vault liquidation to ensure maintenance of system c-Ratios
as a collateral backed debt issuance platform, it is important that vault and system collateral is maintained at appropriate levels to back any fxToken debt; ensuring each remains representative of their underlying currencies face value. the core principles, underpinning the protocol liquidation process are;
- if the collateral value, or c-Ratio, of a vault falls below its minimum c-Ratio, that vault is deemed to be 'at risk' or "underwater'. In this state it can be subject to a 1:1 redemption call on its collateral by fxToken holders.
- if a vault's c-Ratio falls below its liquidation trigger it will automatically be subject to a liquidation process to repay excessive debt and bring the collateral ratios back to acceptable limits.
- the protocol makes use of its fxKeeper pools to ensure that liquidation is promptly triggered and executed.
