cirBTC Brings Institutional Bitcoin Liquidity to Arc Network
Circle's cirBTC has launched on the Arc network, aiming to channel institutional Bitcoin liquidity into lending dApps and decentralized capital markets. The launch brings 1:1 $BTC-backed collateral into Arc's stablecoin-native ecosystem, making it possible for $BTC to become productive across various workflows.
The issuance of cirBTC operates under a structure where each unit represents one Bitcoin held in segregated custody, separate from the issuer's corporate balance sheet. This design preserves strict parity and prevents operational dislocations. Market participants can acquire the token via direct swap features on the Arc Portal or through official bridge transfers from the Ethereum network.
The rollout was accompanied by the simultaneous activation of lending markets on Aave V4 and Morpho, with Morpho absorbing over $150 million in deposits across its stablecoin vaults secured by the new wrapped $BTC asset. The development roadmap outlines the gradual addition of new trading pairs and the rollout of supplemental collateral options on the Arc Portal before the conclusion of the fourth quarter of 2026.
