If you’re starting with crypto, DeFi, or NFTs, you’ve likely heard of Chainlist MetaMask TechEduByte, a widely used crypto wallet. But did you know that MetaMask alone only supports Ethereum by default? To access other blockchains like Polygon, BNB Chain, or Arbitrum, you need to configure them manually. That’s where Chainlist comes in. TechEduByte explains how this tool simplifies the process of adding networks to MetaMask safely and efficiently.
Understanding Chainlist and MetaMask
Chainlist is an online directory of verified blockchain networks compatible with the Ethereum Virtual Machine (EVM). Each network entry contains essential details:
- Network name
- Chain ID
- RPC URL
- Native currency symbol
- Explorer link
MetaMask is a secure wallet that lets users store crypto, interact with dApps, and manage multiple assets. Without tools like Chainlist, adding new networks involves manually entering RPC URLs and other details — a process that can easily go wrong. Chainlist automates this by pushing the correct information directly to MetaMask with just a click.
Why Use Chainlist With MetaMask?
Adding networks manually can be confusing, especially for beginners. A small mistake in the RPC URL or Chain ID can prevent transactions from working or even create security risks. Chainlist solves this by providing verified network configurations, making it faster, safer, and more reliable.
In short, Chainlist acts as a bridge between your MetaMask wallet and the growing ecosystem of EVM-compatible blockchains.
