Is there a way to create zero fee transaction anymore.The only way I knew was Blockchain.info and it seems they have removed it now.
PS: I need it for technical purpose.
If you really want to do it, and since I actually don't know any other way of doing this to be honest, you should try using Blockchain.info with the legacy version. AFAIK they still allow it.
But what's the point of a zero fee transaction anymore?
I'm pretty sure they still let you create 0 fee transactions on the beta wallet, but the last time I did one on there, it took half a day to confirm it. There really is no point unless you're low on money and need to pay somebody, but have no extra bitcoin to make the transaction fee. It's just too damn slow nowadays to make one of those, and besides, if it doesn't confirm the mempool just sends it back and you've done absolutely nothing.
