YOUR SECURITY FOUNDATION
Why a Specialized Messaging Audit is Critical
Cross-chain messaging protocols are high-value targets. A generic smart contract audit misses the complex, protocol-specific attack vectors inherent in bridging logic, relayer networks, and state synchronization. Our specialized audit provides the targeted security validation your infrastructure demands.
Choose the right level of security coverage for your protocol

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
We architect and deploy custom smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana, ensuring security, gas efficiency, and scalability from day one. Our contracts are built with Solidity 0.8+ or Rust, using battle-tested patterns from OpenZeppelin and rigorous internal audits.
- End-to-End Development: From specification and architecture to deployment and verification on Etherscan/Solscan.
- Security-First: Multi-stage review process, integration with tools like
SlitherandMythX, and preparation for formal audits. - Gas Optimization: Expert tuning to minimize transaction costs, critical for user adoption and protocol economics.
Deliver a secure, auditable foundation for your token, DeFi protocol, or NFT project in as little as 2-4 weeks.
Why Cross-Chain Protocols Need Specialized Scrutiny
Messaging Audit vs. Generic Smart Contract Audit
Generic smart contract audits miss critical attack vectors specific to cross-chain message passing. Our protocol audit is engineered for LayerZero, Axelar, Wormhole, and CCIP environments.

|---|---|---|
Message Relayer & Validator Logic | ||
Cross-Chain State Consistency | Surface-level | In-depth formal verification |
Gas Oracle & Fee Mechanism Review | ||
Governance & Upgrade Path Security | ||
Time to Report | 2-3 weeks | 10-15 business days |
Deliverables | Vulnerability report | Report + Exploit PoC + Mitigation Guide |
Post-Audit Support | Optional add-on | 30-day consultation included |
Typical Cost for a Protocol | $15K - $30K | $25K - $75K |
Ideal For | Simple dApps, single-chain tokens | Bridges, omnichain dApps, cross-chain DeFi |

Cross-Chain Messaging Audit FAQs
Get clear answers to the most common questions CTOs and technical leads ask when selecting a security partner for their cross-chain protocol.
We employ a multi-layered methodology combining manual expert review with automated analysis. Our process includes: (1) Threat modeling specific to bridging and message passing, (2) In-depth line-by-line code review of core relayers, verifiers, and governance, (3) Automated testing for common vulnerabilities (reentrancy, oracle manipulation), (4) Scenario analysis for chain reorganizations and consensus failures, and (5) Economic security review of staking, slashing, and incentive mechanisms. This approach has secured over $2B+ in cross-chain TVL.
