# Isolation Mode #### Concept Isolation Mode enables new assets to be listed with controlled risk. When a borrower uses an isolated asset as collateral, they **cannot simultaneously use other assets as collateral**, but can still supply them to earn yield. In this mode, borrowing is restricted to select stablecoins approved by governance, **with borrowing capped by a defined debt ceiling** to ensure protocol stability. #### Best Practise If you’re supplying an isolated asset, consider creating a new account to avoid limiting your overall borrowing power. This approach helps maintain capital efficiency across your positions.
