Wallet Screening & Risk Scoring
One API call per address returns sanctions exposure, entity category and a risk tier — live in production across six chains. Sanctions verdicts run against the live OFAC SDN list, refreshed within the hour and covering every chain OFAC publishes addresses for — 16 chains, 989 SDN addresses today, Bitcoin and Monero included. The graph-neural score is trained on the full 835M-address, 15.8B-edge five-chain EVM graph with per-chain normalisation: recall 0.83 on ETH and 0.58 on Tron at a 0.1% population false-positive rate. Base, Arbitrum and Gnosis are covered by zero-label transfer — 0.86 / 0.82 / 0.997 with heads that never saw those chains. Bitcoin is scored by a dedicated feature pipeline over 1.5B addresses. Explainable, not a black box.
