    OpenZeppelin Contracts is a library for secure smart contract development.

    • In the next step of my journey, I went to Github to see what other people were building. I didn't fine much. My heros [OpenZeppelin](https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/interfaces) don't seem to have any examples in their repository. Github's search yielded no results. Some Google searches finally did land me on two repositories. One is [an implementation of ERC-5114](https://github.com/TeamSHARKZ/soulbound) - horray!. The other one one of those traditional [awesome lists](https://github.com/attestate/awesome-soulbound-tokens). Great resource and introduced me to a standard I previously missed, [ERC-4973](https://eips.ethereum.org/EIPS/eip-4973). Of course, having completely missed a token reinforced how easy it is to miss something obvious along the way and encourages me to reach out and ask the community for more information.
