Visa has expanded its global stablecoin settlement pilot to Arc, Base, Canton, Polygon, and Tempo, bringing the total number of supported networks to nine. The company said the program has reached a $7 billion annualized run rate, with quarterly run rate growth of 50%, and that it now operates more than 130 stablecoin-linked card programs across more than 50 countries. The update reinforces the broader point that Visa is embedding stablecoin functionality into mainstream payment infrastructure as part of its effort to connect traditional payment systems with blockchain-based settlement rails, although the available information does not specify implementation dates, supported stablecoins on each network, or the exact operational role of each blockchain.
