Summary
In this chapter, we covered the most popular ERC token standards – ERC-20, ERC-721, and ERC-1155. 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. Next, we continued to implement ERC-721 for a digital art NFT, which we used for an art trade. Finally, we covered another popular NFT token standard, ERC-1155, and walked through the OpenZeppelin ERC-1155 contract to get a better understanding.
In the next chapter, we will continue our learning journey and start to learn about Ethereum tools and unit tests.
