How to change RPC setting
In case of transaction delays or slow loading of data, it may be because of high network congestion on the Polygon network. Since some RPC endpoints may be busier than others at a particular time, changing the RPC endpoint URL might help.
In this guide, we will show you how to change RPC endpoint in Metamask's Matic network configuration.
Public RPC endpoints
Open your MetaMask wallet and click on My Accounts (circular button on the top right) as shown in the screenshot below.
Click on Settings.
Go to Networks and select Matic Mainnet (or Polygon, the name can differ).
Replace the old RPC endpoint with a new RPC endpoint provided at top of this guide and click save.
Congratulations, you have successfully changed your RPC endpoint.
*It's not guaranteed that changing RPC endpoint will result is less delays.
