This design choice ensures compatibility with Ethereum-based systems, allowing for seamless integration and interoperability of tokens between the two platforms. Such compatibility is particularly beneficial for users and developers who operate across both Binance and Ethereum ecosystems.

Core Functionalities and Automation

At its core, the BEP20 standard includes several functions that define the token’s behavior and capabilities. Functions like “totalSupply”, which returns the total number of tokens in a contract, and “balanceOf”, indicating the number of tokens in a specific user address, are fundamental to its operation. The “transfer” function allows users to transfer tokens, requiring the sender to own the tokens they wish to transfer. In contrast, “transferFrom” enables automated transfers by authorized persons or contracts, adding a layer of automation and flexibility. This is particularly useful for services that require recurring payments.

Enhanced Control and Transparency

Moreover, the “approve” and “allowance” functions are crucial for managing how many tokens a smart contract can withdraw from a user’s balance. This feature is essential in decentralized finance (DeFi) applications where users interact with various smart contracts. Additional details like “name”, “symbol”, and “decimal” are also part of the BEP20 token’s structure. These attributes provide essential information about the token, such as its identifiable name and symbol, as well as its divisibility determined by the decimal value. Notably, while symbols and decimals are optional in ERC-20 tokens, they are mandatory in BEP20 tokens. A unique aspect of BEP20 is the “getOwner” function, which identifies the owner of the token, further enhancing transparency and ownership tracking.

How Does BEP20 Token Work?

Step 1: Token Creation and Smart Contract Rules

BEP20 tokens operate on the Binance Smart Chain using a defined set of rules. Developers code these rules into smart contracts, which are automated agreements on the Blockchain. When a BEP20 token is created, the smart contract includes the token’s total supply and manages all transactions.

Step 2: Initiating Transactions

For a transaction to occur, a user initiates a transfer command through a decentralized application (dApp) or crypto wallet. This command calls the token’s smart contract functions like “transfer” or “transferFrom”, which securely move tokens from one address to another.

Step 3: Authorization and Automated Transactions

The “approve” function lets users allow others to spend a specific amount of their tokens, streamlining recurring and automated transactions. This function is key for transactions that require user permission or for setting up automatic payments.

Step 4: Transaction Verification and Recording

Every transaction is verified and recorded on the Blockchain. The Binance Smart Chain uses the Proof of Stake Authority (PoSA) consensus mechanism for this. Validators on the network approve transactions and add them to new blocks.

Because of PoSA, transaction fees are low, making BEP20 tokens cost-effective for users. These tokens aren’t just for simple transfers; they can represent anything from fiat currency equivalents to shares in a project.

The BEP20 standard has been a catalyst for innovation on the Binance Smart Chain, facilitating a growing ecosystem of digital assets and services. This flexibility has made them popular for fundraising, governance, and as rewards in dApps.
