CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for enterprise deployment.
From tokenomics to complex DeFi logic, we translate your requirements into gas-efficient, upgradeable, and secure on-chain systems.
Our development lifecycle includes:
- Comprehensive Security Review: Multi-stage audits using static analysis, fuzzing, and manual review.
- Gas Optimization: Code profiling to minimize transaction costs for your end-users.
- Upgrade Patterns: Implementation of
ProxyorDiamondstandards for seamless future upgrades. - Full Documentation & Testing: Complete
NatSpeccomments and a test suite with >95% coverage.
We specialize in high-stakes applications, delivering contracts for token launches (ERC-20/721/1155), custom DeFi protocols, and governance systems. Clients deploy to mainnet with confidence, typically achieving a 2-4 week MVP delivery cycle for core contract logic.

Frequently Asked Questions
Common questions from CTOs and technical founders about integrating real-world data into EVM prediction markets.
A standard integration, connecting 1-3 DePIN data sources (e.g., Helium, Hivemapper, DIMO) to an EVM prediction market, typically takes 2-4 weeks from kickoff to production deployment. Complex projects with custom oracle logic or multiple chains may extend to 6-8 weeks. We provide a detailed sprint plan in our initial technical assessment.
