There was a problem hiding this comment.
This look to me like the overide of the mint() psp34:InternalImpl.
This chapter was about how to create custom trait, while the code is just overriding OB mint function.
I feel the best would be to delete this whole step in the code and in the doc merge chapters
- Custom Trait
- PayableMint trait
