Crypto Sanctions Screening — OFAC Exposure Checks
Compliance teams cannot afford to process transactions involving sanctioned entities. OnChainRisk screens a wallet address against OFAC SDN entries where supported and surfaces both direct and indirect exposure — including 1-hop and 2-hop connections to sanctioned addresses on supported networks, with coverage that varies by network. The same screening workflow also helps analyze terrorism-related blockchain transactions. UAE virtual-asset businesses can see wallet screening for UAE VASPs.
How Sanctions Screening Works
Paste the Address
Enter a wallet address. OnChainRisk auto-detects the network — Ethereum, Tron, Bitcoin, Solana, and other supported networks.
OFAC SDN Match
The address is checked against OFAC SDN entries where supported, including designations such as Tornado Cash, Blender.io, Garantex, and Hydra Market. Coverage varies by network.
Indirect Exposure Scan
Beyond direct matches, the system traces 1-hop and 2-hop counterparties to surface indirect sanctioned-address exposure where supported.
