Spark Prime has proposed modifications to its collateral system on the Ethereum network, specifically for SparkLend. This proposal aims to disable sUSDS and sDAI as collateral by setting their supply caps to one and adjusting the maximum Loan-to-Value (LTV) ratio to 0%. The liquidation threshold for stablecoin emode will remain unchanged, ensuring existing positions are not subjected to new liquidation risks. Further adjustments include increasing the PYUSD interest rate model benchmark to align with the Sky Savings Rate (SSR), while also reducing Slope 1 to 2%. These changes aim to stabilize borrowing rates and promote increased PYUSD circulation. The proposal now awaits review from Sky governance and Stability Facilitator before being implemented through a subsequent execution vote.
