The Polygon network, formerly known as Matic, is one of the largest scaling solutions for Ethereum today. Popular for its rapid transactions and near-zero gas fees, a flood of users and protocols are now operating on the network.
Step-by-Step Polygon DeFi Guide
Note: This tutorial assumes you already use the MetaMask wallet for Ethereum. If you don’t already have MetaMask, you will need to download it for your browser or mobile device.
- Add Polygon Mainnet to Your MetaMask Wallet.
Polygon is a highly popular network, so it’s easy to add it to your MetaMask wallet with just a few clicks:
- Open the MetaMask extension and click the network dropdown arrow, in the top-left corner.
- Click “Add Network”.
- Find Polygon Mainnet in the “Popular custom networks” list and click “Add”.
- Click “Approve” to confirm the addition of the network.
- Use the Polygon Bridge
- Visit the official Polygon bridge at https://portal.polygon.technology/ and click “Connect Wallet”.
- Select MetaMask from the list of available options. Confirm the connection in the MetaMask popup window.
- Select “Bridge” in the sidebar on the left.
- Enter the amount ETH you wish to bridge to the Polygon network.
- Select “Polygon POS” from the dropdown menu in the “Transfer to” box.
Important: You’ll need MATIC on the Polygon chain to conduct any transactions.
- If you don’t already have MATIC in your Polygon account, toggle the switch next to “Low gas, Refuel now” to the “on” position.
- Enter the number of MATIC you want on the other side.
This will convert some of your ETH to MATIC during the bridging process.
- Click “Bridge ETH to Polygon POS” to start the bridging process and confirm the transaction in the MetaMask popup window.
There’s a waiting period for your funds to be accessible on the other side, so allow around 20 minutes for the bridging process to be completed.
3. Use a Polygon DApp
There’s an ever-growing number of DApps on Polygon, including several major protocols which originated on Ethereum.
To use a DApp on Polygon, simply:
- Switch to the Polygon network within your MetaMask wallet.
- Navigate to the DApp of your choice in your web browser.
- Connect to the DApp, the same way as you would on the Ethereum network.
