MiCA compliance and the crypto Travel Rule
MiCA gives the EU a single rulebook for crypto, and the Travel Rule decides what data must accompany every transfer. Here is what a MiCA licence requires and how to prepare.
- MiCA (Markets in Crypto-Assets) is the EU's unified regime licensing crypto-asset service providers across all member states.
- A MiCA licence lets an authorised CASP passport its services across the EU, but carries AML, custody and disclosure obligations.
- The crypto Travel Rule requires originator and beneficiary data to travel with transfers above set thresholds — including to unhosted wallets.
What is MiCA?
MiCA — the Markets in Crypto-Assets regulation — is the European Union's single, harmonised framework for crypto. It replaces a patchwork of national regimes with one rulebook covering token issuers and crypto-asset service providers (CASPs): exchanges, custodians, brokers and wallet providers operating in the EU.
Its aim is a level playing field with clear obligations around authorisation, capital, custody of client assets, market-abuse rules and consumer disclosure — the kind of certainty institutional players said they needed before committing to on-chain finance.
Who needs a MiCA license?
Any business providing crypto-asset services to EU customers generally needs to be an authorised CASP under MiCA. A MiCA licence is valuable because it passports: authorisation in one member state lets you serve the whole EU without 27 separate approvals. In return, the licence carries ongoing obligations — AML controls, safeguarding of client funds, governance and reporting — and it must be maintained, so MiCA licence renewal and continued compliance are part of the cost, not a one-time gate.
The crypto Travel Rule under MiCA
The crypto Travel Rule requires that identifying information about the originator and the beneficiary travels alongside a transfer of crypto-assets. Under the EU's Transfer of Funds Regulation, which sits beside MiCA, CASPs must collect and transmit this data — and, critically, the rule extends to transfers involving unhosted (self-custody) wallets above set thresholds.
The hard part is the “sunrise problem”: the rule only works if both sides implement it, and adoption is uneven across jurisdictions. Verifying an unhosted wallet's control, and screening the counterparty before the transfer settles, is where compliance actually bites. Our deeper write-up on the Travel Rule and MiCA covers the data fields and thresholds in detail.
Getting MiCA compliant
Practically, MiCA compliance comes down to a few workstreams: secure authorisation as a CASP, stand up AML/KYC controls, safeguard client assets, and implement the Travel Rule for transfers — including screening counterparties and verifying unhosted wallets. The on-chain controls are where tooling helps most.
FIN-TECHAI's Sentinel provides the wallet and transaction screening a Travel-Rule and AML programme needs — sanctions matches, mixer exposure and a defensible, auditable risk score — so an EU CASP can evidence exactly why a transfer was allowed or held.
