Multiple credible sources, including Ledger Insights, UK Finance, and Quant's own website, confirm that Quant was selected as a technology partner/provider for the UK's Regulated Liability Network (RLN) initiative. This project, involving major UK banks, is an experimental phase to explore payment options and infrastructure for a tokenized sterling/digital pound. While this is a trial/prototype phase rather than the final national infrastructure, the statement that Quant is building payment infrastructure for a UK tokenized pound project is factually supported by the evidence.
