BEP-20

What Is BEP-20

BEP-20 is a token standard on Binance Smart Chain (BSC), a blockchain platform created by Binance. Similar to Ethereum's ERC-20 standard, BEP-20 sets the rules and guidelines that tokens must follow to work on Binance Smart Chain. This standard ensures that tokens are compatible and can interact smoothly within the BSC ecosystem, allowing developers to create fungible tokens that can represent different assets.

The BEP-20 standard defines the basic functions that a token should have. These include how tokens can be transferred, how they can be approved for spending by others, and how to access information about the token, such as its name, symbol, and total supply.

What Is BEP-20 Used For

BEP-20 tokens have several key uses within the Binance Smart Chain (BSC) ecosystem:

Creating New Tokens 

Developers can create new tokens using the BEP-20 standard for various purposes. These tokens can be utility tokens, providing access to products or services, or stablecoins, which are tied to stable assets like the US dollar. By using the BEP-20 standard, developers ensure their tokens work with many wallets, exchanges, and applications within the BSC ecosystem.

Decentralized Finance (DeFi)

BEP-20 tokens are widely used in DeFi applications, which aim to recreate traditional financial systems like lending, borrowing, and trading in a decentralized way. Platforms like PancakeSwap, a decentralized exchange on BSC, let users trade BEP-20 tokens directly from their wallets without needing a middleman. Other DeFi applications, like yield farming and liquidity mining platforms, also use BEP-20 tokens to reward users for providing liquidity.

Payments

BEP-20 tokens can be used as a form of payment within the Binance Smart Chain network and beyond. Merchants and service providers can accept BEP-20 tokens for goods and services, making these tokens useful for cross-border payments and small transactions.

Staking and Governance 

Some BEP-20 tokens allow holders to participate in staking and governance activities. By staking their tokens, users support the network's security and operation and earn rewards in return. Governance tokens let holders vote on changes to the network, such as new rules or how funds from a decentralized treasury are used. This gives token holders a significant role in shaping the future of the project.

Interoperability

BEP-20 tokens can be transferred and used across different applications within the BSC ecosystem, allowing for smooth interaction between various decentralized applications (dApps). This is possible because of the widespread use of the BEP-20 standard and BSC's compatibility with Ethereum. Additionally, blockchain bridges enable BEP-20 tokens to be transferred to and from other blockchains, enhancing cross-chain functionality. 

Brief Background of the BNB Chain Ecosystem

The BNB Chain ecosystem has evolved significantly since its inception:

  1. In 2019, the BNB Chain (now BNB Beacon Chain) was launched, with BNB becoming its native token.

  2. In 2020, BNB Smart Chain (BSC) was created to address limitations of the BNB Beacon Chain, particularly in terms of smart contract functionality and scalability.

  3. In 2022, both chains were brought together under the BNB Chain ecosystem umbrella.

The two blockchains serve different purposes within the ecosystem:

  • BNB Beacon Chain: Uses the BEP-2 token standard and functions as a governance layer with staking and voting systems.

  • BNB Smart Chain (BSC): Offers smart contract functionality, uses the BEP-20 token standard, and is EVM-compatible. It supports DApps, DeFi services, and multi-chain operations.

BSC operates independently alongside BNB Beacon Chain, not as a layer 2 solution. Its EVM compatibility allows easy porting of Ethereum projects and integration with tools like MetaMask. 

The BNB Chain Fusion, announced in late-2023, aims to retire the BNB Beacon Chain and transfer its core functionalities to BSC. The migration has been taking place throughout Q2 and Q3 of 2024.
