JPMorgan has expanded its blockchain-based Kinexys payment network to support British pound (GBP) accounts, addressing the USD dominance in the $230 billion stablecoin market. While 80% of Kinexys volume remains in USD, demand for GBP transactions is growing. This follows the addition of euro support last year. Kinexys processes over $2 billion in daily transactions, offering faster, cost-effective fiat payments. Initial participants include SwapAgent (under LSEG) and commodities giant Trafigura. This move enhances cross-border payment capabilities beyond the dollar.
