CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.
Deliver a battle-tested, secure foundation for your product in as little as 2-4 weeks.
Our typical engagement delivers:
- End-to-end development from architecture to mainnet deployment.
- Contracts built with Solidity 0.8+ and OpenZeppelin standards.
- Comprehensive testing suites including unit, integration, and scenario tests.
- Gas optimization reports to minimize user transaction costs.
We specialize in complex DeFi primitives, NFT ecosystems (ERC-721A, ERC-1155), and cross-chain logic. Every contract undergoes peer review and is prepared for third-party audits from firms like CertiK or Quantstamp.

Frequently Asked Questions
Get clear answers on development timelines, security, costs, and ongoing support for your enterprise-grade credentialing platform.
A standard enterprise credentialing platform takes 6-10 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design, 3-4 weeks for core smart contract and backend development, 1-2 weeks for integration testing and security audits, and 1-2 weeks for deployment and client onboarding. Complex integrations (e.g., with legacy HR systems) or custom compliance features can extend the timeline, which we scope and communicate upfront.
