| description.long | An open-source block explorer that allows users to search transactions, verify smart contracts, and access analytics across multiple EVM-compatible blockchains from a single interface, with support for hundreds of chains, rollups, L2s, and testnets. | An open-source Python framework that scans smart contract source code for security issues using built-in detectors, generates visual contract analysis reports, and provides an extensible API for writing custom vulnerability checks. Enables developers to catch bugs before deployment and better understand contract behavior. |
