OnePay, the fintech firm majority-owned by Walmart, right now offers cryptocurrency trading and custody on its mobile app, CNBC has learned.

OnePay now customers access bitcoin and ether later this year with help from the startup Zerohash.

By allowing OnePay users to hold bitcoin and ether in their mobile app, customers could presumably convert their crypto into cash and then use those funds to make store purchases or pay off card balances.

It now allows users 18+ to buy, sell, and hold BTC or ETH starting at $1, then convert to USD for payments at Walmart checkout via barcode or linked cards. The excitement came from a recirculated October 2025 CNBC clip about OnePay partnering with Zerohash, reaching Walmart's 150 million U.S. shoppers without changing store registers, which still process only fiat. Enthusiasts celebrated the access for everyday users, while skeptics noted the conversion steps, volatility risks, and tax implications.
