    Bicscan

    Security · Ethereum, Polygon, BNB Chain

    BICScan is a blockchain risk-screening service for checking addresses, contracts and dApp links before you interact with them. Its free tier is limited, and you should treat its scores as a warning signal—not proof that an address is safe.
