Blockchain is often seen as complex and overwhelming, especially for beginners. But don’t worry—you’re not alone! Many people, when first diving into the world of Web3, NFTs, and DeFi, feel the same way. Fortunately, there are tools designed to make things much simpler. One of those tools is Chainlist, and when paired with MetaMask, it becomes a game-changer for anyone using decentralized applications (dApps).
In this detailed guide by Techedubyte, we’ll explain everything you need to know about Chainlist MetaMask Techedubyte, using plain English and real-life examples. Whether you’re a curious newbie or a seasoned crypto user looking to expand to new chains, this article is tailored for you.
What Is Chainlist?
Before diving into the technical side, let’s begin with a quick story.
A friend of mine, Alex, was exploring a new NFT project on the Arbitrum network. He opened his MetaMask wallet and realized—wait a second—the Arbitrum network wasn’t even available! Confused and frustrated, he spent 20 minutes Googling RPC URLs, Chain IDs, and other details, trying to connect his wallet manually. Eventually, he gave up.
This is where Chainlist comes in.
Chainlist is a community-driven platform that lists Ethereum-compatible networks (EVM chains). With just a few clicks, users can add any EVM-compatible chain directly to MetaMask, without manually copying RPC URLs, Chain IDs, or currency symbols. In short, Chainlist simplifies connecting MetaMask to other blockchains like:
- Binance Smart Chain (BSC)
- Polygon (Matic)
- Avalanche
- Fantom
- Arbitrum
- Optimism
- And many more…
It’s maintained by the community and powered by data from Chain ID (chainid.network), making it one of the most reliable resources available.
What Is MetaMask?
If you’re here, you’re likely familiar with MetaMask, but let’s quickly review.
MetaMask is a non-custodial crypto wallet that allows users to interact with the Ethereum blockchain and other EVM-compatible chains directly through their browser or mobile device. It acts as a gateway to:
- Storing crypto assets
- Using decentralized apps (dApps)
- Signing smart contract transactions
- Swapping tokens
- Participating in DeFi and NFT ecosystems
But there’s a catch—MetaMask only includes the Ethereum Mainnet by default.
To interact with other chains, you need to manually add them, which is where many users get stuck. That’s why Chainlist + MetaMask is the perfect combo.
Why Use Chainlist with MetaMask?
Using Chainlist with MetaMask offers several benefits:
1. Saves Time
No more searching for RPC details or Chain IDs. A couple of clicks and you’re done.
2. Avoids Errors
Manual entry is prone to typos. One wrong number and your wallet might not function properly. Chainlist ensures accuracy.
3. Safe & Reliable
Chainlist is open-source and uses verified data. It’s a safer alternative to random Reddit threads or Twitter posts.
4. Supports Multiple Networks
From testnets like Goerli to Layer-2 chains like Optimism, Chainlist supports them all.
How to Use Chainlist with MetaMask (Step-by-Step Guide)
Let’s now walk you through the exact process of how to use Chainlist with MetaMask in a simple, step-by-step guide.
Step 1: Install MetaMask
If you haven’t already, here’s how to get MetaMask:
- Go to https://metamask.io
- Click Download
- Choose your browser or mobile device
- Install the extension or app
- Set up your wallet (create a new one or import using your seed phrase)
Important: Never share your seed phrase with anyone.
Step 2: Visit Chainlist
Now, head over to https://chainlist.org
You’ll be greeted with a clean interface and a search bar.
Step 3: Connect Your MetaMask Wallet
- Click the “Connect Wallet” button at the top right
- Approve the connection in MetaMask
- That’s it—you’re connected!
Note: This does not give Chainlist access to your funds. It only allows reading your wallet address to suggest compatible chains.
Step 4: Search for a Chain
Let’s say you want to add Polygon (Matic):
- Type “Polygon” in the search bar
- You’ll see a list of results—mainnet and testnet
- Click “Add to MetaMask” next to the chain you want
Step 5: Approve Network in MetaMask
MetaMask will show a popup asking for permission to add the network:
- Network Name: Polygon Mainnet
- RPC URL: https://polygon-rpc.com/
- Chain ID: 137
- Currency Symbol: MATIC
Click Approve, then Switch Network if you want to start using it right away.
That’s it—you’re now connected to Polygon via Chainlist!
Pro Tip from Techedubyte
Bookmark Chainlist.org and check regularly for updates or new chains. New Layer 2s and testnets are constantly being added.
Real-World Use Cases of Chainlist + MetaMask
Let’s break it down with a few examples of how people actually use this combo.
1. Gaming on Immutable X
Alice wanted to play a blockchain-based trading card game that uses the Immutable X network. She found it on Chainlist, clicked “Add to MetaMask,” and was up and running in under a minute.
2. DeFi on Arbitrum
John was exploring DeFi protocols on Arbitrum. Instead of manually adding the chain, he used Chainlist to safely connect and avoided a sketchy RPC URL from Twitter.
3. Minting NFTs on Optimism
Sophia discovered an NFT project only available on Optimism. Without Chainlist, she would’ve had to copy multiple parameters. Instead, she clicked once, approved, and got minting!
Is Chainlist Safe to Use?
Absolutely! However, here are a few safety tips to follow:
- Use the official website: Only use https://chainlist.org
- Double-check RPC URLs: Even though Chainlist is community-powered, always verify if you’re unsure.
- Don’t sign unknown transactions: Adding a network is safe, but signing transactions from unknown dApps is risky.
What Are RPC URLs, Chain IDs, and Gas Tokens?
Let’s quickly demystify these terms.
- RPC URL: The Remote Procedure Call endpoint connects your wallet to the blockchain node.
- Chain ID: A unique number that identifies the blockchain (e.g., Ethereum is 1, Polygon is 137)
- Currency Symbol: The default token used to pay for gas (e.g., ETH, MATIC)
Chainlist auto-fills all of these when adding a network to MetaMask. That’s why it’s so useful!
