Content request

Hello, I am trying to practice with Substrate and was looking for the pallet associated with this mint-token tutorial

However, the link to the pallet goes to an outdated + archived version.

I am having a lot of errors that I am unable to debug because of the conflicting documentation and associated code in the outdated repo.

Are you willing to help with this request?

Yes!

@sacha-l , I did a quick sanity check and the old example (v3) does compile. How much work would it be to update/create a new version of the example? I thought at first we might be able to just swap out Cargo.toml files to get new dependencies, but it seems that there's a little more to it than that. If it's too much effort, don't sweat it. I'm just checking in case you know some simple fix to get this working again.

It wouldn't be that much work, though we would need to create a new home for example pallets like that in our docs org. Right now, as @anishnaik points out the mint-token pallet lives in a read-only archived repo.

That said, as I'm looking into this I question the actual value that this guide provides. I liked it originally because its meant to be an initiation for new comers and the simplicity of what it does makes it a good starting point for complete beginners: just using a storage map to map accounts to some quantity of type Balance. And users learn to include a minting and transfer function. However, I fear that its simplicity may be misleading and raise questions (e.g. the T::Balance type).

I suggest either we rework it as is (and possibly make it more of a tutorial) or rewrite the guide completely to focus on one or the other between:

• Basic patterns for using storage maps and their APIs
• Or, using different Balance and Currency configurations to handle token minting

What do you think?

@sacha-l thank you for your response. I think this is a good tutorial for people who are migrating from a different chain like Ethereum. The idea of tokens is familiar to people from other ecosystems and this tutorial/guide can aid in providing that bridge. I do believe that an additional level of complexity would help in making improvements to this tutorial worthwhile. A full "ERC20-like" tutorial would be cool. Additionally the T::Balance aspect threw me off but explanations of that kind of stuff is what will help newcomers understand the nuances of Substrate development. The interoperability of various pallets is something I think should be touched upon more in the documentation (but that besides the point 😄).

Have you had a look at this tutorial: https://docs.substrate.io/tutorials/smart-contracts/build-a-token-contract/ It uses ink! and the contracts pallet, bu† you might find it interesting to try.
