Receive dollars | Arca Docs

Receiving dollars is the easiest thing Arca does. You share your wallet address with the sender, and the dollars land in your wallet when they send. No approval on your side, no forms, no forwarding.

Open the Receive screen

On the Wallet tab, tap Receive (the second of the three buttons under your balance). The Receive screen opens.

What the screen shows

After the network reminder, Arca shows your wallet QR code, your 0x wallet address, and two buttons:

Copy — copies the address to your phone’s clipboard.
Share — opens your phone’s share menu so you can send the address through a message, email, or any app.

Below that is a second card labeled Supported Networks and Supported Tokens. Each is shown as a row of badges.

At the bottom is an amber warning: Only send tokens to supported networks. Tokens sent to the wrong network may be lost permanently. Always check before sending.

You have a few ways to give someone what they need to send you dollars.

Copy and paste. Tap Copy, switch to your messaging app, and paste. Works for every app.
Share sheet. Tap Share, pick an app, and send. Fastest way to reach someone on iMessage, WhatsApp, Telegram, Signal, or email.
Show the QR code. In person, just show the screen. The other wallet’s scanner reads it and fills in your address automatically.

Supported networks and tokens

Arca supports Base, Optimism, and Arbitrum for receiving supported dollar tokens. Your wallet address is the same on those networks, but the sender still needs to choose a supported network and token.

Arca supports two digital dollar tokens: USDC (issued by Circle) and USDT (issued by Tether). Both are pegged one-to-one with the US dollar and backed by the companies that issue them. They appear in your balance as dollars either way.

Tell the sender which network you want

If the sender is using another wallet app, ask them which network they plan to use. Base, Optimism, and Arbitrum are common EVM networks, but support varies by wallet and exchange.

If the sender is on Arca, they will see a prompt to pick a network on the send side, and either choice lands in your wallet.

Getting dollars from an exchange

If someone is sending from an exchange (Coinbase, Binance, Kraken, and similar):

Copy your Arca wallet address.
On the exchange, start a withdrawal of USDC or USDT.
Paste your Arca address as the destination.
Pick Base, Optimism, or Arbitrum as the network. Not every exchange supports all three, so pick whichever supported network the exchange offers.
Confirm the withdrawal.

Your dollars arrive in Arca once the exchange sends the transfer, which can be instant or a few minutes depending on the exchange.

What happens when dollars arrive

Your Wallet balance updates after the app refreshes, usually within the refresh cycle. You can pull to refresh if the transfer does not appear yet. If push notifications are enabled and delivered while the app is in the background, you may receive one. The transfer appears in Activity with the sender address, amount, and network.

You do not have to accept, approve, or confirm anything. Incoming dollars are yours the moment they arrive.

The one thing to avoid

Never give your Arca address as a destination for a different token, such as Bitcoin, or for an unsupported network. Funds sent with the wrong token or network may be lost. The warning on the Receive screen is there to remind you every time.

If you are unsure what network the sender is using, ask before they send. A one-line question is cheaper than a mistake.
