Wrapped Aave Arbitrum WETH wallet

What is Wrapped Aave Arbitrum WETH (WAARBWETH)?

What you hold here is a claim on WETH sitting in the Aave v3 market on Arbitrum One, turned into a token with a stable quantity. The raw Aave position accrues by editing its own balance upward; this wrapped version leaves the count alone and lets the redemption rate do the moving, so one WAARBWETH buys back a little more WETH as time passes than it did when you received it.

There is a small irony in the fees. Transactions on Arbitrum are paid in ETH, the same asset that is locked up inside this token, and the wrapped share cannot be spent on its own gas. Keep spendable ETH in the wallet, especially before you try to redeem, since redemption is a transaction too.

Liquidity is the other thing to understand: your WETH is only free to come back out if the Aave market on Arbitrum has it available. This is a token whose behaviour depends on a lending market's state, not on an issuer's promise.

On the wallet side that leaves nothing to operate. The balance in the Tangem app is read straight from the contract each time you look, so a card that stays closed in a drawer for a year shows the correct figure the moment you open the app again.
