CommodityOracle

CommodityOracle is a decentralized oracle system that provides commodity and RWA price data on-chain.
It uses signature-based updates to securely push off-chain prices to smart contracts, and a consumer contract to easily read those prices.

What this project does

Fetches commodity prices off-chain
Verifies them on-chain using cryptographic signatures
Stores latest prices securely
Allows other contracts to read prices easily

Progress During Hackathon Designed the overall Commodities / RWA Oracle architecture Implemented the CommodityOracle smart contract with: Signature-based price updates Replay protection Timestamp (staleness) validation Bulk price update support Built the CommodityConsumer contract for: Easy price querying Single and bulk asset reads Convenience functions (e.g. Natural Gas) Integrated off-chain price data format aligned with real commodity APIs Deployed both contracts on Sepolia (Mantle) testnet Added support for 100+ assets including commodities, stocks, indices, ETFs, and FX Created an interactive table listing all supported assets and their feed IDs Documented usage examples for: Reading prices Updating prices securely Designed a Commodities Oracle logo and architecture diagrams
