# Setup Polygon (Matic Mainnet) on MetaMask
## Install the Metamask Extension from the Store
Visit the [browser extension marketplace](https://chrome.google.com/webstore/detail/nkbihfbeogaeaoehlefnkodbefgpgknn) and download the MetaMask extension.
## Create a MetaMask Wallet or Import One
I’d suggest creating a new one if you haven’t done so.
Click import wallet if you have an existing wallet.
Setup your password and secret recovery phrase somewhere safe.
Setup MetaMask to connect to Matic Network.
Switch the connected blockchain by clicking on the tab saying Main Ethereum Network, we need to add the Matic network.
Scroll down until you find **Custom RPC.**
Enter in the Matic Mainnet settings as follows:
* **Network Name:** Matic Mainnet
* **New RPC URL:**
* **ChainID:** 137
* **Symbol:** MATIC
* **Block Explorer URL:**
Click **Save**.
You have now connected to the Matic mainnet with your Metamask Wallet.
