Base Network Information You Need to Know

As an Ethereum scaling solution, Base offers a fast, low-cost EVM-compatible network. Understanding the key details of the Base network positions developers to effectively leverage its benefits. This guide covers everything you need to know about Base's chain specifics, wallet connectivity, bridging assets, and more.

Overview of Base

First, let's briefly introduce Base. Base is an Ethereum Layer 2 rollup developed collaboratively by Coinbase and Optimism. As an L2, it inherits Ethereum's security while scaling throughput and reducing fees.

Base provides full EVM equivalence, meaning existing Ethereum tools and apps work with no modifications. It aims to make Ethereum accessible for mainstream users and developers.

Now let's dive into the Base network details.

Base Mainnet and Testnet Parameters

Like other EVM networks, Base uses certain identifiers and settings that wallets and software need to connect. Here are the key details:

Base Mainnet

  • Network Name: Base Mainnet
  • RPC Endpoint:
  • Chain ID: 8453
  • Symbol: ETH
  • Block Explorer:

Base Testnet (Goerli)

  • Network Name: Base Goerli
  • RPC Endpoint:
  • Chain ID: 84531
  • Symbol: ETH
  • Block Explorer:

These network details allow adding Base as a custom network in MetaMask, Coinbase Wallet, and other EVM-compatible wallets.

Connecting Your Wallet to Base

Once you know Base's parameters, connecting your wallet is straightforward.

For Coinbase Wallet, Base Mainnet and Testnet are built-in networks accessible from the default network selector.

For MetaMask, you need to add a custom network. Enter the RPC URL, chain ID, symbol, and block explorer for the network you want to use.

Once connected, you can start using dApps, transacting, and bridging assets to Base. Speaking of assets...

Bridging Assets from Ethereum

While Base is great for low-fee transactions, you'll need to bridge assets from Ethereum first.

bridging uses the Portal bridge at You'll need to:

  1. Connect your Base wallet
  2. Select the token and amount
  3. Approve the bridge contract
  4. Confirm the transactions on Ethereum and Base

After the bridge finalizes, your tokens will show in your Base wallet. Now you're ready to use DeFi, trade NFTs, and more!

Understanding Base Accounts

Base uses an Ethereum concept called Account Abstraction to improve key management.

Instead of one account address like Ethereum, Base gives each wallet two address types:

  • User Addresses - For transacting, holding assets
  • Contract Addresses - For deploying and managing smart contracts

This separation means you don't have to expose your main private key to deploy contracts.

When sharing your Base address, be sure to correctly copy your User Address - it will start with "0x". Contract Addresses look different.

Low Fees Enable New Use Cases

Base reduces Ethereum's high fees to expand the possibilities of Web3 apps. With fees of $0.10 or less, applications like:

  • Micropayments
  • NFT mints and trades
  • Complex smart contracts
  • On-chain gaming
  • Decentralized social networks

Become viable on Base when pricing out users on Ethereum. Expect an explosion of creativity and innovation thanks to low transaction costs.

Sequencing and Consensus on Base

Under the hood, Base achieves scalability using Optimistic Rollups. Batches of transactions are compressed and submitted to Ethereum in a rollup block.

The OP Stack manages transaction sequencing and consensus for rollup chains like Base. The OP Stack is open source software maintained by Optimism and Base developers.

Using a shared stack improves interoperability between chains compared to custom-built L2s. It's a foundational piece of Base's network architecture.

Future Decentralization Plans

While Base currently has centralized operation by Coinbase, the roadmap includes progressive decentralization. Specifically:

  • Decentralizing transaction sequencing to permissionless validators
  • Transitioning governance to a DAO model with BASE token holders
  • Making infrastructure and core contracts open source

This balances the need for an immediately usable L2 today with the Web3 goal of permissionless, community-run networks.


Understanding the technical foundations of Base puts developers in a position to capitalize on its speed and scalability. Key details like network parameters, account models, and the OP Stack underpin building dApps, DeFi products, NFTs, and more on Base.

As the network decentralizes further, Base aims to become an open ecosystem where anyone can build to reach millions of users - the next billion to crypto. With low fees and EVM compatibility, Base unlocks new possibilities and use cases for Web3.
