Flexa is a New York City-based company that manages the Flex Network Protocol, a blockchain-based payment network that allows users to spend cryptocurrency at physical retailers via its Spedn app. At checkout, the app generates a QR code that retailers scan to receive their preferred fiat currency for the transaction, while the equivalent amount of cryptocurrency is deducted from users’ wallets within the app. The use of the network’s native token, AMP, allows for instant payments.
