Whether you’re swapping tokens, adding liquidity, or just exploring the W Chain ecosystem, the first step is to connect your MetaMask wallet. This simple guide will walk you through everything you need to do — even if you’re a complete beginner.
What is MetaMask?
MetaMask is a popular crypto wallet and gateway to blockchain apps. It’s available as a browser extension and mobile app, and it lets you connect to Ethereum-compatible (EVM) blockchains — like W Chain.
What is W Chain?
W Chain is a next-gen Layer 1 blockchain focused on scalability, decentralization, and DeFi performance. If you’re planning to use dApps like W-Swap, you’ll need to first add W Chain to MetaMask.
How to Connect W Chain to MetaMask?
Step 1: Install MetaMask
If you don’t have MetaMask yet:
- Go to https://metamask.io
- Download and install the browser extension (Chrome, Firefox, Edge, or Brave) or mobile app.
- Create a wallet or import an existing one using your seed phrase.
Always back up your seed phrase securely and never share it with anyone!
Step 2: Open MetaMask and Add Network
- Open the MetaMask extension.
- Click the network dropdown (at the top, usually it will say “Ethereum Mainnet”).
- Click “Add a custom network”
Step 3: Enter W Chain Network Details
Use the following W Chain configuration (replace placeholders with actual details):
