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.

Let's follow up with some bounds checks for parts like this.
maxGasAmount?: number; | ||
gasUnitPrice?: number; | ||
expireTimestamp?: number; |

Description
maxGasAmount, gasUnitPrice, expireTimestamp
properties should be represented asnumber
type.First,
bigint
causes serialization issues for dapps and wallets and second these property values fall within the JS number type range.https://aptos-org.slack.com/archives/C06BFEMLAKT/p1703193020312399
Next - once this PR lands, wallet adapter should be updated to use the new sdk version and types.
Test Plan
