We no longer can accept payments for Nano through Shopify. Everything has to be done manually. I am fine processing Nano payments manually because I believe in the future of it and want to help with adoption. If you are interested in purchasing a pair of glasses with Nano, please shoot me an email at hello(at)rauchroad.com and I'll work with you to make it happen. I am going to continue to search for new ways to get Nano integrated into the site. We have also added the ability to pay with other cryptocurrencies through Coinbase Merchant.
