StarkNet Smart Contract

Cairo or Solidity contracts with rigorous tests.

Custom smart contract on StarkNet (Cairo) or Ethereum (Solidity) with rigorous tests, testnet or mainnet deployment, optional frontend, and documentation. Typical use cases: tokens, NFTs, vesting, escrow, payments, voting, identity, supply chain proofs, and RWA.

Who it's for

  • Web3 startups with a defined product
  • Traditional companies with a real use case (not hype): supply chain, RWA, royalties
  • Crypto founders with runway and a mainnet target
  • Companies tokenizing real-world assets

What's included

  • Discovery and contract spec
  • Design and threat modeling
  • Implementation in Cairo (preferred) or Solidity
  • Unit, integration, and property-based tests
  • Testnet deploy (Sepolia or StarkNet testnet)
  • Minimal interaction frontend (optional)
  • On-chain verification on Etherscan or Voyager
  • Public documentation
  • Mainnet deploy (client pays gas)
  • Upgrade runbook when proxy pattern applies
