[1:1 Bitcoin Backing, Circle Explains cirBTC Segregated Custody and On-Chain Reserve Verification] Odaily Planet Daily News – Circle released an explanation of the cirBTC reserve mechanism, stating that each cirBTC is backed 1:1 by one native BTC and can be redeemed for native BTC at a 1:1 ratio. The corresponding BTC is held by Circle-affiliated entities and is custodied by Circle National Trust, which is regulated by the U.S. Office of the Comptroller of the Currency (OCC). The reserve assets are segregated from Circle's corporate assets and are solely used to protect the rights of cirBTC holders. cirBTC is currently live on Ethereum and will provide native support on the Arc mainnet after its launch, with plans to gradually expand to more blockchains. Circle also provides on-chain reserve verification through publicly disclosed BTC reserve addresses and the Chainlink Proof of Reserve mechanism, allowing market participants to compare the scale of reserve BTC with the circulating supply of cirBTC on supported chains.
