Lenders can redeem funds once a vault has reached its maturity date (or depending on the vault's configuration, once liquid funds are available).
When redemptions are available, a lender can redeem LP tokens for underlying tokens by calling withdraw on the token smart contract.
Note that for some vaults, redemptions not be available until the vault's maturity date or may be processed at the manager's discretion.
Please review and confirm details on each vault before lending.
