My partner repeatedly tells me that I’m not as old as I think I am, but I remember playing in public sandboxes as a kid. I’m honestly not sure people make those anymore—they’re probably “unsafe” or “unhygienic” or something. Still, I remember the freedom of a sandbox. In the short run, you can create your own castle, moat, and entire surrounding village if you want.
Like most sandboxes in the tech world, the Arizona fintech sandbox is geared toward securely testing new software. There’s no actual sand involved, which makes cleanup much easier.
