CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

  • Full Lifecycle Delivery: From initial design and Solidity/Rust development to deployment, verification, and monitoring.
  • Proven Security: Built with OpenZeppelin libraries and patterns, prepared for third-party audits by firms like Trail of Bits or CertiK.
  • Multi-Chain Expertise: Deployments on Ethereum, Polygon, Arbitrum, Solana, and other EVM/L1 networks.

We deliver contracts that are secure by design, reducing your time-to-audit and mitigating costly vulnerabilities before deployment.

Our contracts are built for real-world use:

  • Upgradeability: Implement Proxy patterns for seamless, secure future upgrades.
  • Gas Efficiency: Optimized logic to minimize transaction costs for your users.
  • Comprehensive Testing: Unit, integration, and scenario testing with Hardhat or Foundry to ensure reliability.

Quantum-Resistant Wallet FAQs

Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating quantum-resistant wallet architecture.

A standard quantum-resistant wallet core (key generation, transaction signing, backup/restore) takes 3-5 weeks to develop, audit, and deploy to testnet. Full integration with a custom front-end and multi-chain support typically extends the project to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
