Crypto Address Sanctions Checker — OFAC Wallet Screening & AML Risk

The Crypto Address Sanctions Checker performs on-demand OFAC wallet screening and AML risk classification for any EVM blockchain address. Submit one address or a batch, and receive a complete risk profile covering sanctioned status, mixer usage, money laundering, cybercrime, phishing, darkweb activity, fake KYC, and 10+ additional threat categories — all in a single API call. Powered by GoPlus Security (aggregating SlowMist, BlockSec, OFAC SDN list, Chainabuse). $0.01 per address — up to 1,000x cheaper than enterprise alternatives.

Why use Crypto Address Sanctions Checker?

1. OFAC compliance at minimal cost — Screen addresses against the OFAC SDN list and return a sanctioned flag instantly. Avoid onboarding or transacting with sanctioned wallets for as little as $0.01 per check.
2. Pre-onboarding KYC triage — Check every new user's connected wallet at signup — flag high-risk addresses before they access your protocol, exchange, or lending product.
3. Inbound transaction monitoring — Verify sender addresses before crediting deposits, reducing exposure to money laundering flows and mixer-tainted funds.
4. DAO and treasury security — Screen addresses interacting with your multisig to catch phishing wallets, drainers, and cybercrime clusters before they execute.
5. Research and forensics — Trace hack flows, investigate sanctioned cluster activity, and verify counterparty wallets in P2P transactions using the same data sources used by professional blockchain forensics teams.

FAQ

Is this a replacement for Chainalysis KYT or TRM Labs? No — this is a triage tool for early-stage products and research. GoPlus Security aggregates SlowMist, BlockSec, OFAC, and Chainabuse, which covers most known high-risk addresses. For regulated production environments, combine with a commercial provider.

Which EVM chains are supported? Ethereum (1), BSC (56), Polygon (137), Arbitrum (42161), Optimism (10), Base (8453), Avalanche (43114), and Fantom (250). Ethereum has the most comprehensive coverage.

Can I screen addresses automatically on a schedule? Yes. Use Apify Scheduler to run daily batches. Pass your watchlist in addresses and combine with Telegram alerts for instant notifications when a previously clean address becomes flagged.

What if GoPlus has no data for an address? The actor returns risk_level: "unknown" and empty flagged_fields. This does not mean the address is safe — it means it has not yet been reported to any of the aggregated sources.
