Sanctuary DEX™ has a unique, fully decentralized merchant payment system. At the heart of our merchant payment system is a unique feature on our website that allows merchants to print out special merchant payment QR codes on merchant payment signs to put by the point of sale. The signs allow customers to pay merchants directly point to point without the merchant having to supply their public key to the customer. Other companies doing cryptocurrency merchant pay are either centralized (which defeats the purpose of DEFI) or they require the vendor to expose their public keys, which means customers could check the balances and track transactions for the merchant’s wallet.
