This proposal aims to deprecate (phase out) Compound's lending markets, known as 'Comets,' on the Polygon and Unichain networks. It suggests setting all collateral supply caps to zero, meaning no new assets can be supplied to these markets. Additionally, it proposes reducing the collateral factors for existing assets by 50% (except for MaticX, which goes to 0%) and setting the supply interest rate to zero, ensuring all interest paid by borrowers goes to the protocol's reserves during this transition.
If passed, users will no longer be able to supply new collateral to the Polygon and Unichain Comets, and the value of existing collateral will be recognized at a lower rate, potentially leading to liquidations for some borrowers. This change primarily affects users who currently utilize these specific Comets, as Compound aims to consolidate its operations and resources.
