Binance Chain (BC) and Binance Smart Chain (BSC) are at the core of the Binance ecosystem. As parallel yet distinct blockchains, BC and BSC each have their own native token standards – BEP2 and BEP20.
Despite their similarities, BEP2 and BEP20 tokens have different technical structures, capabilities, and ideal applications.
In this in-depth guide, we‘ll analyze the key differences between BEP2 vs. BEP20 across a range of categories. Whether you are looking to invest in, develop on, or leverage Binance Chain or Smart Chain, understanding these two standards is essential.
Origin and Evolution of Binance Chain and Smart Chain
First, let‘s look at the history and original goals of Binance Chain and Smart Chain.
Binance Chain was founded in 2019 by Changpeng Zhao, founder of Binance exchange. It was purpose-built to be a high performance blockchain for Binance DEX, allowing fast trading of crypto assets.
Binance Smart Chain emerged in 2020 as an EVM-compatible companion chain to Binance Chain. It enabled smart contract functionality and interoperability with the Ethereum ecosystem.
BSC was introduced to make up for Binance Chain‘s lack of smart contract support. This allowed the development of DeFi and dApp solutions to better compete with Ethereum‘s dominance in that area.
Below we can see the growth in adoption for BNB, the native token of both chains, over the years:

BEP2 Tokens Explained
The Binance Chain Evolution Proposal 2 (BEP2) standard is used to issue tokens on Binance Chain.
Some key facts about BEP2:
-
Over $xx billion in BEP2 tokens traded on Binance DEX in 2022
-
Used by yy million unique traders on Binance DEX per month
-
Native token is BNB, with $zz billion market cap
-
Other popular BEP2 tokens: XYZ, ABC, PQR
-
Enables seamless trading between crypto assets on Binance DEX
-
Limited use cases beyond trading due to no smart contract support
BEP2 leverages a Proof of Staked Authority consensus that enables fast settlement and minimal fees for Binance DEX trades.
However, the lack of smart contract capabilities severely limits what developers can build on BEP2 and Binance Chain. It is not well suited for complex DeFi and dApp solutions.
BEP20 Tokens Explained
The Binance Smart Chain Evolution Proposal 20 (BEP20) is the technical standard used for issuing tokens on Binance Smart Chain.
Some key statistics for BEP20 adoption:
-
Over $xx billion in BEP20 tokens issued on BSC
-
$yy billion worth of assets locked in BEP20 DeFi protocols
-
zz million transactions per day on Binance Smart Chain
-
Popular BEP20 tokens: PancakeSwap, Venus, BakerySwap, etc.
BEP20 provides full smart contract functionality to empower developers to build DeFi apps, utility tokens, NFTs, and more. It does this by extending the ERC-20 standard used on Ethereum.
The BEP20 standard coupled with fast transaction times and low fees has made BSC a popular hub for DeFi development, though concerns around centralization remain.
Comparing BEP2 and BEP20 Side-by-Side
Let‘s compare some of the key differences between the BEP2 and BEP20 token standards:
| Feature | BEP2 | BEP20 |
|---|---|---|
| Launch Date | 2019 | 2020 |
| Blockchain | Binance Chain | Binance Smart Chain |
| Consensus | Proof of Staked Authority | Proof of Staked Authority |
| Avg Block Time | 1 second | 3 seconds |
| Smart contracts | No | Yes (EVM-compatible) |
| Top Tokens | BNB, XYZ, ABC | PancakeSwap, Venus, BakerySwap |
| DeFi Apps | None | Hundreds |
| 2022 Daily Tx Volume | $xxx million | $yyy million |
| Total Value Locked | $0 | $zzz billion |
| Decentralization | Low (11 validators) | Moderate (21 validators) |
| Fee Model | Fixed native fees (~0.01 BNB) | Native gas fees |
Analyzing the table shows BEP20‘s advantages in terms of capabilities and adoption due to its interoperability with Ethereum and support for advanced use cases.
Now let‘s dive deeper on some of the differentiating factors between these two Binance token standards.
Lack of Smart Contract Functionality in BEP2
One of the biggest technical limitations of BEP2 is its lack of support for smart contracts…

A key advantage BEP20 has over BEP2 is its seamless connectivity to the broader Ethereum ecosystem. This is enabled by BEP20‘s extension of the ERC-20 standard…

Based on their distinct capabilities and limitations, here is an overview of when each token standard is most appropriate:
BEP2 Best Use Cases:
- Trading crypto assets on Binance DEX
- Making payments within the Binance ecosystem
- Simpler applications that don‘t require smart contracts
For example, the XYZ project utilizes BEP2 for its in-app payment solution because they only require simple token transfers without complex logic.
BEP20 Best Use Cases:
- Developing decentralized apps (DeFi, NFTs, metaverses, etc.)
- Token integrations across the wider blockchain ecosystem
- Accessing ample liquidity and community resources
For instance, the ABC protocol was built on BEP20 to leverage existing developer resources and Ethereum interoperability for its lending platform.
Conclusion
While BEP2 and BEP20 share some technical similarities, BEP20 provides far greater capabilities and flexibility for developers. Its support for smart contracts and Ethereum interoperability unlocks innovation in DeFi, utility tokens, NFTs, and other cutting edge use cases.
Meanwhile, BEP2 remains useful for straightforward trading and payments confined within Binance‘s ecosystem. Understanding these key differences allows matching each token standard to appropriate applications.
