# USH * USH is a s**tablecoin**, which is a type of cryptocurrency that's designed to be less volatile than other cryptocurrencies because they're pegged to assets that are relatively stable. USH is designed to hold a stable value relative to one US Dollar. * USH is c**rypto-backed**, because it uses cryptocurrencies as collateral. Users can *Deposit* one of the accepted [Collateral Types](/docs/protocol/collateral-types.md) to borrow USH. * USH is o**ver-collateralized**, which means that the backing collateral always needs to have a higher value than the amount of USH in circulation. The purpose of the over-collateralization is to account for volatility. * USH is **decentralised***.* [Collateral Types](/docs/protocol/collateral-types.md) do not have a single point of control, collateral vaults are non-custodial*,* anyone can borrow USH, anyone can trigger a [Liquidation](/docs/protocol/liquidations.md) and [Interest Rates](/docs/protocol/interest-rates.md) are adjusted onchain by the system. --- # 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.
