An Ethereum Wallet in your Browser

Image from store MetaMask
Description from store MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser! The extension injects the Ethereum web3 API into every website's javascript context, so that dapps can read from the blockchain. MetaMask also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™), so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it. MetaMask also helps warn you when you navigate to sites that are known to have engaged in phishing, or that have names that are suspiciously similar to popular phishing targets. Because it adds functionality to the normal browser context, MetaMask requires the permission to read and write to any webpage. You can always "view the source" of MetaMask the way you do any Chrome extension, or view the source code on Github: https://github.com/MetaMask/metamask-extension Enables access to: Web 3.0 Dapps NFTs erc20 tokens ICOs erc271 ...and more!

  • (2023-05-15) K K: Awful wallet with outdated interface and new bugs appearing out of nowhere. Seems like developers got stuck in 2017. Terrible experience. The only one reason I keep using it is a support of test networks. Otherwise there are much more better extension wallets to use. For the current moment there are 2 critical bugs that prevent from using this piece of sht. Malfunction of gas estimation on Optimism chain. And random error on token approval, mm just shows error and does nothing with very "useful" advice - reload the page.
  • (2023-05-12) Artem Krotov: Looking for a replacement. Each update brings new bugs, without any useful features. Instead of fixing tons of critical bugs, the development team works on removal of working (and actually important) features. For example: So would has been "Improved" last time: - Address book became unusable. It is easier to remember address then to find an address in metamask contact book or to add it there. - It is simply impossible to customize Fee. Buttons just disabled. So you will pay as much as Metamask decided - option for customizing this gone. So looking forward for new updates. The latest version I think will contain only the "Metamaask" button and empty popup. You are on the right way. And from the other hand - I can't even approve spending a currency with Trezor - popup just closes itself instantly. One more bug, which Metamask team may fix for the years. So extension is definitely dead for me.

  • (2023-05-11) Pixel Patchwork: Great extension and perfect wallet for standard ERC20 tokens / chains. Also it has a good integration into development tools like remixIDE. I had to laugh when reading all the negative comments. Maybe people should try understand what they are doing before putting money in a technology they do not understand and where they are completely responsible for their own actions. Blaming MetaMask for high fees clearly shows that there is zero understanding of the topic. Its like blaming your car for high gas prices. If your coins got stolen it is certainly due to some virus on your machine or you connected the wallet to a scam site or someone has stolen your mnemonic or private key from your machine. I have been using it for several years with zero issues. MetaMask is certainly not the silver bullet but for basic use-cases it is fine.
