We currently use Metamask browser extension to confirm your identity. Metamask is an ethereum private wallet where you can store and transact with eth. The browser extension is available in Chrome and Safari only. Never copy/paste your seed phrase. Once you have a metamask account you can start buying cards here. If you are an artist that would like us to mint cards for you, please pay $2.99 below per card by clicking one of the buttons below, and then we will gift them to you so you can set your own price. If you have any questions, please email us at firstname.lastname@example.org. Thank you!
