What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
