Risk note
Signing can authorize blockchain actions. Review transaction details before approving and reject anything unfamiliar.
Quick Answer
On-device signing means wallet approval happens on the device you control. It is a custody boundary, not a promise that every request is safe. Ondex can explain the flow and show public security context through the Ondex security model, but the final approval decision belongs to the user.
At a Glance
- Read the action, asset, destination, network, and fee before approving.
- Treat unfamiliar screens, rushed prompts, or unclear app context as a reason to stop.
- Signing is a user-controlled authorization step, not a customer-support recovery path.
What to Check Before Signing
- Confirm the action matches what you intended to do.
- Check the asset, amount, destination, network, and fee when they are shown.
- Avoid approving from screenshots, chat instructions, or pressure from another person.
- Use the backup guide before changing phones or wiping a device.
When to Stop
Stop when the transaction purpose is unclear, the destination is unfamiliar, the fee or amount does not match expectations, or the app context feels wrong. A rejected request is safer than approving something you do not understand.
FAQ
Does on-device signing make Ondex custodial?
No. On-device signing is part of a self-custody flow where approval stays with the user device. It does not move wallet control to Ondex.
Can Ondex undo a signed transaction?
Ondex can explain product behavior and safety boundaries, but it cannot reverse blockchain actions that a user approved.
Next Step
Before approving a wallet action, slow down and review the details. If the request does not match your intent, reject it and return to a trusted Ondex flow.
