The Travel Rule for Crypto Payouts: What B2B Senders Must Know in 2026

The Travel Rule requires sender and recipient identity data to accompany crypto transfers, and in 2026 it directly affects any business paying contractors, suppliers, or partners in crypto. This guide breaks down the regulatory picture by region — the EU's no-threshold TFR, the US $3,000 BSA rule plus new GENIUS Act stablecoin obligations, and FATF's $1,000 baseline — and the exact originator/beneficiary data each payout must carry, including the extra step for self-hosted wallets. It then shows how a regulated crypto gateway runs pre-send screening, KYT/AML checks, and the Travel Rule inside the payout flow, so B2B senders stay compliant without building their own compliance stack.
