CBTC now integrates Chainlink Proof of Reserve and Chainlink Data Streams, providing continuous reserve verification and low-latency BTC pricing for applications across the Canton ecosystem.
What This Enables
For Bitcoin-backed assets to function in regulated financial workflows, counterparties need to verify backing and pricing continuously. Manual disclosures and periodic attestations are insufficient for collateralized lending, margining, and structured products where asset backing must be confirmed in real time.
CBTC now addresses both requirements through standardized Chainlink infrastructure:
Chainlink Proof of Reserve provides on-chain verification that every CBTC is backed 1:1 by Bitcoin held in the Attestor Network's custody. Applications, counterparties, and developers can independently verify backing data at any time without relying on off-chain attestations.
Chainlink Data Streams delivers low-latency BTC pricing for CBTC-based applications on Canton. This enables accurate mark-to-market calculations, liquidation logic, and automated settlement across institutional workflows.
Why This Matters for Canton Developers
With Proof of Reserve and Data Streams live, developers building on Canton can integrate CBTC as collateral without implementing custom oracle solutions. The standardized data infrastructure handles pricing and reserve verification, reducing integration complexity.
Supported use cases include:
Lending and borrowing. CBTC as verifiable collateral with continuous backing confirmation.
Swap pools. Real-time BTC pricing for accurate execution.
Structured products. Automated settlement with reliable mark-to-market data.
Options and derivatives. On-chain pricing feeds for institutional-grade risk management.
Canton-native applications including Thetanuts Finance (on-chain options) and Kairo (decentralized exchange) can integrate CBTC using these shared data primitives as they build new products and markets.
This integration reflects a broader effort to establish common verification and pricing standards for Bitcoin-backed assets on Canton. As more applications adopt CBTC and other Canton-native assets, shared data infrastructure improves transparency and risk management across the ecosystem while reducing the overhead for each individual integration.
BitSafe continues to build alongside teams deploying financial applications on Canton. Standardized Chainlink infrastructure is one component of making CBTC a reliable building block for the ecosystem.
