Network

The network this app runs on, and what your wallet needs.

RealTime Exchange runs on one live network, Arc Testnet. The app is built for it and will ask you to switch if your wallet is elsewhere. Trading on Arc Mainnet is coming soon. Switch the tab below to see its details as they are published.

Adding the network to your wallet

If your wallet is on another network when you connect, the app shows a Switch Network step. Press the switch button and approve the request in your wallet. For most wallets this also adds the network if it is missing, so you normally don't have to enter anything by hand.

Signing in with the built-in wallet sign-in sets up the network for you.
