Wrapped Aave Ethereum USDC wallet

What is Wrapped Aave Ethereum USDC (WAETHUSDC)?

Think of WAETHUSDC as a receipt for a receipt. USDC goes into an Aave market on Ethereum and comes back as an aToken, whose balance rises on its own as interest accrues. That upward-drifting balance is exactly what many contracts cannot cope with, so the wrapped version pins the token count in place and lets the value sit in the exchange rate you get when unwrapping.

The lookalike problem here is real and worth naming. USDC, the aToken, and this wrapper all show a dollar-ish figure in a wallet list, and only one of them is the stablecoin itself. This is not redeemable at an issuer, it does not move on any of the other chains USDC is native to, and its balance will never equal the USDC amount you started with. Reading the full token name rather than the ticker is the habit that keeps the three apart.

Everything happens on Ethereum, and every action - transfer, unwrap, withdraw - costs ETH.

Supported networks in Tangem (1): Ethereum.

On the transaction screen Tangem spells out which token and which network an outgoing transfer belongs to, and the card only signs after you have tapped it, so there is a moment to confirm you are sending the wrapper and not the stablecoin sitting one line above it. When three similar-looking entries share a wallet, a signature that waits for a physical confirmation is the arrangement that keeps mistakes rare.
