ERC-20 vs BEP-20: what's the difference?

If you’re creating a token, you’ll quickly run into two standards: ERC-20 and BEP-20. They sound different, and they run on different blockchains, but they’re actually close cousins — so close that understanding one means understanding both. The choice between them is really a choice between two networks, and it affects your token’s cost, speed and reach. This guide explains the difference between ERC-20 and BEP-20 clearly, and helps you pick the right one.

ERC-20 vs BEP-20 at a glance

Factor	ERC-20	BEP-20
Blockchain	Ethereum (and L2s)	BNB Chain
Fees	Higher (mainnet)	Very low
Speed	Moderate	Fast
Reach	Widest support	Large, growing
Wallet	MetaMask	MetaMask
Compatibility	The original standard	ERC-20 compatible

The two are technically almost identical. The real differences come from the networks they run on.

What is ERC-20?

ERC-20 is the token standard for fungible tokens on Ethereum, introduced in 2015. It defines a shared set of rules — how balances are tracked, how transfers work, how supply is reported — so that any wallet, exchange or app built for ERC-20 supports every ERC-20 token automatically. Because Ethereum is the most established smart-contract blockchain, ERC-20 enjoys the widest support and deepest liquidity of any standard in crypto. It’s the gold standard for reach and credibility. To create one, see our guide on how to create an ERC-20 token.

What is BEP-20?

BEP-20 is the token standard on BNB Chain, and it was deliberately designed to be compatible with ERC-20. In practice, this means BEP-20 tokens share the same core functions and behave the same way as ERC-20 tokens — but they run on BNB Chain instead of Ethereum, with much lower fees. BEP-20 has become hugely popular for new tokens, presales and meme coins precisely because it offers the familiarity of ERC-20 at a fraction of the cost. To create one, see our guide on how to create a token on BSC.

The key differences

Since the standards themselves are nearly identical, the meaningful differences come from their networks:

• Fees. This is the biggest one. BEP-20 on BNB Chain is much cheaper than ERC-20 on Ethereum mainnet, where gas can be significant. For cost-conscious projects, BEP-20 is very attractive.
• Speed. BNB Chain generally confirms transactions faster than Ethereum mainnet.
• Reach and liquidity. ERC-20 has the widest exchange, wallet and DeFi support and the deepest liquidity, which matters for serious projects aiming at broad listings.
• Ecosystem and audience. Ethereum carries the most credibility and the largest DeFi ecosystem; BNB Chain has an enormous, active community especially receptive to new tokens.
• Network. ERC-20 lives on Ethereum (and EVM layer-2s), BEP-20 on BNB Chain.

Notice that none of these are about the standard’s code — they’re about choosing Ethereum or BNB Chain.

Are they compatible?

This is a common point of confusion. ERC-20 and BEP-20 follow the same standard and even use the same wallet (MetaMask), but they run on different blockchains, so a token on one isn’t automatically usable on the other. To move a token between Ethereum and BNB Chain, you use a bridge, which locks the token on one chain and issues a representation on the other. The standards’ similarity makes this kind of cross-chain tooling smoother, but day to day, an ERC-20 token and a BEP-20 token live in their own networks with their own liquidity. If you want presence on both, you deploy a version on each.

Which should you choose?

The decision comes down to your priorities. Choose ERC-20 if maximum reach, the deepest liquidity, and the strongest credibility matter most, and you can absorb higher fees — it’s ideal for serious projects aiming at broad exchange support. A great middle path is to deploy ERC-20 on a layer-2 like Base or Arbitrum, which keeps the standard and compatibility at much lower cost. Choose BEP-20 if low fees and a large, active community are your priorities — it’s perfect for beginners, presales and meme coins that want ERC-20 familiarity without Ethereum’s gas costs. Many first-time creators start with BEP-20 for its affordability. For a broader view that includes Solana and the layer-2s, see our guide to the best blockchain to create a token.

A brief history of both standards

Understanding where each standard came from explains why they’re so similar. ERC-20 was proposed on Ethereum in 2015 as a common interface for fungible tokens. Before it, tokens worked inconsistently and every wallet had to handle each one differently; ERC-20 fixed that by establishing shared rules, and it became the foundation of the entire token economy. BEP-20 came later, when BNB Chain launched as an EVM-compatible network. Rather than invent something incompatible, its designers based BEP-20 directly on ERC-20, so developers and users could bring their Ethereum knowledge and tooling straight over. In other words, BEP-20 exists because ERC-20 worked so well — it’s a deliberate, compatible adaptation for a cheaper, faster network. That shared heritage is exactly why the two feel almost identical to work with.

Technical similarities in detail

Because BEP-20 was modelled on ERC-20, the two share the same core functions — the standard ways to check balances, transfer tokens, approve other contracts to move tokens, and report total supply. A developer who understands one understands the other, and tools built for ERC-20 often work with BEP-20 with little or no change. Both use the same wallet (MetaMask), the same address format, and the same general concepts of decimals and supply. This deep similarity is a real practical benefit: skills, tools and habits transfer directly between the two. It also means that when you create a token, the experience of making a BEP-20 token versus an ERC-20 token is nearly the same — you fill in the same kind of details in a no-code creator. The differences you actually feel come from the network, not the standard.

Fees compared in practice

Fees are the single biggest practical difference, so it’s worth being concrete. On Ethereum mainnet, deploying an ERC-20 token and trading it can cost meaningfully more, and those costs rise when the network is busy — for some projects this is a genuine barrier. On BNB Chain, a BEP-20 deployment is usually just a few dollars, and ongoing trading fees are very low. For a project expecting lots of small transactions, or for a creator on a tight budget, that gap matters. The important nuance, covered below, is that ERC-20 doesn’t have to mean expensive — deploying on an Ethereum layer-2 brings ERC-20 costs down close to BNB Chain levels while keeping the standard.

ERC-20 on layer-2s: the cheap middle ground

Here’s a point many comparisons miss: ERC-20 isn’t limited to expensive Ethereum mainnet. Layer-2 networks like Base and Arbitrum are EVM-compatible, so tokens on them are effectively ERC-20 tokens — with the same standard and compatibility — but at a small fraction of mainnet fees. This changes the calculation considerably. If you love ERC-20’s reach and compatibility but worry about cost, a layer-2 ERC-20 gives you most of Ethereum’s advantages affordably, narrowing the price gap with BEP-20. So the real choice often isn’t simply “ERC-20 or BEP-20,” but “ERC-20 on a layer-2, or BEP-20 on BNB Chain” — two low-cost, compatible options. Our guide to the best blockchain to create a token compares these paths in full.

How bridging works between them

Since ERC-20 and BEP-20 live on different blockchains, a token on one isn’t directly usable on the other — but bridges connect them. A bridge locks your token on its home chain and issues a matching representation on the destination chain, letting value move between Ethereum and BNB Chain. Projects that want a presence in both ecosystems use bridges or deploy a separate version on each network. For most creators, though, the sensible approach is to launch on one standard and network first, build liquidity and community there, and only consider bridging or multi-chain expansion later if demand clearly justifies the added complexity.

Which do exchanges and users prefer?

Both standards are widely supported, but they have different strongholds. ERC-20 enjoys the broadest support across major exchanges, wallets and DeFi protocols, and Ethereum’s ecosystem carries the most credibility and deepest liquidity — which is why projects aiming at the widest reach often favour it. BEP-20 is supported across a large and active ecosystem too, with a huge community especially receptive to new and meme tokens, and its low fees make it very popular for accessible launches. Neither is “preferred” universally; it depends on the audience. Serious projects chasing maximum listings lean ERC-20, while cost-conscious and community-driven launches often lean BEP-20. Both give you a token that works seamlessly within its ecosystem.

Common mistakes when choosing a standard

A few avoidable errors trip up new creators at this decision. The first is assuming ERC-20 must mean expensive — it doesn’t, because layer-2s like Base and Arbitrum give you ERC-20 affordably. The second is choosing purely on fees without considering where your audience and liquidity are; the cheapest option isn’t always the best fit. The third is thinking the standards are interchangeable on-chain — they follow the same rules but live on different networks, so you need a bridge or a separate deployment to be on both. The fourth is overthinking the decision and stalling; both standards produce excellent tokens, so the choice matters less than actually launching and building. Decide based on your real priorities — cost, reach and audience — then move forward.

Quick decision guide

To make it simple: choose BEP-20 on BNB Chain if your priorities are low fees, a large active community, and an accessible launch — ideal for beginners, presales and meme coins. Choose ERC-20 if you want the widest reach, deepest liquidity and strongest credibility — and deploy it on Ethereum mainnet when you need maximum reach and can absorb the fees, or on a layer-2 like Base or Arbitrum when you want ERC-20 compatibility at low cost. For most first-time creators, BEP-20 or a layer-2 ERC-20 offers the best balance of affordability and capability. Whichever you pick, you get a standard, fully compatible token.

Common questions about ERC-20 and BEP-20

A few quick answers to frequent questions. Do ERC-20 and BEP-20 use the same wallet? Yes — MetaMask works for both; you just switch networks. Can I convert an ERC-20 token to BEP-20? Not directly; you’d use a bridge or deploy a separate version on the other chain. Is one more secure than the other? Both are secure for token creation; your own security habits matter more than the standard. Which is better for a meme coin? BEP-20 is popular and cheap for meme coins, though Solana’s SPL is also a strong meme option — see our BSC vs Solana comparison. Which should a beginner pick? BEP-20 for its low cost and easy entry, or a layer-2 ERC-20 for cheap Ethereum compatibility.

Conclusion

ERC-20 vs BEP-20 isn’t really a battle of standards — they’re nearly identical by design. It’s a choice between Ethereum’s reach and BNB Chain’s low cost. Pick ERC-20 (on mainnet or a cheaper layer-2) when reach and credibility lead your priorities, and BEP-20 when low fees and a big, receptive community matter most. Either way, you get a standard, fully compatible token.
