Unagii ETH wallet

What is Unagii ETH (UETH)?

Depositing ETH into Unagii's Ethereum vault gives back UETH, and that token is the whole record of the position. It is a vault share rather than a wrapped copy of ETH: one UETH does not stay equal to one ETH, and how much ETH it converts back into is decided by the vault's internal exchange rate at the moment of withdrawal. The UETH balance itself does not move. Nothing arrives in the wallet, nothing has to be claimed, and seeing the same number month after month is the expected behaviour, not a stuck balance.

Two practical consequences follow. UETH pays for nothing on Ethereum - every transfer, approval and withdrawal is settled in ETH gas, so a little plain ETH has to sit in the same wallet or the position cannot be unwound. And because UETH is an ordinary ERC-20, it can be sent to any Ethereum address, but only the vault contract turns it back into ETH; someone who expects ETH and receives UETH is handed a token they cannot open.

Supported networks in Tangem (1): Ethereum.

A share token that sits still is easy on a card wallet: Tangem reads the balance straight from the chain when the app opens, and the card can stay in a drawer between the deposit and the day you decide to exit. For something whose entire point is to be left alone, that absence of upkeep is the argument for keeping it there.
