In the early days of cryptocurrencies, creating a blockchain project required developing an entirely new blockchain—akin to reinventing the wheel. Today, Ethereum's ERC20 standard enables anyone to create tokens without building a dedicated blockchain. This innovation has led to thousands of ERC20 tokens now in circulation.
This article explores:
- What the ERC20 standard is and how it works.
- The definition and utility of ERC20 tokens.
- Key comparisons with alternatives like TRC20.
Understanding the ERC20 Standard
ERC20 (Ethereum Request for Comment 20) is a technical standard for token creation on Ethereum. It provides developers with a set of rules to build smart contracts for fungible tokens without needing an independent blockchain.
Core Features of ERC20 Tokens
Optional Fields:
- Token Name: Customizable label (e.g., "ArzdigitalGame").
- Symbol: Abbreviation (e.g., "AGM").
- Decimals: Determines divisibility (e.g., 2 decimal places allow units as small as 0.01).
Mandatory Fields:
- Total Supply: Maximum token quantity.
- BalanceOf: Tracks user token holdings.
- Transfer: Moves tokens between addresses.
- TransferFrom: Allows delegated transfers (e.g., for trading).
- Approve/Allowance: Validates transactions based on available balances.
Popular ERC20 Tokens
Examples include:
- Tether (USDT)
- Wrapped Bitcoin (WBTC)
- Chainlink (LINK)
- SHIBA INU (SHIB)
These tokens leverage Ethereum’s EVM compatibility and can be stored in any Ethereum-supported wallet.
Why ERC20 Matters
- Interoperability: Ensures seamless token exchanges across platforms.
- Cost Efficiency: Eliminates the need to build a blockchain from scratch.
- Global Standard: Simplifies integration with wallets/exchanges.

ERC20 Alternatives
| Standard | Blockchain | Key Traits |
|----------|------------|------------|
| BEP20 | Binance Smart Chain | Low fees |
| TRC20 | Tron | Fast transactions |
| SPL | Solana | High scalability |
| Native Assets | Cardano | Proof-of-Stake |
ERC20 vs. TRC20
| Metric | ERC20 | TRC20 |
|--------|-------|-------|
| Speed | ~15 min/transaction | ~3 min/transaction |
| Fees | Higher (ETH gas) | Lower |
| Address | Starts with 0x | Starts with T |
| Security | High | High |
FAQ
How long do ERC20 transactions take?
~5 minutes (12 confirmations required).
What’s the cost per transaction?
Variable; depends on Ethereum’s gas fees (track here).
Can anyone create an ERC20 token?
Yes, but tokens require value propositions (e.g., utility in a project).
Which programming language is needed?
Solidity (Ethereum’s native language).
Key Takeaways
- ERC20 democratized token creation by removing blockchain development barriers.
- Tokens like USDT and SHIB thrive on Ethereum’s security and network effects.
- Alternatives (e.g., TRC20) compete via speed/fee advantages but lack Ethereum’s ecosystem depth.
