CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
Every contract undergoes a rigorous security process, including internal audits and integration with tools like Slither and MythX, before we recommend third-party verification.
- Standard Token Contracts:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance modules. - DeFi & DEX Logic: Automated Market Makers (AMMs), liquidity pools, staking, and yield aggregators.
- NFT Ecosystems: Generative collections, marketplaces with royalties, and dynamic metadata.
- Enterprise Logic: Custom business logic for supply chain, credentials, and asset tokenization.
We deliver audit-ready code within 2-4 weeks for an MVP, complete with comprehensive documentation and a deployment pipeline to testnet and mainnet.
