I'm not happy with panic in the runtime. Can we put mint only on successful creation and during the setting mint parameters - introduce another "ensure_*"? check on whether mint actually exist?

That is a fair point. I originally had this expect() inside the build() method before refactoring, where it was okay to panic while constructing genesis.
Given that add_mint can fail and we call it in the migration, I will have to make the mint an Option<MintId>
Let me revise.

Updated to make the mint an Option so it doesn't need to be created at genesis and we can avoid panic. The mint can be automatically created when setting capacity if it doesn't exist.

We agreed to print an error message in such cases. Don't we?

Single error message comment. Will be fixed later. LGTM |
