Missing valid_until field for setting transaction expiration in tonutils-go

[slashramin]

Hi,

According to the TON documentation and other SDKs (like TonWeb), there is typically a valid_until field that allows the user to specify the expiration time of a transaction. This is essential for creating timed transactions (e.g., a transaction that expires in 3 seconds).

However, I could not find any such field or method for setting a transaction's expiration in this package.

Would it be possible to implement this field or provide an alternative method to set the expiration for transactions in tonutils-go? This feature is available in other SDKs and would be a valuable addition here.

In other SDKs (e.g., TonWeb), the expiration time is set using the validUntil field, like:

validUntil: Date.now() + 1000 * 3 // Transaction expires in 3 seconds
Thank you for your work on this project!

Hi, this functionality is already exists, you can set valid until for wallet versions which are supports it, e.g v4, using: w.GetSpec().(*wallet.SpecV4R2) .SetMessagesTTL(seconds), spec type depends on wallet version
