A coalition of more than 140 companies, including Visa and Mastercard, has launched Open Standard and Open USD, a dollar-pegged stablecoin aimed at the $300 billion stablecoin market. According to NS3.AI, Open USD is expected to go live later in 2026 across multiple blockchains, including Solana, Stellar, Base, and Polygon. The coalition said the stablecoin will not charge minting or redemption fees. It also plans to share most reserve interest with companies that use the stablecoin.
