Wrapped XTZ wallet

What is Wrapped XTZ (WXTZ)?

Tezos runs on liquid proof of stake, and the coin behind this token, XTZ, is unusual in what it lets a holder do while simply sitting in an address: delegate to a baker without moving the coins anywhere.

WXTZ carries none of that. It is an ERC-20 claim on XTZ living on EVM chains, and on those chains the Tezos rulebook does not apply. No delegation, no participation in amendment voting, no baker relationship. What you hold is exposure to the coin plus the ability to use it where EVM contracts live, and the moment the tokens go back to Tezos through whatever bridge or issuer produced them, the native behaviour returns.

Address formats are the other trap. A real Tezos address starts with tz or KT and looks nothing like the 0x address a wrapped token uses, so the two cannot be confused - but two EVM chains look identical to each other, and WXTZ sits on more than one of them.

Supported networks in Tangem (4): Arbitrum One, Base, Ethereum, BNB Smart Chain.

Each one is tracked as its own balance in the app, and the network the transfer leaves on is stated on the screen you confirm before the card signs. Reading it takes a moment and is the only moment that counts, because after the signature the transaction belongs to that chain alone. For a coin you hold in wrapped form across several networks, having the chain named at the point of signing is the practical argument for keeping it here.
