Hi
I am going to open a online store and I have to test the bitcoin api, therefore I do need this feature sending unconfirmed transaction (create fake transactions)
Brainwallet is not working for me.
There is a program named BTCtxGen which is for sale, but seems to be a fake.
Is there somebody who can help me please.
Fairly confident that in your case you want to test/debug your system using the testnet not the mainnet. Sounds like you want "real" transactions, but in a no risk environment
