What Is Wallet Screening?
The wallet-screening mechanic, explained for builders.
Overview
Wallet screening is the check that runs before a transfer: is this destination address on a sanctions list? Exact match against the SDN list — deterministic, sub-100 ms, done.
How it works
- You call the API with the destination address
- The engine matches against 947 OFAC-listed wallets (exact, no fuzzy on addresses)
- Result: clean (proceed) or match (block/review)
- Every check is logged for the audit trail
Why it matters for agents
An agent signs transfers without a human looking. Wallet screening is the automated screen that runs every time — the wallet checker demonstrates it for free.
The limits
Wallet screening covers addresses on the list. Name screening and jurisdiction checks cover the rest — screening is one layer of a compliance program.
