Quant, an enterprise blockchain interoperability platform, achieved major institutional adoption on September 24, 2026, when seven UK banks including Barclays and HSBC processed live customer transactions on tokenised sterling deposits, and The Clearing House named it the interoperability layer for US payment infrastructure connecting 25 major banks. The company, founded by Gilbert Verdian with deep government and banking security credentials, has spent over a decade building institutional partnerships, culminating in embedding its Overledger technology across UK and US financial systems without requiring bridges or wrapped tokens.
