Гаманець для sETH2

What is sETH2 (SETH2)?

sETH2 came out of StakeWise's second version as the deposit side of its Ethereum staking pool: ETH went into the pool and the depositor got sETH2 back, mapped one to one against the ETH staked. The unusual part of the design is what sETH2 does not do. It does not rebase and it does not creep upward. Staking accrual was tokenized separately, as rETH2, so a wallet holding a stake in that pool showed a flat sETH2 figure next to a second token that moved. Holders who expected one growing balance often assumed something was broken.

StakeWise has since moved on to a newer staked-ETH token, osETH, and sETH2 belongs to the earlier generation. That makes it a legacy position rather than a live product: it is a plain ERC-20 on Ethereum, it takes ETH in the same wallet to move or convert, and the sensible assumption is that redeeming or migrating it will be a contract interaction you sign at some point rather than a simple transfer to another address.

Something held for that long is really a question about the key, not the token. In Tangem the key is generated on the card and stays inside its chip, and the backup is a second card holding the same key rather than words on paper, with a seed phrase available only if you deliberately want one. A dormant staking token from an older protocol version is exactly the kind of holding that outlives the phone it was set up on, and a card survives that change without ceremony.
