What Aave announced
Aave posted on its official X account at 21:13 UTC on Tuesday 10 November 2026 (22:13 in Amsterdam) that cirBTC, Circle Wrapped BTC, is now live on Aave V3 and Aave V4 on Ethereum.
On both versions, cirBTC can be supplied as collateral to borrow assets like USDC. On V3 it sits in the Core market, and on V4 in the Core Hub.
Where to find it
In replies to the same post, Aave linked to the cirBTC reserve page of its V3 Ethereum market in the Aave app, to the cirBTC page on Aave Pro for V4, and to Circle's own cirBTC page for background on the token.
The announcement graphic shows the Aave ghost holding a blue bitcoin coin in front of repeated Aave, Circle and cirBTC names. Aave's post does not explain how cirBTC is backed or who can mint it, so read Circle's page before you buy or supply it.
Our take
Borrowing USDC against bitcoin without selling it is one of the most common uses of a lending market, and a wrapped bitcoin from the company behind USDC fits that neatly. Aave did not publish the loan-to-value ratio, liquidation threshold or supply cap for cirBTC in its post, so check those on the market page before you supply anything. Bitcoin can move fast, so borrow well below your limit to keep clear of liquidation.
