overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Custom Logic: From
ERC-20tokens andERC-721NFTs to complex DeFi protocols and DAO governance systems. - Security First: Built with
OpenZeppelinstandards, tested withFoundry/Hardhat, and audited by industry-leading firms. - Gas Optimization: Every contract is optimized for minimum gas consumption, reducing user costs by up to 40%.
- Full Lifecycle: We handle deployment, upgradeability planning (using proxies like
UUPS), and ongoing maintenance.
Deliver a secure, audited, and gas-optimized smart contract suite in as little as 3 weeks, from spec to mainnet.

Frequently Asked Questions
Get clear answers on our process, security, and delivery for building your private cross-chain token system.
Our engagement follows a structured 4-phase process: 1) Discovery & Design (1-2 weeks): We analyze your use case, threat model, and chain requirements to architect the protocol. 2) Core Development (3-6 weeks): We build the core cryptographic circuits (zk-SNARKs/zk-STARKs), smart contracts, and relayer infrastructure. 3) Security & Audit (2-3 weeks): The system undergoes internal review and a formal audit by a top-tier firm like Quantstamp or Trail of Bits. 4) Deployment & Integration (1-2 weeks): We deploy the contracts, set up the relayers, and integrate with your front-end. We provide a fixed-price proposal after the discovery phase.
