How to set up MetaMask for Cyber mainnet? (Social Graph)

MetaMask Installation and Initial Configuration

1. Launch Firefox browser and navigate to the Add-ons Manager. Search for MetaMask in the extension store and click “Add to Firefox” to install it.

2. Once installed, click the fox icon in the top-right corner of the browser to open the MetaMask interface.

3. Select “Get Started”, then choose “Create a Wallet”. Accept the terms and set a strong password for local access control.

4. Write down the 12-word secret recovery phrase on physical paper—do not store it digitally or share it with anyone.

5. Confirm the phrase by selecting each word in correct order. Upon completion, the wallet is initialized with a default Ethereum mainnet account.

Adding Cyber Mainnet Network Manually

1. In MetaMask, click the network selector dropdown located at the top-center of the interface.

2. Choose “Add Network” and then “Add a network manually” from the options menu.

3. Enter the following parameters: Network Name as Cyber Mainnet, New RPC URL as https://rpc.cyber.co, Chain ID as 320, Currency Symbol as CYBER, and Block Explorer URL as https://explorer.cyber.co.

4. Click “Save”. The network will appear in the list and become selectable immediately.

5. After saving, verify that the active network displays “Cyber Mainnet” and that the balance field reflects zero CYBER unless previously funded.

Connecting to Cyber Social Graph Applications

1. Visit cyber.co and click the “Connect Wallet” button in the upper-right corner.

2. Select MetaMask from the wallet options. A connection request will appear in the MetaMask popup window.

3. Approve the connection without signing any transaction—this only grants read access to your public address and network context.

4. Once connected, the site will load your CyberAccount identity if already registered, or prompt you to initialize one using ERC-4337 account abstraction.

5. If initializing for the first time, confirm the deployment transaction for your smart contract wallet on Cyber Mainnet. Gas fees will be paid in CYBER tokens.

Managing CYBER Token and Gas Payments

1. To fund your wallet with CYBER for gas, use a decentralized exchange such as Uniswap or SushiSwap configured for Cyber Mainnet.

2. Import the official CYBER token contract address: 0x0c8b4e96d142d152f6e5a592d442869777009564 into MetaMask via “Import Token” > “Custom Token”.

3. Ensure the token symbol displays as CYBER and decimals as 18 before confirming import.

4. When executing actions like profile creation or social link minting, MetaMask will auto-detect required CYBER for gas and display the exact amount prior to confirmation.

5. Transactions submitted to Cyber Mainnet are final within seconds and appear on explorer.cyber.co under your address’s transaction history.

Frequently Asked Questions

Q: Can I use my existing Ethereum private key to access Cyber Mainnet?A: Yes—importing a standard Ethereum key pair into MetaMask allows full access to Cyber Mainnet, provided the network is added manually and CYBER tokens are held for gas.

Q: Why does MetaMask show “Unknown Network” after adding Cyber Mainnet?A: This occurs when the Chain ID field was entered incorrectly. Double-check that Chain ID is exactly 320 and no extra spaces exist in any field.

Q: Is it safe to connect MetaMask to cyber.co for social graph operations?A: Yes—the site only requests permission to read your address and network state. No signature or approval is needed to view public profile data or follow relationships.

Q: What happens if I lose my MetaMask password but have the 12-word phrase?A: You can restore full access by reinstalling MetaMask, selecting “Import Wallet”, and entering the phrase. Your Cyber Mainnet assets and identity remain recoverable.
