What is BEP20? The Binance Smart Chain Token Standard

BEP20 is the token standard for Binance Smart Chain (BSC) that enables developers to create digital assets and smart contracts, similar to Ethereum's ERC20 but with faster transactions and lower fees.

🔑 Key Characteristics of BEP20 Tokens

✅ Compatible with ERC20 - Works with Ethereum tools with minor adjustments
✅ Low transaction fees - Average $0.05-$0.30 per transaction
✅ Fast block time - 3-second block confirmation vs Ethereum's 15s
✅ Dual-chain support - Can operate on both BSC and Binance Chain

🛠️ Technical Structure

All BEP20 tokens must implement these mandatory functions:


// Required functions

function totalSupply() public view returns (uint256);

function balanceOf(address tokenOwner) public view returns (uint256);

function transfer(address to, uint256 tokens) public returns (bool);

function approve(address spender, uint256 tokens) public returns (bool);

function allowance(address tokenOwner, address spender) public view returns (uint256);

function transferFrom(address from, address to, uint256 tokens) public returns (bool);
