CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from token standards to complex DeFi logic.
From a 2-week MVP to a multi-chain protocol, we build the foundational logic your application depends on.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626Vaults with tailored minting, burning, and governance logic. - DeFi & dApps: Automated Market Makers (AMMs), staking pools, lending protocols, and bespoke business logic.
- Security & Audit-Ready Code: Every contract undergoes internal review against common vulnerabilities (reentrancy, overflow) and is structured for seamless third-party audit integration.
