Cross-Chain Bridge Security Audit

Independent, in-depth security assessment of your cross-chain bridge smart contracts. We focus on message validation, asset custody, and signature verification to mitigate risks like those seen in major bridge exploits.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your protocol or application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.

  • End-to-End Development: From initial design and ERC-20/721/1155 tokenomics to complex DeFi logic and governance systems.
  • Security-First Approach: Every contract undergoes rigorous internal audits and is prepared for third-party review by firms like CertiK or Quantstamp.
  • Production Focus: We deliver audited, verified, and deployable code with comprehensive documentation for your team.

We don't just write code; we deliver the secure, battle-tested infrastructure your business runs on.

Our engineers specialize in:

  • DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
  • NFT Ecosystems: Generative collections, marketplaces with royalties, and dynamic utility contracts.
  • Enterprise Logic: Custom business logic for tokenization, supply chain, and identity verification.

Typical Deliverables:

  • Fully audited and commented source code in Solidity or Vyper.
  • Deployment scripts and configuration for Ethereum, Polygon, Arbitrum, or other EVM chains.
  • Technical specification document and user/admin guides.
  • Post-deployment support and upgrade path planning using transparent proxies.

COMPREHENSIVE ANALYSIS

What Our Cross-Chain Bridge Security Audit Covers

Our security audit is a deep, systematic review of your bridge's architecture and code. We deliver a prioritized report with actionable fixes, not just a list of vulnerabilities.

01

Smart Contract Security

In-depth analysis of core bridge logic, token wrapping, and governance contracts. We test for reentrancy, access control flaws, and economic logic errors using both static and dynamic analysis tools.

EXPLORE
02

Cryptographic Verification

Rigorous review of all signature schemes, hash functions, and zero-knowledge proofs. We ensure the integrity of message passing, validator set updates, and fraud-proof mechanisms.

EXPLORE
03

Economic & Incentive Analysis

Stress-testing of the bridge's economic security. We model attack vectors like validator collusion, liquidity manipulation, and MEV extraction to identify systemic risks.

EXPLORE
04

Relayer & Oracle Security

Assessment of off-chain components' trust assumptions. We audit data availability, liveness guarantees, slashing conditions, and failure modes of external data feeds.

EXPLORE
05

Upgradeability & Governance

Review of timelocks, multi-sig configurations, and emergency pause mechanisms. We ensure upgrade paths are secure and governance processes resist takeover.

EXPLORE
06

Cross-Chain Consistency

Verification of state synchronization across all supported chains (EVM, Cosmos, Solana, etc.). We check for consensus mismatches, double-spend risks, and chain reorganization handling.

EXPERTISE YOU CAN TRUST

Why Choose Chainscore for Your Bridge Audit

Bridge security is non-negotiable. We deliver deep technical audits that go beyond automated checks, combining protocol expertise with adversarial thinking to secure your cross-chain infrastructure.

01

Protocol-Specific Expertise

Our auditors have hands-on experience with the core protocols your bridge uses: Wormhole, LayerZero, Axelar, and Hyperlane. We understand the unique attack vectors and security models of each.

EXPLORE
02

Adversarial Security Review

We simulate real-world attacks, testing for critical vulnerabilities like signature replay, oracle manipulation, and economic exploits that automated tools miss. Every finding includes a detailed Proof-of-Concept.

03

Comprehensive Risk Framework

We assess your bridge against a proprietary 50+ point checklist covering smart contracts, relayer logic, economic incentives, and operational security, delivering a prioritized risk matrix.

04

Clear, Actionable Reporting

Receive a detailed technical report with severity ratings, exploit scenarios, and concrete remediation steps—not just a list of issues. We provide follow-up verification to ensure fixes are correctly implemented.

05

Proven Track Record

Our team has secured over $5B+ in cross-chain TVE (Total Value Enabled) across 30+ bridge audits for leading DeFi protocols and infrastructure providers.

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts.

We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our development process is built on audited code patterns and rigorous testing to mitigate risk.

  • From Concept to Deployment: Full lifecycle support from specification and Solidity/Rust development to deployment and verification.
  • Security-First: Contracts are built with OpenZeppelin libraries and undergo internal audits before third-party review.
  • Protocol-Specific Logic: Expertise in ERC-20, ERC-721, ERC-1155, staking mechanisms, governance modules, and custom DeFi primitives.

Deliver a market-ready, secure contract suite in as little as 2-4 weeks, accelerating your product's time-to-market.

Why Specialization Matters

Chainscore Bridge Audit vs. Generic Smart Contract Review

Generic audits often miss critical cross-chain attack vectors. Our dedicated bridge security service provides comprehensive coverage for the unique risks of interoperability protocols.

Frequently Asked Questions on Bridge Audits

Get clear answers on our methodology, timeline, and deliverables for securing your cross-chain infrastructure.

We employ a multi-layered methodology combining automated analysis with deep manual review. This includes: 1) Architectural Risk Analysis of the entire message flow and trust assumptions. 2) Smart Contract Security Review using static analysis (Slither), fuzzing (Echidna), and manual line-by-line inspection for logic flaws. 3) Economic & Incentive Modeling to stress-test the system's cryptoeconomic security under adversarial conditions. 4) Operational Security Review of upgrade mechanisms, admin key management, and emergency procedures. Our reports detail findings with clear severity levels (Critical, High, Medium, Low), exploit scenarios, and specific, actionable remediation steps.
