Hey this looks great! Just take a look at my recent commit here and update your tests if you wouldn't mind!

Let's just tighten up the packing/unpacking and this should be good to go!

This looks great! I noticed a few tiny things, and then we can wrap it.

Also might have to refresh the lockfile with a pnpm i.

When I run pnpm test locally in project root, it gives an error:

> @solana/[email protected] test /Users/qiweiyang/GitHub/solana-program-library/single-pool/js/packages/classic
> sed -i '1s/.*/{ "type": "module",/' package.json && NODE_OPTIONS='--loader=tsx' ava ; ret=$?; sed -i '1s/.*/{/' package.json && exit $ret

sed: 1: "package.json": extra characters at the end of p command
sed: 1: "package.json": extra characters at the end of p command

not sure if this will pass in ci

I think what's happening is when you're merging master into your branch to resolve the merge conflicts, your lockfile is getting bungled.

I can clone your branch and run pnpm i in the root and it seems to resolve the lockfile problems. Then I immediately can run pnpm test in the Token Group JS package and it works no problem!

Maybe just try pnpm i in the root and commit the lockfile?

Thanks for shippin' this in!
