Efficiency Mode (eMode)
The High Efficiency mode feature (or "eMode") is designed to maximise capital efficiency when collateral and borrowed assets are correlated in price.
POOL_ADMIN, set by Maker Governace, can configure a maximum of 255 eMode categories, with each
EModeCategoryhaving following risk management parameters:
- LTV (Loan to value)
- Liquidation threshold
- Liquidation bonus
- A custom price oracle (optional)
💡 Category 0 is reserved as the default non-eMode category. All the assets listed on Spark Protocol, by default have category 0 (which indicates the standard operational mode).
All Assets listed on Spark Protocol can be set to any of the pre-configured
The correct categorisation is not enforced on-chain and needs to be maintained by the
POOL_ADMINSselected via the Maker Governace vote.
eMode also offers the possibility of introducing a specific price oracle for a certain category.
If the user has supplied liquidity to the protocol, the user
eModecategory is set to 0 by default.
The protocol allows user to set the user eMode category to any of the
eModeCategoriesconfigured by the
PoolConfiguratorgiven the following conditions holds true:
- all the borrowed assets of the user are in the chosen category.
- changing eMode doesn’t leave user position under-collateralised
