overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts that form the operational backbone of your Web3 product. Our development process is built on security-first principles and proven patterns, ensuring your core logic is robust and future-proof.

  • Full-Stack Development: From ERC-20 tokens to complex DeFi protocols, NFT marketplaces, and cross-chain bridges.
  • Security & Audits: Code is developed with OpenZeppelin libraries and undergoes rigorous internal review before third-party audits.
  • Gas Optimization: Every contract is optimized for minimum execution cost, a critical factor for user adoption and scalability.

We deliver battle-tested contracts with clear documentation, enabling your team to iterate and scale with confidence.

Frequently Asked Questions

Get clear answers on our process, timelines, and technical approach for building custom zero-knowledge circuit libraries.

We deliver a production-ready, audited ZK circuit library in 4-8 weeks for most projects. The timeline depends on the complexity of the proving system (e.g., Groth16, Plonk, Halo2), the number of custom constraints, and the required integration depth. A standard library with 5-10 core operations typically takes 4-5 weeks from spec to audit-ready code.
