Add Custom Chains

Use Fordefi's Custom Chain feature to add an EVM-compatible chain to your MPC wallet using a custom RPC endpoint.

Incoming transactions are not automatically detected

On custom EVM-compatible chains:

  • Incoming transactions are not automatically detected and balances might require manual updating. See Refresh asset balance.
  • Tokens are not automatically detected unless they are added manually. See Add a watched asset.

Here's how you set up a custom chain:

  1. In the side menu, click Settings, then click Chains.

    alt

  2. Click Add EVM chain.

  3. In the dialog that is displayed, provide details in the relevant fields:

  • Chain ID: The ID of the chain.
  • Chain name: Assign a name. This can be arbitrary.
  • RPC URL: The URL of the blockchain node to connect to. The RPC server address. Search Chainlist for the chain that you want to add. Select an RPC node URL with a green-colored status. Currently, only RPC nodes with the prefix http:// or https:// are supported.
  • Currency symbol: The ticker symbol.
  • Type: Choose Mainnet or Testnet.
  • Block explorer link: The block explorer for the chain.
  1. Click Add.

The new chain is displayed in the list of custom chains.
