Sometimes, gouvernance will manually set asset configuration, it is displayed in the AssetConfig entity. If an asset has a null AssetConfig, it is safe to assume that it was never explicitly set and is isolated.

For further tier information, refer to Tier Methodology.

borrowFactor and collateralFactor can be transformed in a decimal fraction by dividing by 4e9.
