On August 7, 2018, the famous Ethereum storage MetaMask wallet software was updated to the latest version (4.9.0) and built-in support for Trezor hardware wallet.
MetaMask is an online Ethereum wallet that works as an extension for Chrome, Firefox, Opera and Brave browsers. MetaMask is also a 3.0 Web browser (DApp).
While hardware wallets like Trezor offer a very high level of security, the MetaMask team also points out disadvantages such as “you need to move money in and out (of the hardware wallet) every time you need to use DApp, perform transactions , etc. . or participate in an ICO ”and as such“ need to wait for confirmation of additional transactions and also pay additional network fees ”.
This new version of MetaMask finally supports hardware wallets, first the Trezor hardware wallet. There are also other cool new features like automatic detection of tokens in the wallet and you don't have to add them manually.
In this article, we will discuss:
Now you can connect TREZOR to your MetaMask wallet and do the following:
- check account numbers (ETH and ERC-20, ERC-721) tokens
- sign transactions (send ETH, tokens, implement contracts…)
- sign the message, which means you can login or register with Decentralized Apps (Dapps).
When a Trezor hardware wallet is linked to a MetaMask wallet, the MetaMask will appear like any other Ethereum wallet, with the difference that you need to connect to Trezor every time you need to confirm a transaction. As a result, the private key is always protected with the Trezor hardware wallet and you can be sure it will never get hacked.
Of course, you can still check your Trezor hardware wallet balance at any time, without having to log into the hardware wallet.
The MetaMask team is also working on supporting Ledger hardware portfolios in the future.
