Title: Getting the txn size before sending?
Post by: Anonymous on August 27, 2011, 05:29:07 PM
I was wondering if there was a way for me to calculate the transaction fee of a transaction before sending it. I know that I pay per KB, so how can I calculate how large a transaction will be before sending it.
Thanks,

You need to know what transactions your new transaction will use
Not easy but possible if you know how the standard client choses them
