1. Go to the pool's Etherscan/Polygonscan page. You can find it by inspecting your transactions on your account's Etherscan page under _Erc20 Token Txns_.
2. Click _View All_ and look for Ocean Pool Token (OPT) transfers. Those transactions always come from the pool contract, which you can click on.
3. On the pool contract page, go to _Contract_ -> _Read Contract_.
7. Divide the number by 2 to get the maximum of pool shares you can send in one pool exit transaction. If your number retrieved in former step is bigger, you have to send multiple transactions.
