Documentation

Returns a 0-100 risk score (higher = riskier) for a Base wallet, derived from on-chain history: wallet age, activity depth, funding source, counterparty concentration, holdings, and known-flagged interactions. riskLevel buckets the score as low (0-33), medium (34-66), or high (67-100). Pass a checksummed or lowercase EVM address. Powered by Alchemy on Base mainnet.
