To use Matic-Mainnet with Superfluid, you need to set a custom RPC URL on Metamask.
If you never added Polygon (ex Matic) to your Metamask, simply click here and click on "Matic" to add the RPC automatically.
If you already have an RPC endpoint for Matic, please follow these steps:
Step 1 - Open your Metamask Wallet and click on the Network menu on the Top Right
Step 2 - Select Custom RPC at the bottom of the menu
Step 3 - Insert the data below in the relative fields as asked by Metamask
New RPC URL
⚠ Warning, only Metamasks extensions on Firefox and Chrome are supported
Block Explorer URL
If you already have a network setup for Polygon using Chain ID 137 Metamask might refuse to add a new one, if this is the case you can edit your existing network configuration for Polygon following these steps:
Click My Accounts > Settings > Networks;
Update the RPC URL to one of those listed above.
Step 4 - Connect your wallet to Superfluid dashboard by visiting this link
Congratulations, you are all set to use Superfluid on Polygon 🎉
