Cross-border payments startup XREX has secured $18.75 million from Tether to expand the use cases for USDT-based payments in emerging markets. Founded by Wayne Huang and Winston Hsiao, XREX aims to double down on stablecoin cross-border business-to-business (B2B) payments. The Taipei-based company plans to use the funds to facilitate compliant, USDT-based cross-border B2B payments in emerging markets, offering businesses greater ease, efficiency, and potentially lower costs. Additionally, XREX will collaborate with the Unitas Foundation to launch XAU1, a stablecoin backed by Tether Gold (XAUt), providing a hedge against inflation.
