CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect, develop, and deploy custom smart contracts that form the secure backbone of your dApp. Our engineers specialize in Solidity, Rust (Solana), and Move (Aptos/Sui), implementing battle-tested patterns from OpenZeppelin and Sealevel.
From tokenization to complex DeFi logic, we deliver contracts that are secure by design and ready for mainnet.
- Security-First Process: Multi-stage audits, formal verification with tools like
Slither/Mythril, and comprehensive unit/integration testing. - Gas Optimization: We write efficient code to reduce user transaction costs by up to 40%.
- Full Lifecycle Support: Development, deployment, verification on Etherscan/Solscan, and ongoing upgrade management via transparent proxies.

Frequently Asked Questions
Get clear answers on timelines, security, and implementation for your utility token wallet system.
A standard deployment for a utility provider takes 3-5 weeks. This includes smart contract development, frontend integration, and security audits. Complex features like multi-chain support or advanced gas sponsorship models can extend this to 6-8 weeks. We provide a detailed project plan within the first week of engagement.
