CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic.
- Full Lifecycle Development: From specification and
Solidity/Rustcoding to deployment and verification on Etherscan/Solscan. - Gas Optimization: We write contracts that minimize transaction costs, a critical factor for user adoption.
- Integration Ready: Contracts are built with clear interfaces for easy frontend and backend integration.
- Comprehensive Testing: Unit, integration, and scenario testing using
HardhatorAnchorto ensure reliability.
Deploy a secure, audited smart contract suite in as little as 2-3 weeks, accelerating your product's time-to-market while mitigating critical security risks.

Frequently Asked Questions
Get clear, specific answers about our development process, security, and support for your payment infrastructure.
A standard deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your chosen blockchains (e.g., Ethereum, Polygon, Arbitrum), and frontend/backend setup. Complex requirements like custom governance or novel bridge integrations can extend this to 6-8 weeks. We provide a detailed project plan within the first 48 hours of engagement.
