Lesson 4 of 5

How a regulatory sandbox works: eligibility, testing, safeguards and exit

A regulatory sandbox lets a firm test a new product with real customers, under supervision and within limits agreed in advance. This lesson follows a practical guide published by CGAP and the World Bank and a report of the three European Supervisory Authorities: what an authority settles before it opens a sandbox, who may enter, how a test is set up and bounded, with a worked example, which safeguards protect customers, and how a test ends.
