ERC20 tokens are the most popular type of tokens on Ethereum. They can represent fungible assets like company shares, virtual currencies, vouchers, etc..
In this ERC20 token tutorial, I will walk you through the specification of ERC20. We will go through all the functions of the specification, including the transfer functions:
- simple transfer with transfer()
- delegated transfer with approve + transferFrom()
For delegated transfers I will give you a practical example by explaining how decentralized exchanges (DEX) transfer tokens with approve and transferFrom.
If you are a developers who want to understand how erc20 work and how you can transfer erc20 in your smart contract, this video is for you :)
