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

1

Paste the Address

Enter a wallet address. OnChainRisk auto-detects the network — Ethereum, Tron, Bitcoin, Solana, and other supported networks.

2

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.

3

Indirect Exposure Scan

Beyond direct matches, the system traces 1-hop and 2-hop counterparties to surface indirect sanctioned-address exposure where supported.

4

Export Compliance Report

Download a timestamped PDF or CSV report documenting the screening result, suitable for auditors and regulators.
