Hi there! Every now and then I look around for info on 0 fee transactions - nothing other than an intense personal curiosity. But to my (limited) knowledge, there isn't any more any wallet than can let you pay 0 fees so I'm very intrigued: how did you do it?

I can sometimes send txs as low as 3 sats per byte but never actually zero. I do it to test the network and see if it will ever get confirmed if it just keeps rebroadcasting without intervention (such as accelerating services).

Anyway, since it seems to be a problem for you, I've submitted it for confirmation. Your second one should confirm on its own in a day or two...

If you don't mind sharing, I'd love to try a 0 fee trial spend myself!
