DataFeeds and CCIP
summary
Workshop shows how to read Chainlink price oracles, compile an AggregatorV3 consumer, and call getLatestData as a gasless view using DataFeeds on Base testnet with scaled integer answers and on-chain heartbeat/threshold updates. It also demonstrates CCIP token transfer Optimism→Sepolia by funding a deployed router-backed contract, burning on source and minting on destination, inspecting the CCIP explorer, and confirming the transfer succeeds after finality — fast and end-to-end.
