A Step-by-Step Guide to Token Creation
The most widely used tokens (blockchain currencies) today are ERC20 tokens issued on the Ethereum blockchain. ERC20 can be thought of as a smart contract that tracks ownership balances and enables token transfers. If your token's smart contract adheres to the ERC20 standard, it qualifies as an ERC20 token.

Key Components:
- Smart Contract: Records account balances and transfer functions.
- Test Networks: Use Ethereum testnets like Rinkeby for deployment trials.
- Wallet Setup: Configure MetaMask for Rinkeby and acquire test ETH via faucets.
Deployment Process:
- Develop your contract using platforms like Remix IDE.
Configure parameters:
- Token supply (e.g., 21,000,000 HYT)
- Token name/symbol
- Decimal places
- Deploy via Web3/MetaMask and verify balances.
Why Blockchain Tokens Differ:
- Interoperability: ERC20 tokens can be freely traded on exchanges vs. closed systems like Q币.
- Regulatory Note: Many jurisdictions impose investor protection measures on token offerings.
What Is ETB?
ETB (Ether) is Ethereum’s native cryptocurrency:
- Powers transactions and smart contracts.
- Ranked as the #2 cryptocurrency by market cap (after Bitcoin).
- Launched in 2015 as part of Ethereum’s decentralized application platform.
ERC-20 Standard Explained
Overview:
- Proposed in 2015 by Fabian Vogelsteller.
- Defines rules for token behavior on Ethereum (transfers, balances, supply).
Technical Functions:
transfer(): Moves tokens between addresses.balanceOf: Returns account balances.- Metadata: Token name/symbol/decimal standardization.
Adoption Impact:
- Enabled 160,000+ tokens by 2023.
- Facilitates ICOs, governance tokens, and DeFi protocols.
Exception: Ether (ETH) predates ERC20, leading to wrapped ETH (WETH) for compatibility.
