Configure BlockVision's RPC Node on Arbitrum
Follow this guide and we will show you how to use BlockVision’s ultra fast node to interact with Arbitrum Mainnet and Testnet.
  • The default node for Arbitrum set in your Web 3.0 wallet can be too congested, cause slow transactions, extra high Gas fees and even connection issues.
  • Want to be informed directly to your Discord, Telegram or Slack instantly when a transaction you sent is verified or dropped?
  • Want to be able to see all your event history?
  • Want to use an ultra fast-node, with high-availability and lightning fast response times?
Follow this guide and we will show you how to use BlockVision’s ultra fast node to interact with Arbitrum Mainnet and Testnet.
We will use MetaMask for demonstration purposes here.
