[Eco Bounty] ioPay Ethereum Mainnet "Add Network" Failure

Summary

When attempting to add the Ethereum Mainnet using the built-in "Add Network" list (the popular/preset networks tab), the app fails to connect and displays an error message: "RPC URL is invalid." This is a critical issue as it prevents users from using standard networks even when they are not entering custom data.

Steps to Reproduce

1. Open the ioPay app.

2. Tap the Network Selector at the top of the screen.

3. Tap the "Add Network" button.

4. Locate Ethereum Mainnet in the "Popular" or preset list.

5. Tap "Add" or "Confirm".

6. Observe the error message: "RPC URL is invalid."

Expected Result

The app should successfully connect to the default Ethereum Mainnet RPC provided by ioPay, add the network to the user's list, and allow them to switch to it.

Actual Result

The app rejects its own default settings for the Ethereum Mainnet, flagging the pre-configured RPC URL as "invalid."
