Pros and cons
Pros

- Pairs over bluetooth, so no cable is needed
- Backup rests on a seed phrase you hold
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
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
How it compares on our data
Against the brands we track, CoolWallet ranks 61 out of 108 on coins supported and 95 out of 120 on price. That places it among the higher priced hardware wallets and towards the narrower end of coin coverage, with 35 coins against a hardware-wallet median of 345. Its overall score is 5.1, with cost at 5.6 and offer at 4.4.
How your money is protected
Custody sits with you rather than the company, since the wallet is self custody and the listed features include self custody. The device keeps a CC EAL 6+ secure element, so the signing work happens inside the hardware rather than on a phone or desktop. Recovery rests on a seed, which means the words have to be stored safely by you. No regulator or licence is listed for the company behind it, CoolBitX Ltd., based in Taiwan.

Frequently asked questions
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.
How do I connect and back up a CoolWallet?+
The device pairs over bluetooth, so there is no cable to plug in and signing happens from a paired phone. Backup rests on a seed phrase, which is the only listed recovery method. Write the words on paper, keep them away from the device, and do not photograph them.
What protects the keys inside the device?+
Signing happens inside a CC EAL 6+ secure element, which keeps the private key work on the hardware rather than on the paired phone. That is the main reason to buy hardware rather than a free app. No regulator or licence is listed for the company.
How many coins can a CoolWallet hold?+
CoolWallet supports 35 coins, against a hardware-wallet median of 345. It ranks 61 out of 108 on that measure. Anyone holding long-tail tokens should check the list first.
Who is behind CoolWallet?+
The company is CoolBitX Ltd., based in Taiwan and founded in 2014. It is a hardware maker, so there is no exchange account or bank balance to open. No regulator or licence is listed for the business.
How do I get help from CoolWallet?+
Support runs on email and help centre, so questions go by email or through the help centre. There is no phone or live chat option listed, which means a hardware fault may take a while to sort. The help centre is the faster route for setup questions.
How does the price compare with other hardware wallets?+
CoolWallet is priced at $39 to $149, and ranks 95 out of 120 on price, towards the expensive end. Trezor, for comparison, lists $79. The median hardware-wallet price is €69.28.
Is a hardware wallet the right choice for me?+
Hardware wallets are 18.8% of the wallet brands we track, and self-custody is 50.5% overall. If you are not willing to store a seed phrase, a custodial wallet such as bynex at custodial is a different trade.
