# Call Backs

After a lender has supplied liquidity to a pool, they may request a call-back for early withdrawal. However, requesting withdrawal before the maturity date does not create an obligation for the borrower to repay. If the borrower opts to repay, interest will only be due on the amount of blocks that have elapsed since the pool's inception.
