What is a Remote Procedure Call (RPC)?

RPC stands for Remote Procedure Call, and it is used to allow communication over a network.

In crypto, RPC details are often used when adding custom networks, as they tell the wallet how to connect to a specific blockchain.

Exodus doesn't support adding custom networks using RPC details. However, it's possible to add a custom network with MetaMask using the network's RPC details.

RPC Details can often be found in the network's official development documents.

  1. Go to MetaMask's website and download the MetaMask wallet.

  2. After installing and securing your 12-word secret key, click on Enabled networks.

    Please be very careful with your 12-word secret key and private keys, because they control access to your funds. Never share them with anyone, and only import them into platforms that you trust 100%. If you choose to import your private keys into a third-party platform, you do so at your own risk.

  3. a) Click on the Custom tab and b) select Add custom network.

  4. Enter the RPC details of the custom network (we'll use the Sonic network as an example):

    ​a) Network Name: Sonic Mainnet
    ​b) RPC: https://rpc.soniclabs.com
    ​c) Chain ID: 146
    ​d) Symbol: S
    ​e) Block Explorer: https://sonicscan.org
    ​f) To continue, click Save.

  5. When you have added it, you can switch to that network by a) clicking on the Custom tab, and b) selecting it.

  6. Once you have selected a custom network, you will see its name in your MetaMask wallet.
