MetaMask is one of the most popular crypto wallets for interacting with blockchains. By adding Parallax as a custom network, you can use MetaMask to create addresses, manage balances, and transfer Parallax coins (laxes). This guide will show you how to connect MetaMask to your local Parallax node.

​
Prerequisites

  • You have already installed and started the Parallax client.
  • MetaMask is installed in your browser (Chrome, Firefox, Brave, or Edge).

​
Step-by-step Guide

1

Open MetaMask settings

  1. Click the MetaMask extension in your browser.
  2. Open the account menu (top-right circle).
  3. Select Settings → Networks.
2

Add a custom network

Click Add a network and then choose Add a network manually.
3

Enter Parallax network details

Fill in the fields with the following information:
  • Network Name: Parallax Local
  • New RPC URL: http://127.0.0.1:8545
  • Chain ID: 2110 for mainnet, 2111 for testnet
  • Currency Symbol: LAX
  • Block Explorer URL: (optional) https://explorer.parallaxchain.org
The http://127.0.0.1:8545 RPC is provided by your local Parallax client. Make sure your node is running with the --http flag enabled.
4

Save and switch network

After saving, MetaMask will add Parallax Local to your list of networks.Select it, and MetaMask will connect to your local Parallax node.

​
Using MetaMask with Parallax

Once connected, you can:
  • Create new addresses: MetaMask will generate them automatically.
  • View balances: See how much laxes each address holds.
  • Send transactions: Transfer laxes to other addresses on the Parallax network.

​
Troubleshooting

  • If MetaMask can’t connect, ensure your node is running with HTTP enabled: 
    ./prlx --http --http.api "eth,net,web3"
  • Make sure the RPC URL (127.0.0.1:8545) is correct.
  • If using a firewall, check that port 8545 is not blocked.
  • If on Linux, make sure to set --http.addr 0.0.0.0 when starting the Parallax client: 
    ./prlx --http --http.addr 0.0.0.0 --http.api "eth,net,web"
  • Some browsers might fail to connect MetaMask to your local Parallax node. This can be fixed by running the client with: 
    ./prlx --http --http.vhosts "*" --http.corsdomain "*"
✨ That’s it! You’re now using MetaMask with Parallax to manage addresses and send Laxes.
