Idk if we want to commit this...

[hariria]

can we stub the values

[affinity-matrix]

We can stub, yeah. This API key is a default but I can understand the concern.

[hariria]

One nit on linting: i think this is using tabs, can we switch to two spaces to be consistent with the rest of the repo?

[affinity-matrix]

ah, yeah. I thought I ran pnpm fmt but I may have also made an assumption about how it works.

[hariria]

Nit: rm, we don't need this

We can probably replace this with one script that uses tsx to execute. That way we don't need to transpile to javascript. Something like

Suggested change

	"build": "tsup",
	"start": "node dist/index.js",
	"dev": "tsup --watch",
	"clean": "rimraf dist",
	"download": "tsx index.ts",
	"lint": "biome check .",
	"fmt": "biome check . --write",

Also need lint and fmt scripts

[hariria]

Can remove

I'm kind of confused why this caused so many lock changes, can we just double check maayan's example with x-chain accounts is using the same versions as this?

[affinity-matrix]

Yeah, this was confusing for me as well. I could be wrong but I think it's because I forgot to pull main before starting this branch. I rebased from main to end up with this.

This is definitely much simpler, but the error output when user neglects to provide env vars is much less intuitive:

/Users/krbn/Source/examples/node_modules/.pnpm/@aptos-labs+ts-sdk@5.1.1_got@11.8.6/node_modules/@aptos-labs/ts-sdk/src/core/accountAddress.ts:385
    if (input.startsWith("0x")) {

Oh, we also have these issues with fmt:

@hariria I'm not familiar enough with the CI process to know how to best fix this. However, now I recall this is why my PR ended up with so many changes to the pnpm-lock file:

 Failure reason:
  specifiers in the lockfile ({}) don't match specs in package.json ({"@biomejs/biome":"2.2.4","tsx":"^4.20.5","typescript":"^5.9.2","vitest":"^3.2.4","@aptos-labs/ts-sdk":"^5.1.1","@shelby-protocol/sdk":"^0.0.4"})
Error: Process completed with exit code 1.

I had regenerated the file with pnpm -w install --lockfile-only
