Buy Crypto with Cash App
You can buy crypto with Cash App on Peer. Select an offer, send a standard Cash App payment to the seller's $Cashtag, and Peer verifies it with a zero-knowledge proof. USDC is released from onchain escrow directly to your own wallet — you're not limited to the bitcoin Cash App sells in-app, and the crypto isn't held for you by an app.
How to buy crypto with Cash App
Choose a Cash App offer
Open the Peer app, enter the amount of USDC you want, and select an offer that accepts Cash App. Offers are denominated in USD.
Pay the seller's $Cashtag
Send the exact quoted USD amount in a single Cash App payment to the seller's Cashtag.
Verify with a zero-knowledge proof
Peer generates a zero-knowledge proof of your Cash App payment — confirming amount, recipient, and timestamp without exposing your account activity.
Receive USDC in your wallet
After verification, escrow releases USDC to your wallet on Base. Bridge to Solana, Hyperliquid, Ethereum, and 20+ other chains if you want it elsewhere.

Cash App FAQs
Can I buy crypto with Cash App?
Yes. On Peer you buy USDC from another person and pay their $Cashtag with a regular Cash App payment. A zero-knowledge proof verifies the payment, then onchain escrow releases the crypto to your wallet, typically in 2-5 minutes.
How is this different from buying bitcoin inside Cash App?
Cash App sells bitcoin that lives inside your Cash App account. On Peer, you buy USDC peer-to-peer and it is released directly to a wallet you control on Base — non-custodial, and bridgeable to 20+ chains.
Which currencies does Cash App support on Peer?
Cash App offers on Peer are denominated in USD. For EUR, GBP, and other currencies, use Revolut, Wise, or PayPal offers instead.
Does buying crypto with Cash App require identity verification?
No additional verification is required on Peer. You connect a wallet and pay with the Cash App account you already have; zero-knowledge proofs keep your payment data private.
What is a $Cashtag and where do I send the payment?
A Cashtag is Cash App's unique username. The Peer app shows you the seller's Cashtag (or a QR code) at payment time — send the exact quoted amount to it in a single payment.
