While stablecoin ventures race to roll out digital currencies to consumers and businesses, Visa and Mastercard are adding up opportunities to collaborate. Visa, the largest U.S. card network, and its smaller rival Mastercard have become eager to join in the evolving stablecoin enterprises. Visa CEO Ryan McInerney said something similar about stablecoin strategy last week when he was asked about who was winning the stablecoin race, as a barrage of companies announce stablecoin launches. Also taking part in the Arc project are other payments companies, including digital payments services provider Global Payments and cross-border money transfer company MoneyGram, according to the release. That was another development that suggests the card networks are carving out a spot for themselves that sits above the stablecoin fray, or maybe more specifically between the stablecoin networks.
