Integrate automated on-chain audits of reserves

Asset Issuers

Issuers that mint on-chain tokens representing off-chain or cross-chain assets can leverage Chainlink Proof of Reserve at the smart contract level to help provide additional guarantees that they cannot mint more tokens than assets stored in reserves.

DeFi application developers

Smart contract application developers can integrate Chainlink Proof of Reserve as a circuit breaker to help ensure unexpected fractional reserve activity from issuers does not result in cascading user losses if unbacked tokens are minted.

DeFi Users

Users of smart contract applications can access Proof of Reserve data to gain transparency into their risk exposure and gain confidence in the backing of on-chain tokens collateralized by off-chain reserves, supporting the growth of the DeFi ecosystem.

Employ across various use cases

Digitized Assets

Help ensure stablecoins, CBDCs, and wrapped cross-chain assets are properly backed.

Circuit Breakers

Implement a failsafe in case something goes wrong with reserves.

New Financial Products

Unlock new on-chain-enabled financial instruments.

Cross-Chain Tokenization

Obtain collateralization data on any cross-chain asset across all blockchains.

How Chainlink Proof of Reserve works

Chainlink Proof of Reserve utilizes the largest decentralized collection of security-reviewed and Sybil-resistant node operators in the industry to acquire and verify reserve data. Unlike alternative methods, Chainlink nodes are independent and resilient to threats such as man-in-the-middle or denial-of-service attacks.

Bring end-to-end transparency to your on-chain and off-chain reserves

Industry leaders use Chainlink Proof of Reserve for its unmatched security, reliability, and compatibility across blockchains and existing enterprise infrastructure. Integrate Chainlink Proof of Reserve today to automate your auditing process and provide greater transparency for your users.
