CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the secure backbone of your protocol. Our development process is built on audited security patterns and gas-optimized code to ensure reliability and cost-efficiency from day one.
We deliver battle-tested contracts, not experimental code.
Our full-cycle development includes:
- Architecture & Design: Technical specification using industry standards like
ERC-20,ERC-721, and custom logic. - Implementation: Development in
Solidity 0.8+orRust(for Solana), leveragingOpenZeppelinlibraries. - Security: Multi-stage review, automated testing with
Hardhat/Foundry, and preparation for third-party audits. - Deployment & Integration: Mainnet deployment with comprehensive monitoring setup.
Typical deliverables for a startup MVP include a token contract, staking mechanism, and core protocol logic, delivered in 2-4 weeks. We focus on creating modular, upgradeable systems that scale with your product roadmap.
