This is the first time it has run a single-asset-class cohort focused exclusively on stablecoins, digital assets designed to maintain a stable value, usually by being backed 1:1 with fiat currency or high-quality reserves. Firms accepted into the cohort can: - Issue and redeem stablecoins in a live UK environment - Test custody, wallet, and payment services - Run real-world consumer or institutional transactions - Receive direct guidance from an assigned FCA Innovation Case Officer - Feed findings straight into the Treasury, FCA, and Bank of England rule-writing process > The sandbox operates under restricted authorisations, meaning consumer protections remain in place while firms push technical and commercial boundaries.
