Building Ethereum Workflows with Streamr
summary
Shows a working integration of Streamr, Chainlink and Ethereum where a Solidity contract is deployed on Ropsten testnet, called from a browser module and its events are decoded and piped to Streamr streams and modules. Demonstrates a live button that triggers transactions, real-time event decoding (indexed fields show hashes), and a marketplace flow for car telemetry used in a pilot with automotive partners; system works end‑to‑end but shows occasional latency and missing events.
