Cash App USDC: Send and Receive Stablecoins with Senddy

Cash App USDC transfers let you move dollars between Cash App and a private Senddy balance in about a minute, on any of four networks. This guide shows both directions, the cheapest network, and the limits to know.

USDC is a stablecoin: a digital token that stays worth one US dollar. Senddy is a private payments app where you hold USDC in a private balance on Base that earns yield. Relay is the bridge Senddy uses to move USDC between networks.

What Cash App USDC does

Cash App lets you send and receive USDC like a payment, but it never holds USDC for you. Received USDC converts instantly to dollars in your Cash Balance. When you send, Cash App converts dollars 1:1 to USDC.

As of October 2026, the details from Cash App's stablecoin help page are:

Networks: Solana, Ethereum, Polygon and Arbitrum.

Fees: Cash App charges no fees for stablecoin transfers.

Verification: You need to verify your identity.

Availability: Not available in New York or for sponsored accounts.

Irreversible: If you use the wrong address or network, the money can be lost permanently.

Because Cash App has no stablecoin balance, USDC won't sit in Cash App earning anything. That's where Senddy fits. Your private Senddy balance earns yield, and Cash App stays your spending account.

Which network to use

Use Solana for almost everything, because it is the cheapest route in both directions and a Solana address can't be mistaken for an address on another network.

Senddy bridges USDC through Relay. These are typical costs at time of writing, from live Relay quotes in October 2026. They show the share of the amount lost on a $100 and a $1,000 transfer:

Quotes move with network conditions, so treat these as a guide. Ethereum costs much more on small amounts.

Use the same network on both sides. Pick it in Senddy, then send from Cash App to the address Senddy gives you for that network.

Deposit: Cash App to Senddy

To deposit, copy a Senddy deposit address for your chosen network, then send USDC to it from Cash App. The money lands in your private balance, usually within a minute.

1.In Senddy, tap Deposit, then Stablecoin Deposit.

2.Under Send from, choose Solana (or Polygon or Arbitrum).

3.Copy the address. It's reusable: every deposit to it lands in your balance.

4.In Cash App, open the Payments tab ($) and enter at least $1.

5.Tap Pay, paste the Senddy address, and tap Send.

You can also scan a wallet QR code from the icon at the top left of the Cash App home screen. If you send on Ethereum, Polygon or Arbitrum instead of Solana, make sure Cash App sends on the same network you picked in Senddy.

Once it arrives, the money goes straight into your private balance and starts earning yield. See Bridging between networks and Deposits and withdrawals.

Be honest about privacy here. The transfer from Cash App to Senddy is public onchain, and Cash App keeps its own records. Privacy applies once your money is in the Senddy balance. See how to send money anonymously for how that works.

Withdraw: Senddy to Cash App

To withdraw, copy your Cash App stablecoin address, paste it into Senddy's Send screen, and pick the matching network. Cash App then turns the USDC into dollars in your Cash Balance.

1.In Cash App, go to the Money tab and tap Deposit stablecoins.

2.Select the network, Solana is the cheapest, then copy the address or share the QR code.

3.In Senddy, tap Send and paste the address.

4.For a 0x address, choose its network. A Solana address is detected automatically.

5.Review and confirm.

It usually takes about a minute. Withdrawals to other networks have a minimum of 1 USDC.

Copy the address fresh from Cash App each time. A wrong address or network can't be undone.

If you want to move money on to Venmo, the route is Cash App to Senddy, then Senddy to Venmo. See how to transfer money from Cash App to Venmo and Venmo crypto and PYUSD with Senddy.

Fees, limits and timing

Cash App charges nothing for stablecoin transfers, so your costs are the bridge spread and Senddy's own fee. Timing is about a minute each way.

As of October 2026:

Cash App fees: None for stablecoin transfers.

Sending limits: $2,000 per day and $5,000 per week, with identity verification.

Receiving limit: $10,000 per week. Accounts under 90 days old may have a lower receiving limit.

Minimum: At least $1 to send from Cash App. Senddy needs 1 USDC for withdrawals to other networks.

Bridge cost: See the table above. Solana is typically 0.04% on $100.

Senddy fee: Plus Senddy's fee, see Pricing.

Check Cash App's help page for current limits before you move a large amount. Send a small test first if it's your first time.
