How to Add New Networks and Token Types to MetaMask Wallet

MetaMask serves as a versatile and widely-used cryptocurrency wallet, essential for many crypto investors. It supports numerous blockchains and continuously evolving token types for storage and transfers. However, beginners often encounter two primary challenges:

1. Adding a new network (e.g., Polygon, Fantom)
2. Adding a new token type (e.g., IDO tokens, BNB, MATIC)

This guide provides step-by-step solutions, along with practical tips to streamline your MetaMask experience for effective crypto asset management.

Adding a New Network

To ensure security and avoid scams, always verify network details via the official blockchain documentation before proceeding.

Step 1: Navigate to "Add Network"

Open MetaMask → Click the network dropdown → Select "Add Network."

Step 2: Enter Network Details

Prepare the following information:

• Network Name (e.g., Fantom Opera)
• RPC URL (e.g., https://rpc.ftm.tools/)
• Chain ID (e.g., 250 for Fantom)
• Currency Symbol (e.g., FTM)
• Block Explorer URL (e.g., https://ftmscan.com/)

👉 Explore Fantom’s official RPC endpoints

Step 3: Verify via Official Sources

Example for Fantom:

1. Visit Fantom’s documentation.
2. Locate the Mainnet RPC URL and Chain ID.

Step 4: Submit and Save

Paste the verified details into MetaMask → Click "Save."

Adding a New Token

Avoid scavenging Discord groups for token addresses—always check project documentation first.

Step 1: Select "Import Tokens"

In MetaMask, navigate to "Assets" → Click "Import Tokens."

Step 2: Locate the Token Contract Address

Example for Tomb Finance:

1. Visit Tomb’s docs.
2. Find the Token Contract Address (e.g., 0x6c021Ae822BEa943b2E66552bDe1D2696a53fbB7 for TOMB).

Step 3: Paste and Auto-Fill Details

Enter the contract address → MetaMask auto-populates Token Symbol and Decimals → Click "Add Custom Token."

Pro Tip:

For tokens not automatically detected, manually verify decimals (usually 18) via block explorers.

FAQ

1. Why isn’t my token balance showing after adding?

• Ensure you’re on the correct network.
• Verify the contract address. Tokens with identical names but different addresses (e.g., scam clones) are common.

2. Can I add multiple networks?

Yes! MetaMask supports Ethereum, BSC, Polygon, Fantom, etc. Repeat the "Add Network" process for each chain.

3. Is it safe to use public RPC URLs?

Stick to official endpoints. Malicious RPCs can compromise transactions.

• Token: Click the token → Scroll down → Select "Hide."
• Network: Settings → Networks → Click the trash icon.

Key Takeaways

• Always cross-check network/token details from official sources.
• Prioritize security over convenience—avoid unverified contract addresses.
• Use block explorers (e.g., Etherscan, FTMScan) for real-time transaction tracking.
