Balance of Satoshis

Commands for working with LND balances.

Supported LND versions:

• v0.11.0-beta to v0.14.2-beta

Install

• Requires an installation of Node v12.20+

npm install -g balanceofsatoshis

Or use a platform-specific guide:

• Docker/BTCPayServer install notes
• RaspiBlitz install guide
• RaspiBolt/Debian guide
• Umbrel install guide

If you want to try out any command without npm install, you can also do npx balanceofsatoshis to run a command directly.

Get the version to verify that it's installed:

bos --version
# current installed version

Re-install if you want to update to a new version.

Usage

To see a list of available options and flags run:

bos help

# Or get individual help with a command
bos help commandName

Or ask about commands on Telegram

If you want autocomplete on commands and options you can do:

## Autocomplete on MacOS/ZSH shells (on startup: you can add this to ~/.zshrc)
autoload -Uz compinit && compinit
source <(bos completion zsh)

## Autocomplete on bash (on startup: add to ~/.profile or ~/.bash_profile)

Nodes

By default bos expects tls.cert in the root of the default lnd directory and admin.macaroon in <default_lnd_dir>/data/chain/bitcoin/<network>.

Default LND directories:

• macOS: ~/Library/Application Support/Lnd/
• Linux: ~/.lnd/

It will check first for a mainnet macaroon, then a testnet macaroon.

Saved Nodes

If you have another node and it is already using balanceofsatoshis, you can add it as a "saved node" using bos nodes --add.

Otherwise you can copy the credentials into a saved nodes directory:

To use bos with arbitrary external nodes (or nodes with custom configuration), two things need to be done:

1. Create directory ~/.bos/, and add node credentials in a format of:

   ~/.bos/YOUR_NODE_NAME/credentials.json

Use any shorthand you'd like when choosing this profile node name

2. Each file should have the following format:

    {
      "cert": "base64 tls.cert value",
      "macaroon": "base64 .macaroon value",
      "socket": "host:port"
    }

> **Note:** `cert` and (admin) `macaroon` should have base64-encoded, and newline-stripped content of the files. To get the strings in appropriate format you can run, ex:
>
>```bash
># For `cert` 
>base64 -w0 ~/.lnd/tls.cert
>
># For `macaroon`
>base64 -w0 ~/.lnd/data/chain/bitcoin/mainnet/admin.macaroon
>```
>
> **Note_2:** `socket` should contain `host:port` pointing to `lnd`'s gRPC interface, `localhost:10009` by convention.  

You can also set cert_path and macaroon_path to the path of the relevant files instead.

Umbrel Saved Node

Note: Umbrel is not FOSS software, use at your own risk.

If you are using Umbrel and you have already installed but you get an error like Name resolution failed for target dns:umbrel.local:10009 then try adding umbrel.local to your /etc/hosts file, like sudo nano /etc/hosts and add a line 127.0.0.1 umbrel.local

1. Identify your Umbrel home dir, like /home/umbrel/umbrel
2. Look in the .env file in that dir for the LND_IP to use as the socket to connect to

You can also use umbrel.local if that is in your Umbrel TLS cert but you will have to make sure the hostname is known to the client.

{
  "cert_path": "/home/umbrel/umbrel/lnd/tls.cert",
  "macaroon_path": "/home/umbrel/umbrel/lnd/data/chain/bitcoin/mainnet/admin.macaroon",
  "socket": "LND_IP:10009"
}

5. Now when you do a command, specify --node umbrel or whatever your dir is: bos --node umbrel balance

Using Saved Nodes

To run commands on nodes specified this way, you need to suffix commands with their name, ex:

bos balance --node=SAVED_NODE_NAME
bos forwards --node=SAVED_NODE_NAME

If a saved node is actually your default node, you can set an environment variable to avoid adding the --node prefix

export BOS_DEFAULT_SAVED_NODE=nodename

If that is set, it will use that node if no node is specified.

You can also add a JSON file to your .bos directory: config.json, add {"default_saved_node": "nodename"} to set the default via a file instead

Linux Fu

Some commands are designed to return outputs that can be piped or used in other CLI programs.

Open many channels

Make a textfile in the terminal with newline separated pubkeys and the capacity of the channels.

cat bos_channels.txt

       │ File: bos_channels.txt
───────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
   1   │ 0337...1986 --amount=3000000
   2   │ 02a4...20de --amount=3000000
   3   │ 023c...0dec --amount=1000000

bos open $(cat bos_channels.txt)

Summarize Numbers

expr $(bos balance --node=savedNode1) + $(bos balance --node=savedNode2)
# outputs the combined balance of both nodes

Auto Adjust Fees

# Cron every 5 minutes adjust fees
*/5 * * * * /bin/timeout -s 2 30 /home/ubuntu/update-fees.sh

update-fees.sh:

#!/bin/bash
# Raise the outbound fees to a public key when inbound increases
/home/ubuntu/.npm-global/bin/bos fees --to PUBLIC_KEY --set-fee-rate="IF(INBOUND>10000000,1000,500)"

Auto Balance Liquidity Between Two Nodes

Keep a channel balanced between two of your own nodes

# Cron: every 30 minutes send funds to reach 50:50
*/30 * * * * /home/ubuntu/.npm-global/bin/bos send PUBKEY --max-fee 0 --message="rebalance" --amount="IF(OUTBOUND+1*m>(LIQUIDITY/2), OUTBOUND-(LIQUIDITY/2), 0)"

If you want to 50:50 rebalance with a peer node, you can use --out-target-inbound=capacity/2 with bos rebalance

Alerts and Reports with sendnotification

Some commands are made with the idea that they can trigger an alert or regular report by piping the output of a command into some reporting script like sendnotification which works with AWS SNS service to deliver notifications

Examples of shell scripts that could be executed by crontab:

Cert Expiration Alert

# cert-expiration-alert.sh

#!/bin/bash
/path/to/bos cert-validity-days --below 30 | \
/path/to/sendnotification SNS "sns-topic-id" "Warning: %s days left on TLS cert" \
--nonzero --subject="Cert expiration warning"

# sends email when the certification has less than 30 days left until invalid

Daily Node Report

# daily-report.sh

#!/bin/bash
/path/to/bos report --styled 2>&1 | \
/path/to/sendnotification SNS "sns-topic-id" "%s" --subject="Daily node update"

# sends email about what has happened on the node in the past day

Low Channel Balance Alert

# low-offchain-outbound-liquidity alert

#!/bin/bash
/path/to/bos balance --offchain --below 4000000 | \
/path/to/sendnotification SNS "sns-topic-id" "off-chain balance deficit: %s sats" \
--nonzero --subject="Low balance warning"

# sends email if the channel balance goes below a threshold

Low Inbound Liquidity Alert

# low-inbound-liquidity.sh

#!/bin/bash
/path/to/bos inbound-liquidity --below=1000000 2>&1 | \
/path/to/sendnotification SNS "sns-topic-id" \
"WARNING inbound-liquidity deficit: %s sats" --nonzero \
--subject="Low inbound liquidity warning: node1"

# sends email if the inbound liquidity drops below a 1,000,000 sats

Persist Long-Running Commands

If you are running a long-running command and want it to persist, you will need something like Docker or nohup or tmux to assist you in that and then kill the process and restart it when updating.

Nohup example:

nohup /home/bos/.npm-global/bin/bos telegram --connect CONNECT_CODE > /dev/null &

Docker example:

docker run -d --restart always -v $HOME/.bos:/home/node/.bos alexbosworth/balanceofsatoshis telegram --connect CONNECT_CODE

You can also create a shell-script.sh to run a command repeatedly, with a delay

while true;
do bos rebalance;
sleep 2000;
done

Docker

This presumes you have Docker installed.

• Instructions for installing Docker on Ubuntu

Install the Docker image:

docker pull alexbosworth/balanceofsatoshis

Docker Load

You can also build the image yourself: npm run build-docker, this will make balanceofsatoshis.tar.gz that you can rsync or scp somewhere else and then do docker load < balanceofsatoshis.tar.gz.

Once the image is installed, you can "docker run" commands for all the commands:

# Make sure you have a home directory created to give Docker access to
mkdir $HOME/.bos

docker run -it --rm -v $HOME/.bos:/home/node/.bos alexbosworth/balanceofsatoshis --version
# Should output the version

This maps your home directory to the docker home directory to enable persistence of credentials.

If you want it to automatically detect your local node, also pass the LND home dir as an additional -v argument to docker run:

If you are on MacOS:

--network="host" -v $HOME/Library/Application\ Support/Lnd/:/home/node/.lnd:ro

Or on Linux:

--network="host" -v $HOME/.lnd:/home/node/.lnd:ro

On BTCPayServer:

Create the credential.json file as explained in the saved nodes section, and for socket put: "socket": "lnd_bitcoin:10009"

For Docker network use the Docker bridged network:

docker run -it --rm --network="generated_default" -v $HOME/.bos:/home/node/.bos alexbosworth/balanceofsatoshis balance --node SAVEDNODENAME

On Umbrel this would be:

# add Umbrel specific details:
## --network="host"
## --add-host=umbrel.local:192.168.1.23
## -v $HOME/umbrel/lnd:/home/node/.lnd:ro
docker run -it --rm --network="host" --add-host=umbrel.local:192.168.1.23 -v $HOME/.bos:/home/node/.bos -v $HOME/umbrel/lnd:/home/node/.lnd:ro alexbosworth/balanceofsatoshis report

Note: For umbrel-os users, when running the above docker run command, ensure the "192.168.1.23" portion of the command is updated to reflect the IP of the lnd container. You can find the IP by looking for the LND_IP value inside the $HOME/umbrel/.env file.

Otherwise you can just pass the local node credentials as shown above using the saved nodes.

If you are running a long-running command like telegram, use -d --restart always instead of -it --rm to run in daemon mode and auto-restart.

Note: if you are used to using ctrl+c to terminate the process, that doesn't work on Docker. Instead, you can use ctrl+p and then ctrl+q to background the interactive mode, then do docker ps and docker rm to kill the instance.

Build Your Own

If you don't want to use the Dockerfile, you can build a docker file for yourself

FROM node:latest
RUN npm install balanceofsatoshis
ENTRYPOINT [ "/node_modules/balanceofsatoshis/bos" ]

Run Shell Script

If you don't want to type out "docker run", and don't have an alias for it, you can create a simple shell script to fill that part in:

#! /usr/bin/env bash
docker run -it --rm -v=$HOME/.bos:/root/.bos bos:latest ${@:1}

You can also define an alias for placing in ~/.profile or ~/.bash_profile:

alias bos="docker run -it --rm -v $HOME/.bos:/home/node/.bos alexbosworth/balanceofsatoshis"

Adjust this alias to however you run the full Docker command. Remember to execute the ~/.profile to install the alias into your current session: . ~/.profile

You can also create an alias to run a command in the background

alias bosd="docker run -d --rm -v $HOME/.bos:/home/node/.bos alexbosworth/balanceofsatoshis"

Formulas

Some commands take formula arguments. Formulas are expressions that allow you to perform functions and reference variables.

There is a dynamic playground here where you can play with expressions: https://formulajs.info/functions/

--avoid

In --avoid flag commands like rebalance, a formula can be applied directionally:

--avoid "fee_rate < 100/<PUBKEY>" to avoid channels forwarding to the public key that charge a fee rate under 100 PPM.

Available variables:

• age: Age of the channel vs the current height
• base_fee: Base fee to be charged to route
• capacity: Capacity of the channel
• fee_rate: PPM fee to be charged to route
• height: Absolute height of the channel
• opposite_fee_rate: PPM fee that is charged in the non-routing direction

amount

Formula amounts are supported in the following commands:

• fund
• inbound-channel-rules
• open
• probe
• rebalance
• send

When passing an amount you can pass a formula expression, and the following variables are defined:

• k: 1,000
• m: 1,000,000

Examples:

bos fund <address> "7*m"
// Fund address with value 7,000,000

bos probe <key> "100*k"
// Probe to key amount 100,000

bos send <key> "m/2"
// Push 500,000 to key

rebalance

Rebalance defines additional variables for --amount:

• capacity: The total of inbound and outbound

And for --in-filter and --out-filter:

• capacity: The total capacity with the peer
• heights: The set of heights of the channels with the peer
• inbound_liquidity: The inbound liquidity with the peer
• outbound_liquidity: The outbound liquidity with the peer
• pending_payments: The number of pending payments

Example:

// Rebalance with a target of 1,000,000
bos rebalance --amount "1*m"

send

Send defines additional variables:

• eur: The value of 1 Euro as defined by rate provider
• inbound: The inbound liquidity with the destination
• liquidity: The total capacity with the destination
• outbound: The inbound liquidity with the destination
• usd: The value of 1 US Dollar as defined by rate provider

Example:

// Send node $1
bos send <key> --amount "1*usd"

transfer

Transfer variables:

• out_inbound: The outbound liquidity with the outbound peer
• out_liquidity: The total inbound+outbound with the outbound peer
• out_outbound: The total outbound liquidity with the outbound peer

Example:

// Equalize inbound with a mutual peer
bos transfer node "in_inbound - (in_inbound + out_inbound)/2" --through peer

fees

Variables can be referenced for --set-fee-rate

• fee_rate_of_<pubkey>: Reference other node's fee rate
• inbound: Remote balance with peer
• inbound_fee_rate: Incoming fee rate
• outbound: Local balance with peer

You can also use functions:

• bips(n): Set fee as parts per thousand
• percent(0.00): Set fee as fractional percentage

Example:

// Set the fee rate to a tag to 1% of the value forwarded
bos fees --to tag --set-fee-rate "percent(1)"

inbound-channel-rules

Pass formulas for rules with --rule.

Formula variables:

• capacities: sizes of the peer's public channels
• capacity: size of the inbound channel
• channel_ages: block ages of the peer's public channels
• fee_rates: outbound fee rates for the peer
• local_balance: gifted amount on the incoming channel
• public_key: key of the incoming peer

Example:

// Reject channels that are smaller than 2,000,000 capacity
bos inbound-channel-rules "capacity < 2*m"
