## Getting Started

### Step 1: Add Network to Wallet

export const AddNetworkSection = () => (
  <>
    
      
        Remove any old 0G testnet configurations before adding Galileo (steps below).
      
    

    
      
      
    
  </>
);

<summary>Removing an old 0G testnet from MetaMask</summary>

The old testnet versions are no longer active. Remove them from your MetaMask network list before adding the current **0G Galileo Testnet**, to avoid conflicts.

1. Open MetaMask and click the network dropdown menu at the top.
