EXPERTISE MATTERS
Why Choose a Specialized Bridge Audit
General audits miss the unique complexities of cross-chain messaging and asset custody. Our focused methodology delivers the security depth your bridge requires.
01
Protocol-Specific Vulnerability Knowledge
We target bridge-specific risks like reentrancy in message relayers, signature malleability in multi-sigs, and consensus failures in light clients—issues generic audits often overlook.

Coverage of Top 10 Bridge Risks
02
Economic & Incentive Analysis
Beyond code, we audit your bridge's economic security: validator slashing conditions, liquidity pool imbalance risks, and oracle manipulation scenarios that could lead to insolvency.

03
Cross-Chain State Verification
We rigorously test the consistency and finality of state proofs across heterogeneous chains (EVM, Cosmos, Solana), ensuring messages cannot be forged or replayed.

Upgradeability & Governance Security
Bridge admin keys and upgrade mechanisms are critical single points of failure. We design and audit secure multi-sig timelocks and decentralized governance controls.

Integration & Dependency Review
We audit not just your core contracts, but the external oracles, relay networks, and liquidity pools your bridge depends on, identifying systemic risk.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production on EVM, Solana, and Cosmos ecosystems.
We deliver production-ready smart contracts with formal verification and comprehensive audit trails. Our engineers specialize in Solidity, Rust (Seahorse/Anchor), and CosmWasm to meet your chain requirements.
- Security-First Architecture: Built with
OpenZeppelinstandards and battle-tested patterns. - Gas Optimization: Contracts are optimized for up to 40% lower execution costs.
- Full Audit Support: Includes unit/integration tests and preparation for third-party audits from firms like CertiK or Quantstamp.
From token standards (
ERC-20,ERC-721) to complex DeFi primitives, we ensure your logic is secure, efficient, and upgradeable.

Frequently Asked Questions
Get clear answers on our specialized audit process, timeline, and security guarantees for your cross-chain bridge.
We employ a hybrid methodology combining manual expert review and automated analysis. Our process includes: 1) Architecture Review of the zero-knowledge or trusted execution environment (TEE) integration, 2) Logic & Math Verification of cryptographic circuits or enclave operations, 3) Economic & Game Theory Analysis for bridge incentives and validator security, and 4) Integration Testing with mainnet forking. We've secured over $2B+ in cross-chain assets using this approach.
