CBTC Data & Price Feeds

Proof of Reserve

CBTC is backed 1:1 by Bitcoin, and that backing is verifiable on-chain through the Chainlink Proof of Reserve feed. The feed reports the reserves held against circulating CBTC and can be used for backing verification, monitoring, and risk checks.

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, which provides Kaiko-signed price quotes that can be verified and consumed within Canton workflows: https://docs.kaiko.com/on-chain/kaiko-data/kaiko-reference-rates/data-on-ramp/canton-pull-oracle
• Off chain, through Kaiko’s REST API: https://docs.kaiko.com/rest-api/analytics-solutions/kaiko-fair-market-value/established-assets
  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.
