Add Base to MetaMask

  1. Visit Chainlist
  2. Search "Base", and confirm network details (Chain ID: 8453)
  3. Click Add to MetaMask and approve the request to add network. 

Key Takeaways

  • Base is a Layer 2 rollup network built to scale the Ethereum network, built on the OP Stack. It is backed by the largest listed cryptocurrency exchange – Coinbase.

  • The Base mainnet launched on August 9, 2023, and has seen significant usage since this time. A notable contributor to Base's popularity is the launch of friend.tech, a decentralized social media application on the network.

  • In this guide, we take you through the process of downloading and installing a MetaMask wallet, integrating the Base network, and adding native tokens on the network to your MetaMask wallet.


Add Base to MetaMask

 

Add the Base Network Manually

  1. From your MetaMask wallet dashboard, click the network dropdown from the top left corner of your wallet. Click Add network.

Add Base network manually

  1. A list of pre-set networks is shown, however it doesn't include Base; click on Add a network manually to add Base.

  1. On the form, enter the network details accordingly

  • Network name: Base

  • Network URL: https://developer-access-mainnet.base.org

  • Chain ID: 8453 

  • Currency symbol: ETH 

  • Block explorer URL: https://basescan.org

Enter Base RPC details​​​​

  1. Click Save to complete.

Base is now available in your MetaMask wallet. You can switch to Base by clicking the network icon from the top left corner of your screen and selecting Base from available networks. You can also install other EVM networks through this procedure, although you’ll need to look for their network details to add them manually. 

Another way to install the Base network is via ChainList.

Add Base to MetaMask Through Chainlist

On Chainlist, you can add available EVM networks with a few clicks. Chainlist collates EVM network details and allows users to add new networks to their wallets without needing to go through the manual process of sourcing and entering network details. To add Base to MetaMask with Chainlist:

  1. Visit Chainlist

  2. Enter Base in the search bar at the top of the page. As seen in the above network details, 8453 is the Base network’s Chain ID. Click Connect Wallet on the search results with the correct Chain ID.

  3. Follow the prompts in your wallet to add the network to your wallet.

After approving the permission to add Base, you have successfully added Base to MetaMask and you can now switch to the Base network.

Add Base to MetaMask With Blockchain Explorers

You can also add Base to MetaMask through blockchain explorers, like Blockscount’s Base Mainnet Explorer and BaseScan

  1. At the bottom of the page, click the Add Base to MetaMask button with a MetaMask icon.

  1. You’ve successfully added Base to MetaMask.

Now, let's proceed to add a native Base network token to your MetaMask wallet.

Adding Custom Base Network Tokens to the MetaMask Wallet

For this guide, we will use GeckoTerminal to obtain the contract address of an actively traded token on the Base network. The Base network also has a handy explorer with a token page that lists the smart contract tokens minted on the platform. Before adding any new tokens, always verify that the smart contract addresses are correct.

  1. On your wallet, switch to the Base network.

  2. Visit the GeckoTerminal page for Base network pools.

  3. Click on the desired pool, scroll to the contract area, and copy the assets contract.

You can search for the asset you wish to copy its contract. For this guide, we will use USDbC, one of the most actively traded assets on the network. USDbc is bridged USDC on the Base network. This token contract can also be obtained from CoinGecko.

Token contract address from GeckoTerminal

  1. Return to your wallet, and click Import tokens to add the asset to your wallet.

Import Base tokens into Metamask

  1. Enter the token’s smart contract address in the provided input box. The asset’s remaining details will populate automatically.

  2. Click Add custom token to proceed.

Add custom token to Metamask

  1. Click Import tokens to complete.

Complete by importing tokens

USDbC is now available in your wallet. You can now see your balances without using the network’s explorer, and click on the asset to send or receive. You can add more network tokens to your wallet through this procedure.

Final Thoughts

With over 100 million users on Coinbase, Base has the potential to bring non-DeFi natives on chain, and many protocols are looking to Base to grow their user base. By connecting to Base, you’ll be able to explore the variety of protocols available on the network.
