Install only from the real origin
Add to home screen from openfidex.com. Do not install a look-alike from a text message.
If the phone UI hides the payload because the screen is small, the phone UI is unsafe.
Mobile trading UIs fail in two ways. They either shrink a desktop pit onto a postage stamp, or they delete the serious parts so the remaining buttons look like a game. OpenFidex has to pick a third: fewer panels, same legal meaning of a signature.
Use the phone to check, alert, and occasionally sign something you already understood. Do not use a bus ride and a glare-filled screen as your entire research department. The model will not save you from sunlight on a plus button.

The phone’s job is to tap you on the shoulder. It is not to finish the trade in your pocket.
A payload that needs landscape to be safe should get landscape. Pride is cheaper than a fat-finger.
The in-app mobile chrome is built so thumbs can reach work without covering the numbers that matter.
Even this public page keeps a signup bar on small screens, because that is how people actually finish a thought on a phone.
A phone is not a second custody model. If anyone tells you to “generate a mobile-only wallet they manage,” hang up.

No. OpenFidex is a non-custodial software interface. A wallet is created in your browser, you keep the keys, and you cryptographically sign every order before it reaches a third-party venue such as Hyperliquid. The software does not take custody of assets and does not submit transactions unless you sign them.
