# Refund request Each wallet that has requested a withdrawal is monitored and if the refund is not made within the expected number of periods then reminders will be sent in the form of NFT. The reminders will be eliminated as soon as the wallet reimburses the amounts due. Reminder NFTs are visible to any other contract and constitute an incentive to repay the liquidity withdrawn without paying any kind of collateral. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
