Formal Verification
We mathematically prove your critical contract properties hold across every possible state, not just the ones you tested. Supported on SVM, EVM, and Sui-based chains.
REQUEST FORMAL VERIFICATIONTHE CHALLENGE
Testing finds bugs. It can't prove their absence.
Formal verification isn't a replacement for a smart contract audit. It's the layer above it. Testing covers the cases you think of. Formal verification covers every case that can exist.
For protocols where a single edge case can drain funds, that distinction matters.
HOW IT WORKS
Our Process
Specification Design
We collaborate with your team to define precise rules and properties your code must satisfy, tailored to your business logic.
Invariant Extraction
We formalize critical invariants - like balance preservation, access controls, and no-loss guarantees - into machine-checkable specifications.
Model Preparation
We preprocess your contracts and dependencies into prover-compatible formats, optimizing for clarity and soundness.
Proof Execution
We run your specs through industrial-grade formal verification engines to automatically detect violations or confirm correctness.
Issue Triaging & Remediation
We analyze any failing proofs, assist in diagnosing root causes, and iteratively refine specs or code to ensure all checks pass.
