MoonPay adds Cash App Pay for MetaMask purchases, letting 57M+ Cash App users buy a wide range of digital assets directly into self-custody wallets without card details.
MoonPay has added Cash App Pay as a payment option for buying digital assets, and it’s now live inside MetaMask for eligible US customers. The integration lets users tap their Cash App balance at checkout to fund crypto purchases directly into self-custody wallets, skipping the usual friction of entering card numbers or logging into separate accounts.
MoonPay said it’s the first platform to offer Cash App Pay for digital asset transactions. Cash App carries roughly 57 to 59 million monthly active users. That’s a large pool of potential new crypto buyers who just got a simpler on-ramp.
Until now, Cash App users who wanted to buy crypto through the app were limited to Bitcoin and USDC. This MoonPay integration changes that. Cash App balances can now be used to acquire a much wider array of digital assets. Those assets land in self-custody wallets like MetaMask and Trust Wallet, meaning users maintain direct control of their funds.
No additional logins. No card details to fumble through. Users select Cash App Pay at checkout, confirm the transaction, and the funds move from their Cash App balance into whatever token they’re purchasing.
Cash App Pay joins a roster of payment methods MoonPay already supports, including PayPal and Venmo.
Cash App’s user base is significant. Many of those users are already comfortable with digital payments and peer-to-peer transfers but may have never ventured beyond Cash App’s native Bitcoin buying feature. Removing the payment barrier lowers the threshold for first-time crypto buyers considerably.
The self-custody angle matters. Platforms like Coinbase and Robinhood let users buy crypto easily enough, but the assets typically sit in custodial accounts. This integration funnels purchases directly into wallets where the user holds the keys.
MetaMask’s decision to surface Cash App Pay through MoonPay suggests the wallet is prioritizing accessibility for US users. Cash App is already a licensed, regulated money services business, meaning this integration requires no additional regulatory gymnastics.
For Cash App parent company Block (formerly Square), the move extends its crypto footprint without requiring Block to build additional infrastructure. Cash App Pay simply becomes another rail that third parties can plug into.
