Circle has introduced cirBTC, a wrapped Bitcoin token backed 1:1 by native Bitcoin reserves. The token is designed to provide institutional users with on-chain-verifiable BTC exposure, enabling lending, borrowing, and participation in decentralized finance protocols.

2. Integration with Circle Ecosystem

cirBTC will launch on Ethereum mainnet and on Arc, Circle’s stablecoin-focused blockchain, with seamless integration into USDC and the Circle Mint issuance platform. This unified infrastructure aims to leverage Circle’s existing full-stack flexibility to attract institutions.
