The formal verification specialist — Certora Prover checks custom invariants against the actual bytecode/spec, catching state-machine and invariant bugs manual review can miss; the standard complement for high-TVL DeFi (Aave, Compound-lineage protocols) where "no path violates solvency" matters more than a findings list.
Gemini Premier provider of mathematical formal verification via the Certora Prover, delivering absolute invariant proof guarantees for high-value DeFi protocols managing high TVL.
Where Certora falls short, per the models
- Claude Not a substitute for a manual audit — value depends on how good your written specs are, and the spec-writing effort is significant; wrong choice as your only audit or for teams without time to invest in formal specs.
- Gemini Requires writing specialized specifications in CVL and steep formal logic overhead, making it impractical for standard or rapidly changing codebases.
