ERC-20 vs BEP-20: What's the Difference?

ERC-20 and BEP-20 are the two most common token standards you'll encounter, and they're often confused — partly because they're so similar. If you're deciding where to launch a token or just trying to understand the difference, this guide compares them clearly: what they share, where they differ, and how to choose.

The short answer

ERC-20 and BEP-20 are technically almost identical standards on different networks. ERC-20 is the token standard on Ethereum; BEP-20 is the equivalent on BNB Chain (formerly Binance Smart Chain). Both are EVM-compatible, so they share the same core functions and behave the same way for wallets and apps. The real differences come from the networks they run on, not the standards themselves.

What ERC-20 is

ERC-20 is the original fungible-token standard, defined on Ethereum. It established the common interface — transfer, approve, balanceOf and so on — that every wallet and DeFi protocol relies on. Because it came first and runs on Ethereum, ERC-20 is the most widely supported, most liquid, and most trusted token standard in crypto. See what is an ERC-20 token.

What BEP-20 is

BEP-20 is BNB Chain's token standard, designed to be compatible with ERC-20. It uses the same interface, so BEP-20 tokens work with EVM wallets like MetaMask and BNB Chain DEXs like PancakeSwap. BNB Chain was built for lower fees and higher throughput, which made BEP-20 popular for cost-sensitive activity and retail trading.

How they're the same

• Both are EVM standards with the same function set and events.
• Both use 0x addresses in the same format.
• Both work with MetaMask and EVM-compatible wallets.
• Both support the same kinds of features — mintable, burnable, taxable, and so on.
• Creating either is nearly the same no-code process.

How they differ

Fees and speed

The most noticeable practical difference is cost. BNB Chain generally has lower gas fees and faster confirmations than Ethereum mainnet, which is appealing for frequent, small transactions. Ethereum's fees are higher and fluctuate with demand — see Ethereum gas fees explained. If raw transaction cost is your top priority, BNB Chain wins; if trust and liquidity matter more, Ethereum does.

Security and decentralization

Ethereum is more decentralized, with a large, distributed validator set securing the network — a key reason it's considered the most credible base layer. BNB Chain achieves lower fees partly through a smaller validator set, which trades some decentralization for performance. For projects where maximum trust and censorship resistance matter, Ethereum's profile is a meaningful advantage.

Ecosystem and liquidity

Ethereum hosts the deepest liquidity, the most blue-chip DeFi protocols, and the widest institutional recognition. BNB Chain has a large, active ecosystem too, especially among retail users and lower-cost applications. Where your target users and the liquidity you need already are should heavily influence your choice.

Addresses look identical — be careful

Both chains use the same 0x address format, which causes a dangerous confusion: an address that exists on Ethereum also "exists" on BNB Chain, but they're different networks. Sending an ERC-20 token directly to a BEP-20 context (or vice versa) without a bridge can lose your funds. Always confirm you're transacting on the correct network. Moving assets between chains requires a bridge, which locks tokens on one side and mints a wrapped version on the other.

Can a token live on both?

Yes — many projects exist on multiple chains via bridges. Typically the token is deployed natively on one chain, and a bridge creates a wrapped, pegged version on the other. These are technically separate contracts kept in sync by the bridge. Multi-chain presence broadens reach but adds complexity and bridge risk, so it's usually a later-stage decision.

Which should you choose?

• Choose Ethereum (ERC-20) if you want maximum trust, the deepest liquidity, the strongest brand recognition, and access to blue-chip DeFi — and you're willing to pay higher gas.
• Choose BNB Chain (BEP-20) if low fees and fast, cheap transactions are your priority and your audience is already there.

Many serious projects favour Ethereum for its credibility, accepting higher costs as the price of being on the most established network. There's no universally right answer — it depends on your priorities.

Creating either

Because both are EVM standards, creating a token on either is a similar no-code process: connect a wallet, set name, symbol and supply, and deploy. To launch an ERC-20 on Ethereum specifically, use Create ERC-20 Token and follow our step-by-step guide.

Conclusion

ERC-20 and BEP-20 are the same idea on two networks: nearly identical standards, different chains. ERC-20 on Ethereum offers the deepest liquidity, the most trust and the strongest decentralization at higher fees; BEP-20 on BNB Chain offers lower fees and speed with a more retail ecosystem. Pick based on where your users and liquidity are and how much you value trust versus cost — and never confuse the matching address formats when moving funds between them.
