Scenario: Agent Pays Through a Sanctioned Exchange

The sanctioned-exchange scenario - every hop in the payment path needs the screen.

The setup

Your agent's payment flow routes settlement through an exchange whose addresses OFAC designated (like Garantex in 2022).

Without screening

• The payment settles through designated addresses
• Transacting with a designated exchange is prohibited
• The operator holds the liability

With screening

1. The wallet screen matches the exchange's designated addresses
2. The payment is blocked before sign
3. The result is logged with the list entry and version
4. The agent surfaces the block instead of settling

The takeaway

Exchanges get designated - their addresses land on the list. The screen must check every hop in the payment path, not just the final destination.
