Formal verification

Formal verification · Verification

Certora AutoProver is an AI bot that automates parts of formal verification for smart contracts. Verification engineers use it to generate and run checks with less manual specification work.

K Semantics of the Ethereum Virtual Machine (EVM)

KEVM is the K-framework executable semantics of the EVM: point it at bytecode when you need conformance-checked execution, symbolic exploration, gas reasoning, or proofs that track Ethereum's rules closely.

hax

hax is a tool for high assurance translations of a large subset of Rust into formal languages such as F* or Rocq.

Kontrol - formal verification tool based on Foundry and KEVM

Kontrol lifts Foundry property tests into KEVM-backed proofs so you can chase formal guarantees with less hand-written specification work than raw KEVM alone.

Act

Act is Ethereum's declarative specification language and toolchain for describing all behaviors of an EVM program so SMT solvers, theorem provers, or economic analysis tools can reason about bytecode-level correctness and incentive compatibility, including automatic refinement proofs against concrete implementations.

Verifereum

Verifereum connects Ethereum smart contracts to HOL4-backed theorem proving so you can aim at very strong correctness claims when automated SMT approaches are not enough.

Certora Prover

Certora Prover is a cloud formal-verification service that checks specifications written in CVL against deployed contract code. Verification engineers use it to prove that a contract holds stated properties for all inputs.
