TRAIL OF BITS

Tool	What It Does	When to Use
Slither	Static analysis for Solidity/Vyper	Always — run first
Echidna	Property-based fuzzer (write invariants, it breaks them)	Write 3-5 invariants before reading code
Medusa	Next-gen fuzzer, multi-core, parallel corpus	Deeper campaigns after Echidna
Manticore	Symbolic execution — confirms if a path is truly reachable	Specific PoC confirmation
Halmos	Symbolic unit testing — proves for ALL inputs	Math-heavy functions
