Collateral Rate by Asset Group
Sumer determines the ability to borrow assets or mint SuTokens based on the group of asset (homogeneous and heterogeneous) supplied as collateral.
Borrow/ Mint within same asset group = Higher LTV similar risk profile
Borrow/ Mint across different asset group = Lower LTV due to varying risk profile
Collateral Rate (i.e. Loan-to-Value ratio) signifies the value available to be borrowed/ minted for each collateralized asset.
A Collateral Rate of 75% means that the users can only borrow up to 75% of the value of their collateralized assets.
The Collateral Rate for each asset is set based on several inherent characteristics of the asset, such as availability in the reserve, normalized volatility and the asset’s liquidity in the market.
NOTE: These ratios and their parameters will be determined by the Sumer Team at launch. As the protocol matures and the necessary framework is in place, the governance of these parameters will be opened to the community via Sumer’s governance process.
The maximum value of asset that can be borrowed when collateral and borrowing asset belong to the same homogeneous group
For e.g. Borrowing ETH by supplying stETH
The maximum value of SuToken that can be minted when collateral and SuToken asset belong to the same homogeneous group
By design, The Mint Rate has the highest LTV for supplied assets (close to 1)
For e.g. Minting suETH by supplying ETH
The maximum value of asset that can be borrowed or minted when collateral and borrowing asset belong to the different heterogeneous group
For e.g. Borrowing ETH by supplying USDC or Minting suETH by supplying USDT
