Scenario: Agent Pays a Designated Mixer

The mixer scenario: why designated addresses must be screened before sign.

The setup

Your agent's payment flow routes a transfer through a mixer address that OFAC designated in 2022. The address is on the SDN wallet list.

Without screening

• The payment settles through the designated address
• Interaction with a designated address is prohibited - even via code
• The operator holds the liability

With screening

1. The wallet screen matches the designated mixer address
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

Designated mixer addresses are exactly why the screen must run before the payment - the destination, not the intent, is what the list matches.
