### Core Lightning configuration
### see lightningd-config(5)


## General options

# This enables developer mode, allowing developer options and commands to be
# used. It also disables deprecated APIs; use `allow-deprecated-apis=true` to
# re-enable them.
#developer

# Enable deprecated options, JSONRPC commands, fields, etc. It defaults to true
# outside developer mode, but you should set it to false when testing to ensure
# that an upgrade won't break your configuration.
#allow-deprecated-apis=BOOL

# Upgrades to Core Lightning often change the database: once this is done,
# downgrades are not generally possible. By default, Core Lightning will exit
# with an error rather than upgrade, unless this is an official released
# version. If you really want to upgrade to a non-release version, you can set
# this to true (or false to never allow a non-reversible upgrade!).
#database-upgrade=BOOL

# Deprecated features get removed slowly (over 3 releases), but sometimes
# people still get surprised when they are finally removed. As long as they
# haven't been actually fully removed, this option will re-enable it. Unless
# we've made a horrible mistake, it's probably time to complain or fix whatever
# is using the old API.  It can be specified multiple times for different
# features.
#i-promise-to-fix-broken-api-user=FEATURE


## Bitcoin control options

# Select the network parameters (bitcoin, testnet, signet, or regtest).
#network=NETWORK
network=testnet

# The name of bitcoin-cli executable to run.
#bitcoin-cli=PATH

# -datadir argument to supply to bitcoin-cli(1).
#bitcoin-datadir=DIR
bitcoin-datadir=/var/lib/bitcoind

# The RPC username for talking to bitcoind(1).
#bitcoin-rpcuser=USER

# The RPC password for talking to bitcoind(1).
#bitcoin-rpcpassword=PASSWORD

# The bitcoind(1) RPC host to connect to.
#bitcoin-rpcconnect=HOST

# The bitcoind(1) RPC port to connect to.
#bitcoin-rpcport=PORT

# The bitcoind(1) RPC client timeout in seconds. Default is set to 60 instead
# of 900 to match bitcoin-retry-timeout default. When set explicitly, the
# higher value of it and bitcoin-retry-timeout is used.
#bitcoin-rpcclienttimeout=SECONDS

# Number of seconds to keep trying a bitcoin-cli(1) command. If the command
# keeps failing after this time, exit with a fatal error.
#bitcoin-retry-timeout=SECONDS

# Number of blocks to rescan from the current head, or absolute blockheight if
# negative. This is only needed if something goes badly wrong.
#rescan=BLOCKS


## Lightning daemon options

# Sets the working directory. All files (except --conf and --lightning-dir on
# the command line) are relative to this.
#lightning-dir=DIR

# Specify pid file to write to.
#pid-file=PATH

# What log level to print out: options are io, trace, debug, info, unusual,
# broken. If SUBSYSTEM is supplied, this sets the logging level for any
# subsystem (or nodeid) containing that string. If PATH is supplied, it means
# this log-level filter is only applied to that `log-file`, which is useful for
# creating logs to capture a specific subsystem. This option may be specified
# multiple times.
#log-level=LEVEL[:SUBSYSTEM][:PATH]

# Prefix for all log lines: this can be customized if you want to merge logs
# with multiple daemons. Usually you want to include a space at the end of
# PREFIX, as the timestamp follows immediately.
#log-prefix=PREFIX

# Log to this file (instead of stdout). If you specify this more than once,
# you'll get more than one log file. - is used to mean stdout. Sending
# lightningd(8) SIGHUP will cause it to reopen each file (useful for log
# rotation).
#log-file=PATH

# Set this to false to turn off timestamp prefixes (they will still appear in
# crash log files).
#log-timestamps=BOOL

# Set JSON-RPC socket (or /dev/tty), such as for lightning-cli(1).
#rpc-file=PATH

# Set JSON-RPC socket file mode, as a 4-digit octal number. Default is 0600,
# meaning only the user that launched lightningd can command it. Set to 0660 to
# allow users with the same group to access the RPC as well.
#rpc-file-mode=MODE
rpc-file-mode=0660

# Identify the location of the wallet. This is a fully qualified data source
# name, including a scheme such as sqlite3 or postgres followed by the
# connection parameters.
#wallet=DSN

# Directory to keep the accounts.sqlite3 database file in. Defaults to
# lightning-dir.
#bookkeeper-dir=DIR

# Identify the location of the bookkeeper data. This is a fully qualified data
# source name, including a scheme such as sqlite3 or postgres followed by the
# connection parameters. Defaults to sqlite3://accounts.sqlite3 in the
# bookkeeper-dir.
#bookkeeper-db=DSN

# If set, you will be prompted to enter a password used to encrypt the
# hsm_secret. Note that once you encrypt the hsm_secret this option will be
# mandatory for lightningd to start.
#encrypted-hsm

# The port number for the GRPC plugin to listen for incoming connections;
# default is not to activate the plugin at all.
#grpc-port=PORTNUM

# The size of the buffer used by the GRPC-plugin. This buffer stores
# notifications between receiving them from lightningd and forwarding them over
# grpc. If buffer overflow occurs, some notifications will not be delivered.
#grpc-msg-buffer-size=NUMBER


## Lightning node customization options

# Restore the node from a 32-byte secret encoded as either a codex32 secret
# string or a 64-character hex string: this will fail if the hsm_secret file
# exists. Your node will start the node in offline mode, for manual recovery.
# The secret can be extracted from the hsm_secret using hsmtool(8).
#recover=HSMSECRET

# Up to 32 bytes of UTF-8 characters to tag your node. Completely silly, since
# anyone can call their node anything they want. The default is an NSA-style
# codename derived from your public key, but "Peter Todd" and "VAULTERO" are
# good options, too.
#alias=NAME

# Your favorite color as a hex code.
#rgb=RRGGBB

# The base fee to charge for every payment which passes through. Note that
# millisatoshis are a very, very small unit! Changing this value will only
# affect new channels and not existing ones. If you want to change fees for
# existing channels, use the RPC call lightning-setchannel(7).
# Default: 1000.
#fee-base=MILLISATOSHI

# This is the proportional fee to charge for every payment which passes
# through. As percentages are too coarse, it's in millionths, so 10000 is 1%,
# 1000 is 0.1%. Changing this value will only affect new channels and not
# existing ones. If you want to change fees for existing channels, use the RPC
# call lightning-setchannel(7). Default: 10 (0.001%).
#fee-per-satoshi=MILLIONTHS

# This value defines the minimal effective channel capacity in satoshi to
# accept for channel opening requests. This will reject any opening of a
# channel which can't pass an HTLC of least this value. Usually this prevents a
# peer opening a tiny channel, but it can also prevent a channel you open with
# a reasonable amount and the peer requesting such a large reserve that the
# capacity of the channel falls below this. Default: 10000.
#min-capacity-sat=SATOSHI

# Allow nodes which establish channels to us to set any fee they want. This may
# result in a channel which cannot be closed, should fees increase, but make
# channels far more reliable since we never close it due to unreasonable fees.
# Note that this can be set on a per-channel basis with lightning-
# setchannel(7).
#ignore-fee-limits=BOOL

# How long to wait before sending commitment messages to the peer: in theory
# increasing this would reduce load, but your node would have to be extremely
# busy node for you to even notice.
#commit-time=MILLISECONDS

# Networks like regtest and testnet have unreliable fee estimates: we usually
# treat them as the minimum (253 sats/kw) if we can't get them. This allows
# override of one or more of our standard feerates (see lightning-feerates(7)).
# Up to 5 values, separated by '/' can be provided: if fewer are provided, then
# the final value is used for the remainder. The values are in per-kw (roughly
# 1/4 of bitcoind's per-kb values), and the order is "opening", "mutual_close",
# "unilateral_close", "delayed_to_us", "htlc_resolution", and "penalty".
#force-feerates=VALUES

# Sets the minimal allowed HTLC value for newly created channels. If you want
# to change the `htlc_minimum_msat` for existing channels, use the RPC call
# lightning-setchannel(7). Default: 0.
#htlc-minimum-msat=MILLISATOSHI

# Sets the maximum allowed HTLC value for newly created channels. If you want
# to change the `htlc_maximum_msat` for existing channels, use the RPC call
# lightning-setchannel(7). Default: unset (no limit).
#htlc-maximum-msat=MILLISATOSHI

# Explicitly control the usage of discovered public IPs in `node_announcement`
# updates. Default: 'auto' - Only if we don't have anything else to announce.
# Note: You also need to open TCP port 9735 on your router towards your node.
# Note: Will always be disabled if you use 'always-use-proxy'.
#announce-addr-discovered=BOOL

# Sets the public TCP port to use for announcing dynamically discovered IPs.
# If unset, this defaults to the selected network's lightning port, which is
# 9735 on mainnet.
#announce-addr-discovered-port=PORT


## Lightning channel and HTLC options

# As of v23.11, this is the default (and thus, the option is ignored).
# Previously if you didn't specify this, channel sizes were limited to 16777215
# satoshi.
#large-channels

# How long we need to spot an outdated close attempt: on opening a channel we
# tell our peer that this is how long they'll have to wait if they perform a
# unilateral close.
#watchtime-blocks=BLOCKS

# The longest our funds can be delayed (ie. the longest watchtime-blocks our
# peer can ask for, and also the longest HTLC timeout we will accept). If our
# peer asks for longer, we'll refuse to create a channel, and if an HTLC asks
# for longer, we'll refuse it.
#max-locktime-blocks=BLOCKS

# Confirmations required for the funding transaction when the other side opens
# a channel before the channel is usable.
#funding-confirms=BLOCKS

# The percentage of estimatesmartfee 2/CONSERVATIVE to use for the commitment
# transactions. Default: 100.
#commit-fee=PERCENT

# The additional feerate a channel opener adds to their preferred feerate to
# lessen the odds of a disconnect due to feerate disagreement. Default: 5.
#commit-feerate-offset=INTEGER

# Number of HTLCs one channel can handle concurrently in each direction. Should
# be between 1 and 483. Default: 30.
#max-concurrent-htlcs=INTEGER

# Option which limits the total amount of sats to be allowed as dust on a
# channel.
#max-dust-htlc-exposure-msat=MILLISATOSHI

# The number of blocks between incoming payments and outgoing payments: this
# needs to be enough to make sure that if we have to, we can close the outgoing
# payment before the incoming, or redeem the incoming once the outgoing is
# redeemed.
#cltv-delta=BLOCKS

# The number of blocks to allow for payments we receive: if we have to, we
# might need to redeem this on-chain, so this is the number of blocks we have
# to do that.
#cltv-final=BLOCKS

# Normally HTLC onions which contain unknown even fields are rejected. This
# option specifies that this type is to be accepted and ignored. Can be
# specified multuple times.
#accept-htlc-tlv-type=TYPE

# This is the amount of funds to keep in the wallet to close anchor channels
# (which don't carry their own transaction fees). It defaults to 25000sat and
# is only maintained if there are any anchor channels (or when opening an
# anchor channel). This amount may be insufficient for multiple closes at once,
# however.
#min-emergency-msat=MILLISATOSHI


## Cleanup control options

# Perform search for things to clean every SECONDS seconds (default 3600, or 1
# hour, which is usually sufficient).
#autoclean-cycle=SECONDS

# How old successful forwards (`settled` in listforwards `status`) have to be
# before deletion (default 0, meaning never).
#autoclean-succeededforwards-age=SECONDS

# How old failed forwards (`failed` or `local_failed` in listforwards `status`)
# have to be before deletion (default 0, meaning never).
#autoclean-failedforwards-age=SECONDS

# How old successful payments (`complete` in listpays `status`) have to be
# before deletion (default 0, meaning never).
#autoclean-succeededpays-age=SECONDS

# How old failed payment attempts (`failed` in listpays `status`) have to be
# before deletion (default 0, meaning never).
#autoclean-failedpays-age=SECONDS

# How old invoices which were paid (`paid` in listinvoices `status`) have to be
# before deletion (default 0, meaning never).
#autoclean-paidinvoices-age=SECONDS

# How old invoices which were not paid (and cannot be) (`expired` in
# listinvoices `status`) before deletion (default 0, meaning never).
#autoclean-expiredinvoices-age=SECONDS


## Payment and invoice control options

# Disable the multi-part payment sending support in the `pay` plugin. By
# default the MPP support is enabled, but it can be desirable to disable in
# situations in which each payment should result in a single HTLC being
# forwarded in the network.
#disable-mpp

# Add a (taproot) fallback address to invoices produced by the `invoice`
# command, so that invoices can also be paid onchain.
#invoices-onchain-fallback


## Networking options

# Set an IP address (v4 or v6) or automatic Tor address to listen on and
# (maybe) announce as our node address. An empty 'IPADDRESS' is a special value
# meaning bind to IPv4 and/or IPv6 on all interfaces, '0.0.0.0' means bind to
# all IPv4 interfaces, '::' means 'bind to all IPv6 interfaces' (if you want to
# specify an IPv6 address *and* a port, use `[]` around the IPv6 address, like
# `[::]:9750`). If 'PORT' is not specified, the default port 9735 is used for
# mainnet (testnet: 19735, signet: 39735, regtest: 19846). If we can determine
# a public IP address from the resulting binding, the address is announced.
# This option can be used multiple times to add more addresses, and its use
# disables autolisten. If necessary, and 'always-use-proxy' is not specified,
# a DNS lookup may be done to resolve `HOSTNAME` or `TORIPADDRESS`.
#addr=[IPADDRESS[:PORT]]|autotor:TORIPADDRESS[:SERVICEPORT][/torport=TORPORT]|statictor:TORIPADDRESS[:SERVICEPORT][/torport=TORPORT][/torblob=[blob]]|HOSTNAME[:PORT]

# Set an IP address or UNIX domain socket to listen to, but do not announce. A
# UNIX domain socket is distinguished from an IP address by beginning with a /.
# An empty 'IPADDRESS' is a special value meaning bind to IPv4 and/or IPv6 on
# all interfaces, '0.0.0.0' means bind to all IPv4 interfaces, '::' means 'bind
# to all IPv6 interfaces'. If 'PORT' is not specified, 9735 is used. This
# option can be used multiple times to add more addresses, and its use disables
# autolisten. If necessary, and 'always-use-proxy' is not specified, a DNS
# lookup may be done to resolve 'HOSTNAME'.
#bind-addr=[IPADDRESS[:PORT]]|SOCKETPATH|HOSTNAME[:PORT]

# Set an IP (v4 or v6) address or Tor address to announce; a Tor address is
# distinguished by ending in .onion. PORT defaults to 9735. Empty or wildcard
# IPv4 and IPv6 addresses don't make sense here. Also, unlike the 'addr'
# option, there is no checking that your announced addresses are public (e.g.,
# not localhost). This option can be used multiple times to add more addresses,
# and its use disables autolisten. The `dns:` prefix can be used to indicate
# that this hostname and port should be announced as a DNS hostname entry.
# Please note that most mainnet nodes do not yet use, read, or propagate this
# information correctly.
#announce-addr=IPADDRESS[:PORT]|TORADDRESS.onion[:PORT]|dns:HOSTNAME[:PORT]

# Do not bind to any ports, and do not try to reconnect to any peers. This can
# be useful for maintenance and forensics, so is usually specified on the
# command line. Overrides all addr and bind-addr options.
#offline

# By default, we bind (and maybe announce) on IPv4 and IPv6 interfaces if no
# addr, bind-addr or announce-addr options are specified. Setting this to false
# disables that.
#autolisten=BOOL

# Set a socks proxy to use to connect to Tor nodes (or for all connections if
# always-use-proxy is set). The port defaults to 9050 if not specified.
#proxy=IPADDRESS[:PORT]

# Always use the proxy, even to connect to normal IP addresses (you can still
# connect to Unix domain sockets manually). This also disables all DNS lookups,
# to avoid leaking information.
#always-use-proxy=BOOL

# Disable the DNS bootstrapping mechanism to find a node by its node ID.
#disable-dns

# Set a Tor control password, which may be needed for autotor: to authenticate
# to the Tor control port.
#tor-service-password=PASSWORD


## Lightning plugins

# Specify a plugin to run as part of Core Lightning. This can be specified
# multiple times to add multiple plugins. Note that unless plugins themselves
# specify ordering requirements for being called on various hooks, plugins will
# be ordered by command line, then config file.
#plugin=PATH

# Specify a directory to look for plugins; all executable files not containing
# punctuation (other than ., - or _) in DIRECTORY are loaded. DIRECTORY must
# exist; this can be specified multiple times to add multiple directories. The
# ordering of plugins within a directory is currently unspecified.
#plugin-dir=DIRECTORY

# This option clears all plugin, important-plugin, and plugin-dir options
# preceding it, including the default built-in plugin directory. You can still
# add plugin-dir, plugin, and important-plugin options following this and they
# will have the normal effect.
#clear-plugins

# If PLUGIN contains a /, plugins with the same path as PLUGIN will not be
# loaded at startup. Otherwise, no plugin with that base name will be loaded at
# startup, whatever directory it is in. This option is useful for disabling a
# single plugin inside a directory. You can still explicitly load plugins which
# have been disabled, using lightning-plugin(7) start.
#disable-plugin=PLUGIN

# Specify a plugin to run as part of Core Lightning. This can be specified
# multiple times to add multiple plugins. Plugins specified via this option are
# considered so important, that if the plugin stops for any reason (including
# via lightning-plugin(7) stop), Core Lightning will also stop running. This
# way, you can monitor crashes of important plugins by simply monitoring if
# Core Lightning terminates. Built-in plugins, which are installed with
# lightningd(8), are automatically considered important.
#important-plugin=PLUGIN
