Pros and cons
Keystone
Pros
- Self-custody, so keys never leave the holder.
- Open source firmware that anyone can read.
- Security handled by 3 secure element chips.
Cons
- The $149 price sits well above $79.
- Support runs on email, help centre and community, with no chat or phone listed.
- Only 100% of wallets on the site are hardware.
OneKey
Pros
- Custody sits with you: self custody keeps the balance and the keys off any operator's books, unlike bynex, whose custody is custodial.
- The signing chip is a EAL 6+ secure element, a stated security rating rather than a marketing line.
- Coverage of 30,000 coins is the strongest part of the offer, and the app lists self-custody among its features.
Cons
- Support runs on email, chat and help centre only, so written channels carry the whole help load.
- On price, OneKey ranks 103 of 120 brands, so the device is not the cheapest option on the page.
- The range $79 to $278 is wide, so the higher specification device costs far more than the entry model.

Questions about each
Keystone
What does a Keystone hardware wallet cost?+
The device is priced at $149, a one off purchase. As a hardware wallet it keeps working offline, with no subscription attached to holding. A Trezor device sits at $79, so Keystone asks for more at the checkout.
Who holds the coins on Keystone?+
Custody is self custody, so the keys stay with the holder and never sit with a company. If the device is lost, recovery depends on the backup, and the options listed are seed and shamir. Nothing sits with a third party to claim back.
OneKey
How much does a OneKey device cost?+
Devices are priced at $79 to $278, a range covering the entry model and the higher specification hardware in the same line. That figure is the cost of entry and there is no tier beyond it for extra accounts or extra services. It matters most for anyone planning to hold a wide set of coins, because coverage on the scale of 30,000 is where the money goes.
Who holds the crypto in a OneKey wallet?+
You do. The design runs on self custody, and the companion app lists self custody among its features. Nothing is deposited with an operator the way a custodial platform holds a balance, which is the main structural difference from an exchange account. The other side of that is that recovery is your job too, since nobody else holds a copy of the phrase.
