When exploring the world of cryptocurrency tokens, it's essential to understand the different standards that govern their creation and functionality. The most prominent among these are ERC20, BEP20, and TRC20. Each operates on a distinct blockchain network and offers unique features, benefits, and limitations. This guide delves into the specifics of these token standards, comparing their key aspects to help you make informed decisions in the crypto space.
Understanding Token Standards
A token standard is a set of rules and specifications that define how tokens are created, managed, and transacted on a particular blockchain. These standards ensure interoperability, security, and consistency across tokens within the same network. For developers, adhering to a token standard simplifies the process of creating new tokens, as they can build upon established protocols without reinventing the wheel.
ERC20: The Ethereum Standard
ERC20 is one of the most widely adopted token standards, primarily used on the Ethereum blockchain. ERC stands for Ethereum Request for Comment, and this standard has become the foundation for countless tokens in the crypto ecosystem. Most tokens listed on popular platforms like CoinMarketCap are ERC20-based, highlighting its dominance.
Key Features of ERC20
- Swift Transactions: ERC20 tokens benefit from quick transaction confirmations due to Ethereum's robust network.
- Global Acceptance: These tokens are recognized worldwide, offering high liquidity and revenue potential.
- Security: The Ethereum network minimizes the risk of contract breakage, ensuring secure transactions.
- Cost-Effectiveness: Developing ERC20 tokens is both affordable and time-efficient, making it accessible for many projects.
- Compatibility: ERC20 tokens can also be utilized on other networks like Binance Smart Chain (BSC) and TRON, enhancing their versatility.
How to Create an ERC20 Token
Creating an ERC20 token requires technical expertise in blockchain development and programming. The process involves writing smart contracts using Solidity, Ethereum's programming language. Key coding functions include:
totalSupply(): Returns the total token supply.balanceOf(): Checks the balance of a specific address.transfer(): Moves tokens from one address to another.approve(): Allows a spender to withdraw tokens multiple times up to a limit.allowance(): Returns the amount of tokens approved for spending.transferFrom(): Enables transfer of tokens on behalf of the owner.

BEP20: The Binance Smart Chain Standard
BEP20 is the token standard for the Binance Smart Chain (BSC), designed as an extension of ERC20. It inherits all the features of ERC20 while offering enhanced speed and lower transaction costs. BSC was created to support smart contracts and decentralized applications (DApps), making BEP20 a popular choice for developers.
Key Features of BEP20
- Cross-Chain Compatibility: BEP20 tokens can represent other cryptocurrencies like Bitcoin, Ethereum, and Litecoin, facilitating seamless transfers.
- Efficiency: BSC processes transactions faster and at a lower cost compared to Ethereum, making it ideal for high-frequency trading.
- Smart Contract Support: Developers can build DApps and complex smart contracts on BSC, leveraging BEP20's flexibility.
- Interoperability: BSC is compatible with Ethereum, allowing users to transfer ERC20 tokens at reduced fees and higher speeds.
How to Create a BEP20 Token
Creating a basic BEP20 token is straightforward, even for those with limited technical knowledge. However, developing a customized, feature-rich token requires expertise in blockchain programming. Key coding functions mirror those of ERC20, with additional elements like:
name(): Returns the token's name.symbol(): Returns the token's symbol.decimal(): Specifies the token's divisibility.
Professional developers can help tailor tokens to specific needs, ensuring security and functionality.
TRC20: The TRON Standard
TRC20 is the token standard for the TRON blockchain, modeled after ERC20. TRON was designed to address Ethereum's limitations, offering faster transaction speeds and lower fees. TRC20 tokens adhere to a set of rules that govern their issuance, transfers, and management within the TRON network.
Key Features of TRC20
- High Speed: TRON uses a Delegated Proof of Stake (DPoS) consensus mechanism, enabling faster block verification compared to Ethereum's Proof of Work (PoW).
- Low Fees: Transaction costs on TRON are significantly lower, making it cost-effective for users.
- Ethereum Compatibility: TRON's virtual machine supports Solidity, allowing developers to port Ethereum-based smart contracts easily.
- Specialized Wallets: TRC20 tokens are supported by dedicated digital wallets, enabling secure storage and transfers.
How to Create a TRC20 Token
Developing a TRC20 token involves creating a smart contract on the TRON blockchain. This requires familiarity with programming languages like Solidity and an understanding of TRON's ecosystem. Key functions include:
token name(): Defines the token's name.token abbreviation(): Sets the token's symbol.token precision(): Determines the token's decimal places.- Standard functions like
transfer(),approve(), andallowance().
Once deployed, TRC20 tokens can interact with other tokens and DApps on the TRON network.
Comparative Analysis: ERC20 vs. BEP20 vs. TRC20
| Basis | ERC20 | BEP20 | TRC20 |
|---|---|---|---|
| Algorithm | Proof of Work (PoW) | Proof of Stake Authority (PoSA) | Delegated Proof of Stake (DPoS) |
| Gas Fees | High ($30+) | Low ($0.4ā$15) | Moderate ($15+) |
| Network | Ethereum | Binance Smart Chain | TRON |
| Address Style | 0xbd7eā¦ | 0x0fde7eā¦ | T4zf14ā¦ |
| Block Speed | 15 seconds | 3 seconds | 3 seconds |
| Security | High | Low | Moderate |
Key Takeaways
- ERC20 offers high security and global acceptance but comes with elevated transaction fees.
- BEP20 provides low costs and fast processing, ideal for developers prioritizing efficiency.
- TRC20 balances speed and affordability, leveraging TRON's DPoS consensus for optimal performance.
