How UMA works
UMA uses the Bitcoin Lightning Network for fast, low-cost, and efficient payments. Like SMTP, the protocol enabling people to send and receive emails seamlessly, UMA enables a user experience that allows people to reliably send and receive money 24/7 in the currency they choose. UMA uses the Bitcoin Lightning Network behind the scenes to enable instant, real-time, low-cost settlement. UMA is open-source which means any wallet, exchange, or bank can integrate the standard and build new payment experiences. UMAs are also interoperable; all that's needed is for both recipients to have an enabled account with their provider of choice.
People begin by claiming their own personalized UMA on their preferred wallet, exchange, or bank. During setup, they also choose a currency preference, so every time they receive a payment, it’s in the currency they want. Once they have their UMA they can send money to anyone else with an UMA-enabled account.
Example payment flow
UMA works even when the recipient doesn’t have an UMA yet. UMA users can help their friends and family sign up. A sender can generate an invite link to share with the person they want to send money to. The invite recipient will then be guided to find a wallet, exchange, or bank in their country. Then they can set up their own UMA-enabled account so both parties can send and receive payments. It's simple and fast!
