CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the secure backbone of your application. Our development process is built on audited patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.

Deploy with confidence using contracts that have passed rigorous internal and third-party audits.

Our development stack includes:

  • Solidity 0.8+ with OpenZeppelin libraries for security.
  • Foundry & Hardhat for comprehensive testing and deployment.
  • EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base).
  • Specialized protocols for DeFi (AMMs, lending), NFTs (ERC-721A), and DAOs.

Deliverables you receive:

  • Production-ready code with full test coverage (>95%).
  • Technical specification and architecture diagrams.
  • Deployment scripts and mainnet-ready packages.
  • Post-launch support and upgrade path planning.

We focus on security-first development to protect your assets and users, turning your protocol vision into a live, auditable system.
