txSync Bridged wstETH (zkSync) wallet

What is txSync Bridged wstETH (zkSync) (WSTETH)?

This is wstETH at one remove. The original is Lido's wrapper around staked ether on Ethereum: a non-rebasing token whose balance never moves while the amount of stETH it unwraps into keeps climbing. What sits on zkSync under this name is a bridged representation of that token, minted on the rollup when the Ethereum-side wstETH was locked by a bridge.

That extra layer is the thing to understand before you hold it. Your claim runs through the bridge that issued it, not directly to Lido, and getting back to Ethereum wstETH - let alone to stETH or ETH - means going out the same way you came in. It also means the rollup can carry more than one token calling itself wstETH, from different bridges or from a canonical deployment, and those are not interchangeable even when the ticker and the logo match. Check which contract a market, a pool or a counterparty actually means.

Day to day it behaves plainly: an ERC-20 on zkSync, transfers paid in ETH on the rollup, and a balance that stays at whatever number you received. Nothing accrues into the token count.

Supported networks in Tangem (1): zkSync.

Tangem keeps this token as its own line item under the network it actually lives on and names that network on every outgoing transfer, which is worth a glance before the card signs - with bridged assets the destination chain is the assumption most likely to be wrong. Having that in front of you at signing time is why a bridged wstETH position is comfortable to keep here.
