# Repay SuToken Liability

Users can repay the minted SuTokens to the Sumer Protocol up to the minted balance. 

### <mark style="background-color:blue;">Multiple Collateral Assets</mark>

By default, if multiple assets are supplied as collateral to mint SuTokens, the collateral available for withdrawal will be the asset with lower Loan to Value.&#x20;

### <mark style="background-color:blue;">Partial Repayment</mark>

Users can make partial repayment of their SuToken liability. On partial repayment, the SuToken liability will be non-zero and not all collateral is available for withdrawal.&#x20;

However, there is no interest accrual as minting SuTokens has no interest cost.

### <mark style="background-color:blue;">Mint Interest</mark>

The protocol has the option to charge users' interest on minting while repaying the minted SuTokens.&#x20;

<mark style="color:yellow;">**The mint interest is set as 0% at the launch of the protocol.**</mark>&#x20;

Any changes to the mint interest will be made through the governance process.&#x20;

The protocol has the option to charge users an exit fee while repaying the minted SuTokens.&#x20;

<mark style="color:yellow;">**The exit fee is set as 0% at the launch of the protocol.**</mark>&#x20;

Any changes to the exit fee will be made through the governance process.

Repayment of SuTokens is the burning of synthetic assets from circulation.&#x20;
