Configure EVM Chains on MetaMask
Learn how to configure EVM chains, like Binance Smart Chain, on MetaMask extension for seamless decentralized finance and blockchain applications.
Keystone with firmware versions M-5.0 provides full support for any EVM-compatible blockchains. Users can now add any EVM-compatible blockchains on Metamask and use Keystone with it.
This guide will show you how to add the Polygon (Matic Network) Network on Metamask as an example. The same method would apply for other chains. Let’s take a look in more detail.
For more information on how to use MetaMask with EVM-compatible blockchains, please visit the MetaMask official website.
2. Install MetaMask extension with version V10.8.0 or newer.
Users can choose to add Polygon (Matic Network) to MetaMask either automatically or manually.
1) Find the Polygon network on https://chainlist.org, choose the network (e.g. Polygon Mainnet) and click on [Connect Wallet].
2) Select the Account (e.g. Keystone 1), then click on [Next] > [Connect].
3) Click on [Add To MetaMask] > [Approve] > [Switch network].
4) Polygon Mainnet has now been successfully added to your MetaMask.
You can add custom networks to MetaMask manually but there's probably no reason to do so unless you're a software developer. If you would still like to do so manually, please follow the instructions below:
1) Run the MetaMask Extension and enter the MetaMask main page.
2) Click on the Network Selection button at the top of the MetaMask Extension > [Add Network].
3) Input the relevant Polygon details below into the blanks provided: Network Name: Polygon Mainnet. Then click [Save].
- Chain ID: 137
- Currency Symbol (optional): MATIC
Sometimes changing the RPC URL can help during network congestion:
4) You have now connected to the Polygon Mainnet with your Metamask Wallet!
