# General

**What is Solido Cash?**

Solido Cash enables users to borrow funds using multiple forms of yield-generating collateral, including $SUPRA and yield-amplified or auto-compounding yield tokens. Users can deposit their collateral into the Solido Protocol and receive $CASH tokens in return. The amount of $CASH they can borrow depends on the value of their collateral.

The main version of the Solido Cash can support only non-censorable assets to preserve its safety and the core value propositions of $CASH and Solido.

**What are the key benefits of the Solido Protocol?**

Solido Cash not only provides users with interest-free loans but also helps to reduce sell pressure on cryptocurrency assets by allowing users to borrow against them.

Additionally, the Solido Cash is non-custodial, programmatic, and transparent, upholding the ideals of decentralized finance. Our fees are transparently paid upfront and visible from the user interface.

**What is $CASH?** 

$CASH is an over-collateralized debt token issued by Solido Protocol. $CASH can be minted by depositing collateral on the Solido Protocol. $CASH has a:

Hard price ceiling: $CASH Troves' maximum[ Loan-to-value (LTV)](/solido/cash-protocol/troves-and-collateral.md#collateral-ratio-and-loan-to-value-ratio) with collateral creates a natural price ceiling. When the $CASH exchange rate exceeds that level, borrowers can make an instant profit by borrowing the maximum amount against their collateral and selling $CASH on the market for more than the ceiling price.

Hard price floor: The ability to redeem $CASH for collateral creates a hard price floor, below which arbitrage opportunities become profitable.

We call these "hard peg mechanisms" since they are based on direct processes.
