I guess the only issue is setting "no expiry", as well as anytime after January 19th 2038, it may fail if it's not represented as a bigint or a string...

Would a string work?

JavaScript uses a 64-bit floating-point number to represent dates. Jan 19, 2038 shouldn't be affected with use of number.

Yes a string would work, but would have to be converted to number elsewhere. If your only issue was the 32-bit overflow, would be good to keep as number.

Okay, let's make it a number, I'm convinced since the max safe integer in microseconds is 2255.

Can we document that it must be a SafeInteger? Because I guess the bounds are still the same problem anyways, where the number could be put in here negative, and that would also fail.

For a future update let's add a function that we can use to verify isUnsignedInt which would verify the bounds 0-> Number.MAX_SAFE_NUMBER. Then we won't get weird float values, and we can add it more places to provide better help with it.

accountSequenceNumber?: AnyNumber;
};
