### Advanced routing

Choose connection behavior separately for each part of Oxygen Atmos:

| Area                 | Traffic                                                                                                             | Priority behavior                                                     |
| -------------------- | ------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------- |
| **Oxygen API**       | Login, subscription checks, token lists, browser components, application updates, and other Oxygen service requests | Uses the selected connection route                                    |
| **Wallet RPC**       | Blockchain network requests from wallets                                                                            | A wallet or linked browser profile proxy is used first when available |
| **Portfolio data**   | Balance, portfolio, and token information                                                                           | Uses the selected connection route                                    |
| **CEX accounts**     | Exchange account requests                                                                                           | The proxy assigned to the exchange account always has priority        |
| **Browser profiles** | Browser profile traffic                                                                                             | Always uses the proxy saved in the profile                            |

<Note>
  Connection settings do not replace browser profile proxies. Each browser profile continues to use its own saved proxy.
