How to Send and Receive Stablecoins in Cash App on Polygon

tl;dr

• Cash App has added stablecoin payments on Polygon
• Users send and receive USDC over Polygon directly from their Cash Balance
• 58 million monthly active Cash App users 
• No separate stablecoin wallet or balance, no fees
• USDC received converts to dollars instantly; dollars sent convert 1:1 to USDC
• Cash App joins Revolut, Stripe, Visa, Modern Treasury, and a growing list of fintechs and institutions running money on Polygon, part of the Open Money Stack

Cash App, the consumer banking app from Block with 58 million monthly active users, has launched stablecoin payments on Polygon. Users can send and receive USDC over Polygon directly from their Cash Balance. There are no fees and USDC that arrives converts to dollars instantly. Dollars sent leave as USDC at a 1:1 rate.

The integration is built for the way people actually use Cash App. That means no separate stablecoin wallet to fund and no extra step to swap. 

A user gets one Polygon address that can receive stablecoins, and one Cash Balance that holds dollars. Polygon’s Open Money Stack tech runs beneath the surface

In the Cash App, users can:

• Send USDC over Polygon: Pay any compatible wallet address by entering a dollar amount. Cash App converts the dollars 1:1 to USDC at send. No fees.
• Receive USDC over Polygon: Share a Polygon address or QR code from the Money tab. Incoming USDC lands as dollars in the Cash Balance instantly.
• Move money without juggling: No separate stablecoin balance, no manual conversion, no extra step. The dollar balance is the stablecoin balance.

Cash App also supports USDC on Solana, Ethereum, and Arbitrum.

How to send USDC on Polygon from Cash App

1. Open the Payments tab ($).
2. Enter at least $1.
3. Tap Pay.
4. Paste the recipient's wallet address. Or tap the icon at the top-left of the home screen to scan their QR code.
5. Confirm by tapping Send. Cash App converts the dollars 1:1 to USDC and routes the payment over Polygon. No fees.

How to receive USDC on Polygon in Cash App

1. Open the Money tab.
2. Tap Deposit stablecoins.
3. Select Polygon to view your wallet address.
4. Share the wallet address or QR code with the sender.
5. When USDC arrives, it converts to dollars in your Cash Balance instantly.

Stablecoin send limits are $2,000 per day and $5,000 per week; receive limits are $10,000 per week. Stablecoins are not currently available to Cash App users in New York.

Cash App joins the Open Money Stack on Polygon

Cash App's launch puts another large consumer fintech on the same Polygon rails that already carry billions in volume for institutions and payments companies. 

Recent integrations include:

• Revolut, where users have moved more than $1.3B in cumulative volume over Polygon for stablecoin transfers, payments, trading, and POL staking
• Stripe, supporting Meta's USDC creator payouts on Polygon, rolling out across 160+ countries
• Visa, supporting Polygon on its global stablecoin settlement program
• Modern Treasury, integrating Polygon for programmatic USD-to-USDC conversion and stablecoin payment orchestration alongside ACH, wires, RTP, and FedNow
• DeCard, enabling USDC and USDT0 payments at 150 million+ merchants globally on Polygon
• Deel, enabling stablecoin salary payments to global contractors on Polygon
• Toku, running more than $1B in annual stablecoin payroll volume on Polygon
• Mastercard and Mercuryo, bringing verified usernames to self-custody wallets
• Flutterwave, Africa's leading cross-border payments infrastructure, selecting Polygon as the default chain
• Plus WorldPay, Reliance Jio, NRW.BANK and Cashlink, BlackRock and Securitize, and others integrating payments and real-world assets on Polygon

These integrations all run on Polygon, which is the settlement layer for the Open Money Stack (OMS), Polygon's open infrastructure for global money movement. OMS pulls the Polygon chain, wallets, cross-chain orchestration, blockchain-building infrastructure, and ramps (via Coinme, pending regulatory approval) into one API institutions can build on without locking themselves into a closed vendor.

Polygon's payments-focused upgrade path keeps compounding. Recent upgrades are optimized for payments: eliminating reorgs, bringing finality under five seconds, and pushing throughput past 3,800 transactions per second with 1.75-second block times, with fees a fraction of a penny.

For a Cash App user, this is invisible. They see one balance and one address. Beneath the surface is an open rail that already moves money for tens of millions of people across the world's largest consumer fintechs.

Cash App on Polygon is a step toward that being the default: stablecoin payments that feel like dollars, on rails that institutions choose because they are open.
