COMPREHENSIVE AUDIT SCOPE
What Our Security Review Covers
01
Architecture & Design Review
We analyze your system's high-level design for cross-chain logic flaws, including message relay patterns, bridge dependencies, and failure modes. This prevents systemic risks that automated tools miss.

BEYOND SINGLE-CHAIN SECURITY
Why a Specialized Cross-Chain Audit is Critical
Cross-chain applications introduce unique attack vectors that generic audits miss. Our specialized reviews target the critical interfaces and assumptions that secure your multi-chain architecture.
01
Bridge & Messaging Protocol Security
We conduct exhaustive analysis of cross-chain message validation, relayer logic, and state synchronization to prevent bridge drain attacks. Our audits cover LayerZero, Axelar, Wormhole, and CCIP implementations.

02
Consensus & Finality Discrepancy Analysis
We identify risks arising from differing finality times and consensus models between chains (e.g., Ethereum vs. Cosmos vs. Solana). This prevents double-spend and reorg attacks on your application logic.

Frequently Asked Questions

Our review follows a four-phase, white-box methodology tailored for cross-chain complexity. We start with a protocol architecture review to map all cross-chain message flows and asset bridges. This is followed by manual line-by-line auditing of core contracts, focusing on chain-specific vulnerabilities (e.g., gas optimization on Ethereum, reentrancy on EVM chains, program logic on Solana). We then execute dynamic testing using custom scripts to simulate cross-chain attacks like message replay, validator manipulation, and bridge draining. Finally, we provide a prioritized remediation report with exploit scenarios and proof-of-concept code.
