If you add TotalSupply in this PR, just linking this PR as well for the docs: #2661

[moul]

can we stop using the term "airdrop" for this feature (PR title, and a unit test having the term in the title); this PR isn't an airdrop checker, but a balance checker.

[moul]

check comments.

[notJoon]

@moul I've made modifications like this, what do you think? I've modified it to exclude the total supply and only provide the balance inquiry function for specific addresses.

Looks good; we can make the rendering better in the next iteration.

[Kouteki]

If Jae can't review this PR by EOD, let's merge it tomorrow.

We've reduced complexity, there shouldn't be anything in it that can't be rolled back easily.
