US Treasury bureau enforcing the Bank Secrecy Act. Crypto exchanges operating in the US must register as Money Services Businesses (MSBs) — federal-level registration. State-level money-transmitter licensing applies in parallel.

Read more: United States — crypto licensing

Financial Intelligence Unit (FIU) AML & Travel Rule

Each jurisdiction has an FIU receiving STRs/SARs and conducting AML intelligence analysis. EU FIUs: UIF (Italy), CTIF-CFI (Belgium), TRACFIN (France), Hungarian FIU (Hungary), Cellule de Renseignement Financier (Luxembourg), etc. FIUs cooperate via the Egmont Group internationally.

Financial Market Authority (Austria) (FMA) EU Regulators & Authorities

The FMA is the Austrian financial markets supervisor. Applies banking-grade standards to MiCA CASP authorisation. Strong DACH-region positioning at materially lower setup cost than Germany; single-supervisor model produces administrative simplicity.

Read more: Austria — crypto licensing

Financial Services and Markets Authority (Belgium) (FSMA) EU Regulators & Authorities

The FSMA is the Belgian conduct supervisor and the designated MiCA NCA. NBB handles credit-institution-CASP supervision under Article 60 and AML. Small but engaged supervisor; strategic for platforms valuing EU institutional proximity (Brussels-based).

Financial Services Commission (Korea) (FSC) Non-EU Regulators

The FSC supervises South Korea's financial markets and crypto-asset business under the Virtual Asset User Protection Act (operational July 2024). Strict consumer-protection focus and reserve requirements for crypto-asset exchanges.

Fit and Proper Assessment Process & Authorisation

Fit and proper assessment is the NCA's evaluation of senior managers and qualifying shareholders during CASP authorisation. Covers professional knowledge, experience, reputation, financial soundness, criminal record, and time commitment. Failure to meet standards is a refusal ground.

Read more: CASP Operations and Lifecycle 2026 — MiCA Passport, Banking, Wind-Down

MiCA Article 68 ↗

Front-Running Market Abuse (MiCA Title VI)

Front-running is the practice of trading on knowledge of a pending client order before executing the client order itself — capturing the price-impact benefit for the CASP. Conduct breach under MiCA Articles 66-73 and a category of market manipulation under Article 91.

Fully Diluted Valuation (FDV) White Paper & Token Issuance

FDV is the token valuation calculated using the maximum total supply rather than current circulating supply. Reflects the theoretical market cap if all tokens were released. Often substantially higher than market cap; significant for investors evaluating long-term value dilution.

Governance Token DeFi & Crypto Technical

A governance token grants holders voting rights over a DeFi protocol's operational decisions — fee structure, treasury management, protocol upgrades. Examples: UNI (Uniswap), AAVE, MKR (MakerDAO). Under MiCA, governance tokens often fall within Title II scope as crypto-assets.

Group MiCA Defined Terms

A group under MiCA includes a parent undertaking and all its subsidiary undertakings. Group structure matters chiefly for issuers of asset-referenced and e-money tokens and for the assessment of qualifying holdings. Intra-group transactions are subject to specific transparency requirements.

MiCA Article 3(1)(31) ↗

Hardware Security Module (HSM) Custody & Safeguarding

An HSM is a physical computing device that safeguards and manages cryptographic keys, performing encryption/decryption inside its tamper-resistant boundary. CASPs use HSMs to protect master keys, signing keys, and other sensitive cryptographic material.

High-Risk Third Country AML & Travel Rule

High-risk third countries are non-EU jurisdictions identified by the European Commission as having strategic AML/CFT deficiencies. List published as a delegated act; updated periodically. Transactions involving these jurisdictions trigger EDD obligations for CASPs.

AMLR; Commission Delegated Regulation

Home Competent Authority MiCA Defined Terms

The home competent authority is the NCA in the member state where a CASP or crypto-asset issuer is established. It grants authorisation, supervises ongoing compliance, and processes passport notifications for cross-border service. The home NCA is the primary supervisory counterparty for the regulated entity.

MiCA Article 3(1)(31) ↗

Home State Cross-Border & Passport

The home state is the EU member state where a CASP has its registered office and head office, and where it holds MiCA authorisation. The home NCA is the primary supervisor for authorisation, conduct, prudential, and AML matters.

Hong Kong Monetary Authority (HKMA) Non-EU Regulators

The HKMA is Hong Kong's central bank-equivalent. Co-regulates stablecoin issuers alongside the SFC under the Stablecoin Ordinance (operational 2025). Supervises authorised banks providing crypto-asset services.

Host Competent Authority MiCA Defined Terms

The host competent authority is the NCA in a member state where a CASP operates via the MiCA passport but does not have its registered office. The host NCA receives the passport notification, may engage on AML and consumer-protection matters, but cannot block the passport on substantive grounds.

MiCA Article 3(1)(32) ↗

Host State Cross-Border & Passport

A host state is an EU member state in which a CASP provides services via the MiCA passport but does not have its registered office. Host-state NCAs engage on AML supervision, consumer-protection matters, and host-state-specific consumer-law overlays.

Hot Wallet Custody & Safeguarding

A hot wallet has its private keys on internet-connected infrastructure, enabling fast trading and withdrawals. Exposed to network attacks. MiCA sets no hot-wallet cap; the CASP sets limits in its Article 75(3) custody policy.

Implementing Technical Standards (ITS) Process & Authorisation

ITS are EU implementing acts that specify the uniform conditions of application for MiCA rules — typically forms, templates, reporting procedures. Drafted by ESMA/EBA, adopted by the Commission. Examples: ITS on CASP application forms, ITS on supervisory reporting templates.

Individual Segregation Custody & Safeguarding

Individual segregation maintains a unique wallet per client for that client's crypto-assets. More expensive operationally (per-wallet gas costs, key management) but easier to demonstrate to supervisors. Common for institutional clients and high-value retail.

Initial Coin Offering (ICO) White Paper & Token Issuance

An ICO is the typical structure for raising funds through a token sale, where the issuer sells tokens directly to investors. Predominant in 2017-2018 fundraising cycle; since regulated under MiCA Title II/III/IV depending on token classification.

Initial Exchange Offering (IEO) White Paper & Token Issuance

An IEO is a token sale conducted through a centralised exchange. The exchange handles distribution, KYC, and the technical sale infrastructure on behalf of the issuer. Under MiCA, the exchange is providing the "placing of crypto-assets" service; the issuer remains the substantive offeror.

Insider Dealing Market Abuse (MiCA Title VI)

Insider dealing is using inside information to buy, sell, cancel, or amend orders in crypto-assets. Prohibited under MiCA Article 89. Inside information is specific information about a crypto-asset or issuer that has not been made public and that would significantly affect the price.

MiCA Article 89 ↗

Interim Suspension Stablecoins (ART / EMT)

Under MiCA, NCAs can temporarily suspend ART or EMT issuance, marketing, or redemption where there is reasonable suspicion of breach. Interim suspension is a precautionary supervisory tool; it does not require formal authorisation withdrawal.

MiCA Article 105 ↗

Issuer MiCA Defined Terms

Under MiCA Article 3(1)(10), an issuer is a natural or legal person who issues crypto-assets. The issuer bears the obligation to prepare and publish the white paper, comply with marketing rules, and (for ARTs/EMTs) maintain ongoing authorisation requirements.

MiCA Article 3(1)(10) ↗

Japan Financial Services Agency (JFSA) Non-EU Regulators

The JFSA is Japan's integrated financial regulator. Japan was an early-mover on crypto-asset regulation via the 2017 Payment Services Act amendments. Strict licensing for crypto-asset exchange service providers; rigorous AML and customer-asset segregation requirements.

Know Your Customer (KYC) AML & Travel Rule

KYC is the identity-verification process that obliged entities apply to customers. Components: identification (collect data), verification (cross-check against documents), risk assessment, ongoing monitoring. CASPs apply KYC at onboarding and re-apply periodically.

Layer 1 (L1) DeFi & Crypto Technical

A Layer 1 blockchain is the base protocol where transactions are settled and consensus is reached. Examples: Bitcoin, Ethereum, Solana, Avalanche, Cosmos. Layer 1 design constraints (throughput, latency, cost) drive much of the crypto-asset technical architecture.

Layer 2 (L2) DeFi & Crypto Technical

Layer 2 protocols (Optimism, Arbitrum, Polygon, zkSync) operate on top of a Layer 1 blockchain to provide higher transaction throughput and lower costs while inheriting L1 security. Distinct from sidechains (separate consensus). MiCA generally treats L2-issued tokens the same as L1-issued tokens.

Liquidity Management (Stablecoin) Stablecoins (ART / EMT)

Liquidity management for stablecoin issuers covers reserve composition and maturities (Article 36 and the EBA RTS under Article 36(4)), the redemption policy (Articles 39 and 49), recovery-plan tools such as redemption limits (Article 46) and, for significant issuers, a liquidity management policy and liquidity stress tests (Article 45(3)-(4)).

Liquidity Pool DeFi & Crypto Technical

A liquidity pool is a smart contract holding deposited crypto-assets that enable AMM-based trading. Liquidity providers (LPs) deposit assets in exchange for LP tokens representing their share; earn trading fees in proportion to their share. Subject to impermanent-loss risk.

Lock-Up Period White Paper & Token Issuance

A lock-up period restricts the transfer or sale of tokens for a specified period after distribution. Used to prevent immediate sell-pressure from early investors. Typical for team allocations, advisors, and private-sale participants. Disclosed in the MiCA white paper.

Malta Financial Services Authority (MFSA) EU Regulators & Authorities

The MFSA is the Maltese financial services regulator. Malta was an early-mover on crypto-asset regulation with the 2018 Virtual Financial Assets Act. Under MiCA the MFSA applies its established VFA supervisory experience to CASP authorisation; substance bar is moderate.

Market Abuse Regulation (MAR) Market Abuse (MiCA Title VI)

MAR (Regulation (EU) No 596/2014) is the EU framework for market abuse in financial instruments. MiCA Title VI applies a parallel framework to crypto-asset markets, drawing extensively on MAR's approach. For crypto-assets that are MiFID II financial instruments, MAR applies; for MiCA-scope crypto-assets, MiCA Title VI applies.

Regulation (EU) No 596/2014

Market Making Market Abuse (MiCA Title VI)

Market making is the practice of continuously quoting buy and sell prices for a crypto-asset, providing liquidity to the market. Legitimate when carried out under proper market-making arrangements. Distinct from manipulative pattern (e.g., wash trading) that mimics market making.

Market Manipulation Market Abuse (MiCA Title VI)

Market manipulation under MiCA Article 91 includes transactions or orders that give false or misleading signals about supply, demand, or price; transactions affecting the price by employing fictitious devices; dissemination of false information likely to affect prices. Wash trading, spoofing, pump-and-dump all fall within.

MiCA Article 91 ↗

Material Change Notification Process & Authorisation

Under MiCA, CASPs notify the home NCA of material changes to the conditions under which authorisation was granted — new crypto-asset services, change in qualifying holdings, governance changes, material changes in business plan. Some changes require pre-approval, others post-event notification.

MiCA Article 64 ↗

Memorandum of Understanding (MoU) Cross-Border & Passport

An MoU is a formal but non-binding agreement between regulators establishing the terms for information-sharing, joint inspections, and supervisory cooperation. ESMA and EU NCAs have MoUs with regulators in major non-EU jurisdictions covering crypto-asset matters.

Monetary Authority of Singapore (MAS) Non-EU Regulators

The MAS is Singapore's integrated financial regulator. The Payment Services Act 2019 establishes the Digital Payment Token (DPT) framework — licensing for crypto-asset services. Strict consumer-protection focus; institutional clients widely served.

Money Laundering Reporting Officer (MLRO) AML & Travel Rule

The MLRO is the senior officer designated within an obliged entity (including CASPs) with responsibility for AML/CFT compliance — programme oversight, STR filing, regulator engagement. Required to be a substantive role with authority; MLRO appointment is documented in the CASP authorisation file.

Read more: CASP Operations and Lifecycle 2026 — MiCA Passport, Banking, Wind-Down

Multi-Asset Basket Stablecoins (ART / EMT)

The multi-asset basket is the set of reference assets an ART tracks. Single-currency stablecoins are EMTs, not ARTs. Basket composition is disclosed in the ART white paper and reviewed by the NCA. Concentration and asset-quality limits apply under the EBA RTS.

Multi-Party Computation (MPC) Custody & Safeguarding

MPC custody splits a private key across multiple parties using cryptographic protocols so that no single party ever holds the complete key. Used as an alternative to multisig — provides similar security with more operational flexibility.

Multi-Signature Wallet Custody & Safeguarding

Multi-signature (multisig) wallets require multiple cryptographic signatures from independent key-holders to authorise transactions. Removes single-key compromise risk; introduces governance complexity. Standard pattern for CASP cold storage.

National Bank of Belgium (NBB) EU Regulators & Authorities

The NBB is Belgium's central bank. Under MiCA, the NBB supervises credit institutions notifying for crypto-asset services under Article 60, handles AML supervision for financial institutions, and coordinates with the FSMA on substantive MiCA matters.

National CASP Register Process & Authorisation

Each NCA maintains a public register of CASPs authorised in its jurisdiction. Includes authorised service set, qualifying-holdings information, and any supervisory measures. National registers feed into the ESMA EU-wide register.

MiCA Article 109 ↗

National Competent Authority (NCA) EU Regulators & Authorities

Each EU member state designates one or more NCAs for MiCA implementation. The NCA grants CASP authorisation, supervises ongoing compliance, receives passport notifications, and engages with ESMA on supervisory convergence. NCAs vary in style — Bank of Lithuania is fast; CSSF is institutional; BaFin is banking-grade.

MiCA Article 93 ↗

New York State Department of Financial Services (NYDFS) Non-EU Regulators

NYDFS supervises financial institutions in New York State. The BitLicense regime (since 2015) is the most rigorous US state-level crypto-asset framework. Banks chartered under NYDFS may also offer crypto-asset custody under specific guidance.

Read more: United States — crypto licensing

Node DeFi & Crypto Technical

A node is any computer running the software protocol for a specific blockchain. Full nodes verify all transactions and blocks; light nodes verify selectively; archive nodes retain the full historical state. CASPs typically operate validator nodes or RPC infrastructure rather than mining nodes.

Offeror MiCA Defined Terms

An offeror is a natural or legal person, or the issuer, who offers crypto-assets to the public. In primary issuance the issuer and offeror are typically the same. In secondary offerings, a separate offeror may emerge (e.g., an exchange listing a previously-issued token).

Read more: MiCA Stablecoin Regulation Summary 2026 — Title III ART + Title IV EMT

MiCA Article 3(1)(13) ↗

Office of the Comptroller of the Currency (US) (OCC) Non-EU Regulators

The OCC charters and supervises US national banks. The OCC has issued interpretive letters allowing national banks to custody crypto-assets and engage in stablecoin activities. Federal preemption may apply over state-level money-transmitter rules for OCC-chartered entities.

Omnibus Account Custody & Safeguarding

An omnibus account pools client crypto-assets in a shared wallet structure separate from the CASP's own assets. The CASP's internal ledger identifies each client's share. MiCA does not prohibit pooled client wallets: Article 75(7) requires client assets to be held separately from the CASP's own on the ledger, and the register of positions (Article 75(2)) shows each client's entitlement.

Order Book Manipulation Market Abuse (MiCA Title VI)

Order book manipulation covers practices like layering (placing multiple orders at different price levels to mislead other traders) and quote stuffing (rapid order placement and cancellation). Detected through surveillance algorithms; CASPs operating trading platforms have surveillance obligations under MiCA.

Own Funds MiCA Defined Terms

CASP own funds under MiCA Article 67 are the prudential capital the CASP must maintain at all times: the higher of (a) a permanent minimum capital floor by service class (EUR 50k / 125k / 150k) or (b) one-quarter of the previous year's fixed overheads. Must be CET1 quality per CRR Article 26.

MiCA Article 49 ↗

Parent Undertaking MiCA Defined Terms

Under Directive 2013/34/EU referenced by MiCA, a parent undertaking is one that has the right to exercise control over a subsidiary. Group structures with parent-subsidiary relationships have consolidated prudential and reporting obligations under MiCA.

MiCA Article 3(1)(31) ↗

Passport Notification Process & Authorisation

A passport notification under MiCA Article 65 extends a CASP's home-state authorisation to provide services in another EU member state. The CASP notifies its home NCA; the home NCA forwards the information to the host NCA within 10 working days and tells the CASP; the CASP may start on receiving that confirmation, or at the latest from the 15th calendar day after submitting the notification (Article 65(2)-(4)).

MiCA Article 65 ↗

Placing of Crypto-Assets MiCA Defined Terms

Placing is a Class 1 CASP service per MiCA Article 3(1)(23). The CASP places crypto-assets with one or more specified purchasers — typically institutional clients in a private placement. Distinct from public offerings, which trigger different white-paper rules.

MiCA Article 3(1)(23) ↗

Politically Exposed Person (PEP) AML & Travel Rule

A PEP is a natural person who is or has been entrusted with prominent public functions, including heads of state, senior politicians, senior judicial figures, senior military, and similar. Family members and close associates also receive PEP-status. Triggers EDD.

AMLR Article 22-24 ↗

Portfolio Management of Crypto-Assets MiCA Defined Terms

Per MiCA Article 3(1)(25), portfolio management is managing portfolios in accordance with mandates given by clients on a discretionary client-by-client basis where such portfolios include one or more crypto-assets. The MiCA service overlaps significantly with MiFID II portfolio management for securities.

MiCA Article 3(1)(25) ↗

Private Key Custody & Safeguarding

A private key is the cryptographic key that authorises transactions from a crypto-asset address. Possession of the private key is effectively ownership of the assets at that address. CASPs custody private keys on behalf of clients under MiCA Article 75.

Private Sale White Paper & Token Issuance

A private sale is a pre-public allocation of tokens to selected investors (typically VCs, strategic partners). May qualify for the MiCA Article 4(2) exemption for qualified-investor-only offerings or fewer-than-150-persons-per-member-state offerings.

Proof of Reserves (PoR) Custody & Safeguarding

Proof of Reserves is a cryptographic verification that a CASP's on-chain holdings match its liabilities to clients. Typically uses Merkle-tree commitments enabling each client to verify their balance is included in the total. Industry practice post-FTX; MiCA Article 75 reconciliation requirements work alongside.

Proof of Stake (PoS) DeFi & Crypto Technical

Proof of Stake replaces PoW computational competition with economic stake. Validators lock up (stake) crypto-assets and earn rewards for validating transactions correctly. Misbehaviour is penalised by stake forfeiture (slashing). Used by Ethereum (post-Merge 2022), Solana, Cardano.

Proof of Work (PoW) DeFi & Crypto Technical

Proof of Work requires miners to compete computationally to solve cryptographic puzzles, earning the right to add blocks and receive rewards. High energy consumption is the principal criticism. Used by Bitcoin (and a smaller set of remaining PoW chains).

Public Key Custody & Safeguarding

A public key is the cryptographic counterpart to a private key. Derives the wallet address. Safe to share publicly; used by senders to direct transfers to the address. The private key authorises spending; the public key only allows receiving.

Public Sale White Paper & Token Issuance

A public sale is the phase of a token sale open to general investors. Triggers MiCA Title II white-paper requirements unless an Article 4(2) exemption applies. The home NCA receives the white-paper notification at least 20 working days before the sale opens.

Pump and Dump Market Abuse (MiCA Title VI)

Pump-and-dump schemes involve coordinated buying and promotion to inflate a crypto-asset price, followed by rapid sale at the peak by the schemers. Common with low-liquidity tokens. Prohibited under MiCA Article 91; also typically involves dissemination of false information.

Qualifying Holding MiCA Defined Terms

A qualifying holding is any direct or indirect holding in a CASP that represents 10% or more of the capital or voting rights, or makes it possible to exercise a significant influence. Acquiring a qualifying holding, or increasing it to 20%, 30%, 50% or control, requires prior notification to the NCA under MiCA Article 83, with a 60-working-day assessment.

MiCA Article 3(1)(36); Articles 83-84 ↗

Reception and Transmission of Orders MiCA Defined Terms

Per MiCA Article 3(1)(22), this involves receiving from a client an order to buy or sell one or more crypto-assets and transmitting that order to a third party for execution. A Class 1 CASP service that overlaps with brokerage.

MiCA Article 3(1)(22) ↗

Reference Asset Stablecoins (ART / EMT)

The reference asset is what an ART or EMT references for its stable-value claim. For EMTs, the reference asset is a single official currency. For ARTs, the reference asset can be one or more currencies, commodities, or other assets in a basket.

Regulatory Technical Standards (RTS) Process & Authorisation

RTS are EU delegated acts that specify the technical detail of how MiCA primary rules apply. Drafted by ESMA or EBA, adopted by the European Commission. Examples: Commission Delegated Regulation (EU) 2025/305 on the information in a CASP application and (EU) 2025/294 on complaints handling.

Reserve Asset Stablecoins (ART / EMT)

Reserve assets are the individual instruments held in the ART reserve of assets or invested from EMT funds. For EMTs, at least 30% of funds received sits in separate credit-institution accounts and the rest in highly liquid, low-risk instruments in the same currency (Article 54). For ARTs, investment is limited to highly liquid financial instruments (Article 38), with a deposit share of at least 30% per referenced currency set by EBA RTS (Article 36(4)).

MiCA Article 38; EBA RTS ↗

Reserve Custodian Stablecoins (ART / EMT)

Reserve custodians hold the assets backing outstanding ARTs. Under Article 37(3), they must be a CASP providing custody (for crypto-assets), a credit institution, or an investment firm (for financial instruments), a different legal person from the issuer, with custody in place within five working days of issuance and concentration of custodians avoided. EMT funds are safeguarded under EMD2 Article 7.

MiCA Article 37; EBA RTS ↗

Reverse Solicitation Cross-Border & Passport

Reverse solicitation under MiCA Article 61 permits a third-country firm to provide services to an EU client where the client initiated the relationship without solicitation by the firm. Narrowly applied; any subsequent solicitation or marketing brings the relationship within MiCA scope.

Rollup DeFi & Crypto Technical

A rollup is a Layer 2 scaling solution that batches transactions off-chain (or in a sub-chain) before settling them on Layer 1. Two main types: optimistic rollups (Optimism, Arbitrum) and zero-knowledge rollups (zkSync, StarkNet). Reduce gas costs and increase throughput.

Sanctions Screening AML & Travel Rule

Sanctions screening verifies customer and transaction-counterparty identity against EU, UN, OFAC, and other relevant sanctions lists. Required for all CASP transactions and customer onboarding. Specific sanctions-compliance regimes apply for transactions involving sanctioned jurisdictions.

Second Electronic Money Directive (EMD2) Stablecoins (ART / EMT)

EMD2 (Directive 2009/110/EC) is the EU framework for electronic money. Sets rules for EMI authorisation, prudential capital (initial EUR 350k + 2% of average outstanding e-money), and consumer protection. MiCA Title IV applies EMD2 to crypto-asset issuance.

Directive 2009/110/EC ↗

Securities and Commodities Authority (UAE) (SCA) Non-EU Regulators

The SCA is the federal UAE securities and commodities regulator. Supervises virtual asset service providers at the federal level — distinct from VARA (Dubai), DFSA (DIFC), and FSRA (ADGM). The UAE's virtual-asset regulatory map is multi-layered by emirate and free zone.

Securities and Exchange Commission (US) (SEC) Non-EU Regulators

The SEC supervises securities markets in the United States. The 2024-2026 regulatory direction has clarified that many crypto-assets fall within securities classification under the Howey test, triggering registration and disclosure obligations. The SEC v Coinbase, SEC v Binance cases shape the boundary.

Security Token Offering (STO) White Paper & Token Issuance

An STO is a token sale where the token is a financial instrument under MiFID II — typically a tokenised security. Falls under the Prospectus Regulation (EU) 2017/1129, not MiCA. May qualify for the DLT Pilot Regime if traded on a DLT-MTF.

Seed Phrase Custody & Safeguarding

A seed phrase (or recovery phrase) is a sequence of 12 or 24 dictionary words that encodes a private key. BIP-39 standard. Losing the seed phrase loses access to the wallet permanently; sharing it transfers control. Used for self-hosted wallet backup.

Segregation Custody & Safeguarding

Segregation under MiCA Article 75(7) requires CASPs to hold client crypto-assets separately from their own on the distributed ledger, to segregate them legally so creditors have no recourse in insolvency, and to segregate them operationally. Two structures meet it: individual segregation (one wallet per client) or omnibus segregation (pooled client wallets with a register of positions).

Read more: Crypto Custody Segregation Rules — MiCA Practitioner Guide

MiCA Article 75 ↗

Self-Hosted Wallet AML & Travel Rule

A self-hosted wallet (also called non-custodial or unhosted) is one where the user holds the private keys directly rather than entrusting them to a CASP. The TFR sets specific data-collection rules for transfers between CASPs and self-hosted wallets above EUR 1,000.

Directive (EU) 2024/1640

Smart Contract DeFi & Crypto Technical

A smart contract is computer code deployed on a blockchain that executes automatically when specific conditions are met. The technical primitive of DeFi protocols, NFTs, tokenisation, and most non-payment crypto-asset use cases. Different jurisdictions treat smart contracts differently for legal-enforceability purposes.

Spoofing Market Abuse (MiCA Title VI)

Spoofing is placing buy or sell orders with no intent to execute them, designed to create false impressions of supply or demand that influence other participants. Falls within MiCA Article 91 market manipulation. Detected through order-book pattern analysis.

Stress Testing for Reserves Stablecoins (ART / EMT)

Stress testing applies severe but plausible scenarios to the reserve and redemption flows, such as interest-rate shocks, market dislocations and runs. All ART issuers must stress test regularly, and the NCA can raise own funds by 20-40% on the results (Article 35(5)); significant issuers also run liquidity stress tests (Article 45(4)).

Sub-Custody Custody & Safeguarding

Sub-custody is delegation of client crypto-asset custody to a third-party custodian. MiCA Article 75(9) allows it only with other CASPs authorised under Article 59 for custody, and clients must be informed. The original CASP stays liable to its clients for losses attributable to it (Article 75(8)).

MiCA Article 75(8)-(9) ↗

Subsidiary Undertaking MiCA Defined Terms

A subsidiary is an undertaking controlled by a parent within the meaning of Directive 2013/34/EU. Subsidiaries of credit institutions may benefit from MiCA Article 60 notification where the parent is authorised under the CRR.

MiCA Article 3(1)(31) ↗

Supervisory College Process & Authorisation

Under MiCA, a supervisory college is set up by the EBA for each issuer of a significant asset-referenced or e-money token (Article 119). The EBA chairs it; members include ESMA, the home authority, the ECB and the authorities of the main CASPs and banks involved. Colleges give non-binding opinions (Article 120). MiCA does not set up colleges for CASPs.

MiCA Articles 43, 56, 85 ↗

Supervisory Cooperation Cross-Border & Passport

Supervisory cooperation includes intra-EU NCA cooperation under ESMA convergence, bilateral memoranda with non-EU regulators (FCA, FINMA, SFC, MAS, etc.), and information-sharing for cross-border investigations. Underpins effective supervision of cross-border crypto-asset business.

Suspicious Activity Report (SAR) AML & Travel Rule

SAR is the US terminology for the AML report; STR is the EU equivalent. Both are mandatory filings to the relevant FIU when transactions raise AML concerns. US SARs go to FinCEN; UK SARs go to NCA; EU STRs go to the home-state FIU.

Suspicious Transaction Report (STR) AML & Travel Rule

An STR is the formal report obliged entities file to the national FIU when a transaction or customer behaviour raises money-laundering or terrorism-financing concerns. Filing is mandatory; failure to file is a substantive AML breach. Confidentiality requirements protect the entity from tipping-off concerns.

Swiss Financial Market Supervisory Authority (FINMA) Non-EU Regulators

FINMA is the Swiss financial regulator. Switzerland's crypto-asset framework operates outside MiCA via the 2021 DLT Act, the AMLA SRO regime for AML supervision, and the proposed crypto-institution licence (expected 2026-2027). Strong reputational signal but no EU passport.

Third-Country Firm Cross-Border & Passport

A third-country firm is a non-EU CASP. Cannot serve EU clients via direct outbound marketing — MiCA generally requires EU authorisation. Reverse solicitation (where the EU client initiates the contact) is the principal exception, narrowly applied per Article 61.

MiCA Article 61 ↗

Token Generation Event (TGE) White Paper & Token Issuance

A TGE is the technical event when crypto-asset tokens are minted on a blockchain for the first time. Often coincides with the public token sale launch. The TGE date is significant for vesting schedules, lock-up periods, and tax treatment in many jurisdictions.

Token Sale White Paper & Token Issuance

A token sale is the primary distribution of crypto-assets to investors or users. MiCA Title II applies to utility/generic token sales; Title III to ART issuance; Title IV to EMT issuance. Each route has its own white-paper and notification requirements.

Read more: MiCA Stablecoin Regulation Summary 2026 — Title III ART + Title IV EMT

Tokenomics White Paper & Token Issuance

Tokenomics covers the economic design of a crypto-asset: total supply, distribution mechanism, vesting schedules, utility within the protocol, incentive structures (staking rewards, fee distribution), and any burn mechanisms. Material disclosure component of the MiCA white paper.

Total Supply White Paper & Token Issuance

Total supply is the total number of tokens that exist at a given moment — includes circulating supply plus tokens in vesting contracts, reserves, locked allocations. Different from maximum (cap) supply, which is the lifetime ceiling.

Trading Platform for Crypto-Assets MiCA Defined Terms

Per MiCA Article 3(1)(18), a trading platform for crypto-assets is a multilateral system operated or managed by a CASP that brings together multiple third-party buying and selling interests in crypto-assets in a way that results in a contract.

Ultimate Beneficial Owner (UBO) AML & Travel Rule

UBO is the natural person who ultimately owns or controls a customer through a chain of intermediate entities. Where the ownership chain has multiple layers, the UBO is identified by tracing through each layer until a natural person controlling 25%+ is found.

Unhosted Wallet AML & Travel Rule

"Unhosted wallet" is the term used in EU and FATF documents for what the industry typically calls a self-hosted or non-custodial wallet. The user controls the private keys directly. Same regulatory implications as self-hosted under TFR and AMLR.

Unlawful Disclosure Market Abuse (MiCA Title VI)

Unlawful disclosure of inside information is prohibited under MiCA Article 90 — disclosing inside information to any other person except where the disclosure is made in the normal exercise of employment, profession, or duties. Even unintentional disclosure can breach.

Utility Token MiCA Defined Terms

A utility token is a type of crypto-asset that is only intended to provide access to a good or service supplied by its issuer. MiCA Title II governs the public offering of utility tokens — requiring a white paper but lighter than the ART or EMT regime. Tokens marketed as "utility" but with investment characteristics may fall under MiFID II as securities.

Validator DeFi & Crypto Technical

A validator is a node operator on a Proof of Stake blockchain who stakes crypto-assets to validate transactions and propose blocks. Validators earn staking rewards and face slashing for misbehaviour. Running a validator may itself fall within MiCA staking-as-a-service scope if operated commercially.

Vesting Schedule White Paper & Token Issuance

A vesting schedule defines how locked-up tokens are released over time — typically monthly or quarterly cliff-and-vesting structures over 1-4 years. Required disclosure in the MiCA white paper. Affects circulating supply and market dynamics post-TGE.

Virtual Assets Regulatory Authority (Dubai) (VARA) Non-EU Regulators

Wallet (Custodial / Non-Custodial) DeFi & Crypto Technical

A custodial wallet means a CASP holds the private keys on behalf of the user — under MiCA Article 75 safeguarding rules. A non-custodial (self-hosted) wallet means the user holds the keys directly — MetaMask, Trust Wallet, hardware wallets. The custody distinction drives the regulatory scope.

Warm Wallet Custody & Safeguarding

Warm wallets sit between hot and cold storage. Online but with additional security controls (multi-sig requirements, time delays, withdrawal limits). Used as withdrawal buffer to refill hot wallets from cold storage.

Wash Trading Market Abuse (MiCA Title VI)

Wash trading is the practice of buying and selling the same crypto-asset between accounts under common control to create the false appearance of trading volume. Prohibited under MiCA Article 91 market-manipulation framework. Frequently detected through surveillance pattern recognition.

White Paper Notification Process & Authorisation

White paper notification is the procedure for submitting a crypto-asset white paper to the home NCA at least 20 working days before a public offering (Title II) or seeking admission to trading. NCAs may object during the window; do not formally approve content. ART/EMT white papers under Title III/IV require approval.

MiCA Article 8 (Title II) ↗

Wrapped Token DeFi & Crypto Technical

A wrapped token is a tokenised representation of one asset on a different blockchain. Examples: wBTC (Bitcoin on Ethereum), stETH (staked ETH derivatives). The wrapping entity custodies the underlying asset; MiCA scope depends on the wrapper's structure and stability characteristics.

Yield Farming DeFi & Crypto Technical

Yield farming is the practice of moving crypto-assets between DeFi protocols to maximise returns through liquidity provision, lending, staking, and incentive distributions. Activities often combine multiple protocols. Subject to smart-contract risk and yield-token volatility.

Zero-Knowledge Proof (ZK) DeFi & Crypto Technical

A zero-knowledge proof allows one party to prove to another that a statement is true without revealing any information beyond the validity itself. Used in ZK-rollups for scaling, privacy coins, and emerging compliance use cases (proof of solvency, proof of credentials).
