> There is no extant fiat payment system that settles in 1 second. In Europe all banks now offer instant wire transfers. (A regulation pushed by the European Commission to counter VISA…) It’s still often not free (0.75 euros at my bank I think), when 24h/48h wire transfers most often are, but I think I read the goal is for instant wire transfers to eventually be free (by regulation) It’s really instant! Across any European (IBAN) account. There’s also a growing use of a standardized QR code for IBAN account numbers, making the scan and instant transfer UX at least possible (but I never saw anyone do that yet)
