Answer: Unfortunately, if the website is not allowing you to claim your staking rewards, then you will need to access the smart contract to do so. You can find the details of the smart contract on the website, or you can contact the website's customer service team for assistance. Once you have the details of the smart contract, you can use a blockchain explorer to access it and view the details of your staking rewards. From there, you can claim your rewards by sending a transaction to the smart contract. Be sure to double-check all the details of the transaction before sending it, as it is not possible to reverse it once it is sent.

Can you give me the smart contract sir
