PROTOCOL-LEVEL AUDIT
Comprehensive Bridge Security Review
Our deep-dive security assessment for optimistic rollup bridges identifies critical vulnerabilities before they become exploits, ensuring your cross-chain infrastructure is resilient and trustworthy.
01
Smart Contract & Protocol Audit
In-depth review of your bridge's core smart contracts (deposit, withdrawal, fraud proof, state root verification) and protocol logic for reentrancy, access control, and economic vulnerabilities.

02
Economic & Incentive Analysis
Stress-test the bridge's economic security model. We analyze validator/staker incentives, withdrawal delay assumptions, and fraud proof slashing conditions to prevent economic attacks.
