Add/Update Collateral Asset

Anyone can submit a proposal to add a new type of collateral assets, update existing risk parameters. The process is the same as submitting any proposal to Acala/Karura network
We will outline specifics of the pre-image proposal regarding to adding a new type of collateral asset as follows
The example below adds DOT as a new collateral asset with the following parameters
  • stability fee
  • liquidation ratio
  • liquidation penalty
  • required collateral ratio
  • debt ceiling
  • DOT collateral auction size
Note: Updating risk parameters for an existing collateral asset uses the same extrinsics, and you only need to input the particular parameter proposed to be changed, while leaving the rest unchanged.
