How can I screen blockchain transactions for terrorism-financing risk?

Run involved wallets through sanctions and AML screening to surface direct matches against OFAC, EU, and UN designated-entity lists, plus indirect exposure through one or two hops to flagged entities. OnChainRisk produces a 0-100 risk score per address across 23 networks, attaches sanctions and watchlist signals where applicable, and lets compliance teams export PDF reports for case files. This is a compliance and screening workflow — it generates signals and documentation, not real-world identity attribution. In practice, screening is a layer that feeds your existing KYT, SAR, or law-enforcement liaison process — outputs are inputs to a regulator-facing case, not an independent intelligence assessment. Documentation is the deliverable: each flagged wallet should have a retained screening record showing the list match, hop count, and timestamp.

How to do it

  1. Submit each involved wallet address to the sanctions screening tool.
  2. Check both direct matches (the wallet itself is flagged) and indirect exposure (1-hop and 2-hop counterparties).
  3. Note the 0-100 risk score and any specific watchlist or sanctions match attached to the address.
  4. If any wallet hits a sanctions or watchlist signal, escalate to your compliance, KYT, or law-enforcement liaison process.
  5. Document findings, attach the screening evidence, and export a PDF report for the case file.

What OnChainRisk can help with

  • OFAC, EU, UN sanctions list matching
  • Indirect-exposure screening (1-hop, 2-hop)
  • Cross-chain wallet risk scoring
  • High-level flow review of suspicious funds
  • Exportable PDF reports for compliance use

What it does not claim

  • Real-world identity attribution
  • Surveillance or intelligence-grade capability
  • Operational counter-terrorism tooling
  • Coverage of every chain or every individual sanctioned actor
