For all the lending products working with an LP token the interest are credited to your lending contract in the form of LP tokens and can be claimed at any time or reinvested automatically via the compound interest function.
As long as they are not claimed, the value of the interest received in LP tokens can vary, depending on the diversification of the lending service at the time.
You can claim your interests by clicking on the "Claim" button of your lending contract. You will then be able to select the stablecoin of your choice, taking into account the value of the LP token in relation to the token being withdrawn at that moment.
For all the others lending products, interests are paid directly in the cryptoasset of the related lending contract.
