Sanctions screening for crypto wallets
Every transaction your platform settles is a sanctions risk. A single counter-party hit on the OFAC SDN list can land your firm on the wrong side of a $millions enforcement action. Screening every withdrawal address against Treasury's real-time list is the cheapest insurance you'll ever buy.
What we screen against
Our system ingests the OFAC SDN XML feed every hour, normalizing 16 chain tickers (BTC, ETH, USDT-ERC20 + Omni, TRX, XMR, LTC, BCH, SOL, and more) and diffing against the prior snapshot. Address additions and removals fire alerts within minutes.

Where we fit vs. Chainalysis
- Chainalysis Free APIanswers “is this address sanctioned right now?” — one lookup at a time, pull-only. We don't compete with that; the widget above does the same thing free. What we sell is the next step: monitoring.
- Chainalysis Enterprise($25,000+/yr) adds transaction-graph analysis, risk scoring, and investigation tooling. We don't replace that — teams that need it should buy it, and many of them run us alongside for OFAC push alerts.
- OFAC Alert (from $99/mo, cancel anytime) covers the gap in between: continuous monitoring, push alerts via webhook / email / Telegram, and an event timeline — scoped to the addresses you actually care about.
