Agent pays through a sanctioned exchange wallet

What happens when an agent routes a payment through a wallet controlled by a designated exchange, the risk, and the control.

TL;DR

TL;DR: Paying through a wallet tied to a designated exchange such as Garantex or SUEX is a transaction with a blocked party under strict liability. Screen the wallet before routing and BLOCK flagged matches.

What happens

An agent routes a payment through an exchange wallet for liquidity or speed. If that wallet belongs to a designated exchange on the SDN List, the agent transacts with the exchange itself, even when the ultimate recipient is legitimate. The intermediary is not neutral when it is the designated party.

The risk

Designated exchanges such as SUEX and Garantex sit on the SDN List. OFAC enforces under strict liability, so intent is not required, and civil penalties start at $356,000 per violation. The 50 Percent Rule extends the block to entities 50% or more owned by a blocked person, so a wallet behind a front still triggers the violation.

The control

Screen every wallet in the payment path. agentmail checks an address against 947 OFAC-listed crypto wallets in one call under 100 ms, returning ALLOW for a clean wallet and BLOCK for a designated one. The SCREEN, SCORE, STOP, STAMP protocol halts the flow at the STOP gate, and dispute_open documents any unclear match instead of letting the agent route around it. Logging each check turns the path review into evidence the wallet was screened before routing.
