Job Description
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. Benefits: Apply tot his job
