CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, and staking contracts with optimized gas costs.
- Security First: Every contract undergoes manual review and automated analysis with tools like
SlitherandMythX. - Full Lifecycle: From audit-ready development to mainnet deployment and upgrade management via proxies.
Deliver a secure, gas-efficient foundation for your protocol in 4-6 weeks, backed by a 99.9% uptime SLA for deployed contracts.
