Circle introduced a streamlined workflow that allows eligible institutions to deposit Bitcoin, convert it into wrapped cirBTC collateral, and borrow USDC through a Morpho lending market in a single process. The service launched on Arc and Ethereum on Sept. 21, aiming to reduce the number of platforms treasury teams must use to obtain dollar liquidity without selling Bitcoin. Access remains restricted to qualifying institutions, excludes New York-based clients, and operates under jurisdiction-specific eligibility rules. Deposited Bitcoin is transformed into cirBTC, a tokenized claim backed by native Bitcoin, which serves as collateral in a customer-controlled wallet. Borrowed USDC settles into the user's Circle Mint balance. While Circle coordinates the interface, borrowing parameters such as costs, collateral limits, liquidation thresholds, and available liquidity are determined by the selected Morpho market. Each market combines loan asset, collateral type, oracle source, interest-rate model, and liquidation loan-to-value settings. The streamlined process does not eliminate the need for treasury teams to monitor collateral values, utilization rates, and borrowing costs. Positions can become liquidatable even when the underlying Bitcoin remains unsold, because cirBTC is held within the lending market. A recent snapshot of the Arc market indicated an 86% liquidation loan-to-value limit, with $14.13 million borrowed against $162.85 million in available liquidity, a $176.99 million market size, and 7.98% utilization. At least one borrower appeared in the activity log during that period. These figures reflect a point-in-time view and do not represent Ethereum network conditions. Circle Mint enables eligible institutions to convert deposited Bitcoin into cirBTC collateral and borrow USDC through Morpho, transferring market risk to the lending venue. As of Sept. 20, Circle's reserve dashboard reported 948.75081803 cirBTC outstanding against 951.25857454 BTC in reserves, with approximately 397 cirBTC on Arc and 552 on Ethereum. Arc operates as a layer-1 network under a permissioned validator set, distinguishing it from other supported networks. The launch shortens the conversion path from Bitcoin to USDC but does not convert variable-rate DeFi credit into a fixed Circle loan. Sustained demand for cirBTC will depend on ongoing borrowing activity and market conditions following the launch.
