You will be able to claim your NFT soon after your donation. Once you complete your purchase,you will receive an email with claim instructions on how to receive your NFT. That email will provide you with a secret code (one-time password) and a link driving you to the Metamask to receive your NFT. Once your information is verified, the command to transfer the NFT to your wallet will be sent to the blockchain. There is no cost associated with the redemption process.
