In this chapter, we covered the most popular ERC token standards – ERC-20 and ERC-721. We set up a Truffle project and developed an ERC-20 token called MYERC20Token. We also implemented the ERC-20 interface with many additional token functions. Finally, we continued to implement ERC-721 for a digital art non-fungible token, which we used for an art trade.
In the next chapter, we will continue our learning journey and start to learn about Ethereum tools and unit tests.
