CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.

We architect and deploy audited, gas-optimized smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built for security and speed, delivering a minimum viable product (MVP) in 2-3 weeks.

  • Security-First Development: Code built with Solidity 0.8+ and OpenZeppelin libraries, followed by third-party audits from firms like CertiK or Quantstamp.
  • Protocol Specialization: Custom ERC-20, ERC-721, ERC-1155, automated market makers (AMMs), staking pools, and multi-signature wallets.
  • Full Lifecycle Support: From architecture and testing to deployment, verification, and ongoing maintenance with 99.9% uptime SLAs.

We translate your business logic into immutable, efficient code that just works. Reduce your time-to-market and eliminate costly vulnerabilities.

Frequently Asked Questions

Get clear answers on timelines, costs, and technical specifics for building your custom ZK-optimized blockchain.

A standard deployment from architecture to mainnet launch takes 4-8 weeks. This includes 1-2 weeks for design and consensus modeling, 2-4 weeks for core development and integration with a ZK rollup stack (e.g., Polygon CDK, zkSync ZK Stack), and 1-2 weeks for testing, security audits, and deployment. Complex custom logic or novel cryptographic primitives can extend this timeline, which we scope during the initial discovery phase.
