I've seen these on mempool.space - for instance this block has a fee range of .17 to 100 sats/vbyte.
Which wallets are people creating these in? At one point Sparrow, for one, didn't allow that. But obviously things may be changing, or have changed already.
Oops, forgot the block - it's this one - https://mempool.space/block/000000000000000000020a852eec4de2f78f03b495276a0abb6d62ea726e9c34.
The fee range is between 0.20 - 130 sat/vB.
Sparrow does allow for fees lower than 1 sat/vB. You just need to connect it to a Bitcoin node that has a lower minrelaytxfee 😎

For some reason I always have peers that broadcast transaction with lower fees. Without even hardcoding any. You could force the connection to some specific peers if you want to make sure. I think transactions in the mempool are not rebroadcasted by default.

Yeah the units are a bit weird: BTC/kvB.
This is my conf. The second one is to raise data limits already, but this is more controversial nowadays.
# relay settings # min relay fee of 0.01 sat/vB minrelaytxfee=0.0000001 datacarriersize=1000000I now set mine to
# in BTC/vkB, so 0.1 sat/vB is 0.000001 minrelaytxfee=0.000001and successfully made a transaction with 0.3 sat/b in Electrum!

must have addnode parameters in bitcoin.conf to connect to these peers: https://gist.github.com/ottosch/1aa7ef9a8a3971c19ef8a148931d4f49
Some miners don't pick transactions under 1 sat/vb.
You can check if at least it propagated through the network. Checking https://mempool.space or similar.
Thank you. Thanks much
