Configure BlockVision's RPC Node on Polygon

Follow this guide and we will show you how to use BlockVision’s ultra fast node to interact with Polygon mainnet and testnet.
  • The default node for Polygon set in your Web 3.0 wallet is too congested, causing slow transactions, extra high Gas fee, and connection issues?
  • Want to be informed by your socials (Discord, Telegram, or Slack) in real-time when a transaction is verified or dropped?
  • Want to be able to see all your event history?
  • Want to have a cooler node, because it's private and different from what everyone else is using?
Follow this guide and we will show you how to use BlockVision’s ultra fast node to interact with Polygon mainnet and testnet.
We will use MetaMask for demonstration purposes here.
