De.Fi

De.Fi is a Web3 security and portfolio toolkit combining contract scanning, approval management and a historical exploit database with multi-chain holdings and yield tracking. It serves onchain users who interact with new contracts often, addressing approvals that stay valid after use and leave legacy permissions as an entry point for drains. Dashboards place holdings, profit and loss and approval risk side by side, warning about abnormal contracts before interaction.

The scanner runs static and dynamic checks on bytecode and permissions, scoring risk and flagging honeypots, mint authority and blacklists; approval management aggregates live allowances across chains, ranks them by exposed value and supports one-by-one revocation; the data layer also feeds market data and third-party interfaces. It currently covers over 40 networks and has analysed more than 65,000 contracts. The exploit database groups incidents by technique and labels the affected protocol, loss amount and date.
