About the app

Across provides the app experience: bridge routes, source and destination chains, fees, timing estimates, supported assets, and transfer status.

Across uses WalletConnect for wallet connection, approvals, or onchain actions. Arca is the wallet review layer; check the token, network, amount, and destination before you approve or send.

  • Across handles its own account, product, pricing, availability, and support.
  • Arca helps with the wallet step so you can review connection, payment, or signing requests before continuing.

How Across works with Arca

Across provides cross-chain bridge routes for supported assets, including USDC routes across networks such as Ethereum, Base, Optimism, and Arbitrum where available. Across controls route selection, bridge fees, timing, and transfer status. Arca can review the wallet connection and bridge transaction before you sign. Confirm both chains, token, recipient, and amount before approving.

Frequently asked questions

Is Across part of Arca?

No. Across is a separate app with its own product, account, and support. Arca is a non-custodial wallet for digital dollars. They only work together at the wallet step you approve.

Which tokens can I use to pay Across?

Across accepts USDC or ETH or WBTC or USDT on Ethereum, Base, Optimism and Arbitrum. Always match what the Across checkout shows before you send from Arca.

How do I connect Arca to Across?

On Across, choose the connect option and pick WalletConnect. Scan the QR code with Arca, or tap the deep link to open Arca on the same phone. Arca shows a review screen before connecting so you can confirm the request came from you.

What if I send to the wrong network or address?

Always match the token, network, and address that the app shows before you send. Payments sent to the wrong place are usually difficult to recover, which is why Arca shows a full review screen and a clear amount before you confirm.
