Mastercard integrated DAI for settlements on June 3, 2026, adding DAI to its on-chain settlement network across eight blockchains. Mastercard opened its global card-settlement network to regulated stablecoins, including DAI, on eight blockchains like Ethereum, Solana, and Polygon, enabling issuers and acquirers to clear card transactions on-chain with intraday, weekend, and holiday settlement for the first time. Initial adoption starts in the US and Latin America with partners like Cross River Bank.
