Introduction to BEP-20 Tokens
The BEP-20 token standard is an extension of ERC-20, Ethereum’s most widely adopted token protocol. Designed for the Binance Smart Chain (BSC), BEP-20 tokens enable diverse crypto assets to operate seamlessly within the BSC ecosystem. The acronym BEP stands for Binance Smart Chain Evolution Proposal, reflecting its role in advancing Binance’s blockchain capabilities.
BSC was launched by Binance in May 2020 to complement its existing blockchain. Unlike the Binance Chain, which prioritizes speed for trading, BSC integrates smart contract functionality—unachievable with the older BEP-2 standard—without compromising performance.
Key Features of BEP-20 Tokens
- Compatibility: Integrates with BSC’s framework, supporting DeFi and dApp development.
- Flexibility: Allows creation of tokens pegged to crypto/fiat, securities, or stablecoins.
- Interoperability: Fully compatible with ERC-20 (Ethereum) and BEP-2 (Binance Chain) tokens.

How BEP-20 Tokens Work
Deploying BEP-20 tokens is streamlined due to their design as hybrids of BEP-2 and ERC-20. Conversions between standards use Binance Bridge or compatible wallets via:
- Peg-in: Locking native assets to mint BEP-20 versions.
- Peg-out: Redeeming BEP-20 tokens for original assets.
Examples of BEP-20 Tokens
Native Tokens:
- BNB (Binance Coin): BSC’s native currency.
- CAKE (PancakeSwap): A leading DeFi token.
Peggy Coins:
- BTCB: BEP-20 Bitcoin, backed 1:1 by BTC.
- ETH, ADA, USDT: BSC versions of Ethereum, Cardano, and Tether.
Quote from Binance:
"Peggy coins like BTCB track their native assets’ value. Lock 10 BTC to mint 10 BTCB; trade back anytime at parity."
Technical Breakdown of BEP-20
Shared Traits with ERC-20
- Supply & Balance: Defines maximum tokens and user holdings.
- Divisibility: Configurable decimal places (e.g., 18 for ETH).
- Transfers: Requires BNB for transaction fees (gas), rewarding BSC validators.
Unique Advantages
- Developer-Friendly: Simplified APIs for smart contracts.
- Cross-Chain: Movable between Binance Chain and BSC via standardized protocols.

FAQ: BEP-20 Tokens
1. What’s the difference between BEP-2 and BEP-20?
- BEP-2: Older Binance Chain standard; no smart contracts.
- BEP-20: BSC standard with smart contract support and ERC-20 compatibility.
2. Can I convert ERC-20 tokens to BEP-20?
Yes! Use Binance Bridge to swap ERC-20 tokens (e.g., ETH) for BEP-20 versions.
3. Why choose BEP-20 over ERC-20?
- Lower fees: BSC transactions cost less than Ethereum’s.
- Faster speeds: BSC processes blocks in ~3 seconds vs. Ethereum’s ~15.
4. Are BEP-20 tokens secure?
Yes, but always verify token contracts on BscScan to avoid scams.
5. What wallets support BEP-20?
- Trust Wallet
- MetaMask (with BSC network configured)
Conclusion
BEP-20 tokens merge the best of Binance and Ethereum ecosystems, offering low-cost, high-speed alternatives for token creation and DeFi innovation. Whether you’re a developer or investor, understanding BEP-20 unlocks opportunities in the BSC universe.
