Hi

Please assign me this task. I’ll implement network detection for the connected Stellar wallet, compare it against the app’s supported network, and show a clear warning banner when there’s a mismatch. I’ll also ensure unsafe trading actions are disabled while keeping read-only browsing available, and add any necessary tests/docs for validation.

ETA: 1–2 hours
