Prevent systemic failures and contagion

Prove onchain and offchain collateral reserves to help mitigate risk and protect users from unexpected fractional reserve activity.

Integrate transparent verifications of reserve assets

Asset issuers

Issuers minting onchain tokens representing offchain or cross-chain assets can integrate Chainlink Proof of Reserve to help provide additional guarantees that they cannot mint more tokens than assets stored in reserves.

DeFi application developers

Smart contract 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

Chainlink Proof of Reserve helps DeFi users get transparency into their risk exposure, increasing confidence in the backing of onchain tokens collateralized by offchain reserves.

Employ Chainlink Proof of Reserve across various use cases

Digitized Assets

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

Circuit Breakers

Implement a failsafe to prevent undercollateralization.

New Financial Products

Create fully-transparent onchain financial instruments.

Cross-Chain Tokenization

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

What is proof of reserves?

Within the blockchain space, proof of reserves is commonly known as an independent verification that enables centralized exchanges to publicly report the value of their reserves and prove their solvency. Because centralized third parties typically conduct this reporting, they can be lengthy, opaque, and time-consuming manual processes.

Chainlink Proof of Reserve (PoR) builds upon this concept to provide a customized solution for Web3. It enables seamless, decentralized, and autonomous proof of reserves reporting by verifying collateral amounts and posting that data onchain. With Chainlink PoR, users have more transparency, updates in real-time, and stronger guarantees around the proof of reserves’ accuracy.
