Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built for security and speed:

  • Full audit-ready code using Solidity 0.8+ and OpenZeppelin standards.
  • Gas-optimized logic to minimize user transaction costs.
  • Comprehensive testing suite with 95%+ coverage before deployment.

Deliver a secure, functional MVP in as little as 2-3 weeks, not months.

We handle the entire lifecycle: from initial design and Hardhat/Foundry development to deployment on EVM chains (Ethereum, Polygon, Arbitrum) and Solana.

Typical deliverables include:

  • Token Contracts: Custom ERC-20, ERC-721, or ERC-1155 implementations.
  • DeFi Protocols: DEX pools, staking, lending/borrowing logic.
  • Governance Systems: DAO frameworks with voting and treasury management.
  • Full technical documentation and handover for your team.
