How to find Solidity vulnerabilities

A practical how-to that shows concrete detection methods: a scanner scans the blockchain for delegate targets and flags implementations that are uninitialized, then checks for SELFDESTRUCT and DELEGATECALL opcodes in bytecode (skipping push literals). Demonstrations use Slither, MythX/Tenderly, Parity trace and local scripts; common pitfalls include admin proxies and ERC‑777 callbacks. Claim: five recurring bug classes account for most finds; the scan yields ~10–20% exploitable hits for manual follow‑up.
