Stader ETHx wallet

What is Stader ETHx (ETHX)?

ETHx is Stader's liquid staking token for Ethereum: a receipt for ETH staked through the protocol, issued on Ethereum as an ERC-20 and redeemable back into ETH through the protocol's exit process or tradeable on the open market while you wait.

The part that confuses people first is that ETHx does not rebase. Your balance is a fixed number of tokens and it will sit there unchanged month after month. What moves is the exchange rate between ETHx and ETH, which the contract derives from the underlying validator balances, so the same token count corresponds to a different amount of ETH over time. A wallet showing you the same ETHx figure it showed last week is behaving correctly; nothing has stalled.

On the operator side, Stader's design lets a node operator run a validator by putting up 4 ETH rather than a full 32, with the rest coming from the pool - the reason the protocol describes itself as permissionless.

Practical points for holding: ETHx exists on Ethereum, transfers cost ETH, there is no activation and no token account, and unstaking goes through a withdrawal queue rather than being instant. Also keep in mind that DeFi contracts that accept ETHx are separate from the token itself.

A staked position is one of the longest holds most people have, which puts the weight on the key rather than the app. Tangem creates it inside the card and it never comes out; the backup you keep is another card carrying the same key, and no seed phrase has to exist on paper unless you decide you want one. Long positions deserve keys that outlive phones.
