# Classic Yield ### Overview The Classic Yield function within the Earn tab allows users to stake their minted USDf in exchange for yield-bearing sUSDf, and also unstake their sUSDf. Users can stake USDf without any lock-up period, allowing them to flexibly unstake sUSDf back into USDf at the prevailing sUSDf-to-USDf Value at the time of unstaking.\ Refer to the [Mint](/resources/quick-app-guide/navigating-the-swap-tab/classic-mint.md) section under the [Swap](/resources/quick-app-guide/navigating-the-swap-tab.md) tab for further details on acquiring USDf. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
