Prometheus/Grafana.
Our Bridge Security Audit Methodology
Our structured, multi-layered approach systematically deconstructs your bridge's architecture to identify critical vulnerabilities, ensuring robust security and operational resilience.
Architecture & Design Review
We analyze the bridge's core architecture, consensus mechanisms, and governance models for systemic risks, ensuring a sound foundation before line-by-line code review.
Smart Contract Security Analysis
In-depth manual and automated review of all on-chain logic (Solidity/Vyper) for reentrancy, access control, and economic vulnerabilities, following OpenZeppelin standards.
Relayer & Off-Chain Component Audit
Security assessment of off-chain components, including signer nodes, oracles, and relayer infrastructure, for consensus flaws and availability risks.
Cryptographic & Economic Review
Verification of signature schemes (ECDSA, BLS), randomness sources, and incentive models to prevent cryptographic failures and economic exploits.
Final Verification & Reporting
Delivery of a comprehensive audit report with severity-ranked findings, actionable remediation guidance, and a final verification pass on fixes.
Why a Specialized Bridge Audit is Critical
Cross-chain bridges are the most targeted attack vectors in Web3, requiring deep protocol-specific expertise. Our audits go beyond generic smart contract checks to secure the entire interoperability lifecycle.
Protocol-Specific Vulnerability Detection
We audit for bridge-specific risks like reentrancy in message relays, signature verification flaws, and liquidity pool manipulation that generic auditors miss. Our team has deep experience with Wormhole, LayerZero, Axelar, and Hyperlane architectures.
Economic & Incentive Model Review
We analyze the economic security of your bridge, including validator/staker incentives, slashing conditions, fee mechanisms, and liquidity provider risks to prevent protocol insolvency and governance attacks.
End-to-End Integration Security
Our audit covers the full stack: smart contracts, off-chain relayers, oracles, front-end interfaces, and admin controls. We ensure secure key management and upgrade paths to eliminate single points of failure.
Post-Audit Threat Monitoring
Receive ongoing monitoring for new vulnerabilities specific to your bridge's architecture and dependencies. We provide actionable alerts and mitigation strategies within 24 hours of disclosure.
Clear Remediation & Developer Support
Get prioritized, actionable fixes—not just a report. Our engineers provide direct support to your team to implement critical patches, with re-audits of high-severity issues included.
Comprehensive Audit Scope & Deliverables
Our tiered audit packages are designed to provide the appropriate level of scrutiny, from a foundational review to a full-spectrum security assessment with ongoing support.

Smart Contract Development
Secure, audited smart contracts built by Web3 specialists to power your protocol.
We architect and deploy production-ready smart contracts for DeFi, NFTs, and dApps. Our development process ensures security-first design, gas optimization, and upgradeability from day one.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke contracts for unique use cases. - Security Audits: All code undergoes internal review and can be prepared for third-party audits from firms like CertiK or OpenZeppelin.
- Full Deployment: We handle deployment, verification on Etherscan, and initial testing on testnets and mainnet.
Reduce your time-to-market and technical risk with battle-tested Solidity or Vyper development.
Chainscore Audit vs. Generic Smart Contract Review
Generic smart contract reviews often miss the complex, cross-chain attack vectors unique to bridges. Our audits are engineered specifically for the EVM bridge ecosystem.
| Audit Dimension | Generic Smart Contract Review | Chainscore Bridge Security Audit |
|---|---|---|
Focus & Methodology | General Solidity patterns, basic vulnerabilities | Cross-chain message validation, asset escrow logic, relay security, MEV resistance |
Bridge-Specific Coverage | Limited or none | Full coverage of deposit/withdrawal flows, pause mechanisms, upgradability risks, oracle reliance |
Formal Verification | Rarely included | Critical state transitions and invariants formally verified |
Gas Optimization Review | Basic suggestions | Deep analysis for cross-chain call batching and relay efficiency |
Third-Party Dependency Audit | Surface-level | In-depth review of oracles, relayers, and external libraries |
Final Report Depth | Vulnerability list with generic fixes | Prioritized exploit scenarios, detailed remediation steps, and post-fix verification |
Time to Completion | 1-2 weeks | 3-4 weeks for comprehensive analysis |
Typical Investment | $5K - $15K | $25K - $75K+ (scales with complexity) |
EVM Cross-Chain Bridge Audit FAQs
Get clarity on our specialized audit process for EVM-based cross-chain bridges, designed to secure high-value assets and complex logic.
We employ a four-phase methodology tailored for bridge vulnerabilities: 1) Architecture Review of the entire message-passing and validation flow. 2) Automated Analysis using Slither and custom tools for common patterns. 3) Manual Code Review focused on asset custody, relayers, fraud proofs, and signature verification. 4) Final Report & Remediation Support with severity-ranked findings and actionable fixes. This process has secured over $2.5B+ in bridge TVL.
