How to Add Base to MetaMask: step by step
1. Open MetaMask settings
In the MetaMask extension or app, click on the account icon and select ‘Settings’ from the dropdown menu.
2. Access the networks menu
In Settings, find and click on ‘Networks’ to manage the list of available networks in your MetaMask wallet.
3. Add a network manually
Click on the ‘Add a network’ button. If you do not see this option, you may need to use the ‘Add Network’ button under the ‘Networks’ section.
4. Enter network details
Input the following details for the Base network: Network Name: Base, New RPC URL: https://mainnet.base.org, Chain ID: 84531, Currency Symbol: ETH, Block Explorer URL: https://base.org.
5. Save the new network
After entering the details, click ‘Save’ to add the Base network to your MetaMask wallet.
6. Switch to the Base network
Once saved, you can switch to the Base network by clicking on the network dropdown menu at the top of your MetaMask wallet and selecting ‘Base’.
7. Test the network connection
Send a small amount of ETH to your wallet on the Base network to ensure everything is working correctly.
Fees and how long it takes
Typical fees for adding a network to MetaMask are zero, but you may incur gas fees for testing transactions on the Base network. The process should take only a few minutes, depending on your internet connection and the speed of the network.
Factors affecting timing include network congestion and the performance of your device.
Stay safe
- Double-check all network details from official sources to avoid connecting to the wrong network.
- Be aware that on-chain transfers are irreversible, so ensure you are using the correct address and network.
- Test with a small amount of ETH first to confirm the network is working as expected.
- Keep your MetaMask seed phrase secure and never share it with anyone.
- Beware of phishing attempts; only enter network details manually from trusted sources.
If something goes wrong
Network not appearing in the list — Ensure you have entered the network details correctly and clicked ‘Save’. Refresh the list if necessary.
Unable to connect to Base network — Check your internet connection and verify that the RPC URL is correct. Try switching to another network and back.
Transaction fails on Base network — Ensure you have sufficient ETH for gas fees and that you are using the correct network. Retry the transaction with a higher gas limit if needed.
