Binance, a leading cryptocurrency exchange, introduced its original blockchain, Binance Chain (now called BNB Beacon Chain), in 2017. In 2020, the platform expanded its ecosystem with Binance Smart Chain (BSC) to support advanced functionalities like smart contracts and Decentralized Finance (DeFi). While BSC’s BEP-20 token standard gained prominence, the original BEP-2 standard remains integral to Binance’s infrastructure. This guide explores BEP-2, its differences from BEP-20, and its role in the crypto landscape.
What Is BEP-2?
BEP-2 is a token standard governing the creation and management of tokens on BNB Beacon Chain. It defines rules for token issuance, transfers, and interactions, ensuring compatibility within Binance’s ecosystem. Inspired by Ethereum’s ERC-20, BEP-2 simplified token deployment but lacks smart contract functionality.
Key Features of BEP-2:
- Native to Binance Chain: Designed for fast, low-cost transactions.
- Consensus Mechanism: Combines Delegated Proof-of-Stake (DPoS) and Practical Byzantine Fault Tolerance (pBFT).
- Token Address Format: Begins with “bnb” (e.g.,
bnb1qxy2kgdygjrsqtzq2n0yrf2493...).

Binance Chain vs. Binance Smart Chain: A Breakdown
Binance Chain (BNB Beacon Chain)
- Launch Year: 2017
- Purpose: Facilitate decentralized trading via Binance DEX.
- Token Standard: BEP-2
- Consensus: DPoS/pBFT (energy-efficient).
Binance Smart Chain (BSC)
- Launch Year: 2020
- Purpose: Support DeFi, dApps, and smart contracts.
- Token Standard: BEP-20
- Consensus: Proof-of-Stake Authority (PoSA).
| Feature | BEP-2 (Binance Chain) | BEP-20 (BSC) |
|---|---|---|
| Smart Contracts | ❌ No | ✅ Yes |
| Address Format | bnb... |
0x... (EVM-compatible) |
| Transaction Fees | Low | None |
| Scalability | Limited | High |
BEP-2 vs. BEP-20 vs. ERC-20

Wrapped Tokens and BEP-2
Binance Chain hosts wrapped assets like BTCB (a BEP-2 version of Bitcoin). These tokens mirror the value of their underlying assets but operate within Binance’s ecosystem, enabling trading on Binance DEX.
FAQs
1. Can I use BEP-2 tokens for DeFi?
No. BEP-2 lacks smart contract support. For DeFi, migrate tokens to BSC as BEP-20.
2. How do I convert BEP-2 to BEP-20?
Use Binance Bridge or centralized exchanges like Binance to swap standards.
3. Is BEP-2 secure?
Yes. Its DPoS/pBFT consensus ensures robustness against attacks.
4. Which wallets support BEP-2?
Ledger Nano X, Trezor Model T, and Trust Wallet.
5. Why choose BEP-20 over BEP-2?
BEP-20 offers smart contracts, lower fees, and Ethereum Virtual Machine (EVM) compatibility.
Final Thoughts
While BEP-2 pioneered Binance’s tokenization, BEP-20 now dominates due to its versatility in DeFi and dApps. However, BEP-2 remains relevant for Binance DEX users and wrapped assets. Understanding both standards is crucial for navigating Binance’s multi-chain ecosystem.
