CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by certified auditors to power your Web3 application.

We architect and deploy battle-tested smart contracts that form the immutable foundation of your protocol. Our development process is built on OpenZeppelin standards and follows formal verification principles to eliminate critical vulnerabilities before deployment.

From tokenomics to complex DeFi logic, we translate your business requirements into gas-optimized, upgradeable code.

  • Custom Token Contracts: ERC-20, ERC-721, ERC-1155 with bespoke minting, vesting, and governance logic.
  • DeFi & DEX Protocols: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming mechanisms.
  • Security-First Process: Every contract undergoes manual review and automated analysis with Slither/MythX before audit.
  • Full Deployment Suite: Includes verification on Etherscan, constructor argument management, and multi-signature wallet setup.
