Walmart Steps Into Crypto Banking With OnePay’s Bitcoin and Ethereum Trading

Walmart, the world’s largest retailer, is once again signaling its growing interest in blockchain technology. Its financial technology subsidiary, OnePay, is reportedly preparing to integrate Bitcoin and Ethereum trading into its mobile banking app by the end of this year, according to sources cited by CNBC.

The move positions Walmart more directly in the evolving landscape of digital assets. OnePay, created in 2021 through a partnership with investment firm Ribbit Capital, has already attracted millions of users with a range of services that include a high-yield savings account, a debit card, and a rewards-integrated digital wallet. Now, the platform appears ready to broaden its offerings into crypto, a sector increasingly viewed as a mainstream component of modern banking.

The trading infrastructure will reportedly be powered by Zerohash, a Chicago-based startup specializing in stablecoin and crypto custody solutions. Zerohash, which recently achieved “unicorn” status after a $104 million funding round led by Interactive Brokers, declined to comment on the partnership. However, its existing infrastructure has been widely adopted by fintechs looking to bridge traditional financial services with digital asset markets.

CNBC reporter Hugh Son suggested the development marks a pivotal step for legacy companies entering the space: “Crypto is increasingly seen as a core offering that exists alongside traditional banking services like savings accounts, credit cards, and wealth management,” he said during an interview on the network’sSquawk on the Street.

OnePay’s mobile app has gained momentum in recent months. Originally released in 2020, the platform has surged into the top five free finance apps across both Apple’s App Store and Google Play. In app rankings, it has jumped more than 50 spots in each store, now sitting at #58 on iOS and #73 on Android. The surge suggests growing consumer appetite for digital-first financial products, a trend accelerated by the integration of crypto functionality.

This is not the first time Walmart has been linked to the cryptocurrency sector in 2025. In June, aWall Street Journalreport suggested the retailer was considering launching its own stablecoin—a claim that drew sharp criticism from Senator Elizabeth Warren, who has long voiced skepticism about corporate involvement in digital currencies.

For Walmart, however, the potential benefits are clear. By embedding crypto trading within OnePay, the company positions itself to capture both younger demographics and tech-savvy consumers already active in digital finance. It also provides a competitive edge against other retail banks and fintech challengers racing to expand their digital asset services.

While details remain limited—particularly on whether additional tokens or DeFi features will be included—the timing highlights Walmart’s ambition to remain relevant as financial technology continues to evolve. If the rollout proves successful, OnePay could emerge not only as a top-tier mobile banking platform but also as a significant entry point for mainstream cryptocurrency adoption in the United States.
