When diving into the world of cryptocurrencies, understanding token standards is essential. Two of the most widely used standards—ERC-20 and BEP-20—form the backbone of countless digital assets. While they may seem similar at first glance, key differences in their ecosystems, transaction costs, speed, and compatibility can significantly impact your crypto experience.
This guide breaks down everything you need to know about ERC-20 vs. BEP-20, helping you make smarter decisions whether you're trading, investing, or building on blockchain platforms.
What Are ERC-20 and BEP-20 Tokens?
Token standards are sets of rules that define how tokens behave on a blockchain. These rules govern everything from how tokens are transferred, how balances are tracked, and how they interact with wallets, decentralized applications (dApps), and smart contracts.
They ensure interoperability across platforms, making it easier for developers to build and users to manage digital assets.
ERC-20 Token Standard
ERC-20 is the most established token standard, built on the Ethereum blockchain. Introduced in 2015, it became the blueprint for fungible tokens—those that are interchangeable, like traditional currency.
The ERC-20 standard specifies functions such as:
- Transferring tokens between addresses
- Querying account balances
- Approving token spending by third parties

Because of its widespread adoption, ERC-20 tokens are supported by nearly every major wallet, exchange, and DeFi protocol. Examples include USDT (Tether), UNI (Uniswap), and LINK (Chainlink).
The ERC-20 standard was the first widely adopted framework for creating and managing tokens on Ethereum.
BEP-20 Token Standard
BEP-20 is the native token standard of the Binance Smart Chain (BSC)—now known as BNB Chain. Designed to be compatible with Ethereum’s ecosystem while offering faster transactions and lower fees, BEP-20 has become a popular alternative for developers and users alike.
Like ERC-20, BEP-20 supports fungible tokens and includes similar functionalities. However, it operates within BNB Chain’s consensus mechanism (Proof of Staked Authority), which allows for higher throughput and reduced costs.
Popular BEP-20 tokens include BNB (Binance Coin), CAKE (PancakeSwap), and BUSD (Binance USD).
Key Differences Between ERC-20 and BEP-20
Understanding the distinctions between these two standards helps you choose the right network based on your needs—whether it's cost-efficiency, speed, or ecosystem support.
Blockchain Ecosystem and Cross-Chain Compatibility
ERC-20 tokens exist solely on the Ethereum network. While they can be moved to other blockchains via bridges, they remain native to Ethereum. This gives them strong integration with thousands of dApps, wallets like MetaMask, and DeFi protocols such as Aave and Compound.
In contrast, BEP-20 tokens run on BNB Chain, a blockchain developed by Binance. One of its core advantages is Ethereum compatibility—meaning developers familiar with Ethereum tools can easily deploy projects on BNB Chain.
Moreover, cross-chain transfers between Ethereum and BNB Chain are possible using the Binance Bridge, allowing users to convert ERC-20 tokens into BEP-20 (and vice versa). This interoperability enhances flexibility but requires awareness of network selection during transactions.
Always ensure you're sending tokens to a wallet address that supports the correct standard—sending an ERC-20 token to a BEP-20-only wallet could result in loss of funds.
Transaction Fees and Speed
One of the biggest pain points with ERC-20 tokens is high gas fees. On Ethereum, transaction costs fluctuate based on network congestion. During peak usage—such as NFT drops or DeFi surges—gas fees can spike to tens or even hundreds of dollars.
Additionally, Ethereum’s average block time is around 13–15 seconds, which can lead to slower confirmations when the network is busy.
On the other hand, BEP-20 offers:
- Lower transaction fees: Typically just a few cents
- Faster block times: Around 3 seconds per block
- Higher transaction throughput: Up to 100+ transactions per second
These features make BEP-20 ideal for microtransactions, frequent trading, and yield farming strategies where minimizing costs is crucial.

How to Buy and Trade ERC-20 and BEP-20 Tokens
Buying and trading these tokens is straightforward if you follow best practices:
Choose a Reliable Exchange
- For ERC-20 tokens, use exchanges with deep Ethereum integration like Coinbase or OKX.
- For BEP-20 tokens, Binance offers seamless access due to its native connection with BNB Chain.
- Create and Verify Your Account
Complete KYC (Know Your Customer) verification to unlock full trading features. - Deposit Funds
You can deposit fiat currency (via bank transfer or card) or transfer existing cryptocurrency from a wallet. - Buy or Trade Tokens
Search for your desired token (e.g., USDT or CAKE), select the appropriate trading pair, and execute your order. Withdraw Safely
When moving tokens off-exchange:- Use a compatible wallet: MetaMask or Trust Wallet for both standards
- Double-check the network: Select “Ethereum” for ERC-20 or “BNB Chain” for BEP-20
- Never send tokens using the wrong network
Frequently Asked Questions (FAQ)
Q: Can I use the same wallet for both ERC-20 and BEP-20 tokens?
A: Yes. Wallets like MetaMask and Trust Wallet support both standards—but you must manually add the BNB Chain network to use BEP-20 tokens.
Q: Are ERC-20 and BEP-20 tokens interchangeable?
A: Not directly. However, you can bridge them using tools like the Binance Bridge or third-party cross-chain services.
Q: Which is better: ERC-20 or BEP-20?
A: It depends on your needs. Choose ERC-20 for maximum compatibility and security; choose BEP-20 for lower fees and faster transactions.
Q: Do I pay fees in the token I’m transferring?
A: No. On Ethereum, you pay gas in ETH; on BNB Chain, fees are paid in BNB—regardless of the token being sent.
Q: Is BEP-20 less secure than ERC-20?
A: While Ethereum uses a more decentralized consensus model, BNB Chain remains secure due to its hybrid design and active validator set. However, decentralization trade-offs exist.
Q: Can one token exist as both ERC-20 and BEP-20?
A: Yes. Many projects issue wrapped versions of their tokens on multiple chains. For example, USDT exists as both an ERC-20 and BEP-20 token.
Bonus: Understanding Other Token Standards
While ERC-20 and BEP-20 dominate the fungible token space, others serve unique purposes.
ERC-721: The NFT Standard
ERC-721 is the standard behind non-fungible tokens (NFTs)—digital assets that are unique and indivisible. Unlike ERC-20 tokens, no two ERC-721 tokens are alike.
This standard powers:
- Digital art marketplaces
- Collectibles like CryptoPunks
- In-game items and virtual real estate
- Token-gated access to exclusive content or communities
Developers use ERC-721 to create verifiable digital scarcity—a game-changer for ownership in the digital age.
Final Thoughts
Both ERC-20 and BEP-20 play vital roles in the crypto ecosystem. ERC-20 remains the gold standard for decentralization and broad support, while BEP-20 delivers performance and affordability for everyday users.
Your choice should depend on:
- Transaction frequency
- Budget for gas fees
- Desired level of decentralization
- Compatibility with target dApps or exchanges
By understanding these foundational standards, you position yourself to navigate the crypto landscape more confidently—making informed choices that align with your financial goals and technical needs.
