The feed reports the reserves held against circulating CBTC and can be used for backing verification, monitoring, and risk checks. * Chainlink CBTC PoR / NAV feed: ### Price data Kaiko provides a CBTC price feed built on Temple market data (the CBTC-USDCx pair). The pricing is served through Kaiko’s Fair Market Value endpoints available: * On chain, through Kaiko’s [Pull Oracle](https://docs.kaiko.com/on-chain/kaiko-data/kaiko-reference-rates/data-on-ramp/canton-pull-oracle), which provides Kaiko-signed price quotes that can be verified and consumed within Canton workflows: * Off chain, through Kaiko’s REST API: \ To get access to the Kaiko endpoint, reach out to the BitSafe team and we’ll make an introduction to Kaiko directly. ### BTC/USD as a reference price Since CBTC is redeemable 1:1 for Bitcoin, a BTC/USD price feed remains a valid reference for integrations that don't yet need a dedicated CBTC feed. See the existing guide on integrating a BTC/USD price feed for CBTC. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.bitsafe.finance/product-suite/cbtc/cbtc-data-and-price-feeds.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
