Add networks to MetaMask

Using Ankr as the blockchain provider for MetaMask makes user interaction on Web3 not just easy and slick but also PRIVATE. We DON'T collect users' blockchain addresses — end of the story. Feel free to check our terms and privacy policy to be sure.

For MetaMask to interact with IoTeX through Ankr's infrastructure, add a required IoTeX network either via Web3 API platform's or MetaMask's UI.

Via Web3 API platform

To be added soon.

Via MetaMask

To add IoTeX Mainnet, follow these steps:

1. In MetaMask extension, click Networks (drop-down menu) > Add network to open Settings.

2. In the Add a network pane, click Add a network manually, then enter the network details and click Save:

   • Network name: IoTeX Mainnet by Ankr RPC.
   • New RPC URL: https://rpc.ankr.com/iotex/{your_token}.
   • Chain ID: 4689.
   • Currency symbol: IOTX.
   • Block explorer URL: https://iotexscan.io/.

Congrats — you've just added Ankr as the blockchain provider for MetaMask to interact with IoTeX Mainnet.
