PROVEN FRAMEWORK
Our Multi-Chain Audit Methodology
A systematic, protocol-agnostic approach designed to secure complex multi-chain marketplaces. We deliver actionable reports that identify critical vulnerabilities and provide clear remediation paths.
01
Architecture & Design Review
We analyze your cross-chain architecture for systemic risks, including bridge dependencies, message relay security, and state synchronization logic before a single line of code is audited.

Protocols Reviewed
LayerZero, Axelar, Wormhole
Bridge Expertise
02
Automated Vulnerability Scanning
Leverage a suite of proprietary and industry-standard tools (Slither, MythX) for initial triage, identifying common vulnerabilities like reentrancy and integer overflows across EVM, Solana, and Cosmos chains.

Smart Contract Audit FAQs
Get clear answers on our security audit process, timelines, and support for your multi-chain marketplace protocol.
We employ a hybrid methodology combining automated analysis (Slither, MythX) with manual review by senior auditors. The process includes: 1) Architecture review for cross-chain logic, 2) Core contract testing (order matching, asset bridging, fee distribution), 3) Economic security analysis for tokenomics and incentives, and 4) Integration testing with target chains (EVM, Solana, Cosmos). This ensures vulnerabilities like reentrancy, oracle manipulation, and bridge risks are identified.
