In simple terms, the Base blockchain is an Ethereum Layer 2 network built by Coinbase. It is designed to make onchain transactions faster and less expensive while keeping compatibility with Ethereum wallets, addresses, tokens and apps.
Therefore, this detailed beginner guide explains what Base is, how it works, which wallets support it and how to make a first transaction without mixing up networks.

What is Base?
In addition, Base is a separate blockchain network that settles important data back to Ethereum. Instead of asking Ethereum mainnet to process every user action directly, Base processes transactions on its Layer 2 and posts transaction data to Ethereum.
Therefore, this design gives users an Ethereum-like experience with lower fees and quicker confirmations. Base documentation currently describes transactions as settling in under a second and costing less than one cent, although actual fees can change with activity and the type of transaction.
How Base works in simple terms
In addition, think of Ethereum as the main record and Base as a faster checkout lane connected to it. Users sign normal EVM transactions. For example, a sequencer orders those transactions into Base blocks, while transaction data is posted to Ethereum so independent participants can reconstruct and verify the chain.
In addition, Base currently operates with one active sequencer. Its protocol also uses validators and fault-proof mechanisms that can challenge invalid state claims. That is why Base is described as a rollup built on Ethereum, not a completely independent Layer 1.
Is Base the same as Coinbase?
However, no. Coinbase is a centralized company and exchange. Base is an open blockchain network built by Coinbase. You can use Base through Coinbase products, but you can also use it with self-custody wallets and independent apps.
For instance, anyone should be able to deploy a compatible smart contract or send a transaction without opening a Coinbase exchange account.
Does Base have its own token?
In addition, Base uses ETH for network fees. For example, a token merely using the word “Base” in its name is not automatically an official network token. Beginners should be particularly careful with websites or social accounts promoting a supposed required Base gas token.
What can you do on Base?
- Send ETH, USDC and other supported tokens.
- Swap tokens through decentralized exchanges.
- Supply assets to lending markets or borrow against collateral.
- Trade NFTs and mint supported collections.
- Use social, gaming, payment and AI applications.
- Deploy EVM smart contracts and build apps.
However, every activity has its own risk. For example, a low network fee does not make an unknown token, NFT or smart contract safe.
Which wallets support Base?
In addition, Base is a standard EVM network. Therefore, most wallets that support custom Ethereum networks can use it. Common choices include MetaMask, Coinbase Wallet or Base Account, Rabby, Rainbow and hardware wallets used through a compatible interface.
Meanwhile, your usual EVM address normally remains the same when you switch between Ethereum, Base and other EVM networks. However, the balances do not. ETH held on Ethereum and ETH held on Base are recorded on different networks.

How to connect a wallet to Base
- Install a reputable EVM wallet from its official website or app-store listing.
- Create a new wallet or import one using the wallet’s official recovery process.
- Open the network menu and look for Base.
- If Base is not preloaded, add the official network details shown in the table above.
- Switch to Base and confirm that the wallet displays the correct network.
Meanwhile, never enter a recovery phrase into a network-addition form. An RPC setup requires public network information, not private wallet secrets.
How to get funds onto Base
However, the correct method depends on where your assets are now.
- From a supported exchange: choose Base as the withdrawal network when that option is available.
- From a Coinbase account: Base documentation recommends withdrawing supported ETH, USDC or cbBTC directly to Base.
- From Ethereum: use a supported bridge such as Superbridge or Brid.gg.
- From another chain: use a route explicitly supporting that source network and Base.
As a result, always verify the destination network, token and receiving address. Then send a small test amount before moving a larger balance.
How to make a first Base transaction
- Switch the wallet to Base.
- Check that you have the asset you want to send and enough ETH for gas.
- Paste the recipient’s EVM address.
- Compare the first and last characters with the intended address.
- Send a small test transaction.
- Open the transaction in BaseScan and wait for confirmation.
- Send the remaining amount only after the recipient sees the test.
Base safety checklist for beginners
- Bookmark official websites instead of following sponsored search results.
- Confirm the network before every deposit, withdrawal or bridge action.
- Verify token contract addresses through the issuer’s official source.
- Read wallet requests before signing. For example, a message signature and a token approval do different things.
- Use a separate wallet with limited funds for unfamiliar apps.
- Do not share a seed phrase, private key or one-time login code.
- Review and revoke approvals that are no longer needed.
Common Base problems and fixes
The token is missing after a transfer
For example, check the address on BaseScan first. If the transaction succeeded, the wallet may simply need the correct Base token contract added to its asset list.
The wallet shows the wrong balance
Before continuing, make sure the wallet is displaying Base, not Ethereum mainnet. However, the same address can show different balances on each network.
A transaction is failing
Additionally, confirm that you have enough ETH for gas, the app supports Base and the transaction is not using an expired quote. If necessary, disconnect and reconnect the wallet after checking the website address.
Frequently asked questions
Is Base an EVM network?
Still, yes. Base documentation calls it a standard EVM chain, so Ethereum tools, wallets and libraries can work with its network settings.
What coin pays gas on Base?
Consequently, ETH pays Base network fees.
Can I send Base assets to an Ethereum address?
However, the address format may be identical, but the receiving service must support the Base network. An exchange deposit page that supports only Ethereum mainnet may not credit a Base transfer.
Where can I check a Base transaction?
For instance, use BaseScan and search the transaction hash or public address.
