Wrapped Aave Base WETH wallet

What is Wrapped Aave Base WETH (WABASWETH)?

Plain ether goes through three changes to become this token. First it is wrapped into WETH, the ERC-20 form contracts can handle. That WETH is supplied to Aave's market on Base, which issues an aToken that grows in balance as borrowers pay into the pool. This asset is the fixed-share version of that aToken: the count in your wallet stays the same, and the amount of WETH a unit redeems for is what moves.

So you are holding ether exposure in a form that is three steps from spendable ETH. It cannot pay a Base transaction fee, and it will not show up in a wallet as an ETH balance. Unwinding runs in reverse: redeem the share for the Aave position, withdraw WETH from the market, unwrap WETH to ETH. How much can be withdrawn at any moment depends on how much of the pool's ether is out on loan; when borrowing is heavy, part of the supply is simply not sitting there to be taken.

Each of those steps is a separate signed transaction paid for in ETH, so keep ordinary ether in the same wallet next to this token; signing happens by holding the card against the phone, with nothing to charge or plug in. Unwinding a position like this is fiddly enough without the wallet adding steps of its own.
