So I get a LN invoice, which has route_hints section.
I suppose it is the receiver telling me through which node he can surely receive a payment, right?
Who sets the fees? Is it that public node’s (XXX) fees for a channel YYY with the receiver to forward the payment to him?
"route_hints": [
{
"hop_hints": [
{
"node_id": "XXX",
"chan_id": "YYY",
"fee_base_msat": 100,
"fee_proportional_millionths": 3000,
"cltv_expiry_delta": 8
}]}],
