All projects on Base matching “wallet chain detection”

Address security check — detect malicious wallets, known phishing addresses, scam contracts, and blacklisted entities across all EVM chains. Chain-independent lookup against multi-chain security databases. No API keys needed. Accepts USDC payments on Base and Solana

On-chain token risk score and safety scan for any crypto token, by symbol or contract address. Returns 8 weighted dimensions — holder concentration, top-1 holder identity, holder income share vs protocol revenue, price percentile over 366 days, P/TVL and P/S, supply integrity and mint/freeze authority, DEX+CEX exit liquidity, and multi-wallet clustering / wash-trading detection — each with its raw

A well-formed but invalid address returns `valid:false` — not an error.
