CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment to mainnet.
From tokenization to complex DeFi logic, we deliver contracts that are gas-optimized, upgradeable, and secure by design.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance modules. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming contracts.
- Enterprise Logic: Multi-signature wallets, access control, and compliant asset issuance frameworks.
- Delivery: Full test coverage, deployment scripts, and comprehensive documentation included.
