MetaMask Legacy Web3

MetaMask Legacy Web3

Adds MetaMask's legacy window.web3 API to your browser

What is MetaMask Legacy Web3?
MetaMask Legacy Web3 is an add-on for Edge browsers that enables users to interact with the blockchain through outdated websites. It restores the original window.web3 API, which has been deprecated since December 2020 for enhanced security and performance. With this extension, you can access and use older, unmaintained websites that require the legacy API in tandem with the MetaMask wallet.

Chrome-Stats extension

The MetaMask extension provides an API to websites you visit so they can interact with the blockchain. In the past, we used to provide a complementary API known as window.web3. As of December 2020, we stopped injecting window.web3, which improves security and performance, but can break older and unmaintained websites. Using this extension in combination with the MetaMask wallet enables you to use those older sites as before.
