Гаманець для USDC yVault

What is USDC yVault (YVUSDC)?

A share, not a dollar

yvUSDC is what a Yearn vault hands back when you deposit USDC. It is an ERC-20 like any other, but it represents a share of the vault's holdings, and the vault tracks a price per share. The consequence catches people out: one yvUSDC is not one dollar, and it is not meant to be. Withdrawing converts your shares back into USDC at the current price per share, which is where the difference shows up.

Because the share is the position, transferring yvUSDC transfers the deposit itself. Send it to someone and they can withdraw the USDC; send it to a contract that does not know what it is and it can be stuck there. The vault is the only place shares are created and destroyed, so deposit and withdraw are contract calls on Ethereum paid for in ETH, not swaps.

One more thing to check before you trust a balance: the yvUSDC ticker has belonged to more than one vault. Yearn has run successive vault versions, and each deployment is its own contract with its own share price, so a figure quoted for one tells you nothing about another. Match the contract, not the name.

Supported networks in Tangem (1): Ethereum.

Your share count never moves on its own, and neither does anything else on your side - Tangem just queries the vault token balance when you open the app. A card in a safe is enough to hold a vault position that recalculates itself, and that is the reason to park yvUSDC on one rather than in something you have to keep unlocked.
