TONTrail of Bits is a security research company that performs blockchain assessments across smart contracts, bridges, nodes, DeFi systems, and offchain components.
Its official service pages emphasize tailored reviews, early stage design assessment, invariant testing, and root cause analysis instead of checklist driven auditing.
