To find logic bugs missed by automated scanners, perform a deep security audit using the Feynman technique to question the purpose, ordering, and consistency of every code decision from first principles.

The Feynman technique for code review involves systematically interrogating code logic, invariants, and state transitions across multiple functions to challenge assumptions and expose hidden logic flaws from first principles.

Yes, you can audit smart contracts in Solidity, Rust, Move, and other languages because the auditing approach is language-agnostic and focuses on universal logic principles rather than syntax-specific patterns.

To perform a deep logic audit for race conditions, analyze state transitions and invariants across multiple transactions and functions, systematically questioning the reasoning behind every line of code.

Use first-principles auditing instead of pattern-matching security tools when you need to uncover subtle economic exploits or complex logic flaws that require challenging hidden assumptions and invariants.

The limitation of using the Feynman technique for vulnerability discovery is that it requires systematic, deep interrogation of every decision and state transition, making it a highly manual process focused on logic rather than automated pattern detection.
