Гаманець для StakeWise Staked ETH

What is StakeWise Staked ETH (OSETH)?

StakeWise V3 splits staking into vaults: an operator runs validators inside a vault, and osETH is the token minted against the ETH staked there. What sets osETH apart from other liquid staking tokens is that it is intentionally overcollateralized - a vault can only mint osETH up to a fraction of the ETH it has staked, so the token in aggregate is backed by more staked ETH than there is osETH outstanding.

Buying osETH rather than minting it means none of the vault side comes with it: no position to top up, no collateral ratio to watch, no validator to pick. What you hold is a token whose exchange rate against ETH moves as the validators behind it accrue, while the token count in the wallet never changes. That is the expectation to set - osETH does not grow by the unit, it grows by the rate.

Supported networks in Tangem (2): Arbitrum One, Ethereum.

The Arbitrum osETH is bridged rather than separately issued, and redemption back to ETH settles on Ethereum mainnet, so unwinding from the L2 means a bridge hop and gas at both ends.

Nothing in this position needs attending to in between. Tangem's app pulls the balance and the current rate from the chain on its own, and the card only comes out when you decide to move or redeem - which can be years apart. A position that grows without a signature is one you can reasonably leave to a card that spends most of its life switched off.
