Our verdict

MetaMask is a browser wallet that puts your keys in your own hands through self-custody, with a typical listed price of €0. It suits people who want a low-cost way to hold their own crypto, while anyone needing a phone app or a hardware device would be better served by VaultLeap or Trezor.

Pros and cons

Pros

  • Self-custody by design: self custody keeps the keys with you, and only 46% of the wallets in the category work this way.
  • Typical listed price of €0, with a typical listing supporting 46 coins.
  • Support runs on email, chat and help centre, so help is available in several formats.
  • Backed by Consensys Software Inc., working on the wallet since 2016.

Cons

  • Not open source, so the code that holds your keys cannot be read before you install it.
  • Browser only, so security rests on browser software rather than a hardware device.
  • Support runs on email, chat and help centre only, with no phone line among them.

Who it suits

  • People who want self custody and will store a seed phrase themselves.
  • Users happy to manage their wallet from a browser setup rather than an app on a handset.
  • Holders who are comfortable with written and community help rather than phone support.

Who should look elsewhere

  • People who want a phone app: VaultLeap is mobile rather than browser.
  • Anyone who wants keys held in a physical device: Trezor is hardware.
  • Anyone who needs a phone line for support: help comes through email, chat and help centre.

Safety of your money

MetaMask runs on self custody, so the keys sit on the device you control and no provider holds them. That removes custodial risk and puts the whole job on you, including keeping the recovery phrase safe. The codebase is not open source, so it cannot be read before you install it. Wallets that work this way are 46% of the listings in the category.

Who runs it

MetaMask is run by Consensys Software Inc., which has worked on the wallet since 2016. A named company with that length of history gives some reassurance that maintenance will continue. Support runs on email, chat and help centre, so help comes through email, chat, a help centre and the community rather than a phone line. The terms of use sit with the same company.

How MetaMask compares

Frequently asked questions

How much does MetaMask cost?+

A typical listing shows a price of €0 for the wallet itself, and paid listings do appear, reaching €876.09. The download is the cheap part of using MetaMask. What the wallet does not do is hold money for you: self custody means the keys and the balance stay under your own control.

Is my money safe in MetaMask?+

MetaMask is a self custody wallet, so your keys live on your own device instead of with a provider, and 46% of the wallets here work that way. The trade-off is responsibility, since nobody on the provider side can recover the funds. The codebase is not open source, so it cannot be read before you install.

How do I recover a wallet if the device is lost?+

Recovery rests on a seed phrase, the backup method recorded for MetaMask, and 84.2% of the wallets in the category work the same way. Because the wallet is self custody, nobody can reset access from the provider side. Keep that phrase secure, as it is the only copy that matters.

What platforms does MetaMask run on?+

MetaMask is a browser wallet, so it lives in the browser on the device you already use. There is no phone app of its own, and mobile and mobile are the mobile options in the comparison while hardware is the hardware choice. Browser storage is convenient, but it ties your keys to the browser.

How much support do I get?+

Support runs on email, chat and help centre, which covers email, chat, a help centre and community channels. There is no phone line among them, so a stuck transaction is handled in writing or in public. The help centre and the community forums are where most questions get answered.

Who is behind MetaMask?+

MetaMask is operated by Consensys Software Inc., which has worked on the wallet since 2016. The terms of use sit with that same company, and support is handled by the same operation through email, chat and help centre. Because the wallet is self custody, responsibility for the balance sits with you rather than with the operator.

What are the risks of holding crypto?+

Prices in this market can fall hard, and retail losses run at 70.15% across the category. A self-custody wallet such as MetaMask, which uses self custody, keeps keys out of a provider's hands but does not protect the value of what you hold. A secure seed phrase is the practical safeguard.
