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:

  1. balanceOf(address): Returns the token balance of a specific address.
  2. transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
  3. approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
  4. allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
  5. User1 owns 500,000 ABC Tokens.
  6. User2 wants to buy 100 ABC Tokens from User1.
  7. User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
  8. User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
  9. The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
