Agent pays a sanctioned stablecoin address

What happens when an agent sends stablecoins to a wallet on the OFAC list, the strict-liability risk, and the control.

TL;DR

TL;DR: Paying a stablecoin address on the OFAC SDN List is a transaction with a blocked party under strict liability. Screen the address before sending and BLOCK flagged matches.

What happens

An agent holds a payment instruction with a destination address on a stablecoin network. If that address belongs to a party on the SDN List, the transfer is a direct transaction with a blocked person, regardless of the fact that stablecoins are pegged and move like cash. A pegged value does not make a blocked address any less blocked.

The risk

OFAC publishes 947 OFAC-listed crypto wallets that agents must screen against. Enforcement is strict liability, so intent is not required, and civil penalties start at $356,000 per violation. The 50 Percent Rule blocks entities 50% or more owned by a blocked person, so an address controlled by a front for a blocked owner still violates sanctions.

The control

Screen the destination address before any transfer. agentmail checks a stablecoin address against the listed wallets in one HTTP call under 100 ms, returning ALLOW for a clean address and BLOCK for a flagged one. The SCREEN, SCORE, STOP, STAMP protocol stops a flagged payment at the STOP gate, and a risk_score signal weights ownership risk before funds ever move. Logging the result turns the check into evidence the payment was reviewed before it was sent.
