EVM Smart Contract Fuzzing Suite

Comprehensive, automated fuzzing for Ethereum and EVM-compatible chains, targeting reentrancy, integer overflows, and state corruption to uncover vulnerabilities before mainnet deployment.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security, gas efficiency, and seamless integration with your existing stack.

  • Security-First Development: Code built on Solidity 0.8+ with OpenZeppelin libraries, followed by third-party audits from firms like CertiK or Quantstamp.
  • Protocol-Specific Expertise: ERC-20, ERC-721, ERC-1155, ERC-4626, and custom logic for DeFi, NFTs, DAOs, and RWA tokenization.
  • Full Lifecycle Support: From initial design and testing to deployment, verification, and ongoing maintenance on EVM-compatible chains.

Deliver a market-ready, secure contract suite in 2-4 weeks, backed by formal verification and comprehensive documentation.

We translate your business logic into immutable, trustless code. Every contract includes gas optimization reports, a full test suite with >95% coverage, and clear technical specs for your team.

Business Outcomes: Secure Deployment, Faster Time-to-Market

Our EVM Smart Contract Fuzzing Suite delivers measurable results for technical leaders. We focus on the metrics that matter for production readiness and team velocity.

01

Proactive Vulnerability Discovery

We identify critical security flaws—reentrancy, logic errors, gas issues—before deployment. Our fuzzing uncovers edge cases unit tests miss, reducing post-launch patches by 90%.

CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from tokens to complex DeFi logic.

We architect and deploy production-ready smart contracts that form the immutable foundation of your Web3 application. Our development process is built on security-first principles and proven patterns, ensuring your core logic is robust and resilient.

  • Token Standards: Custom ERC-20, ERC-721, ERC-1155, and ERC-4626 vaults with tailored minting, burning, and governance logic.
  • DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
  • Enterprise Logic: Custom business logic for supply chain, identity, and asset tokenization with gas-optimized execution.

Every contract undergoes rigorous security audits using both automated tools and manual review by our senior Solidity engineers before deployment to mainnet.

We deliver fully documented, upgradeable contracts with a clear handoff, enabling your team to own and iterate on the codebase. Typical delivery for a core protocol MVP is 2-4 weeks.
