Optimistic Rollup Bridge Security Audit

We begin with a deep dive into your bridge's design, threat model, and documentation. This foundational review ensures our testing targets the most critical attack vectors, from message relayer logic to fraud proof window assumptions.

Leveraging proprietary and industry-standard tools (Slither, MythX), we perform static and dynamic analysis on your smart contracts. This catches common vulnerabilities (reentrancy, integer overflows) and gas inefficiencies early in the process.

Our senior auditors conduct line-by-line manual review of core bridge components (L1/L2 contracts, message libraries). We simulate complex, multi-transaction exploits to test edge cases in withdrawal finality and challenge mechanisms.

We analyze the cryptoeconomic security of your system, evaluating staking slashing conditions, sequencer profitability, and validator incentives. This ensures the system remains secure under adversarial market conditions and network congestion.

For core security modules (e.g., fraud proof verification, state root validation), we apply formal methods to mathematically prove the correctness of invariants and security properties, eliminating whole classes of bugs.

We provide clear, prioritized findings with remediation guidance. After fixes are implemented, we perform a targeted re-audit of the changes to verify vulnerabilities are resolved without introducing new risks.

Our security team has collectively secured over $5B+ in cross-chain TVE. We apply hard-won lessons from real-world bridge exploits to proactively fortify your architecture against known and novel attack patterns.

Receive clear, prioritized findings with line-by-line code fixes and proof-of-concept exploit scripts. We provide remediation guidance that integrates seamlessly with your development workflow, not just a list of problems.
