According to official sources, Circle announced that cirBTC has been launched on Ethereum, providing 1:1 bitcoin-backed collateral to the institutional DeFi market. cirBTC is supported by native BTC hosted by Circle in a 1:1 ratio, providing on-chain reserve transparency through Chainlink Reserve Proof. CirBTC can be integrated into CircleMint to achieve foundry redemption, and form a unified operating model with USDC for US dollar liquidity and Bitcoin collateral. In the future, cirBTC will also be expanded to multiple chains through Arc.
