# USDf (Synthetic Dollar) USDf is Falcon Finance’s overcollateralized synthetic dollar, minted when users deposit eligible collateral assets, including stablecoins (e.g., USDT, USDC, DAI) and non-stablecoin assets (e.g.,BTC, ETH, and [select altcoins](/supported-assets.md)). The overcollateralization framework is designed to ensure that the value of the collateral consistently exceeds the value of the USDf issued, preserving its stability across varying market conditions. Collateral deposited to mint USDf is managed through neutral market strategies, maintaining full asset backing while minimizing the impact of directional price movements. This approach reinforces the strength and reliability of USDf as an overcollateralized synthetic dollar. --- # 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.
