INSTITUTIONAL-GRADE RIGOR
Our Audit Methodology
A systematic, multi-layered approach designed to identify critical vulnerabilities in cross-chain relay systems, providing the confidence required for high-value institutional operations.
01
Architecture & Design Review
We analyze your relay's system design, threat models, and economic incentives before a single line of code is reviewed, identifying fundamental flaws in logic and security assumptions.

02
Automated Vulnerability Scanning
Leverage proprietary and industry-standard static & dynamic analysis tools to perform an initial sweep for common vulnerabilities (reentrancy, overflow) across all supported chains.

SECURE & AUDITED
Custom Smart Contract Development
Production-ready smart contracts built for security, gas efficiency, and compliance.
We architect and deploy custom Solidity/Rust smart contracts for tokens, DeFi protocols, and NFT ecosystems. Every contract includes formal verification and a comprehensive audit report from our in-house security team before deployment.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
- Gas Optimization: Average 30-50% reduction in transaction costs versus unaudited code.
- Compliance Ready: Built-in support for
EIP-2612permits, upgradeability patterns, and admin controls.
From initial spec to mainnet deployment, we deliver battle-tested contracts that form the secure foundation of your protocol.

Frequently Asked Questions
Get clear answers about our security review process, methodology, and what to expect when you engage Chainscore Labs.
We employ a hybrid methodology combining manual expert review with automated analysis. Our process includes: 1) Architectural threat modeling focused on message validation and relay trust assumptions. 2) Line-by-line code review of core relay logic, governance, and upgrade mechanisms. 3) Automated static analysis (Slither, MythX) and custom fuzzing for invariant testing. 4) Economic and game-theoretic analysis of validator/staker incentives. This multi-layered approach, refined across 50+ cross-chain projects, ensures we identify both technical vulnerabilities and systemic risks.
