CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
- Security-First Development: Every contract undergoes peer review and automated analysis with tools like Slither and MythX before deployment.
- Gas Optimization: We reduce transaction costs by 15-40% through efficient coding patterns and storage optimization.
- Full Audit Support: We prepare detailed technical specifications and test suites to streamline third-party audits from firms like CertiK or Quantstamp.
From ERC-20/721 tokens and staking vaults to complex DeFi primitives, we deliver battle-tested code that powers your protocol's core logic.

Frequently Asked Questions
Get clear answers on how our zero-knowledge verification service works, from implementation to integration.
Standard ZK accreditation module deployment takes 2-3 weeks from kickoff to production. This includes custom circuit design, smart contract development, and frontend integration. Complex requirements like multi-chain verification or custom credential schemas can extend this to 4-6 weeks.
