Constants and Mimir


The network launched with a set number of constants, which has not changed. Constants can be overridden via Mimir and nodes have the ability to vote on and change Mimir values.
See Halt Management for halt and pause specific settings.

Mimir setting can be created and changed without a corresponding Constant.



  • No Star or Hash - Constant only, no Mimir override.
  • Star (*) indicates a Mimir override of a Constant
  • Hash (#) indicates Mimir with no Constant.

  • MaxAnchorSlip*: Percentage (in basis points) of how much price slip in the anchor pools will cause the derived asset pool depths to decrease to
  • DerivedMinDepth. For example, 8k basis pts will mean that when there has been 80% price slip in the last MaxAnchorBlocks, the derived asset pool depth will be DerivedMinDepth. So this controls the "reactiveness" of the derived asset pool to the layer1 trade volume.
