Still wondering how Poloniex can create transactions that are never broadcast to the network.
Is there an issue with their CLAM client?
How do they fix the problem?
And why is this ongoing?
Probably a security thing.
Not sure on CLAM but
createrawtransaction
signrawtransaction
sendrawtransaction
Are separate commands enabling the creation of a valid transaction but delay broadcast to suit needs.
Maybe of interest.
