How to add a custom token to MetaMask? Where to find the contract address?

Accessing the MetaMask Interface

1. Open the MetaMask browser extension or mobile application and ensure you are logged into your wallet.

2. Navigate to the Assets tab where your current token balances are displayed.

3. Scroll down and locate the “Import Tokens” button—this may appear as a plus icon or text link depending on your interface version.

4. Click the button to open the token import modal, which presents three tabs: Custom Token, Token Lists, and Discover.

5. Select the Custom Token tab to proceed with manual entry of token parameters.

Locating the Correct Contract Address

1. Visit the official website of the token project—always verify authenticity through verified social media links or domain certificates.

2. Check the project’s documentation or “Tokenomics” section for Ethereum or EVM-compatible chain deployment details.

3. Navigate to blockchain explorers such as Etherscan for Ethereum, BscScan for BNB Chain, or Arbiscan for Arbitrum, and search using the token’s official name or ticker.

4. Confirm the contract address is marked as “Verified” and matches the one published by the team on their Telegram, Discord, or Twitter announcements.

5. Cross-reference the address with at least two independent sources before proceeding—unverified addresses may lead to irreversible loss of funds.

Entering Token Parameters Manually

1. Paste the verified contract address into the “Contract Address” field in the MetaMask import modal.

2. MetaMask will automatically fetch the token symbol and decimals if the contract is verified and follows ERC-20 standards.

3. If auto-detection fails, manually enter the token symbol exactly as defined in the contract—case sensitivity matters.

4. Input the correct number of decimals; common values are 18 for most tokens, but some use 6, 8, or 9—incorrect decimals distort balance display.

5. Click “Next”, then “Add Tokens” to confirm and integrate the asset into your wallet interface.

Verifying Token Appearance and Functionality

1. Return to the Assets tab and scroll until the newly added token appears in your list.

2. Check that the balance reflects accurately—if it shows zero despite holding tokens, confirm the network selection matches the token’s deployment chain.

3. Initiate a small test transaction to an external address or another wallet under your control to validate send functionality.

4. Monitor the transaction hash on the relevant blockchain explorer to confirm on-chain execution.

5. Observe whether token metadata—such as logo and description—loads correctly; missing visuals indicate incomplete token list integration but do not affect core functionality.

Frequently Asked Questions

Q: Why does MetaMask show “Unable to fetch token information” after adding a custom token?A: This occurs when the contract is unverified on the explorer or the RPC endpoint MetaMask uses does not support the token’s ABI call. The token remains functional for transfers even without metadata.

Q: Can I add a BEP-20 token to MetaMask while connected to the Ethereum network?A: No. You must switch MetaMask to the BNB Smart Chain network first. Attempting to add a BEP-20 token on Ethereum will result in incorrect balance detection or failure to load.

Q: Is it safe to paste a contract address from a random Telegram group?A: Absolutely not. Malicious actors frequently share counterfeit addresses mimicking legitimate tokens. Always obtain addresses only from official project domains or verified blockchain explorer pages.

Q: What happens if I enter the wrong number of decimals?A: Your displayed balance becomes mathematically inaccurate—either inflated by orders of magnitude or reduced to near-zero. The underlying tokens remain intact, but user interface misrepresentation increases risk of erroneous transactions.
