If you need to change your payment method or you simply want to check it, go to the ‘Subscription’ section within Polkadot Tiger.
You can find it by logging into the tool. Then navigate to the settings icon in the top right corner. After clicking it, select the ‘Subscription’ option.
The second section will show you the payment method you are using. You will see the last 4 digits of the credit card you provided and its expiration date. This is also the place to disconnect this card from your Polkadot Tiger account by clicking on the x next to the expiration date.
Below the information about the card, you have the option to add an additional payment method. If you click here, you will be taken to a page where you need to input the new credit card details. You can also set this new card as your default payment method.
