About the app

Synapse provides the app experience: bridge routes, supported assets, source and destination networks, fees, and transaction status.

Synapse 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.

  • Synapse 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 Synapse works with Arca

Synapse provides bridge routes for supported assets across supported networks. Synapse controls route availability, bridge fees, timing, and transfer status. Arca can be used for the WalletConnect and signing steps when the selected route is compatible. Confirm the source network, destination network, token, recipient, and amount before approving any bridge transaction.

Frequently asked questions

Is Synapse part of Arca?

No. Synapse 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 Synapse?

Synapse accepts USDC or USDT on Ethereum, Polygon, Optimism, Arbitrum, Avalanche and BNB Chain. Always match what the Synapse checkout shows before you send from Arca.

How do I connect Arca to Synapse?

On Synapse, 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.
