yearn.finance (YFI): What It Is, Uses and Risks

YFI is the governance token of Yearn Finance, a DeFi protocol that automates the search for yield on crypto deposits. Yearn began as a personal project by developer Andre Cronje. Its first job was to move stablecoin deposits between lending platforms such as dYdX, Aave and Compound as the floating interest rates changed. It later added vaults, which pool user funds, run strategies on other DeFi protocols, collect rewards, sell them for the underlying asset and reinvest.

The protocol is maintained by a group of independent contributors rather than a single company, and it is governed by people who hold YFI. The token is not a stablecoin and is not a deposit receipt. When you put funds into a Yearn vault you receive a separate vault token that tracks your share of the pool. YFI is a different asset with a different role.

As of 2026-11-05 YFI ranks around 340 by market capitalisation, which makes it a small-cap token. It sits in the DeFi, yield aggregator and governance categories. The figures later in this page give a sense of scale, but they change constantly and should be treated as a snapshot.

The main purpose of YFI is governance. Holders can propose and vote on changes to the protocol, such as which vaults and strategies are supported, how fees are handled and how the treasury is used. Voting power generally follows how many tokens a holder commits, so large holders carry more weight than small ones.

Public descriptions of the token also say that holders can receive a share of the cash flows from fees the protocol earns. The exact mechanism for this has changed over time through governance decisions, so anyone interested should read the current documentation and governance forum rather than rely on a summary. We do not give a firm statement of how fees reach holders today.

YFI is not required to use Yearn vaults. A person can deposit stablecoins or other supported assets and earn the vault yield without owning any YFI. The token is for people who want a say in how the protocol is run, or exposure to the project itself. Owning it does not guarantee any income, and vault yields are separate from the token's market value.

YFI has a fixed maximum supply of 36,666 tokens, and the total supply equals that maximum. At the time of writing, about 35,880 YFI were circulating, which is close to the cap. As of 2026-11-05 the price was about $2,034 per token, giving a market cap of roughly $73.0 million. The fully diluted value was about $74.6 million. The small gap between those two figures reflects the small amount still outside circulation.

The token is widely known for its launch. In mid-2020 it was distributed to people who supplied liquidity to Yearn's pools, with no pre-sale to investors and no allocation held back by the founder. This approach became known as a fair launch. Since then, a limited number of extra tokens have been minted and distributed through governance decisions, which is how the supply reached its cap of 36,666.

Because the supply is so small, each token is priced in the thousands of dollars. Trading volume over 24 hours was about $2.9 million at the time of writing, which is modest. Thin liquidity can make prices move sharply on relatively small orders.

YFI is primarily an ERC-20 token on Ethereum, where most of its liquidity and governance activity sits. Wrapped or bridged versions are also issued on other networks, including Fantom, Near, Harmony, Polygon, Gnosis Chain (xDai), Avalanche, Arbitrum, Heco, Base and Optimism. YFI is not the native coin of any chain, so you pay network fees in that chain's own currency, such as ETH on Ethereum.

Most people hold YFI in a self-custody wallet, or on a centralised exchange that lists it. It also trades on decentralised exchanges, where you swap against another token through a liquidity pool. Because one YFI costs thousands of dollars, many wallets and exchanges let you buy fractions of a token.

Bridged copies are not identical to the original. Each relies on a bridge or issuer, and some of the listed chains have seen reduced activity over time. If you use a non-Ethereum version, check that you have the correct contract address from an official source, and understand that you carry the extra risk of the bridge as well as the token. For governance, the Ethereum version is the one that matters.

YFI traded from around July 2020, and its all-time low of about $31.65 was recorded on 2020-07-18. It rose rapidly during the 2020 DeFi boom, when yield farming drew heavy attention, and reached an all-time high of about $90,787 on 2021-05-11. Yearn is often credited with starting the yield aggregator category, and its vaults inspired many similar products.

As of 2026-11-05 the token trades far below that peak. Its price had fallen by about 53% over the previous year, and it moved by roughly -0.6% over the past seven days. Those numbers describe the past and say nothing about what comes next.

Yearn's leadership also changed. The founder stepped back from day-to-day work, and the protocol has since been run by a community of contributors and governed by token holders. The project has launched several vault versions over the years. Older versions were retired, and users have been asked to migrate to newer ones. Yearn has also faced security incidents in the past, as many DeFi protocols have, so it is worth reading the project's own post-mortems for details.

Smart contract risk is the main concern with anything linked to Yearn. Vaults combine several layers of code: Yearn's own contracts plus every protocol a strategy touches. A bug or exploit in any layer can cause losses, and audits reduce this risk without removing it. Vault yields also vary and can fall to low levels when markets are quiet.

Governance risk matters for YFI itself. Because the supply is small, a few large holders can have a large influence on votes. Decisions can also be slow, and contributors may leave or change focus.

Market risk is significant. YFI is a small-cap token with modest daily trading volume, so prices can swing sharply and exits at size may be costly. The token has fallen by roughly half over the past year as of the date above, and it remains far under its 2021 high.

Finally, there are scam risks. Fake tokens and lookalike sites target popular DeFi names, and bridged versions add extra counterparty risk. None of this is advice to buy or sell. Consider only an amount you could afford to lose, and do your own research.

Since YFI is an ERC-20 token, any Ethereum-compatible wallet can hold it. For anything beyond a small amount, a hardware wallet keeps your private keys offline and is generally safer than a browser extension or a mobile app on its own. Write down your recovery phrase on paper or metal, keep it offline, and never type it into a website or share it with anyone, including people claiming to be support staff.

Before sending funds, check the token contract address against the project's official documentation, and send a small test transaction first. Be careful with token approvals. When you use a vault or a decentralised exchange, you often grant a contract permission to spend your tokens. Review these permissions from time to time and revoke ones you no longer need.

If you hold YFI to vote, you do so from the wallet that holds the tokens, so keep that wallet well protected. Leaving tokens on an exchange is convenient for trading, but you then rely on the exchange's security and cannot vote on-chain. Use official links from the project's own channels, and treat unsolicited direct messages and airdrop offers as suspect.
