CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your token, DeFi, or NFT project.
From token launches to complex DeFi logic, we deliver contracts you can trust to handle real value.
- Standard Token Contracts: Custom
ERC-20,ERC-721, andERC-1155implementations with minting, vesting, and governance modules. - DeFi & DEX Protocols: Automated Market Makers (AMMs), liquidity pools, staking systems, and yield aggregators.
- Security First: Every contract undergoes static analysis, fuzz testing, and audit review before mainnet deployment.
- Full Ownership & Documentation: You receive all source code, technical specs, and deployment scripts for complete autonomy.
