Gamified shopping loyalty platform StormX will now let its users earn cashback in cryptocurrencies when shopping at Walmart.

According to an announcement shared with Cointelegraph on August 14, StormX users can now earn up to 4% cashback in crypto for purchases made at Walmart. Users who achieve a “Diamond” rank can earn up to 14%. StormX CEO Simon Yu said that he believes this Walmart partnership will bring new users to the service:

“As the only crypto cashback program for Walmart worldwide, we are confident that users will take advantage of the rewards program to earn their favorite cryptocurrency while shopping at their favorite retailer.”

Per the announcement, Walmart is the latest addition to StormX’s pool of more than 650 partners, which already includes outlets like Microsoft, eBay, Nike, Adidas, Target, Dell and Samsung. StormX says it has already distributed more than $2 million to its users.

In June, Walmart’s Chinese subsidiary partnered with VeChain, a blockchain-based supply chain management platform, to create a system that traces food products. At the beginning of March, Walmart also joined the Hyperledger blockchain initiative.
