About the app
Relay provides the app experience: bridge routes, swap routing, supported chains, fees, execution timing, and transfer status.
Relay may use WalletConnect or show direct payment details depending on the flow. Arca is the wallet review layer; check the token, network, amount, and destination before you approve or send.
- Relay 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 Relay works with Arca
Relay gives users a consumer-facing bridge and swap flow for supported assets across many networks. Relay controls route availability, fees, execution timing, and status. Depending on the flow, it may ask for a wallet connection or show payment details. Arca can help you review the token, network, route, amount, and destination before you approve or send.

Relay accepts USDC on 85+ supported networks. Always match what the Relay checkout shows before you send from Arca.
How do I connect Arca to Relay?
On Relay, 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.
How do I pay Relay with Arca?
Open Relay and copy the destination address, token, network, and amount. In Arca, tap Send, choose Send to a wallet, and enter the same details. Review everything on the confirmation screen, then send.
What if I send to the wrong network or address?
