The Ethereum blockchain is a powerhouse in the decentralized world, but high transaction fees and slow processing times can hinder user experience. Enter Layer 2 (L2) scaling solutions—innovative protocols designed to enhance speed and reduce costs while maintaining Ethereum’s robust security. Among these, Base Network has emerged as a leading contender, backed by the trusted exchange Coinbase. If you're eager to explore decentralized applications (dApps), NFTs, or DeFi projects on this fast-growing L2, you’ll first need to add the Base Network to your MetaMask wallet.
This comprehensive guide walks you through every step—from manual configuration to mobile setup—and includes essential tips for security, token management, and ecosystem navigation. Whether you're a developer testing on testnets or a crypto enthusiast diving into new opportunities, this tutorial ensures a smooth onboarding process.
What Is Base Network?
Base Network is an Ethereum Layer 2 scaling solution developed by Coinbase using the open-source OP Stack, the same framework behind Optimism. It's designed to deliver faster transactions and lower gas fees while inheriting Ethereum’s security model. By operating as a rollup, Base batches transactions off-chain before submitting them to Ethereum, significantly improving efficiency.
Despite being a separate network, Base maintains full compatibility with existing Ethereum tools, including wallets like MetaMask, smart contracts, and dApps. This seamless integration makes it easy for developers and users alike to transition from Ethereum Mainnet to Base without learning new systems.
Key Base Network Details
To successfully connect your wallet, here are the official parameters:
- Network name: Base Network
- New RPC URL:
https://mainnet.base.org - Chain ID:
8453 - Currency symbol:
ETH
Note: The native currency on Base is still ETH, which is used to pay for gas fees. However, due to L2 optimization, these fees are typically much lower than on Ethereum Mainnet.
How to Add Base Network to MetaMask
There are multiple secure ways to integrate Base with MetaMask. Below are three reliable methods tailored for different user preferences.
Method 1: Manual Addition via MetaMask Extension
Adding Base manually gives you full control over the configuration process.
👉 Discover how easy it is to set up next-gen blockchain networks in minutes.
- Open your MetaMask extension in Chrome or any supported browser.
- Click the current network name (e.g., "Ethereum Mainnet") at the top-left.
- Select "Add Network" from the dropdown menu.
- Choose "Add a network manually".
Fill in the following details:
- Network Name:
Base Network - New RPC URL:
https://mainnet.base.org - Chain ID:
8453 - Currency Symbol:
ETH - Block Explorer URL (optional):
https://basescan.org
- Network Name:
- Click "Save".
- Once saved, click "Switch to Base Network" to begin using it immediately.
✅ Tip: Always verify the Chain ID and RPC URL to avoid phishing risks.
Method 2: Connect Through Base’s Official Website
For a more automated and secure experience, use Base’s official site.
- Visit base.org in your browser.
- Click "Connect Wallet" in the top-right corner.
- Select MetaMask from the list of available wallets.
- Confirm the connection request in your MetaMask popup.
- Approve the network addition when prompted.
- Choose "Switch Network" to start interacting with Base dApps.
This method reduces human error and ensures authenticity since you're connecting directly through the official domain.
Method 3: Use BaseScan Blockchain Explorer
BaseScan, built by Etherscan, is the go-to explorer for Base Network activity. You can also use it to quickly add the network.
- Go to basescan.org.
- Scroll down and click "Add Base to MetaMask".
- Confirm the action in your MetaMask wallet by clicking "Approve".
This shortcut is ideal for users already browsing blockchain data and wanting instant access.
How to Add Base Network on Mobile
MetaMask’s mobile app supports Base Network setup with nearly identical steps.
- Open the MetaMask app on your iOS or Android device.
- Tap the network selector at the top (e.g., "Ethereum").
- Tap "Add Network", then choose "Custom RPC".
Enter:
- Network Name:
Base Network - RPC URL:
https://mainnet.base.org - Chain ID:
8453 - Symbol:
ETH
- Network Name:
- Tap "Save", then confirm switching networks.
You’re now ready to explore Base-powered apps on the go.
Adding Base Testnets for Developers
Developers testing smart contracts or dApps should use one of Base’s testnet environments:
Option 1: Base Goerli Testnet
- Network Name: Base Goerli
- RPC URL:
https://goerli.base.org - Chain ID:
84531 - Block Explorer: goerli.basescan.org
Option 2: Base Sepolia Testnet
- Network Name: Base Sepolia
- RPC URL:
https://sepolia.base.org - Chain ID:
84532 - Block Explorer: sepolia-explorer.base.org
👉 Learn how developers are building the future of Web3 on scalable L2s like Base.
These testnets allow risk-free experimentation. You can obtain test ETH from faucets like the Base Discord or community portals.
How to Import Base Tokens into MetaMask
After switching networks, your wallet won’t automatically display Base-based tokens like $DEGEN or $BRICK unless imported.
Manual Import Steps:
- Ensure you’re on the Base Network in MetaMask.
- Scroll down and tap "Import Tokens".
- Paste the token’s contract address (found on CoinGecko or BaseScan).
- Confirm token details and click "Import Tokens".
Using CoinMarketCap:
- Search for a Base token on coinmarketcap.com.
- Copy its contract address.
- Click the MetaMask icon next to it (if available).
- Approve the import in your wallet.
This feature streamlines access to emerging meme coins and utility tokens within Base’s growing ecosystem.
