  • Work with frontend/backend teams to integrate smart contracts into full-stack dApps.
  • Optimize contracts for performance and scalability.

  • Deep understanding of Ethereum and/or Solana architecture and smart contract lifecycles.
  • Familiarity with token standards: ERC-20, ERC-721, ERC-1155, SPL tokens.
  • Hands-on experience with tools like Hardhat, Foundry, Truffle, Remix, or Anchor (for Solana).
  • Strong grasp of blockchain fundamentals: gas, transactions, nodes, consensus, etc.
  • Experience with unit testing smart contracts using Chai, Mocha, Waffle, or similar.
  • Version control using Git and collaborative coding (GitHub, GitLab).
  • Understanding of common smart contract vulnerabilities (e.g., reentrancy, integer overflow) and how to prevent them.

Nice to Have (Bonus Skills)

  • Experience working with Chainlink, The Graph, or other web3 integrations.
  • Prior experience with zero-knowledge proofs, zk-Rollups, or privacy-preserving contracts.
  • Experience with DeFi, NFT, or DAO-based projects.
  • Familiarity with wallet integrations (e.g., MetaMask, Phantom).
  • Contributions to open-source blockchain projects.
  • Understanding of L2s and bridges (Optimism, Arbitrum, zkSync).
