What is Travel Rule?
The Travel Rule is a regulatory requirement that financial institutions share sender and recipient information for transactions above certain thresholds — extended to cryptocurrency transfers to combat money laundering.
WHY IT MATTERS
Originally from traditional banking (FATF Recommendation 16), the Travel Rule now applies to crypto: when a Virtual Asset Service Provider (VASP) sends a transfer above a threshold (often $1000), they must share originator and beneficiary information with the receiving VASP.
Implementation challenges: blockchain transfers don't natively carry identity information. Compliance requires separate messaging layers (TRISA, TRP, OpenVASP) that transmit identity data alongside on-chain transfers.
The Travel Rule affects exchanges, custodians, and any regulated crypto service. Pure DeFi (wallet-to-wallet, no intermediary) is generally outside scope, though this interpretation varies.
