Chainlink-Backed USD Stablecoin Development
Budget: $30 – $250 USD
I’m creating a fully collateralised USD stablecoin on Ethereum and need a Solidity developer who can wire it to Chainlink Functions for continuous, on-chain proof of reserves. The token must always reflect a 1:1 ratio with the dollars held, so the contract has to fetch and verify live reserve data from my selected API provider (details shared after agreement).
Your core task is to craft the Chainlink integration contract that:
• Calls the external API through Chainlink Functions at set intervals
• Parses the returned reserve figure and compares it with the total supply
• Triggers pre-defined safeguards (e.g., mint/burn pause) if any mismatch is detected
Acceptance criteria
• Solidity code follows latest best practices and compiles cleanly under Hardhat
• Unit tests prove that oracle calls, data parsing, and safeguard logic work for edge cases
• Deployment scripts for Goerli and Mainnet with clear instructions
• Concise technical doc covering function flows, error handling, and how to swap in another API endpoint
I already have the API provider lined up, so there is no data-source research needed—just accurate, gas-efficient integration. If you’ve shipped Chainlink-enabled contracts before and can demonstrate bulletproof testing, I’d love to see your approach.
