CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From initial concept to mainnet deployment, we manage the full lifecycle with a focus on security and gas optimization.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi & DAOs: Automated market makers, staking pools, governance modules, and multi-sig wallets.
- Security First: Comprehensive unit testing, formal verification, and preparation for third-party audits by firms like CertiK or Quantstamp.
- Deliverable: Fully documented source code, deployment scripts, and a 2-week MVP timeline for standard implementations.
