Create an ERC-20 token

ERC-20 is the standard that built the modern token economy. The vast majority of tokens you’ve heard of are ERC-20 tokens, and the standard’s universal support across exchanges, wallets and DeFi protocols makes it the gold standard for serious projects. The good news is that creating an ERC-20 token no longer requires writing code — you can deploy one in minutes with a no-code creator. This guide explains exactly how.

What is an ERC-20 token?

ERC-20 is the technical standard for fungible tokens on Ethereum and other EVM-compatible blockchains. “Fungible” simply means every unit is identical and interchangeable, like ordinary currency. The standard defines a shared set of rules — how balances are tracked, how transfers work, how supply is reported — so that any wallet, exchange or application built for ERC-20 can support every ERC-20 token automatically.

That universality is the whole point. Because ERC-20 is so widely adopted, a token following the standard works everywhere in the Ethereum ecosystem the moment it’s deployed. It’s this network effect that makes ERC-20 the most important and most supported token standard in all of crypto.

Why create an ERC-20 token?

There are compelling reasons to choose ERC-20:

• The widest support. ERC-20 tokens are accepted by more exchanges, wallets and DeFi protocols than any other standard.
• The deepest liquidity. Ethereum has the most liquidity in crypto, which matters for serious trading.
• Credibility. Launching on Ethereum carries weight with many audiences and investors.
• A vast ecosystem. Endless tools, integrations and infrastructure already exist.
• Layer-2 flexibility. You can deploy ERC-20 tokens cheaply on Base and Arbitrum while keeping full compatibility.

If reach, credibility and liquidity are your priorities, ERC-20 is the natural choice. When you’re ready, you can create your token at /token-generator/ethereum/.

ERC-20 on Ethereum vs layer-2s

One important nuance: ERC-20 isn’t limited to Ethereum mainnet. Because Base and Arbitrum are EVM-compatible layer-2s, tokens you create on them are effectively ERC-20 tokens too — with the same standard and compatibility, but at a fraction of mainnet gas costs. This gives you a choice. Deploy on Ethereum mainnet when you want maximum reach and credibility and can absorb higher fees. Deploy on a layer-2 like Base or Arbitrum when you want ERC-20 compatibility at low cost. For many projects, a layer-2 is the smart way to get most of Ethereum’s advantages without its expense — see our guide to the best blockchain to create a token for a full comparison.

What you need to create an ERC-20 token

The requirements are simple:

• A crypto wallet that supports Ethereum — MetaMask is standard. If you don’t have one, see how to create a crypto wallet.
• A small amount of ETH for gas (on mainnet or your chosen layer-2).
• Your token details — name, symbol, total supply and decimals.
• A no-code ERC-20 token creator, and a few minutes.

No development environment and no coding required.

How to create an ERC-20 token step by step

Here’s the full process:

1. Set up MetaMask and select Ethereum (or a layer-2 like Base or Arbitrum).
2. Fund your wallet with ETH for gas.
3. Open an ERC-20 token creator such as /token-generator/ethereum/ and connect your wallet.
4. Enter your token details — name, symbol, total supply, decimals.
5. Choose any optional features like mintable or burnable, only if needed.
6. Review carefully, since these values are permanent.
7. Deploy by confirming the transaction and paying the gas fee.
8. Verify and add liquidity so people can trade your token.

Within minutes, your ERC-20 token exists on-chain with a permanent contract address.

Configuring your ERC-20 token

The details you enter define your token forever. Choose a clear, memorable name that isn’t already used by a known project, and a distinctive symbol of three to five characters. Set your total supply to fit your concept, and decimals to 18, which is the ERC-20 standard. Optional features such as mintable, burnable or a transaction tax are available, but restraint is wise — a clean, standard token is easier for exchanges to support and for buyers to trust. Over-engineering an ERC-20 contract adds complexity and scrutiny without usually adding value.

How much does it cost to create an ERC-20 token?

This is where your choice of network matters most. On Ethereum mainnet, gas fees can be significant and fluctuate with congestion, making mainnet the most expensive place to deploy a token. On layer-2s like Base and Arbitrum, the same ERC-20 deployment costs only a small fraction. So if cost is a concern but you want ERC-20 compatibility, a layer-2 is the answer. A no-code creator may add a small service fee, still far below a developer’s price. For a complete breakdown, see our guide on the cost to create a cryptocurrency.

ERC-20 token development without coding

“ERC-20 development” once meant writing Solidity, testing it, and auditing it — skilled, expensive, error-prone work. No-code creators have changed that completely. They use audited, standard ERC-20 contract templates and insert your details, deploying from your wallet in one transaction. The result is a genuine ERC-20 token, identical in quality to one a developer would write, without the cost or the risk of a hand-written bug. For most projects that simply need a standard token, this is the smarter path; custom development only makes sense for genuinely unusual logic.

After deployment: liquidity and listing

Once your ERC-20 token is live, it can’t be traded until you add liquidity. You pair a portion of your token with ETH in a liquidity pool on a decentralized exchange (such as Uniswap), which sets the price and opens trading. Provide enough liquidity for smooth trading, and consider locking it to reassure holders. Then verify your contract on Etherscan (or the relevant layer-2 explorer) so it’s transparent, and pursue listings on trackers like CoinGecko and CoinMarketCap as you grow. Each step widens your reach and builds credibility.

Security when creating an ERC-20 token

The same safety rules apply as anywhere in crypto, and they matter. Never share your seed phrase or private key — no legitimate creator asks for it. Verify the creator’s URL before connecting your wallet, since fake sites are the most common attack. Review every MetaMask transaction before approving it. And use a reputable, audited creator rather than an unknown tool. Following these keeps the process safe, and good security also signals to your community that your project is trustworthy.

Common mistakes to avoid

• Deploying on mainnet without budgeting for gas, then being surprised by the cost.
• Skipping liquidity, so the token can’t be traded.
• Not locking liquidity, which worries cautious buyers.
• Hoarding supply in one wallet and destroying trust.
• Stopping at deployment, with no community plan.

A brief history of the ERC-20 standard

ERC-20 stands for “Ethereum Request for Comments 20,” a proposal introduced in 2015 that defined a common interface for fungible tokens on Ethereum. Before it, tokens worked in inconsistent ways, and every wallet or exchange had to handle each one differently. ERC-20 fixed that by establishing a shared set of functions every compliant token would implement, so that infrastructure built for one token would work for all of them. This simple agreement unleashed an explosion of token creation and became the foundation of the entire token economy. Understanding this history explains why ERC-20 is so dominant: its value isn’t any single feature, but the universal compatibility that comes from everyone following the same standard.

ERC-20 vs BEP-20 vs SPL

It helps to see how ERC-20 relates to the other major standards. ERC-20 is the original, used on Ethereum and its layer-2s, with the widest support and deepest liquidity but higher mainnet fees. BEP-20 is BNB Chain’s near-identical equivalent — so similar that the two are often described together — offering the same familiar behaviour at much lower cost. SPL is Solana’s native standard, built on a different architecture for extremely fast, cheap transactions. For a creator, the practical takeaway is that ERC-20 and BEP-20 feel almost the same to work with and differ mainly in cost and audience, while SPL belongs to Solana’s ecosystem. Choosing among them is really choosing a blockchain — which is why our guide to the best blockchain to create a token is the natural companion to this decision.

How ERC-20 tokens work under the hood

An ERC-20 token is a smart contract that implements the standard’s required functions — tracking balances, handling transfers, reporting total supply, and allowing approvals so other contracts can move tokens on a holder’s behalf. When you deploy, this contract is published to the blockchain and assigned a permanent address. From then on, every wallet and exchange that understands ERC-20 can interact with your token through those standard functions. A no-code creator handles all of this by taking an audited template, inserting your parameters, and deploying it from your wallet. You get a fully standard ERC-20 token without writing or reviewing any of the underlying code — the standardisation is exactly what makes safe automation possible.

When to use Ethereum mainnet vs a layer-2

Since your ERC-20 token can live on mainnet or a layer-2, it’s worth being deliberate. Choose Ethereum mainnet when maximum credibility, the deepest liquidity, and the broadest exchange support justify higher gas costs — often the case for larger or more serious projects. Choose a layer-2 like Base or Arbitrum when you want genuine ERC-20 compatibility at a small fraction of the cost, which suits most newer projects and anyone mindful of fees. A practical strategy some teams use is to launch affordably on a layer-2 to build traction, then consider mainnet presence later if the project grows to need it. The key is that you’re not forced into expensive mainnet fees just to get an ERC-20 token — the layer-2 route gives you the standard’s benefits affordably.

Growing your ERC-20 token

As with any token, creation is the easy part and growth is the real work. After launching your ERC-20 token, focus on building liquidity so trading is smooth, locking it to earn trust, and verifying your contract on the explorer for transparency. Then invest in community and marketing: clear messaging, active channels, and consistent presence. Pursue listings on trackers and, as you grow, exchanges. Ethereum’s ecosystem offers enormous reach, but reach only matters if people discover and believe in your project. The tokens that thrive are run by creators who keep building long after deployment, treating the launch as the beginning of a sustained effort rather than the finish line.

Is ERC-20 right for your project?

ERC-20 is an excellent choice when reach, credibility and liquidity matter most — for serious utility tokens, projects aiming at broad exchange listings, or anything that benefits from Ethereum’s deep ecosystem. It’s less ideal as your only consideration if cost is the dominant concern and you don’t specifically need Ethereum’s reach, in which case a low-fee chain like BNB Chain or Solana might serve you better. The encouraging nuance is that you can have much of ERC-20’s value affordably by deploying on a layer-2 like Base or Arbitrum, which keeps the standard and compatibility while cutting fees dramatically. So the real question isn’t just “ERC-20 or not,” but “ERC-20 on mainnet or on a layer-2” — and for most newer projects, a layer-2 ERC-20 is the sensible answer. Match the choice to your priorities, and remember that any well-run token on a sensible network will outperform a neglected one on a “perfect” one.

Common ERC-20 mistakes and how to avoid them

A few avoidable errors trip up new creators. The first is deploying on Ethereum mainnet without budgeting for gas, then being shocked by the cost — check current fees first, or use a layer-2. The second is launching with insufficient liquidity, leaving the token barely tradeable; provide enough that trading is smooth. The third is failing to lock liquidity, which makes cautious buyers suspect a rug pull. The fourth is over-engineering the contract with unnecessary features that add complexity and deter buyers; a clean standard token is usually stronger. The fifth, and most common across all tokens, is stopping at deployment with no plan to build a community. Avoiding these is mostly discipline: budget properly, keep the token simple, provide and lock liquidity, and treat the launch as the start of real work. Do that and your ERC-20 token starts from a position of trust and tradeability.

Conclusion

Creating an ERC-20 token gives you the most widely supported, credible token standard in crypto. With MetaMask, some ETH for gas, and a no-code creator, you can deploy one in minutes — on Ethereum mainnet for maximum reach, or on a layer-2 like Base or Arbitrum for the same compatibility at a fraction of the cost. As always, the deployment is the easy part; liquidity, community and marketing are what give your token lasting value.
