Walmart will soon accept cryptocurrency payments in Bitcoin (BTC), Ethereum (ETH), and XRP through its OnePay Cash app. This new feature, expected to launch later this year, will enable users to buy, sell, and hold cryptocurrencies, thanks to a partnership with ZeroHash. The integration will be available both in the OnePay mobile app and in-store checkout systems, potentially reaching Walmart's 150 million weekly shoppers. OnePay, majority-owned by Walmart, currently ranks fifth among free finance apps on Apple's App Store.
