Гаманець для USDT yVault

What is USDT yVault (YVUSDT)?

yvUSDT is a vault share, not a dollar. Deposit USDT into the Yearn vault and you receive a number of shares; the vault puts the pooled USDT to work through strategies, and the value of one share is tracked by a price-per-share figure that moves up as the vault's holdings grow. Withdrawing burns your shares and returns USDT.

This is why the balance behaves in a way that confuses people used to stablecoins. Your yvUSDT count sits still. It does not tick upward, and one yvUSDT is not one dollar - it is worth whatever the vault's current share price says, which is why the share count you got on deposit is smaller than the USDT you put in. Reading the position means multiplying shares by share price, not reading the token count as a dollar figure.

The share token is a transferable ERC-20, so whoever holds it can redeem it. Gas for depositing, transferring and withdrawing is ETH. Note also that Yearn has run more than one generation of USDT vaults; shares of an older vault redeem against that vault, so check which one your token belongs to before moving it.

Supported networks in Tangem (1): Ethereum.

Since the position moves through the share price rather than through anything you do, a card in a drawer is a perfectly active way to hold it: Tangem reads the current state off Ethereum whenever you open the app, and the card only ever wakes up for a withdrawal.
