OFAC screening for bridge operators
A bridge moves value across chains, so both the source and the destination addresses need a screen.
TL;DR
TL;DR: Bridge operators facilitating cross-chain transfers must screen both source and destination addresses for every transfer, because value is being moved on behalf of both parties.
Why both ends matter
A bridge transfer has two endpoints, and either one can be a sanctioned wallet. Screening only the source leaves the destination exposed, and screening only the destination misses a blocked sender. Both addresses are part of the same value movement.
What to screen
- The source wallet against 947 OFAC-listed crypto wallets.
- The destination wallet against the same list.
- Names against 19,218 SDN names where known.
- Jurisdiction across 16 tracked regions.
Practical controls
Screen both addresses before locking or releasing funds, and re-screen as data updates hourly. sanctionsai.dev returns clean equals ALLOW and flagged equals BLOCK, and keeps a STAMP record of each clean transfer for audit.
