CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Every contract undergoes manual code review and automated analysis with
Slither/MythXbefore deployment. - Gas Optimization: We write efficient code to reduce transaction costs by 15-40%, critical for high-frequency dApps.
- Full Audit Support: We prepare comprehensive documentation and test suites to streamline third-party audits from firms like CertiK or Quantstamp.
From a 2-week MVP prototype to a mainnet launch with multi-sig controls, we deliver contracts that are secure, scalable, and ready for users.

Frequently Asked Questions
Get clear answers on how we deliver secure, verifiable, and real-time ESG data feeds for your Web3 applications.
We implement a multi-layered verification process. Data is sourced from vetted, primary providers (e.g., Verra, Gold Standard registries, corporate sustainability reports) and cross-referenced. On-chain, data is secured via decentralized oracle networks with cryptographically signed attestations. Our oracles use zero-knowledge proofs (ZKPs) to allow data verification without exposing raw inputs, ensuring tamper-proof integrity for audits and compliance.
