Wrapped Aave wstETH

A non-rebasing Aave receipt token: the ERC-4626 wrapped form of the aToken issued for a deposit of Wrapped Staked Ether (wstETH) in the Aave lending protocol. An aToken balance grows as supply interest accrues; a wawstETH balance stays fixed and the redemption rate rises instead, so one share comes back as a growing amount of wstETH. 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. wstETH accrues Lido staking rewards through its own exchange rate, so the deposit earns those on top of Aave supply interest.
