overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific use case. Our development process includes:

  • Formal specification and architectural review.
  • Gas optimization for predictable transaction costs.
  • Comprehensive testing with 95%+ coverage using Hardhat or Foundry.
  • Integration with OpenZeppelin libraries and established security patterns.

We deliver a fully audited, deployable contract suite in 2-4 weeks, from concept to mainnet readiness.

Our team specializes in:

  • DeFi Protocols: DEXs, lending/borrowing, yield aggregators, and liquidity management.
  • NFT Ecosystems: ERC-721A, ERC-1155 marketplaces with advanced minting mechanics.
  • Enterprise & DAOs: Custom governance, multi-sig wallets, and asset tokenization (ERC-20, ERC-1400).

Frequently Asked Questions

Get clear answers on development timelines, security, costs, and ongoing support for your custom private data marketplace.

A standard MVP with core features (data listing, access control, encrypted storage, payment channels) takes 4-6 weeks. Complex deployments with custom zero-knowledge proofs, multi-chain settlement, or advanced governance can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial discovery phase.
