Simple Summary

This SCCP proposes to update the maxLiquidationDelta and maxPD parameters to 10 and 20 bp respectively on the FTM and BCH markets.

Abstract

The parameters description are as follows:

  • The maxLiquidationDelta is the maximum pd impact possible from a given liquidation, beyound which liquidation takes place via the endorsed liquidator.
  • The maxPD is the maximum pd distance from zero, beyound which liquidation takes place via the endorsed liquidator.

Motivation

The maxLiquidationImpact parameter is normally calibrated as the sum of maker and taker offchain fees while maxPD is double maxLiquidationImpact. The proposed changes in this SCCP are necessary, in order continue to rollout liquidations safely, taking into account the changes proposed in SCCP-2019 which proposed to alter the offchain makerFee.
