# Deprecation of Linea and Mantle Comets\n## Simple Summary\n\nGauntlet recommends the following risk parameter changes to deprecate all active comets on Linea (USDC and WETH) and Mantle (USDe). These markets have seen limited adoption since deployment. The proposed changes set all collateral supply caps to 0, reduce borrow\ncollateral factors by 50%, and update interest rate parameters to eliminate reserve\ndegrowth across all three comets. Liquidation factors are left unchanged throughout.\n\n
AI summary
This proposal aims to deprecate, or effectively shut down, the Compound protocol's lending markets on the Linea and Mantle networks. These markets, known as 'Comets,' have seen very little use. The changes involve setting supply caps to zero, meaning no new assets can be deposited, and significantly reducing the collateral factor for existing assets, which lessens their value as collateral for borrowing. Additionally, interest rate parameters will be adjusted to prevent the protocol's reserves from shrinking.
If passed, users will no longer be able to deposit new assets into the Linea and Mantle Comets, and the borrowing capacity of existing collateral will be reduced. This primarily affects users who are currently utilizing these specific, low-adoption markets, as they will need to adjust their positions. The Compound protocol benefits by reducing its exposure to underutilized and potentially risky markets.
