Create an ERC-20 Token on Base

What Is a Base Token?

A Base token is a standard ERC-20 token deployed on Base, an Ethereum Layer-2 network incubated by Coinbase and built on the OP Stack. Because Base is fully EVM-compatible, a token you create on it uses exactly the same ERC-20 interface as one on Ethereum — the functions transfer, balanceOf, approve and the rest — so every wallet, DEX and explorer that supports ERC-20 supports your Base token out of the box.

What makes Base distinctive is not the token standard but the environment around it. Base settles its transactions to Ethereum for security, yet keeps fees tiny, and it plugs directly into Coinbase's products and its large user base. That combination of low cost, Ethereum security and a built-in consumer audience is why Base has attracted a wave of memecoins, social tokens and consumer apps — the "onchain" ecosystem.

In short: your Base token is a real ERC-20, identical in mechanics to an Ethereum ERC-20, but it lives on a faster, far cheaper network with a distribution advantage through Coinbase.

How to Create a Token on Base, Step by Step

Creating a Base token here takes under a minute and never requires code. You keep full custody the entire time, and Base is already pre-selected in the form.

1. Confirm Base is selected. The network selector at the top of the form is already set to Base, and the fee shows 0.02 ETH. When you connect, your wallet switches to Base automatically — and if the network is not yet added to your wallet, it is added for you.
2. Configure your token. Enter a name (e.g. "My Base Token"), a symbol (2–8 characters, e.g. MBT), a total supply and the number of decimals (18 is standard). Toggle any optional features — mintable, burnable, taxable, anti-whale and more — all included in the flat fee.
3. Connect your wallet. Connect Coinbase Wallet, MetaMask, Rabby, Trust, OKX or any WalletConnect-compatible wallet. The address you connect becomes the owner of the ERC-20 token and receives 100% of the initial supply.
4. Review, confirm and deploy. Check the review card, approve the flat 0.02 ETH fee plus a few cents of Base gas in your wallet, and the contract is deployed, verified on BaseScan, and the full supply and ownership are transferred to you — instantly and irreversibly.

There is no account, no email and no login. You keep ETH on Base for gas — you can bridge it from Ethereum or move it directly from Coinbase.

Base and Other Supported Networks

The same audited contract compiles identically across every supported EVM chain, so your token behaves the same everywhere. What differs is gas cost, the flat fee (always charged in the network's own coin), and which ecosystem your token plugs into. Base stands out for near-zero gas plus Coinbase distribution.

Base you are here

An Ethereum Layer-2 incubated by Coinbase and built on the OP Stack. Base settles to Ethereum for security but keeps gas to a fraction of a cent, and benefits from tight Coinbase integration and a fast-growing consumer and memecoin ecosystem. Trade on Uniswap or Aerodrome. The gas coin is ETH.

ERC-20 on Base and Other Standards

Because Base is EVM-compatible, it uses Ethereum's token standards directly. Fungible tokens are ERC-20; NFTs are ERC-721; multi-token contracts are ERC-1155. There is no separate "Base standard" — a Base token is simply an ERC-20 that happens to be deployed on Base.

For a coin, memecoin, utility token or governance token on Base, ERC-20 is the right standard — which is exactly what this tool creates.

Token Features Explained

Every feature below can be toggled on at creation and is covered by the single flat 0.02 ETH fee. Because the contract is generated from audited building blocks, adding a feature never weakens the rest of the token. Keep it simple — a leaner contract is easier for holders to trust.

• Mintable — lets the owner create new tokens after launch, with an optional cap.
• Burnable — permanently destroys tokens to reduce supply.
• Deflationary — burns a small percentage on every transfer.
• Reflection — redistributes a fee from each transaction back to holders.
• Taxable — collects a configurable buy and sell tax for marketing, liquidity or a treasury.
• Anti-whale — caps the maximum wallet size as a percentage of supply.
• Liquidity pool — routes a share of supply straight into Uniswap on Base so trading can begin immediately.

Supply, Decimals and Tokenomics

Tokenomics is the design of your token's economy — how many exist, how they are divided, and how they enter circulation. Three fields on the form shape it directly.

Total supply is the number of tokens minted at launch. There is no single correct figure; Base memecoins often use one billion or more. Remember that supply and price are inversely related for the same market cap.

Decimals set how divisible each token is. The standard is 18, matching ETH. Leave it at 18 unless you have a specific reason, for maximum compatibility with Base wallets and DEXs.

Distribution decides who holds supply after launch. Reserving portions for a Uniswap/Aerodrome liquidity pool, the team and the community — ideally with visible vesting — is a strong credibility signal on Base, where communities scrutinize onchain holdings closely.

How Much Does It Cost to Create a Base Token?

The total cost is a single flat fee of 0.02 ETH, plus Base network gas — and because Base is a Layer-2, that gas is typically a fraction of a cent. There are no subscriptions, tiers or per-feature charges; every feature is included.

Network	Flat fee	Typical gas	Standard
Base	0.02 ETH	Fraction of a cent	ERC-20
Ethereum	0.02 ETH	Higher (mainnet)	ERC-20
Arbitrum	0.02 ETH	Very low	ERC-20
Optimism	0.02 ETH	Very low	ERC-20
Polygon	600 POL	Minimal	ERC-20
BNB Chain	0.1 BNB	Very low	BEP-20

Base's near-zero gas is one of its biggest draws — you get Ethereum security without Ethereum's fees. Just keep a little ETH on Base to cover gas.

Should You Launch on Base or Another Network?

Base is an excellent default for consumer-facing tokens, memecoins and anything that benefits from Coinbase's reach. But because each deployment is independent, you can pick whatever fits — the token is identical.

• Choose Base (this page) for near-zero gas, Ethereum security and Coinbase distribution.
• Choose Ethereum for the deepest liquidity and the strongest credibility — at higher gas.
• Choose Arbitrum for the largest L2 DeFi ecosystem and deep trading liquidity.
• Choose Optimism for the OP Stack chain Base itself is built on, with a governance-driven culture.
• Choose Polygon or BNB Chain for very low fees and large, independent audiences.

Many teams launch on more than one network. You can always start on Base and add Ethereum later once there is traction.

Security, Ownership and Trust

Every contract this tool deploys is built on OpenZeppelin's audited libraries, with no unaudited custom code. Because Base settles to Ethereum, your token inherits Ethereum-grade settlement security. After deployment, your source code is automatically verified on BaseScan, so anyone can read exactly what the contract does.

Ownership and the entire supply are transferred to your wallet the moment deployment completes; the platform keeps no admin keys or backdoors. You can renounce ownership after launch to prove the token can never be changed — a common trust signal in Base's onchain community. Keep the owner wallet secure.

After You Create Your Base Token: Listing on Uniswap

Deploying the contract is the beginning, not the end. A typical Base launch checklist:

1. Confirm and save the contract address. Open your token on BaseScan, confirm the verified source, and save the address — it is your token's permanent identity.
2. Add liquidity. Pair your token with ETH on Uniswap or Aerodrome, the main DEXs on Base, so people can trade it.
3. Add it to wallets. Import the contract address into Coinbase Wallet or MetaMask and share it with holders.
4. List and get discovered. Submit to CoinGecko, CoinMarketCap and DEX screeners like DexScreener. Base tokens often spread quickly through onchain social feeds.
5. Build your community. A clear website, honest communication and active channels matter more than any single feature.

Create a Token on Another Network

Base is selected on this page, but the same no-code creator works across six EVM networks. Launch the identical token on any of them:

Common Base Token Use Cases

The ERC-20 standard on Base powers many kinds of projects:

• Memecoins and community tokens — a huge category on Base's onchain social scene.
• Consumer app tokens — points, credits or rewards for apps built on Base.
• Utility tokens — access to a product, platform or service.
• Governance tokens — voting power in a DAO or protocol.
• Creator and social tokens — tokens tied to a creator, brand or community.

Common Mistakes to Avoid

• No ETH on Base for gas. Bridge or transfer a little ETH to Base before deploying.
• Losing the owner wallet. Whoever controls it controls the token. Back up your keys.
• Launching with no liquidity. A token with no Uniswap/Aerodrome pool cannot be traded. Plan liquidity first.
• Over-engineering the contract. Only enable features you actually need.
• Setting extreme taxes. High buy/sell taxes discourage trading and look suspicious on screeners.
