What Are ERC20 Tokens?
ERC20 tokens are the backbone of Ethereum-based crowdfunding and decentralized applications (dApps). Built on the Ethereum blockchain, these utility tokens follow a standardized protocol (ERC20) that ensures interoperability across wallets, exchanges, and smart contracts.
Key Characteristics:
- Smart Contract-Based: Each token operates via Ethereum smart contracts.
- Interchangeable: Fully fungible, meaning one token is equal in value to another.
- Widely Adopted: Compatible with major crypto exchanges like Binance and Coinbase.

Why Develop an ERC20 Token?
5 Compelling Reasons:
- Simplified Crowdfunding: Launch ICOs/IDOs effortlessly.
- Low Deployment Cost: No need to build a separate blockchain.
- High Liquidity: Easily tradable on exchanges.
- Security: Inherits Ethereum’s robust security framework.
- DApp Integration: Powers decentralized apps (e.g., Uniswap, Chainlink).
How to Create an ERC20 Token: Step-by-Step
Step 1: Define Token Parameters
- Name/Symbol: (e.g., "MyToken"/"MTK")
- Decimal Places: Typically 18 (like ETH).
- Total Supply: Fixed or dynamic (e.g., 1 million tokens).
Step 2: Write the Smart Contract
Use Solidity to code the contract with these mandatory functions:
function totalSupply() public view returns (uint256);
function balanceOf(address _owner) public view returns (uint256);
function transfer(address _to, uint256 _value) public returns (bool);Step 3: Test on Ethereum Testnets
- Deploy on Ropsten or Goerli.
- Verify via Etherscan.
Step 4: Deploy to Mainnet
- Use Remix IDE or Truffle.
- Pay gas fees in ETH.
Step 5: List on Exchanges
Apply to platforms like:
- OKX
- KuCoin
Essential Features of ERC20 Tokens
| Feature | Benefit |
|---|---|
| Mintable/Burnable | Adjust supply dynamically |
| Transfer Lock | Prevent unauthorized transactions |
| Tax Mechanism | Charge fees per transaction |
FAQs
1. How much does it cost to create an ERC20 token?
Deployment costs range $500–$3,000, depending on gas fees and complexity.
2. Can I update my smart contract after deployment?
No—smart contracts are immutable. Always audit code beforehand.
3. What’s the difference between ERC20 and BEP20?
ERC20 runs on Ethereum; BEP20 on Binance Smart Chain (cheaper transactions).
