Circle Launches Bitcoin-Backed USDC Loans
Stablecoin issuer Circle has introduced an institutional Bitcoin-backed USDC loan service through its Circle Mint platform. The tool, called Digital Asset-Backed Borrowing (DABB), allows institutional entities to secure immediate liquidity in digital dollars without selling their Bitcoin reserves. Clients deposit Bitcoin to mint Circle Wrapped Bitcoin (cirBTC), which is held under fiduciary standards with a 1:1 backing ratio. Users then interact from a non-custodial Smart Wallet with integrated decentralized finance (DeFi) markets, with Morpho protocol being the first to support cirBTC and allow fund withdrawals. The resulting USDC balance is credited directly to the user’s corporate account on Circle Mint.
