CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
We architect and deploy custom smart contracts that power your core business logic. Our development process is built on Solidity 0.8+ with OpenZeppelin security patterns, ensuring robust foundations for tokens (ERC-20, ERC-721), DeFi protocols, DAOs, and complex multi-contract systems.
We deliver production-ready code with comprehensive test coverage, gas optimization reports, and a clear deployment roadmap—typically within 2-4 weeks for an MVP.
- Security-First Development: Every line is written with security as the priority, followed by formal verification and third-party audit preparation.
- Full-Stack Integration: Contracts are designed to work seamlessly with your front-end, indexers, and backend services.
- Ongoing Maintenance: We provide upgradeability patterns, monitoring, and incident response support post-launch.

Frequently Asked Questions
Common questions from CTOs and product leads about integrating blockchain payments into physical retail hardware.
Standard integrations take 2-4 weeks from kickoff to pilot launch. This includes hardware provisioning, SDK integration, smart contract deployment, and on-site testing. Complex multi-chain or custom loyalty program features can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
