Good work.

Reviewed lockup file only. If you agree, I can add similar changed to Merkle Instant in #402. I may have made some extra changed than the comments below so if you disagree with anything, I will revert them.

@smol-ninja thanks for the review, i responded to your comments, once we settle on all of them i'll start reviewing the PR you created

[smol-ninja]

@andreivladbrg instead of reviewing #402, you can pick whatever we agreed on in above comments. It has other changes too which we may not need anymore. There are additional changes which you may like.

Also, I only made changes to Lockup guide and not Merkle Instant so feel free to make similar changes to Merkle Instant guide.

so many fails, but we made it 💪

@smol-ninja could you approve it if it looks good now?

[smol-ninja]

Yeah 💪
