Aave said on November 10, 2026 that Circle Wrapped Bitcoin, cirBTC, is now live as collateral on Aave V3 and Aave V4 on Ethereum.

In an official post at 21:13 UTC, Aave said cirBTC can be supplied as collateral to borrow assets such as $USDC in the Aave V3 Core market and the Aave V4 Core Hub. Follow-up replies pointed to the live V3 reserve page, the V4 market on Aave Pro, and Circle's cirBTC product page.

Circle describes cirBTC as a wrapped bitcoin token backed 1:1 by native $BTC, with reserves that can be independently verified onchain, and already issued on Ethereum and Arc. This live listing is separate from Aave's November 9 plan to add native Bitcoin collateral later through Babylon vaults, which is not live yet.
