Adding BlockX to Metamask

The MetaMask browser extension or mobile web allows us to access Ethereum-compatible applications. It can be used to connect to BlockX through the official testnet or through a BlockX node.

Metamask also allows importing of different blockchains, making it a great solution for BlockX and similar ecosystems.

Below is an intuitive guide for adding the BlockX chain to Metamask:

  1. Open your MetaMask web extension (browsers - chrome, brave, forefox, opera) or mobile web (iOS/Android), then click on the circle in the upper right corner to open settings.

2. Click Settings at the bottom of the dropdown menu

3. Select Networks

4. Enter the following details below:

BlockX Mainnet

Network Name: BlockX


Chain ID: 190

Symbol: BCX


NOTE: Since the Chain ID of BlockX and another chain is same (100) , Metamask throws a warning . The Chain is determine by combination of Chain ID and RPC url so similar Chain ID should not be an issue. We are trying to resolve that with Metamask. The RPC URL is different so there will be no issue. Ignore the warning Metamask pops

BlockX Testnet (Atlantis)

Network Name: Atlantis


Chain ID: 19077

Symbol: BCX


5. Hit Save

From here, you will have the same wallet as your Ethereum or other EVMs. No need for a separate app for you to access your funds.

To add BlockX, select BlockX then click on the Green Button to add BlockX to Metamask

Make sure that the Chain ID and the Network URL is the same as above. It might also show a logo different than that of BCX later on but as long as you're connecting with the right RPC or Network URL and correct Chain ID of 100 you're in the right network. We'll work in adding the proper logo later on.
