A NFT holder can withdraw their Data Rewards that are showing available on their NFT dashboard at any time. Click on the withdrawal button that is shown on the "available" funds balance.
You will see a pop up which will have your wallet address pre populated with the wallet attached to that particular NFT. Enter the amount of USDC you would like to withdraw.
You will also need to receive a verification code, click “get code” which will send a code to your email address, enter the verification code in the space provided and click “withdraw”. You will receive the funds within 24 hours.
Data Rewards will only go into the available balance if the option to “grow” rewards is toggled off and says “not growing”
