The async-payment user story I'm interested in exploring is a mobile user (not always connected) who wants to receive donations (no PoP) via a static invoice from another mobile user.

My understanding of how this could work:

The static invoice should contain a blinded route to the payment receiver via their LSP and an ephemeral public key that the payment sender will use to encrypt the last hop of a payment onion containing a keysend TLV. The LSP of the payment receiver must support store-and-forward of onion messages.
A payment sender builds a payment onion where the first hop is their LSP that supports trampoline payments, onion messages and async-payments. The first hop of the onion includes a TLV to indicate the payment should be held until triggered (with a async-payment nonce) and gives the blinded route to the payment receiver. The last hop of the onion is encrypted to the payment receiver's ephemeral public key and includes:

the keysend TLV payment secret
the amount being sent

CLN (openchannel, openchannel2)	LND (ChannelAcceptResponse)	Eclair	Description	Example plugin use cases	Include?	Reason

psbt, our_funding_msat		fundingAmount, psbt?	to add inputs/outputs

Coin selection for liquidity providers

Bitcoin Core's coin selection algorithms optimizes mostly for the following metrics:

keep a low utxo count by consolidating regularly
avoid creating a change output
when a change output is needed, use an amount equivalent to the payment (for privacy)

This doesn't match what liquidity providers need. Liquidity providers need to:

	$remoteport = bash.exe -c "ifconfig eth0 \| grep 'inet '"
	$found = $remoteport -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';

	if( $found ){
	$remoteport = $matches[0];
	} else{
	echo "The Script Exited, the ip address of WSL 2 cannot be found";
	exit;
	}

	#!/bin/bash

	shopt -s expand_aliases
	alias btc-cli='bitcoin-cli -datadir=.bitcoin'

	if [[ $# -lt 3 ]]; then echo "usage: $0 <rpcwallet-from> <rpcwallet-to> <maximum confirmations>" ; exit 1 ; fi

	FROM=$1
	TO=$2
	CONFIRMATIONS=$3
