+## Exchange Rate Report Schema
+
+[Chainlink Exchange Rate Data Streams](./report-schema-v7) provide tamper-proof access to the exchange rate of tokenized assets, delivered over the low latency, high frequency Chainlink Data Streams infrastructure. Exchange rates typically read directly from onchain smart contracts. These exchange rates generally have a single calculating agent: the issuing protocol.
+
+While the Data Streams architecture is designed to deliver updates at least once per second, the exchange rate itself is often updated only once per day by the data source, in line with standard market practices. Data Streams ensures that any Exchange Rate update, whenever it occurs, is captured and made available immediately and at low latency, allowing seamless integration into onchain applications alongside other real-time data streams.
+
+The v7 schema is designed specifically for Exchange Rate feeds and reports a single value: the exchange rate (`exchangeRate`).

 ## Real World Asset (RWA) Report Schema
 
 [Chainlink RWA Data Streams](./report-schema-v8) provide fresh, reliable, and accurate financial market data for real-world assets, enabling DeFi users to gain onchain exposure to physical assets. Each report includes a staleness measure (`lastUpdateTimestamp`), consensus median price (`midPrice`) and market status (`marketStatus`).
