The list is manually maintainable. That is the only thing that would need maintenance, besides OS upgrades. I could pay you via lightning for assistance whenever you are done traveling, no rush or pressure.
I got something partially functional, kicking the tires on the API tonight. It's not as straightforward to use the electrum API as I thought.
Deploying & configuring could turn into a bigger challenge than I initially thought too.
100% possible. Not sure if I'll have enough time. I'll try to circle back on this 2 weeks from now.

@tech5, I got it to work on testnet. Here is a guide for you.
Pre-amble
The instructions are written to target testnet. You can get testnet bitcoins from a faucet on google. Remove
--testnet
from all commands after you have something functioning on your machine.I tested it with 1, 2 and 3 funded addresses on testnet. Note that the fee is static. I'm sure it'll work with infinite addresses.
1 Setup Server
- Install your fav linux distro (I did this on Ubuntu).
- Install python 3, optionally in a virtual environment
- Install electrum
- Install jq (Eg.
sudo apt-get install jq
)
Hopefully the above is easy enough for you. There are plenty of guides online for these.
Depending on your build, you may need to run the following.
export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python
Electrum will give you errors if you need this.
2 Configure Electrum
2 B - Daemon
Use Electrum docs & CLI to configure the daemon.
This will involve at the very least, setting a static port. Choose ports that aren't in use. No need to expose these ports externally, unless you know what you're doing.
electrum setconfig rpcport 7776 --offline --testnet
And mainnet, change the port to 7777.
2 - B Use Electrum UI to Setup your Wallet
electrum --testnet
Follow the prompts to setup your wallet with a password. Import the private keys you have into the wallet using the UI. Shut down the UI.
3 Run the Daemon
electrum daemon -d --testnet
4 Configure your Environment
export FEE=0.00001 # in BTC export DEST_ADDRESS=tb1qun6lw4f6mdqy97q373gs75m00etdklyrjjs2h2 export PASSWORD=pass export WALLET=~/.electrum/testnet/wallets/default_wallet_testnet
5 Load the wallet
electrum load_wallet -w $WALLET -W $PASSWORD --testnet
6 Get Addresses with Balances, Sweep & Broadcast
Run the following. It will list the addresses with balances, pull out the private keys, format them ready for the sweep command, prepare and sign a transaction, then broadcast it.
electrum listaddresses --funded -w $WALLET --testnet | electrum getprivatekeys - -w $WALLET -W $PASSWORD --testnet | jq -c | sed 's/[^a-zA-Z0-9:]/ /g' | electrum sweep - $DEST_ADDRESS --testnet -f $FEE | electrum signtransaction - -w $WALLET -W $PASSWORD --testnet | electrum broadcast - --testnet
7 Schedule
Add the command in step 5 to a cron schedule. So long as the electrum daemon and the wallet is unlocked the command will work.
8 Reboot
Run the commands from 3, 4 and 5 on startup of the server. Alternatively, you can run them before each command, but you would need to shut down the daemon if you did that.

Wow that’s awesome!! I will give it a try. Thank you for sharing!
