thanks a lot, funds was back to the wallet. So now it is necessary to create a new transaction with the same inputs of the failed transaction, I think right?
Correct. My node's minfee sets it at roughly 5sat/vbyte.
{
"loaded": true,
"size": 53578,
"bytes": 78121044,
"usage": 280737632,
"maxmempool": 300000000,
"mempoolminfee": 0.00005346,
"minrelaytxfee": 0.00001000,
"unbroadcastcount": 0
}
You'll probably have to create a new transaction spending at least 5sat/vbyte for it to be relayed by the nodes.
My apologies for going off-topic but which RPC command gives you this listing? On a stock 0.21.0 I can get a "relaytxfee" field (which says 1 sat/vbyte by the way) if I use getnetworkinfo but that's the closest I could get.
