METHODOLOGY
Our Bridge Security Audit Framework
A systematic, multi-layered approach designed to uncover critical vulnerabilities in cross-chain bridges, ensuring the security of billions in digital assets. We go beyond automated scanners with deep protocol analysis.
01
Architecture & Design Review
We analyze the bridge's core architecture for systemic risks, including centralization vectors, upgrade mechanisms, and economic model flaws before a single line of code is written.

Smart Contract Deep Dive
Manual line-by-line review of bridge contracts (deposit, verification, relay) focusing on reentrancy, logic errors, and edge cases in cross-chain message passing.

Expert Answers for Technical Decision-Makers
Layer 2 Bridge Security Audit FAQs
Get clear, technical answers to the most common questions CTOs and engineering leads ask when evaluating a security audit for their cross-chain bridge.
We employ a multi-layered, manual-first methodology tailored for cross-chain systems. This includes: 1) Architecture Review of the entire message-passing and state verification flow. 2) In-depth Code Review of core bridge contracts, focusing on reentrancy, logic errors, and economic attacks. 3) Mathematical Verification of fraud-proof or validity-proof mechanisms (e.g., zk-SNARK circuits, fraud proof games). 4) Integration Testing of the bridge's interaction with external components like oracles and relayers. 5) Economic & Game Theory Analysis to model validator/incentive attacks. We supplement this with automated fuzzing and static analysis tools like Slither and Foundry.
