BUILD
Custom Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
- Protocol Development: Custom
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi Systems: Automated Market Makers (AMMs), lending/borrowing protocols, staking contracts.
- Enterprise Logic: Multi-signature wallets, supply chain tracking, verifiable credentials.
- Security & Audit: Built with
OpenZeppelinlibraries and prepared for third-party audits from firms like CertiK or Quantstamp.
We deliver fully documented, tested, and deployable contracts in 2-4 weeks for an MVP, with a focus on long-term maintainability and upgradeability.
