About Wrapped Aave BTC.b

A non-rebasing Aave receipt token: the ERC-4626 wrapped form of the aToken issued for a deposit of Avalanche Bridged Bitcoin (BTC.b) in the Aave lending protocol. An aToken balance grows as supply interest accrues; a waBTC.b balance stays fixed and the redemption rate rises instead, so one share comes back as a growing amount of BTC.b. Protocols that cannot handle a rebasing balance need it in that shape, which is why this is what sits inside Balancer's Aave-boosted pools. Aave deploys one wrapper per market; this asset covers them all, on every chain.
