"We will continue to expand thoughtfully, prioritizing assets that meet a high bar: demand, liquidity, regulatory clarity and long-term utility." — OnePay spokesperson, per CoinCentral reporting, March 2026
Walmart-majority-owned fintech platform OnePay expanded its cryptocurrency offering from 2 to more than 15 supported assets between January and March 2026, making it one of the fastest token-listing ramps in U.S. retail fintech history. The platform, valued at an estimated $4 billion, now reports more than 3 million monthly active users and ranks No. 5 among free finance apps on Apple's App Store — ahead of JPMorgan Chase, Robinhood, and Chime.
The expansion is notable for what it represents in the crypto distribution stack: a full-service fintech app embedded at the point of sale of the world's largest retailer, which serves 150 million weekly U.S. shoppers. OnePay users can buy, sell, and hold crypto, then convert holdings to U.S. dollars in near-real-time for use at Walmart checkout — both in-store and online. All crypto services are powered by Zero Hash LLC, a $1 billion infrastructure startup that also provides backend settlement, liquidity, and custody for Morgan Stanley's E*TRADE, BlackRock, Franklin Templeton, Stripe, and Interactive Brokers.
The economic question is not whether OnePay can attract crypto-curious users — it clearly can. The question is whether a retail-embedded crypto on-ramp, targeting underbanked and crypto-naive demographics, generates sustainable fee revenue or simply subsidizes user acquisition for Walmart's broader financial services play.
OnePay's crypto rollout followed a staged cadence:
The selection criteria, according to OnePay, prioritize four factors: user demand, liquidity depth, regulatory clarity, and long-term utility. The inclusion of PAXG (a gold-backed token) and ARB (a Layer 2 scaling token) alongside meme assets like DOGE and SHIB suggests a broad-market approach rather than a curated institutional strategy.
The 90-day ramp from 2 assets to 15+ is faster than Robinhood's initial crypto expansion (which took approximately 18 months to reach comparable breadth after its 2018 launch) and rivals Cash App's multi-year token addition timeline.
OnePay is not a crypto-native app. It is a full-stack fintech platform offering:
The crypto-to-cash conversion mechanism is the distinguishing feature. Users convert crypto holdings to U.S. dollars within the app, and those funds are immediately available for Walmart purchases or can be loaded onto OnePay credit/debit cards. This creates a closed-loop system: earn, save, invest in crypto, convert to fiat, spend at Walmart.
According to Bitget reporting from March 2026, Walmart now accepts crypto payments in BTC, ETH, and XRP via OnePay Cash, with the conversion handled by Zero Hash's settlement layer. The user never touches a blockchain wallet or manages private keys.
Fee structures have not been publicly disclosed in detail. Zero Hash typically charges its enterprise clients a per-transaction fee that ranges from 0.5% to 1.5% depending on volume, according to industry estimates. Whether OnePay passes this through to users, absorbs it, or marks it up remains unclear.
Zero Hash LLC is the backend that makes OnePay's crypto services possible — and it simultaneously powers several of the largest names in traditional finance.
Funding and Valuation:
Enterprise Clients: Zero Hash provides settlement, liquidity, and custody infrastructure for Morgan Stanley (E*TRADE crypto launch planned for H1 2026), BlackRock, Franklin Templeton, Stripe, Interactive Brokers, and OnePay. This makes Zero Hash a single point of concentration in the retail crypto infrastructure stack — a fact that carries both efficiency and systemic risk implications.
The OCC charter application, if approved, would make Zero Hash a federally regulated trust bank, potentially allowing it to custody assets under a national framework rather than a patchwork of state money transmitter licenses. This would be a structural upgrade for every platform built on its rails.
OnePay enters a crowded field. The major U.S. retail fintech platforms with crypto offerings include:
| Platform | Est. Users (2026) | Crypto Assets | Crypto-to-Retail Spend | Checkout Integration | |----------|-------------------|---------------|------------------------|---------------------| | PayPal/Venmo | 438M+ (PayPal global) | 6+ | Yes (PayPal Checkout) | Wide merchant network | | Robinhood | 23M+ | 20+ | No (brokerage only) | None | | Cash App | 57M+ | BTC only | Yes (Cash Card) | Square merchants | | Coinbase | 110M+ (registered) | 250+ | Yes (Coinbase Card) | Visa network | | OnePay | 3M+ MAU | 15+ | Yes (Walmart checkout) | Walmart stores + online |
OnePay's user base is a fraction of PayPal's or Coinbase's. Its competitive advantage is physical distribution: integration at point-of-sale in 4,700+ Walmart U.S. stores. No other crypto-enabled fintech has that density of physical retail touchpoints with a single retailer.
The comparison to Cash App is instructive. Block (formerly Square) took years to expand Cash App's crypto beyond Bitcoin. OnePay reached 15 assets in 90 days — enabled by Zero Hash's multi-asset infrastructure, which handles the regulatory, liquidity, and custody complexity that would otherwise require years of internal development.
Robinhood, despite 23 million users, has no retail spending integration. Users must withdraw to a bank account before spending. OnePay's closed-loop model — buy crypto, convert to cash, spend at checkout — removes that friction, though it also means the crypto never leaves Zero Hash's custody.
OnePay was created as a separate entity from Walmart specifically to serve underbanked and unbanked populations. According to CNBC's October 2025 reporting, the platform was designed to not be limited to Walmart customers, instead targeting the broader population of Americans underserved by traditional banks.
The FDIC's most recent national survey (2021) estimated that 5.9 million U.S. households — approximately 4.5% of all households — were unbanked. An additional 18.7% were underbanked (had a bank account but also used alternative financial services). These populations disproportionately overlap with Walmart's core customer demographics.
Crypto's role in this demographic context is ambiguous. The potential benefits — access to dollar-denominated savings via stablecoins (PAXG provides gold exposure), faster peer-to-peer transfers, and lower-cost remittances — are real but unproven at scale in this user segment. The risks — volatility exposure for financially vulnerable users holding DOGE or SHIB, lack of FDIC insurance on crypto balances, and opaque fee structures — are equally real.
OnePay's inclusion of PAXG (gold-backed) alongside volatile meme tokens suggests the platform is optimizing for engagement breadth rather than financial suitability. Whether this serves or harms the underbanked users it purports to target is a question that regulators have not yet addressed in the context of retail-embedded fintech crypto.
OnePay operates in a regulatory environment that is, as of Q1 2026, more permissive than any prior period for retail crypto distribution:
The structural question is concentration risk. Zero Hash powers crypto services for OnePay, Morgan Stanley, BlackRock, and others. A service disruption, regulatory action, or solvency issue at Zero Hash would simultaneously affect crypto access for millions of users across multiple platforms. This is not hypothetical — the FTX collapse demonstrated that infrastructure concentration in crypto can produce cascading failures.
OnePay's rapid crypto expansion represents the most aggressive integration of cryptocurrency into a mass-market U.S. retail ecosystem to date. The platform's 150-million-shopper distribution footprint, combined with Zero Hash's enterprise-grade infrastructure, creates a crypto on-ramp that bypasses the friction of dedicated exchanges and brokerage accounts.
The economics remain unproven. OnePay has not disclosed crypto trading volumes, revenue contribution, or user engagement metrics for its digital asset offerings. Whether crypto drives incremental revenue or serves as a loss-leader for broader OnePay adoption — checking accounts, credit cards, BNPL — will determine the model's sustainability.
The concentration of multiple major financial institutions on Zero Hash's infrastructure stack is a development worth monitoring. In an industry that learned from FTX the cost of infrastructure dependency, the question of whether Zero Hash's regulatory upgrades (OCC charter) and institutional backing (Morgan Stanley, Interactive Brokers) provide adequate resilience is not yet answered.
What is clear: the distribution bottleneck for retail crypto in the United States has shifted from app availability to checkout integration. OnePay is the first platform to embed crypto conversion directly into the physical retail transaction layer of the country's largest retailer. Whether that produces lasting economic value — for Walmart, for users, and for the crypto ecosystem — depends on execution in a market where the Fear & Greed Index sits at 11 and Q1 2026 delivered Bitcoin's worst opening quarter since 2018.
