  3. Liquidation Fees

Liquidation Fees

Liquidation fees apply only when an on-chain liquidation transaction is executed, not when a position merely becomes liquidatable.


How Liquidation Fees Work

When a liquidation is executed:

  1. A liquidator repays part or all of the borrower’s outstanding debt.
  2. In exchange, the liquidator receives collateral equal in value to the repaid debt.
  3. The liquidator also receives an additional portion of collateral as a liquidation bonus.
  4. After the liquidator’s repayment and bonus are satisfied, the protocol applies a liquidation penalty to the remaining collateral.

This penalty is taken directly from the borrower’s collateral as part of the same atomic transaction.

Interest During Liquidation
When a liquidator repays a borrower’s debt, the repayment includes any accrued interest. Any protocol fee applied to lending interest is collected as part of this repayment flow.

More details on interest-related protocol fees are covered on the Lending Fees page.


Liquidation Penalty

After the liquidator's repayment and bonus are satisfied, the protocol deducts a penalty from the borrower's remaining collateral.

Protocol Liquidation Penalty: 5% of remaining collateral


Where Liquidation Fees Go

All liquidation penalty fees collected by the protocol are routed to the Polyester Treasury.

The treasury is fully on-chain and publicly auditable.
