OFAC Stablecoin Compliance Glossary Part 1
Core terms for applying OFAC sanctions rules to stablecoin payments made by AI agents.
TL;DR
TL;DR: A stablecoin is a crypto token designed to hold a stable value, such as USDC. OFAC sanctions apply to stablecoin transfers exactly as they apply to fiat, so agents paying in stablecoins must screen the recipient first.
What stablecoin compliance is
A stablecoin is a cryptocurrency whose value is pegged to a reference asset, often a fiat currency like the US dollar, making it a common medium for agent payments. Compliance for stablecoin payments means applying the same sanctions screening that fiat rails require: identify the recipient, check it against OFAC lists, and block any transfer to a listed party. The convenience of stablecoins does not create an exception to sanctions, and OFAC enforces strict liability.
Why it matters for agent payments
Payment protocols such as x402, AP2, ACP, and Coinbase AgentKit move money, including stablecoins, but they do not screen the recipient. That gap is the agent's problem. sanctionsai.dev fills it: a screening API that integrates with Base/USDC and returns clean or flagged in one HTTP call under 100 ms. It checks 947 OFAC-listed crypto wallets, so an agent paying in USDC can stop a transfer before it reaches a blocked address.
