Гаманець для Wrapped Aave Avalanche BTC.b

What is Wrapped Aave Avalanche BTC.b (WAAVABTC.B)?

Start with what BTC.b is, because the rest depends on it. BTC.b is bitcoin carried onto Avalanche through the Avalanche Bridge: the underlying BTC is held in custody and an ERC-20 representation circulates on the C-Chain. This token goes one step further - that BTC.b has been supplied to the Aave market on Avalanche, and the deposit is held in a wrapped, non-rebasing form, so the unit count stays put while the amount of BTC.b each unit redeems for is what shifts.

The thing holders trip over is not the wrapper, it is the family resemblance. Avalanche has carried more than one kind of bitcoin: BTC.b from the Avalanche Bridge and older bridged forms that also present themselves as bitcoin. They are different contracts and are not interchangeable, and a wrapped Aave position on top of one of them is different again. Read the full token name, not the bitcoin symbol in it, before you move anything.

Also worth knowing: transfers are Avalanche transactions and cost AVAX.

Tangem lists each of these lookalikes as its own entry with its own balance, and the screen names the asset and the network it is going out on before you hold the card to the phone to sign. Where several tokens wear the same three letters, being shown exactly which one is leaving is worth the extra second, and Tangem makes that second unavoidable.
