Our verdict on each
MetaMask
MetaMask suits anyone who wants a free browser wallet that keeps control of their own keys, with self-custody (self custody) and a seed backup (seed) as the trade-off for convenience. It suits everyday token holding, not larger balances that need a separate device.
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.

Pros and cons
MetaMask
Pros
- Self-custody, so the keys stay with the holder (self custody)
- Help runs through email, chat and help centre
- Operated by a named company, Consensys Software Inc.
Cons
- MetaMask is not open source, so the code cannot be read by the people running it
- A browser wallet (browser) keeps the work on the same device you browse with, so Trezor's hardware approach (hardware) is the calmer choice for larger balances
- Recovery depends on a seed phrase (seed) held by the holder
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
MetaMask
Who it suits
- People who want to hold their own keys without buying a device
- Readers who want their wallet open in a browser tab rather than an app
- Anyone comfortable storing a seed phrase (seed) somewhere safe
Who should look elsewhere
- Trezor, if you would rather keep the keys in a hardware device (hardware)
- Bit2Me, if a mobile wallet (mobile) suits you better
- bynex, if you would rather the provider held the keys (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
MetaMask
Does MetaMask hold my coins for me?+
MetaMask is a self-custody wallet (self custody), and self-custody is also listed as a headline feature (self custody). The keys stay on your side rather than with a provider, so no account balance sits with the company, and recovery after losing the device is down to your own backup.
How do I back up a MetaMask wallet?+
The listed backup method is a seed (seed), a single set of words you write down and keep offline. Anyone planning to use self-custody needs a safe place to store that phrase, and looking after it is the holder's job rather than something a provider handles on your behalf.
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.
