cirBTC: A Clearer Reserve Standard for Wrapped BTC

See how proof of reserves for wrapped assets works for cirBTC, live on Ethereum with Arc support coming soon, with Chainlink reserve data and verification.

  • cirBTC introduces a new standard for wrapped Bitcoin (WBTC) by emphasizing 1:1 BTC backing, segregated custody, and verifiable on-chain reserve data.
  • The system utilizes Chainlink Proof of Reserve to independently verify reserve information and publish it on-chain, allowing for continuous monitoring by protocols and risk systems.
  • cirBTC is currently live on Ethereum and planned for Arc mainnet, aiming to provide institutions with a transparent and reliable way to assess the collateral backing of wrapped Bitcoin.
