I have been working with offlineTransaction from BTCurious. The transaction I generated did not work through BTC Sender @
http://bitsend.rowit.co.uk/Is this site still working?
It appears that BTC Sender sends the transaction in the URL query string, which limits the length of the transaction string. This is another problem I am having; the transaction gets cutoff and the site does not post back.
I am trying to find a way to verify that the offlineTransaction I generated is valid. I tried generating the same transaction using Electrum and outputting the transaction. They were not the same length and it did not work on BTC Sender either. Even when I used an account that resulted in a short enough transaction string.
Fortunately, my BTC accounts were not adversely affected.
I like the Javascript approach for portability and ease of use.
I would really like to contact BTCurious since he authored the code.
Any suggestions?
Thanks.
