overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy audit-ready smart contracts for DeFi, NFTs, and enterprise applications. Our team delivers custom logic for tokens (ERC-20, ERC-721), automated market makers, staking systems, and governance modules, ensuring gas efficiency and security-first design from day one.

Reduce your time-to-market from months to weeks with our battle-tested development framework.

  • Comprehensive Audits: Code is structured for seamless review by top firms like OpenZeppelin and CertiK.
  • Upgradeable Architecture: Implement Transparent Proxy or UUPS patterns for future-proof, non-breaking upgrades.
  • Gas Optimization: Achieve 20-40% lower transaction costs through advanced optimization techniques.
  • Full Test Suite: Deploy with confidence using extensive unit and integration tests covering >95% code coverage.

PROVEN FRAMEWORK

Our Adversarial Testing Methodology

We simulate sophisticated attacks to uncover critical vulnerabilities in your bridge's architecture before they are exploited. Our methodology is trusted by protocols securing billions in cross-chain value.

01

Architecture & Design Review

We analyze your bridge's core components—relayers, validators, and message-passing layers—against known attack vectors like race conditions, reentrancy, and governance exploits.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We deliver audit-ready code for ERC-20, ERC-721, and custom protocols, ensuring your tokenomics and business logic are flawlessly executed on-chain. Our contracts are built with OpenZeppelin standards and security-first patterns from day one.

  • Token Systems: Custom fungible/non-fungible tokens with advanced features like vesting, staking, and governance.
  • DeFi Protocols: Automated market makers (AMMs), lending pools, and yield aggregators with gas-optimized math.
  • Enterprise Logic: Multi-signature wallets, asset bridges, and verifiable supply chain tracking.

From initial architecture to mainnet deployment, we provide a complete development lifecycle with 99.9% uptime SLAs and post-launch support. Reduce your time-to-market from months to as little as 2 weeks for an MVP.

Heterogeneous Bridge Security Audit FAQs

Get answers to the most common questions about our specialized penetration testing service for cross-chain bridges.

We employ a four-phase methodology tailored for cross-chain systems: 1) Architecture Review of all smart contracts, relayers, and off-chain components. 2) Dynamic Testing simulating attacks like reorgs, validator failures, and message forgery. 3) Economic & Game Theory Analysis to model incentives for relayers and validators. 4) Final Verification of fixes. Our process is based on the OWASP Top 10 for Blockchain and internal checklists refined from securing over $2B in bridged assets.
