Circle: cirBTC has been launched on Ethereum, providing 1:1 Bitcoin-backed collateral for institutional DeFi

According to official news, Circle announced that cirBTC has launched on Ethereum, providing 1:1 Bitcoin-backed collateral for the institutional DeFi market. cirBTC is supported by native BTC held in custody by Circle at a 1:1 ratio, offering on-chain reserve transparency through Chainlink reserve proofs.

cirBTC can be integrated into Circle Mint for minting and redemption, and it forms a unified operational model of dollar liquidity and Bitcoin collateral with USDC. In the future, cirBTC will also expand to multiple chains through Arc.
