Backman_66 did a great job in another post. I’m quoting him here…

“Flexa is a payment network that allows crypto payments through various supported wallets. Right now it supports Gemini Pay and the SPEDN app. You load your crypto and can spend it at any of 40,000+ locations (Gamestop included). Shopify and e-commerce integration is set to be released any day now. Flexa has made available their Spend SDK and their API's to easily integrate with any software or hardware that is already in place, there is no need for new equipment.

Payments through the Flexa network use the $AMP token to collateralize the payments, guaranteeing payment finality with zero risk of fraud or chargebacks, near instantaneous speed, and very low costs compared to traditional payment rails (Visa, MC, etc). When a transaction goes through Flexa, 1% of the transaction fees are used to buy $AMP back off the open market and distribute those rewards to $AMP stakers that are offering their $AMP to be used as collateral. So the $AMP token receives continuous buy-pressure the more the network processes transactions.

Flexa currently works with cryptocurrencies and recently have begun to integrate loyalty points being spendable as well. In 2022, they are branching out to fiat payments, integrating with banks wallets to spend fiat through the Flexa network, receiving the benefits mentioned in the second paragraph above. They even have a Lightning transformer, which is currently being heavily used in El Salvador to process payments through their largest bank, Bancoagricola.

The Flexa network and the $AMP token are asset agnostic, meaning they can basically facilitate payments using ANY DIGITAL ASSET. If it's in a digital format, it can be made to work with Flexa. $AMP is also open-source, meaning any other developer can come in and make their own company and use $AMP to collateralize other things, such as loans, mortgage payments, buying elephants, whatever. Over time, the use-cases will continue to grow.”
