What Is the FATF “Travel Rule” and How Does It Apply to DEXs?
The Financial Action Task Force (FATF) "Travel Rule" requires financial institutions (including Virtual Asset Service Providers, or VASPs) to obtain and transmit certain required originator and beneficiary information when a crypto transaction exceeds a specified threshold. Applying this to Decentralized Exchanges (DEXs) is challenging because DEXs, being non-custodial, lack the VASP status and the central authority to collect and transmit this data.
Regulators are still debating how to implement the Travel Rule on decentralized protocols, with some focus shifting to the interfaces or "front-ends" that interact with the smart contracts.
