The Financial Conduct Authority (FCA) selected four firms to test stablecoin services in its regulatory sandbox, naming Revolut, Monee, ReStabilise and VVTX1. Revolut is the headline: Britain's most-valued private fintech at roughly $45bn, still chasing the full UK banking licence it first sought in 2021.
A regulatory sandbox lets a firm trial a product under FCA supervision before the rules around it are finalised. For a stablecoin issuer, that supervision is the whole point, because the UK framework for fiat-backed tokens is being drafted now rather than settled.
The regulator also opened a second cohort of its AI Lab, eight firms testing AI tools with access to Nvidia compute and FCA data, following the first AI Live Testing intake in April. The posture is consistent with the FCA's drive to thin the rulebook, having cut Senior Managers and Certification Regime roles by 15% in the spring. For a fintech founder, a sandbox slot is the difference between building toward an unwritten rule and testing inside one the regulator is writing alongside you.
