3\. After deposit, you will receive some LP tokens representing your shares of the OMM pool. And you can check the transition record in the **Transaction History** table.

4\. The OMM will use the fund in its liquidity pool to trade options on markets, and make profits from it. When you want to withdraw your liquidity from the OMM pool, you can go to the **Withdraw** section and enter the amount to withdraw. It will burn your LP tokens and send USDC tokens back to your wallet according to the amount of burned LP token.
