ERC-20 vs BEP-20: Key Differences and Use Cases

In the world of cryptocurrency, token standards define how digital assets are created and function on a blockchain. Two of the most prominent standards are ERC-20 and BEP-20, each with distinct characteristics and use cases. Understanding their differences is essential for developers, investors, and users navigating the crypto landscape.

What Are ERC-20 and BEP-20 Tokens?

ERC-20 and BEP-20 are technical specifications that govern the behavior of tokens on their respective blockchains. They ensure compatibility across wallets, exchanges, and decentralized applications (DApps).

ERC-20 is the dominant standard on the Ethereum blockchain, enabling the creation of fungible tokens. BEP-20 serves a similar purpose on Binance Smart Chain (BSC), offering enhanced speed and lower transaction costs.

Core Similarities

Both standards share fundamental features:

• Fungibility (each token is identical and interchangeable)
• Smart contract compatibility
• Standardized functions for transfers, balances, and approvals

ERC-20 Token Standard: The Ethereum Foundation

ERC-20 tokens form the backbone of Ethereum's ecosystem, powering everything from decentralized finance (DeFi) to non-fungible tokens (NFTs).

Historical Background

Proposed by Fabian Vogelsteller in 2015, ERC-20 became official as Ethereum Improvement Proposal 20 (EIP-20) by 2017. Its standardization revolutionized token creation by providing a consistent framework for developers.

Technical Specifications

ERC-20 tokens utilize these core functions:

• totalSupply(): Returns the total token supply
• balanceOf(): Checks an address's token balance
• transfer(): Moves tokens between addresses
• approve(): Authorizes third-party spending
• allowance(): Checks approved spending limits
• transferFrom(): Enables delegated transfers

Primary Applications

ERC-20 tokens facilitate numerous use cases:

• DeFi protocols (lending, borrowing, trading)
• Initial coin offerings (ICOs)
• Stablecoins (USDT, USDC)
• Governance mechanisms
• Utility tokens for platform access

Major ERC-20 tokens include Tether (USDT), USD Coin (USDC), and Shiba Inu (SHIB). Even traditional financial companies like PayPal have entered the space with their own ERC-20 stablecoins.
