Bridge Penetration Testing & Fuzzing

Active adversarial testing of live bridge infrastructure using automated fuzzing and manual exploit techniques to identify critical vulnerabilities before malicious actors.

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles and proven engineering practices to ensure reliability from day one.

  • Custom Logic: From ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols and DAO governance systems.
  • Security Audits: Every contract undergoes rigorous internal review and optional third-party audits from firms like CertiK or OpenZeppelin.
  • Gas Optimization: We write efficient code to minimize transaction costs for your users, often achieving 20-40% gas savings.

We don't just write code; we deliver secure, auditable financial infrastructure.

Our team specializes in Solidity 0.8+ and Vyper, leveraging battle-tested libraries like OpenZeppelin. We provide complete documentation, deployment scripts, and post-launch support to ensure your contracts operate flawlessly in a live environment.

PROVEN FRAMEWORK

Our Adversarial Testing Methodology

Our systematic approach simulates real-world attacks to uncover critical vulnerabilities before they can be exploited. We go beyond automated scanners with manual, adversarial thinking.

01

Threat Modeling & Architecture Review

We begin by deconstructing your bridge's architecture to identify high-value attack surfaces and potential trust assumptions. This maps out the attack vectors for targeted testing.

02

Manual Code Review & Logic Exploitation

Senior security engineers conduct line-by-line analysis of core smart contracts and off-chain components, hunting for business logic flaws, access control issues, and economic vulnerabilities.

04

Adversarial Scenario Simulation

We execute coordinated, multi-step attack scenarios—like oracle manipulation, liquidity draining, or governance takeovers—to test the system's resilience under active exploitation.

Smart Contract Development

Secure, gas-optimized smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts that form the foundation of your protocol. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and comprehensive audit trails.

  • Production-Ready Code: From ERC-20 tokens and ERC-721 NFTs to complex DeFi logic and DAO governance, we deliver audit-ready Solidity/Vyper.
  • Gas Optimization: Every line is written for minimum execution cost, reducing user fees and improving scalability.
  • Full Lifecycle Support: Development, testing (Hardhat/Foundry), deployment, and post-launch monitoring.

We translate your business logic into immutable, efficient code with a 99.9% uptime SLA for deployed contracts.

Technical & Commercial Questions

Bridge Penetration Testing FAQs

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

We employ a hybrid methodology combining automated fuzzing with expert-led manual review. Our process includes: 1) Architecture Review of the bridge's smart contracts, off-chain components, and governance model. 2) Automated Fuzzing using custom tools to generate millions of adversarial transaction sequences, targeting edge cases in asset locking, minting, and relayer logic. 3) Manual Exploit Development where our security engineers attempt to craft viable attacks based on identified vulnerabilities. 4) Economic & Game Theory Analysis to assess incentive misalignments and oracle manipulation risks. This approach has secured over $2B+ in cross-chain TVL across 30+ bridge projects.
