How to Add/Switch Networks on MetaMask

MetaMask can connect to any Ethereum-compatible network, featuring several default networks and the ability to connect to a custom network.

Add Matic/Polygon Network

Polygon, previously called the Matic Network, facilitates token transfers in a scalable, fast, and cheap manner. AnRKey X uses Polygon to deploy our smart contracts, using it to enable asset swapping from layer 1 to layer 2 of Ethereum, as well as lightning fast and affordable gameplay transactions.

To connect to Polygon, visit their website at https://wallet.polygon.technology. Then, sign in using one of the following wallets:

Once you have signed in, you will be able to see a popup with the two bridges connecting Matic to Ethereum, and what they can do. Once you close this popup, you will be able to see your token balance for both your Polygon Wallet and your Ethereum Wallet.

A popup will appear asking you to add the Matic/Polygon network automatically. If you do not receive a popup, or you accidentally dismiss the popup, you can continue onto the instructions below to manually add the Matic/Polygon Network:

Click on the network selection button on the top of the MetaMask app, then select “Custom RPC”.

Then, input the following information:

Network Name Polygon

New RPC URL https://polygon-rpc.com

Chain ID 137

Currency Symbol MATIC

Block Explorer URL https://polygonscan.com/

Click “Save”, and you will now be connected to the Matic/Polygon mainnet.

Switch to Ethereum Network

To switch to Ethereum Network, you'll see a dropdown menu at the top of your wallet.

Choose "Ethereum Mainnet" from the options provided

Once you select "Ethereum Mainnet", the switch to Ethereum Network is complete.

Switch to Matic/Polygon Network

To switch to Matic Network, you'll see a dropdown menu at the top of your wallet.

Choose "Matic Network" from the options provided. Some MetaMask accounts might label this network as "Polygon Network".

Once you select "Matic Network", the network switch is complete.
