It is a broad set of rules that financial firms, including most crypto exchanges, have to follow. In practice it means platforms monitor transactions, file suspicious activity reports, and may freeze funds linked to known bad actors. AML rules sit alongside KYC and are a major reason exchanges ask the questions they do. ## Regulatory context AML rules in crypto follow the Financial Action Task Force (FATF) standards and are enforced by national regulators such as the FCA, FinCEN, and the European Banking Authority. ## Related terms - [KYC](https://fudfomo.co/glossary/kyc): Know Your Customer.
