SECURE FOUNDATIONS

Custom Smart Contract Development

Production-grade smart contracts built for security, scalability, and seamless integration.

We architect and deploy audit-ready smart contracts that form the secure, immutable core of your Web3 application. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring gas efficiency and protection against common vulnerabilities from day one.

From tokenization to complex DeFi logic, we deliver contracts that are built to perform at scale.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like vesting, minting controls, and governance hooks.
  • DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
  • Security First: Every contract undergoes internal review and is structured for seamless integration with leading audit firms like CertiK or Quantstamp.
  • Full Lifecycle Support: Development, testing on Hardhat/Foundry, deployment, and post-launch maintenance.

EXPERTISE YOU CAN TRUST

Why Choose Our Specialized ZK Bridge Audit

Secure your cross-chain value transfer with audits built by engineers who understand the mathematical and cryptographic complexities of zero-knowledge proofs.

01

ZK Circuit & Prover Expertise

Our team includes cryptographers who audit the core Plonk, Groth16, and STARK circuits. We identify vulnerabilities in constraint systems, proof generation, and verification logic that generic auditors miss.

Expert Insights

ZK-Rollup Bridge Security Audit FAQs

Get answers to the most common questions about our rigorous security audit process for ZK-Rollup bridges, designed to give CTOs and technical founders confidence in their critical infrastructure.

We employ a five-phase methodology tailored for ZK-Rollup complexity: 1) Architecture Review of the bridge's state transition logic and fraud/validity proof system. 2) Smart Contract Audit of on-chain verifiers, relayers, and asset management contracts using static/dynamic analysis and manual review. 3) ZK Circuit Audit focusing on the prover/verifier implementation, constraint system correctness, and cryptographic soundness. 4) Integration & Economic Security Review of cross-chain messaging, sequencer assumptions, and incentive models. 5) Final Verification & Report with actionable findings and remediation guidance. This process has secured over $2B+ in bridged assets across 30+ projects.
