Our verdict on each
OneKey
OneKey is a self-custody hardware wallet for anyone who wants their own keys and broad coin coverage at a device price rather than a subscription. It scores 6.3 overall, with the offer carrying the weight and the cost side resting on what you pay for the device.
Tangem
Tangem suits anyone who wants a physical card that keeps spending and saving in their own hands, at $59.90 to $180. It serves long-term holders who want a wide coin list inside self-custody, and suits less well people who need exchange features or phone support.

Pros and cons
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.
Tangem
Pros
- Tangem guards keys with a EAL6+ certified Samsung Semiconductor secure element, putting the important part in dedicated hardware rather than phone software.
- The coin list of 14,100 puts the card at position 7 of 108 on coins supported.
- Custody sits with the holder through self custody, and the software is published as open source for anyone to read.
Cons
- Support runs on email, chat and help centre only, so there is no phone line in the list.
- Recovery runs on a seed phrase, listed as seed, which means the phrase itself carries the full balance.
- Connectivity is nfc only, so a phone has to be on hand for every use.
Who each suits
OneKey
Who it suits
- Long term holders who want their keys offline and their coin list long.
- Buyers who read code, since the firmware and app are open source.
- Shoppers comparing hardware who want the entry price to sit at $79.
Who should look elsewhere
- Bit2Me, whose wallet is mobile, if a phone suits you better than a device you own.
- bynex, where custody is custodial, if you would rather an operator held the keys.
- Trezor, if you would rather pay one fixed $79 than choose a model across $79 to $278.
Tangem
Who it suits
- Long-term holders who want to keep rather than trade, with self custody leaving the keys with you and 14,100 covering the long tail of assets.
- People who want card-style access to crypto without handing over a seed, since connectivity is nfc and a tap is the whole routine.
- Readers who care about chip level security, because the EAL6+ certified Samsung Semiconductor secure element is the part that does the guarding.
Who should look elsewhere
- Anyone wanting an app first account: Bit2Me is a mobile wallet, where Tangem is a card held in hand.
- Holders who prefer a provider to look after the assets: bynex runs on custodial, the opposite of the self custody model here.
- Buyers chasing the cheapest hardware device: Trezor lists at $79, under the upper end of the $59.90 to $180 range.

Questions about each
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.
Tangem
How much does a Tangem cost?+
Prices run $59.90 to $180 across the card range, and the purchase is a device rather than a plan tied to a platform balance. The entry card sits under the €69.28 median of the hardware wallets we rank, while the upper end of the range goes past the €159.76 mark most of them sit under.
Do I hold my own crypto?+
Tangem runs on self custody, so keys are created and kept on the card rather than on an account that someone else controls. Nothing needs to be held on your behalf, and the card never becomes a claim on a platform balance. Software is published as open source, so the app and firmware can be read rather than trusted.
