Our verdict

OneKey suits people who want broad coin coverage in an open-source, self-custody hardware wallet. It supports 30,000, while the device costs $79 to $278. You remain responsible for protecting the seed backup, so it is better suited to users comfortable managing wallet security than those wanting simple mobile access.

Frequently asked questions

How much does a OneKey hardware wallet cost?+

OneKey hardware wallets cost $79 to $278. This is a device purchase rather than a subscription, and the exact amount depends on the model you choose. Mobile alternatives may suit buyers with a smaller budget.

How many coins can OneKey support?+

OneKey supports 30,000. That gives it broad coverage across different crypto assets and puts it high in the available coin-support ranking. Always confirm that your intended assets are supported before buying.

Can I control my own crypto?+

Yes. OneKey provides self custody, meaning the user controls the wallet rather than relying on a custodian. That also makes secure device handling and backup management important parts of using the product.

Is OneKey open source?+

Yes, OneKey is open source. Its wallet also uses an EAL 6+ secure element on the Pro product. Open-source software and dedicated wallet hardware give users tools to inspect and secure their crypto setup.

How do I back up my OneKey wallet?+

The stated backup option is seed. Because this is self-custody, the user is responsible for safeguarding the seed safely. Anyone who obtains it may be able to control the funds, so it should not be exposed carelessly.
