Pros and cons
CoolWallet
Pros
- Keys stay with you, since custody is self custody
- A CC EAL 6+ secure element keeps the signing work inside the device
- Pairs over bluetooth, so no cable is needed
Cons
- The hardware price runs higher than the Trezor model at $79
- Support runs on email and help centre only
- The range of coins supported is narrower than the hardware-wallet median of 345
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.
Who each suits
CoolWallet
Who it suits
- Holders who want custody of keys on their own device
- People who already back up a seed phrase and can keep it safe
- Smartphone users who prefer signing over Bluetooth to a cable
Who should look elsewhere
- Buyers set on the lowest hardware price, since Trezor lists $79
- Anyone wanting a mobile wallet app, since Bit2Me is a mobile wallet
- People who want a provider to hold the coins, as bynex is custodial
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.
Questions about each
CoolWallet
How much does a CoolWallet cost?+
CoolWallet is a hardware wallet, so the cost is the device price of $39 to $149. There is no account or monthly charge attached to holding coins on it, and the keys stay with you. Expect to pay for the hardware once rather than per year.
Does CoolWallet hold my coins for me?+
No, custody is self custody, and self-custody also appears in the listed features under self custody. You hold the wallet and the seed phrase, so losing either one means losing access. That is the trade for keeping control.
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.
