Blockchain Developer – On-Chain Contribution Certificates, NFT/SBT

Remote, USA Full-time Posted 2026-06-13

• Job Description:

  • Develop the MVP for an on-chain certificate system for Roxonn contributors:
  • Design and implement a smart contract (e.g., ERC1155, custom SBT, or non-transferable ERC721) on the XDC Network for minting and managing these certificates.
  • Define and structure the metadata for certificates (e.g., contributor ID, achievement details, project link, date, skills demonstrated).
  • Consider storage solutions like IPFS/Arweave for off-chain metadata parts.
  • Develop backend logic (Node.js/TypeScript) to trigger the minting of certificates based on defined criteria (for MVP, this might be a manual admin trigger for verified achievements).
  • Implement frontend components (React/TypeScript) to display earned certificates on a contributor's Roxonn profile.
  • Ensure the system is secure and gas-efficient.
  • Requirements:
  • Strong experience in Smart Contract development with Solidity (preferably for XDC/EVM-compatible chains).
  • Experience with NFT/SBT standards (ERC721, ERC1155, or emerging SBT patterns).
  • Backend development experience (Node.js/TypeScript) for Web3 integrations.
  • Frontend development experience (React/TypeScript) with Web3 libraries (e.g., ethers.js, web3.js).
  • Understanding of metadata standards and storage solutions (e.g., IPFS, Arweave).
  • Familiarity with blockchain security best practices.
  • Knowledge of the XDC Network ecosystem is a plus.
