MetaMask Made Easy: Use Chainlist to Add Any EVM Chain

Navigating the expansive world of blockchain technology requires a robust crypto wallet like MetaMask, which serves as our gateway to decentralized applications (dApps), smart contracts, and a multitude of EVM-compatible networks. With the proliferation of Ethereum Virtual Machine (EVM) chains such as Ethereum, Polygon, BNB Chain, and Arbitrum, integrating these networks into MetaMask can seem daunting. Chainlist transforms this process, offering a seamless solution to add any EVM chain with precision and ease. We deliver an exhaustive guide to using Chainlist to enhance MetaMask, providing step-by-step instructions, network details, and practical applications for DeFi traders, NFT collectors, and blockchain developers as of June 18, 2025. This resource empowers us to unlock the full potential of our Web3 experience.

Understanding Chainlist and EVM Chains

Chainlist operates as a comprehensive directory for EVM-compatible blockchain networks, providing verified data including Chain IDs, RPC URLs, currency symbols, and block explorer URLs. As of mid-2025, it supports over 385 networks, encompassing mainnets, Layer 2 solutions, and testnets. This platform eliminates the need for manual configuration, which often involves sifting through technical documentation and risking errors.

EVM chains refer to blockchain networks that support the Ethereum Virtual Machine, enabling compatibility with Ethereum-based smart contracts and dApps. Examples include Polygon (Chain ID: 137), BNB Chain (Chain ID: 56), and Optimism (Chain ID: 10). Chainlist integrates with MetaMask to simplify adding these networks, ensuring we connect to reliable endpoints and explore the Web3 ecosystem efficiently.

Prerequisites for Adding EVM Chains

Before utilizing Chainlist to add EVM chains to MetaMask, we ensure the following are in place:

  • MetaMask Installation: Install the MetaMask extension from https://metamask.io for browsers like Chrome, Firefox, Edge, or Brave, or download the MetaMask app from the iOS App Store or Google Play Store.
  • Wallet Configuration: Set up a MetaMask wallet with a secure seed phrase and password, storing the phrase offline to protect assets.
  • Stable Internet: A consistent connection facilitates smooth interaction with Chainlist and MetaMask.
  • Basic Technical Awareness: Familiarity with RPC endpoints, Chain IDs, and network parameters enhances the process.

With these essentials met, we proceed to integrate EVM chains using Chainlist.

Step-by-Step Guide to Add EVM Chains with Chainlist

We outline a detailed process to add any EVM chain to MetaMask via Chainlist, catering to both desktop and mobile users.

Step 1: Access the Chainlist Platform

Open a browser and navigate to the official Chainlist website at https://chainid.network. The interface features a searchable database of EVM networks, updated regularly to reflect new additions. Bookmark the site to avoid phishing attempts, which often mimic legitimate URLs. The Chainlist homepage includes a search bar and network filters for easy navigation.

Step 2: Connect MetaMask to Chainlist

Establish the connection with these steps:

  1. Click the “Connect Wallet” button in the top-right corner of the Chainlist homepage.
  2. Select MetaMask from the wallet options.
  3. Choose the desired account in the MetaMask prompt and click “Next”.
  4. Approve the connection by clicking “Connect”.
  5. Confirm the wallet address displays, indicating a successful link.

Switch accounts by revisiting MetaMask and reconnecting as needed.

Step 3: Select the EVM Chain

Locate the target EVM chain using Chainlist’s search functionality:

  1. Enter the network name (e.g., Polygon, Arbitrum, Goerli) or Chain ID (e.g., 137, 42161, 5) in the search bar.
  2. Browse the results or enable the “Include Testnets” toggle for development networks.
  3. Review the network details, including Chain ID, RPC URL, and currency symbol, against official sources.

For instance, selecting BNB Chain reveals its Chain ID (56), RPC URL (https://bsc-dataseed.binance.org/), and currency (BNB).

Step 4: Add the EVM Chain to MetaMask

Integrate the network with these instructions:

  1. Click the “Add Chain” or “Add to MetaMask” button next to the network.
  2. MetaMask displays a confirmation window with details such as:
  3. Verify the information and click “Approve”.
  4. Choose “Switch Network” to activate or “Close” to stay on the current network.

The EVM chain now appears in the MetaMask network list.

Step 5: Verify EVM Chain Functionality

Confirm the addition with these steps:

  1. Open MetaMask and select the new network from the network dropdown.
  2. Ensure it loads without errors.
  3. Visit the network’s block explorer (e.g., https://bscscan.com for BNB Chain) to verify the address and transactions.

Retry the process if the network fails to appear.

Mobile Users: Adding EVM Chains via MetaMask App

For MetaMask mobile app users:

  1. Launch the MetaMask app on an iOS or Android device.
  2. Tap the browser icon to access the in-app browser.
  3. Navigate to https://chainid.network.
  4. Follow the desktop steps: connect wallet, search network, and add via “Add Chain”.
  5. Approve and switch networks as prompted.

This ensures consistency across platforms.
