The United States offers unique opportunities for FinTech companies across its 50 states, each of which serve as laboratories for innovation and regulation. Arizona's efforts place it among several other states at the forefront of financial technology, laying the groundwork for companies to test their products and services in a safe and permissive regulatory environment. In the meantime, other states are able to observe and learn from Arizona's efforts in order to implement regulatory sandboxes and, eventually, sound regulatory frameworks of their own.
