Introduction
Binance developed its own blockchain ecosystem to support token creation, smart contracts, and decentralized applications. This guide explains the critical differences between BEP2 (Binance Chain) and BEP20 (Binance Smart Chain) token standards, their use cases, and how to interact with them safely.
Overview of BNB Chain
The BNB Chain is a unified blockchain system comprising:
BNB Beacon Chain (formerly Binance Chain)
- Handles governance (staking, voting) via BEP2 tokens.
BNB Smart Chain (BSC) (formerly Binance Smart Chain)
- EVM-compatible, supporting BEP20 tokens and smart contracts.

Key Differences Between BEP2 and BEP20
| Feature | BEP2 (Binance Chain) | BEP20 (Binance Smart Chain) |
|------------------|----------------------------|-----------------------------|
| Chain Type | Native chain (no smart contracts) | EVM-compatible (smart contracts) |
| Address Format | Starts with bnb... | Starts with 0x... (like Ethereum) |
| Memo Required | Yes | No |
| Use Case | Trading, governance | DeFi, dApps, token creation |
What Is Binance Chain (BEP2)?
- Purpose: Facilitates fast trading and asset issuance.
- Token Standard: BEP2.
- Native Token: BNB (used for fees).
Tip: Store BEP2 tokens in wallets like Trust Wallet or Ledger.
What Is Binance Smart Chain (BEP20)?
- Purpose: Enables DeFi, NFTs, and smart contracts.
- Token Standard: BEP20 (compatible with ERC20).
- Advantages: Low fees, Ethereum interoperability.
👉 Compare BSC’s gas fees to Ethereum’s.
How to Transfer Tokens
BEP2 to BEP20 Conversion
- Binance Exchange: Use the built-in swap function.
- Manual Bridge: Via the BNB Chain bridge (requires memo for BEP2).
Critical Safety Notes
- Never send BEP20 tokens to an ERC20 address (permanent loss).
- Always verify the network (e.g., BSC vs. Ethereum) before transferring.
FAQs
1. Can I use the same wallet for BEP2 and BEP20?
Yes, but addresses differ. BEP2 uses bnb..., while BEP20 uses 0x....
2. Which chain is better for DeFi?
BEP20 (BSC) supports DeFi protocols like PancakeSwap.
3. Are BEP20 tokens cheaper than ERC20?
Yes—BSC transactions cost a fraction of Ethereum’s gas fees.
Conclusion
- BEP2: Ideal for trading and governance.
- BEP20: Best for DeFi and smart contracts.
Always double-check addresses and networks to avoid irreversible mistakes.
