Use Metamask with OpenChain

Connecting MetaMask to OpenChain

  1. Let’s change that. We want to access the Settings to point the wallet towards OpenChain nodes.

2. On the Settings page, we want to locate the Networks menu.

We want to click Add Network in the top-right corner to manually add the OpenChain one – it doesn’t come packaged with MetaMask. It’s important to note that there are two networks we can use here: the testnet or the mainnet. Below are the parameters to fill in for each.

Mainnet (This is the one you are probably looking for)

  • Network name: OpenChain Network

  • RPC URL: https://mainnet.openchain.info

  • ChainID: 777

  • Symbol: OPC

  • Block Explorer: https://openchain.info

Testnet

  • Network name: OpenChain Test

  • RPC URL: https://opc-seed.openchain.info

  • ChainID: 776

  • Symbol: OPC

  • Block Explorer: https://testnet.openchain.info
