Resolves #278

Context

  • Do not merge yet!

  • First we need a PR that properly merges blockfrost-gateway into this repository (with history), then the diff of this PR will become much smaller.

  • This temporary situation is to showcase the functionality in another demo video.

  • Once that’s done, we’ll merge all 3 PRs calmly.

To-dos

  • fix CI
  • the demo video (see here)
  • split into separate PRs: subtree-merge Gateway and this separately
