CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built for security-first deployment, ensuring your assets and users are protected from day one.

  • Full Lifecycle Development: From initial design and Solidity/Rust coding to deployment and ongoing maintenance.
  • Security by Default: All contracts undergo internal audits and are built with OpenZeppelin standards. We prepare for formal audits with CertiK or Quantstamp.
  • Gas Optimization: We write for efficiency, reducing transaction costs by up to 40% through optimized storage and logic patterns.

We deliver battle-tested contracts that execute exactly as intended, eliminating costly exploits and failed transactions.

Our focus is on reliability and correctness. We implement:

  • Upgradeable Patterns: Using transparent proxies (ERC-1967) for seamless, secure updates.
  • Compliance Ready: Integrate ERC-20, ERC-721, and ERC-1155 with modular features for regulatory requirements.
  • Real-World Testing: Rigorous simulation against mainnet forks to catch edge cases before launch.

Governance SDK Development FAQs

Get clear answers on our process, timeline, and security for building custom governance SDKs that integrate seamlessly with your protocol.

A standard Governance SDK for a single blockchain (e.g., EVM) with core voting, proposal, and delegation features takes 3-5 weeks from kickoff to production-ready delivery. Complex multi-chain integrations or advanced features like quadratic voting can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the discovery phase.
