yearn.finance wallet

What is yearn.finance (YFI)?

YFI is the governance token of Yearn, the protocol that popularised automated vaults on Ethereum. It is important to be clear about what the token is and is not. Yearn's vaults issue their own share tokens, usually written with a yv prefix, and those are the things that track a deposit inside a strategy. YFI is separate from all of them: it carries voting weight over the protocol, and holding it does not give a claim on any vault's contents and does not change in quantity on its own.

One quirk shapes every YFI balance. The token was issued in a very small number of units, so ordinary holdings are fractions rather than whole tokens, and a wallet will typically show several decimal places. That is normal and not a display error.

The canonical token lives on Ethereum; representations exist on other chains through bridges, and those are bridged claims rather than the original contract, which matters if you later want to vote or move size.

A governance token is usually held for a long time and signed with rarely, which is an awkward fit for a key that sits in a phone. With Tangem, the private key is created inside the card's secure element and never leaves it, and the backup is another identical card rather than a written phrase, though a seed phrase remains available if you prefer one. Keys you touch twice a year are better off in something that does not depend on a device you replace every few years.
