Chainlist MetaMask Techedubyte – How Chainlist Works

Overview

When you use MetaMask or any other Web3 wallet, you sometimes need to connect to a blockchain network that is not already listed in the wallet’s default networks. This could be because you want to use a different blockchain for lower fees, or you are testing a smart contract on a development network.

Manually adding a blockchain to your wallet means you must find and type in specific details such as the Chain ID, RPC URL, network name, token symbol, and block explorer link. Typing these details incorrectly can cause failed transactions or even lead you to connect to an unsafe network.

Chainlist is a public and open tool that solves this problem. It keeps a verified list of networks that are compatible with Ethereum’s technology (EVM-compatible networks) and lets you add them to MetaMask and other wallets with just one click. This makes the process faster, easier, and safer.

Instead of searching across forums or random websites for the right information, you can simply go to Chainlist, search for the network, connect your wallet, and approve the addition.

How Chainlist Works

Chainlist is not a wallet itself. It is a website that acts like a library of blockchain network settings. It gives you the correct technical details and sends them to your wallet when you approve.

When you open the Chainlist site, you search for the network you need, such as Polygon or BNB Smart Chain. It shows you the main network and any test networks. You can connect your MetaMask wallet to the site so it can send the network information directly to MetaMask. Once you see the correct network name, you can select the option to add it to your wallet. MetaMask will open a small window showing the details, and you simply approve the addition.

This one-click process replaces the need to go through your wallet’s settings menu and manually type the network name, RPC URL, Chain ID, currency symbol, and block explorer URL.

Advantages of This Method

• No manual typing of technical data
• Much faster than traditional methods
• Lower chance of connecting to a wrong or fake network
• Supports both popular and lesser-known networks
