Send to a wallet

Sending supported dollar tokens to another wallet is one of the main things you can do with Arca. The recipient needs a valid EVM address and must support the token and network you choose.

Before you start

You need two things:

A balance in your wallet. Tap Buy first if you are at $0.
The recipient’s wallet address, or a QR code they can show you. A wallet address is a long string starting with 0x. Many wallet apps (including Arca) let you share yours with one tap.

On the Wallet tab, tap Send. A small sheet appears with two options:

Withdraw to bank account — Transfer dollars to your bank account, Cashapp etc.
Send to a wallet — Send dollars to an EVM-compatible wallet address.

Pick Send to a wallet.

Step 2: Pick the network and token

The app opens a token picker. Tap the network (Base, Optimism, or Arbitrum), then pick USDC or USDT from that network’s token list.

Ask the recipient which network they support. This is the single most important thing to get right. If you send USDC on Base to a wallet or app that only watches Optimism, the dollars can be lost. Many wallets support several EVM networks, but always check first. The warning on your Receive screen says the same thing: only send to supported networks.

If you are sending to another Arca user, they can receive supported dollar tokens on Base, Optimism, and Arbitrum.

Step 3: Enter the amount and recipient

The Send screen has the amount at the top, then the token, recipient field, and fee details below it. Type the dollar amount you want to send.

Then fill in the recipient. You have three ways to do that:

Type or paste — tap the input field and paste the address from your clipboard, or type it. There is a paste icon on the right side of the field.
Address Book — tap the Address Book button to pick a contact you have saved before.
QR Code — tap the QR Code button to open the scanner. Point it at a QR code the recipient is showing you.

The app checks that the address and amount look valid before letting you continue. If something is off, it tells you right away.

Below the recipient tools is Fee details, with the selected network and the current transfer fee. Tap the info icon beside Fee if you want to read how Arca calculates it.

Tap Review.

Step 4: Confirm the details

The Review Details sheet shows everything in one card:

To — the recipient address, shortened.
Amount — how much you are sending and which token.
Network — Base, Optimism, or Arbitrum.
Fee — the transfer fee.
Total amount — the full amount that will come out of your wallet.

Double-check the address and the amount. Transfers cannot be reversed once they go through, so take a second to confirm.

Tap Send USDC or Send USDT. While the transaction is being sent, the button shows the sending state.

Step 5: See the status

After you confirm, a status sheet appears:

Pending transaction — the transfer is being sent. You can close the sheet and keep using the app. You will get a notification when the status changes.
Transaction successful — the transfer went through. You see the amount and the recipient.
Transaction failed — something went wrong. No funds were taken. Try again.

Completed transfers also show up in Activity with a timestamp and full details.

Tips

Send a small test first when moving a large amount to a new destination. Wait for it to arrive, then send the rest.
Save the address in your Address Book if you will use it again. See the Save contacts in Address Book guide.
Check the network twice. It is the easiest mistake to avoid and the hardest to recover from.
