> Autonomous credit and savings solution

Opus provides autonomous credit facilities through dynamic interest rates and risk parameters on StarkNet.

Opus operates an autonomous credit protocol on StarkNet that enables borrowing against crypto portfolios including yield-bearing assets. The protocol adjusts interest rates and risk parameters dynamically based on market conditions. Users can borrow CASH stablecoin, provide liquidity to the stability pool, and participate in liquidations. The system uses autonomous controllers to maintain CASH's USD peg.

## Products

- [ Opus Protocol](https://thegrid.id/profiles/opus): Opus Protocol implements autonomous credit facilities that enable borrowing against crypto portfolios through dynamic risk parameters. The system manages collateralized debt positions, handles liquidations through a stability pool, and maintains a USD-pegged stablecoin using algorithmic controllers. (Decentralised Borrowing & Lending, Live, Main Product)

## Assets

- [CASH (CASH)](https://thegrid.id/profiles/opus): CASH is a USD-pegged stablecoin on Starknet minted by depositing collateral into Opus Protocol. It is used for payments, as collateral in DeFi applications, and to access liquidity while maintaining exposure to deposited assets. The protocol adjusts each borrower's interest rate individually based on their collateral composition, and applies a global multiplier to all rates when CASH trades above or below its peg to maintain price stability.
