Anchorage Digital Bank said it now provides custody for the Mexican peso stablecoin MXNB on six blockchains: Arbitrum, Base, Ethereum, Polygon, Avalanche and Arc. Bitso has also listed Western Union’s USDPT and Tether’s USAT alongside MXNB. Mexican customers can buy and sell USDPT with pesos in Bitso’s app, while Western Union agents with Bitso Business accounts can exchange it for other supported currencies.
Bitso says its infrastructure already processes 15% of U.S.-Mexico remittance volume; the source does not say that share is handled with stablecoins. The companies describe both dollar stablecoins as compliant with the U.S. GENIUS Act.
