Tips from the field

  • 1.

    Run Slither first on every audit. It catches low-hanging fruit and gives you a codebase overview.

  • 2.

    Combine static analysis with fuzzing. Static tools find code patterns; fuzzers find edge cases.

  • 3.

    Reproduce past exploits to understand attack patterns. DeFiHackLabs is invaluable.

  • 4.

    Use Tenderly to trace live transactions when investigating suspicious behavior.

  • 5.

    Build your own checklist from audit reports. Solodit is a goldmine for this.
