LND gRPC API Reference
Welcome to the gRPC API reference documentation for LND, the Lightning Network
Daemon.
This site features the API documentation for lncli (CLI), Python,
and JavaScript in
order to communicate with a local lnd instance through gRPC. It is intended
for those who already understand how to work with LND. If this is your first
time or you need a refresher, you may consider perusing our LND developer site
featuring a tutorial, resources and guides at dev.lightning.community.
The examples to the right assume that the there is a local lnd instance
running and listening for gRPC connections on port 10009. LND_DIR will be used
as a placeholder to denote the base directory of the lnd instance. By default,
this is ~/.lnd on Linux and ~/Library/Application Support/Lnd on macOS.
At the time of writing this documentation, two things are needed in order to
make a gRPC request to an lnd instance: a TLS/SSL connection and a macaroon
used for RPC authentication. The examples to the right will show how these can
be used in order to make a successful, secure, and authenticated gRPC request.
The original *.proto files from which the gRPC documentation was generated
can be found here:
This is the reference for the gRPC API. Alternatively, there is also a REST
API which is documented here.
This documentation was
generated automatically against commit
17014b592e0fb0acb4b1ac6db9e298b8f9acc4f1.
Experimental services
The following RPCs/services are currently considered to be experimental. This means
they are subject to change in the future. They also need to be enabled with a
compile-time flag to be active (they are active in the official release binaries).
Service Autopilot
ModifyStatus
Unary RPC
ModifyStatus is used to modify the status of the autopilot agent, like enabling or disabling it.

Service ChainNotifier
RegisterBlockEpochNtfn
Server-streaming RPC
RegisterBlockEpochNtfn is a synchronous response-streaming RPC that registers an intent for a client to be notified of blocks in the chain. The stream will return a hash and height tuple of a block for each new/stale block in the chain. It is the client's responsibility to determine whether the tuple returned is for a new or stale block in the chain. A client can also request a historical backlog of blocks from a particular point. This allows clients to be idempotent by ensuring that they do not missing processing a single block within the chain.

RegisterConfirmationsNtfn
Server-streaming RPC
RegisterConfirmationsNtfn is a synchronous response-streaming RPC that registers an intent for a client to be notified once a confirmation request has reached its required number of confirmations on-chain. A confirmation request must have a valid output script. It is also possible to give a transaction ID. If the transaction ID is not set, a notification is sent once the output script confirms. If the transaction ID is also set, a notification is sent once the output script confirms in the given transaction.

uint32 |
The number of desired confirmations the transaction/output script should reach before dispatching a confirmation notification. |
| height_hint |
uint32 |
The earliest height in the chain for which the transaction/output script could have been included in a block. This should in most cases be set to the broadcast height of the transaction/output script. |
| include_block |
bool |

| Parameter |
Type |
Description |
| conf |
ConfDetails |
An event that includes the confirmation details of the request (txid/ouput script). |
| reorg |
Reorg |
An event send when the transaction of the request is reorged out of the chain. |
RegisterSpendNtfn

RegisterSpendNtfn is a synchronous response-streaming RPC that registers an intent for a client to be notification once a spend request has been spent by a transaction that has confirmed on-chain. A client can specify whether the spend request should be for a particular outpoint or for an output script by specifying a zero outpoint.

| Parameter |
Type |
Description |
| outpoint |
Outpoint |
The outpoint for which we should request a spend notification for. If set to a zero outpoint, then the spend notification will be requested for the script instead. A zero or nil outpoint is not supported for Taproot spends because the output script cannot reliably be computed from the witness alone and the spent output script is not always available in the rescan context. So an outpoint must always be specified when registering a spend notification for a Taproot output. |
| script |
bytes |
The output script for the outpoint above. This will be used by light clients to match block filters. If the outpoint is set to a zero outpoint, then a spend notification will be requested for this script instead. |
| height_hint |
uint32 |
The earliest height in the chain for which the outpoint/output script could have been spent. This should in most cases be set to the broadcast height of the outpoint/output script. |
| Parameter |
Type |
Description |
| spend |
SpendDetails |
An event that includes the details of the spending transaction of the request (outpoint/output script). |
| reorg |
Reorg |
An event sent when the spending transaction of the request was reorged out of the chain. |

AbandonChannel
Unary RPC
AbandonChannel removes all channel state from the database except for a close summary. This method can be used to get rid of permanently unusable channels due to bugs fixed in newer versions of lnd. This method can also be used to remove externally funded channels where the funding transaction was never broadcast. Only available for non-externally funded channels in dev build.
# Removes all channel state from the database except for a close
# summary. This method can be used to get rid of permanently unusable
# channels due to bugs fixed in newer versions of lnd.
# Only available when lnd is built in debug mode. The flag
# --i_know_what_i_am_doing can be set to override the debug/dev mode
# requirement.
# To view which funding_txids/output_indexes can be used for this command,
# see the channel_point values within the listchannels command output.
# The format for a channel_point is 'funding_txid:output_index'.
$ lncli abandonchannel [command options] funding_txid [output_index]
# --funding_txid value the txid of the channel's funding transaction
# --output_index value the output index for the funding output of the funding transaction (default: 0)
# --chan_point value (optional) the channel point. If set, funding_txid and output_index flags and positional arguments will be ignored
# --i_know_what_i_am_doing override the requirement for lnd needing to be in dev/debug mode to use this command; when setting this the user attests that they know the danger of using this command on channels and that doing so can lead to loss of funds if the channel funding TX ever confirms (or was confirmed)

AddInvoice
Unary RPC
AddInvoice attempts to add a new invoice to the invoice database. Any duplicated invoices are rejected, therefore all invoices must have a unique payment preimage.
# Add a new invoice, expressing intent for a future payment.
# Invoices without an amount can be created by not supplying any
# parameters or providing an amount of 0. These invoices allow the payee
# to specify the amount of satoshis they wish to send.
$ lncli addinvoice [command options] value preimage
# --memo value a description of the payment to attach along with the invoice (default="")
# --preimage value the hex-encoded preimage (32 byte) which will allow settling an incoming HTLC payable to this preimage. If not set, a random preimage will be created.
# --amt value the amt of satoshis in this invoice (default: 0)
# --amt_msat value the amt of millisatoshis in this invoice (default: 0)
# --description_hash value SHA-256 hash of the description of the payment. Used if the purpose of payment cannot naturally fit within the memo. If provided this will be used instead of the description(memo) field in the encoded invoice.
# --fallback_addr value fallback on-chain address that can be used in case the lightning payment fails
# --expiry value the invoice's expiry time in seconds. If not specified an expiry of 3600 seconds (1 hour) is implied. (default: 0)
# --private encode routing hints in the invoice with private channels in order to assist the payer in reaching you
# --amp creates an AMP invoice. If true, preimage should not be set.

BakeMacaroon
Unary RPC
BakeMacaroon allows the creation of a new macaroon with custom read and write permissions. No first-party caveats are added since this can be done offline.
# Bake a new macaroon that grants the provided permissions and
# optionally adds restrictions (timeout, IP address) to it.
# The new macaroon can either be shown on command line in hex serialized
# format or it can be saved directly to a file using the --save_to
# argument.
# A permission is a tuple of an entity and an action, separated by a
# colon. Multiple operations can be added as arguments, for example:
# lncli bakemacaroon info:read invoices:write foo:bar
# For even more fine-grained permission control, it is also possible to
# specify single RPC method URIs that are allowed to be accessed by a
# macaroon. This can be achieved by specifying "uri:<methodURI>" pairs,
# for example:
# lncli bakemacaroon uri:/lnrpc.Lightning/GetInfo uri:/verrpc.Versioner/GetVersion
# The macaroon created by this command would only be allowed to use the
# "lncli getinfo" and "lncli version" commands.
# To get a list of all available URIs and permissions, use the
# "lncli listpermissions" command.
$ lncli bakemacaroon [command options] [--save_to=] [--timeout=] [--ip_address=] [--custom_caveat_name= [--custom_caveat_condition=]] [--root_key_id=] [--allow_external_permissions] permissions...
# --save_to value save the created macaroon to this file using the default binary format
# --timeout value the number of seconds the macaroon will be valid before it times out (default: 0)
# --ip_address value the IP address the macaroon will be bound to
# --custom_caveat_name value the name of the custom caveat to add
# --custom_caveat_condition value the condition of the custom caveat to add, can be empty if custom caveat doesn't need a value
# --root_key_id value the numerical root key ID used to create the macaroon (default: 0)

BatchOpenChannel
Unary RPC
BatchOpenChannel attempts to open multiple single-funded channels in a single transaction in an atomic way. This means either all channel open requests succeed at once or all attempts are aborted if any of them fail. This is the safer variant of using PSBTs to manually fund a batch of channels through the OpenChannel RPC.
# Attempt to open one or more new channels to an existing peer with the
# given node-keys.
# Example:
# lncli batchopenchannel --sat_per_vbyte=5 '[{
# "node_pubkey": "02abcdef...",
# "local_funding_amount": 500000,
# "private": true,
# "close_address": "bc1qxxx..."
# }, {
# "node_pubkey": "03fedcba...",
# "local_funding_amount": 200000,
# "remote_csv_delay": 288
# }]'
# All nodes listed must already be connected peers, otherwise funding will
# fail.
# The channel will be initialized with local_funding_amount satoshis
# locally and push_sat satoshis for the remote node. Note that specifying
# push_sat means you give that amount to the remote node as part of the
# channel opening. Once the channel is open, a channelPoint (txid:vout) of
# the funding output is returned.
# If the remote peer supports the option upfront shutdown feature bit
# (query listpeers to see their supported feature bits), an address to
# enforce payout of funds on cooperative close can optionally be provided.
# Note that if you set this value, you will not be able to cooperatively
# close out to another address.
# One can manually set the fee to be used for the funding transaction via
# either the --conf_target or --sat_per_vbyte arguments. This is optional.
$ lncli batchopenchannel [command options] channels-json
# --conf_target value (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_vbyte value (optional) a manual fee expressed in sat/vByte that should be used when crafting the transaction (default: 0)
# --min_confs value (optional) the minimum number of confirmations each one of your outputs used for the funding transaction must satisfy (default: 1)
# --label value (optional) a label to attach to the batch transaction when storing it to the local wallet after publishing it

ChannelAcceptor
Bidirectional-streaming RPC
ChannelAcceptor dispatches a bi-directional streaming RPC in which OpenChannel requests are sent to the client and the client responds with a boolean that tells LND whether or not to accept the channel. This allows node operators to specify their own criteria for accepting inbound channels through a single persistent connection.

Description |
| accept |
bool |
Whether or not the client accepts the channel. |
| pending_chan_id |
bytes |
The pending channel id to which this response applies. |
| error |
string |
An optional error to send the initiating party to indicate why the channel was rejected. This field should not contain sensitive information, it will be sent to the initiating party. This field should only be set if accept is false, the channel will be rejected if an error is set with accept=true because the meaning of this response is ambiguous. Limited to 500 characters. |
| upfront_shutdown |
string |
The upfront shutdown address to use if the initiating peer supports option upfront shutdown script (see ListPeers for the features supported). Note that the channel open will fail if this value is set for a peer that does not support this feature bit. |
| csv_delay |
uint32 |
The csv delay (in blocks) that we require for the remote party. |
| reserve_sat |
uint64 |
The reserve amount in satoshis that we require the remote peer to adhere to. We require that the remote peer always have some reserve amount allocated to them so that there is always a disincentive to broadcast old state (if they hold 0 sats on their side of the channel, there is nothing to lose). |
| in_flight_max_msat |
uint64 |
The maximum amount of funds in millisatoshis that we allow the remote peer to have in outstanding htlcs. |

uint64 |
The minimum value in millisatoshis for incoming htlcs on the channel. |
| min_accept_depth |
uint32 |
The number of confirmations we require before we consider the channel open. |
| zero_conf |
bool |
Whether the responder wants this to be a zero-conf channel. This will fail if either side does not have the scid-alias feature bit set. The minimum depth field must be zero if this is true. |
| Parameter |
Type |
Description |
| node_pubkey |
bytes |
The pubkey of the node that wishes to open an inbound channel. |

The minimum amount of satoshis the initiator requires us to have at all times. |
| min_htlc |
uint64 |
The smallest HTLC in millisatoshis that the initiator will accept. |
| fee_per_kw |
uint64 |
The initial fee rate that the initiator suggests for both commitment transactions. |
| csv_delay |
uint32 |
The number of blocks to use for the relative time lock in the pay-to-self output of both commitment transactions. |
| max_accepted_htlcs |
uint32 |
The total number of incoming HTLC's that the initiator will accept. |

CloseChannel
Server-streaming RPC
CloseChannel attempts to close an active channel identified by its channel outpoint (ChannelPoint). The actions of this method can additionally be augmented to attempt a force close after a timeout period in the case of an inactive peer. If a non-force close (cooperative closure) is requested, then the user can specify either a target number of blocks until the closure transaction is confirmed, or a manual fee rate. If neither are specified, then a default lax, block confirmation target is used.
# Close an existing channel. The channel can be closed either cooperatively,
# or unilaterally (--force).
# A unilateral channel closure means that the latest commitment
# transaction will be broadcast to the network. As a result, any settled
# funds will be time locked for a few blocks before they can be spent.
# In the case of a cooperative closure, one can manually set the fee to
# be used for the closing transaction via either the --conf_target or
# --sat_per_vbyte arguments. This will be the starting value used during
# fee negotiation. This is optional.
# In the case of a cooperative closure, one can manually set the address
# to deliver funds to upon closure. This is optional, and may only be used
# if an upfront shutdown address has not already been set. If neither are
# set the funds will be delivered to a new wallet address.
# To view which funding_txids/output_indexes can be used for a channel close,
# see the channel_point values within the listchannels command output.
# The format for a channel_point is 'funding_txid:output_index'.
$ lncli closechannel [command options] funding_txid [output_index]
# --funding_txid value the txid of the channel's funding transaction
# --output_index value the output index for the funding output of the funding transaction (default: 0)
# --chan_point value (optional) the channel point. If set, funding_txid and output_index flags and positional arguments will be ignored
# --force attempt an uncooperative closure
# --block block until the channel is closed
# --conf_target value (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation. If not set, then the conf-target value set in the main lnd config will be used. (default: 0)
# --sat_per_vbyte value (optional) a manual fee expressed in sat/vbyte that should be used when crafting the transaction (default: 0)
# --delivery_addr value (optional) an address to deliver funds upon cooperative channel closing, may only be used if an upfront shutdown address is not already set

The target number of blocks that the closure transaction should be confirmed by. |
| sat_per_byte |
int64 |
Deprecated, use sat_per_vbyte. A manual fee rate set in sat/vbyte that should be used when crafting the closure transaction. |
| delivery_address |
string |
An optional address to send funds to in the case of a cooperative close. If the channel was opened with an upfront shutdown script and this field is set, the request to close will fail because the channel must pay out to the upfront shutdown addresss. |
| sat_per_vbyte |
uint64 |
A manual fee rate set in sat/vbyte that should be used when crafting the closure transaction. |

ConnectPeer
Unary RPC
ConnectPeer attempts to establish a connection to a remote peer. This is at the networking level, and is used for communication between nodes. This is distinct from establishing a channel with a peer.
# Connect to a peer using its <pubkey> and host.
# A custom timeout on the connection is supported. For instance, to timeout
# the connection request in 30 seconds, use the following:
# lncli connect <pubkey>@host --timeout 30s
$ lncli connect [command options] <pubkey>@host
# --perm If set, the daemon will attempt to persistently connect to the target peer.
# If not, the call will be synchronous.
# --timeout value The connection timeout value for current request. Valid uints are {ms, s, m, h}.
# If not set, the global connection timeout value (default to 120s) is used. (default: 0s)

DebugLevel
Unary RPC
DebugLevel allows a caller to programmatically set the logging verbosity of lnd. The logging can be targeted according to a coarse daemon-wide logging level, or in a granular fashion to specify the logging for a target sub-system.
# Logging level for all subsystems {trace, debug, info, warn, error, critical, off}

# Use show to list available subsystems
$ lncli debuglevel [command options] [arguments...]
# --show if true, then the list of available sub-systems will be printed out

DescribeGraph
Unary RPC
DescribeGraph returns a description of the latest graph state from the point of view of the node. The graph information is partitioned into two components: all the nodes/vertexes, and all the edges that connect the vertexes themselves. As this is a directed graph, the edges also contain the node directional specific routing policy which includes: the time lock delta, fee information, etc.
# Prints a human readable version of the known channel graph from the PoV of the node

EstimateFee
Unary RPC
EstimateFee asks the chain backend to estimate the fee rate and total fees for a transaction that pays to multiple specified outputs. When using REST, the AddrToAmount map type can be set by appending &AddrToAmount[<address>]=<amount_to_send> to the URL. Unfortunately this map type doesn't appear in the REST API documentation because of a bug in the grpc-gateway library.
# Get fee estimates for sending a transaction paying the specified amount(s) to the passed address(es).
# The send-json-string' param decodes addresses and the amount to send respectively in the following format:
# '{"ExampleAddr": NumCoinsInSatoshis, "SecondAddr": NumCoins}'

# a selected channel. SCB's are encrypted backups of a channel's initial
# state that are encrypted with a key derived from the seed of a user. In
# the case of partial or complete data loss, the SCB will allow the user
# to reclaim settled funds in the channel at its final state. The
# exported channel backups can be restored at a later time using the
# restorechanbackup command.
# This command will return one of two types of channel backups depending
# on the set of passed arguments:
# * If a target channel point is specified, then a single channel
# backup containing only the information for that channel will be
# returned.
# * If the --all flag is passed, then a multi-channel backup will be
# returned. A multi backup is a single encrypted blob (displayed in
# hex encoding) that contains several channels in a single cipher
# text.
# Both of the backup types can be restored using the restorechanbackup
# command.
$ lncli exportchanbackup [command options] [chan_point] [--all] [--output_file]
# --chan_point value the target channel to obtain an SCB for
# --all if specified, then a multi backup of all active channels will be returned
# --output_file value if specified, then rather than printing a JSON output
# of the static channel backup, a serialized version of
# the backup (either Single or Multi) will be written to
# the target file, this is the same format used by lnd in
# its channel.backup file

ForwardingHistory
Unary RPC
ForwardingHistory allows the caller to query the htlcswitch for a record of all HTLCs forwarded within the target time range, and integer offset within that time range, for a maximum number of events. If no maximum number of events is specified, up to 100 events will be returned. If no time-range is specified, then events will be returned in the order that they occured. A list of forwarding events are returned. The size of each forwarding event is 40 bytes, and the max message size able to be returned in gRPC is 4 MiB. As a result each message can only contain 50k entries. Each response has the index offset of the last entry. The index offset can be provided to the request to allow the caller to skip a series of records.
# Query the HTLC switch's internal forwarding log for all completed
# payment circuits (HTLCs) over a particular time range (--start_time and
# --end_time). The start and end times are meant to be expressed in
# seconds since the Unix epoch.
# Alternatively negative time ranges can be used, e.g. "-3d". Supports
# s(seconds), m(minutes), h(ours), d(ays), w(eeks), M(onths), y(ears).
# Month equals 30.44 days, year equals 365.25 days.
# If --start_time isn't provided, then 24 hours ago is used. If
# --end_time isn't provided, then the current time is used.
# The max number of events returned is 50k. The default number is 100,
# callers can use the --max_events param to modify this value.
# Finally, callers can skip a series of events using the --index_offset
# parameter. Each response will contain the offset index of the last
# entry. Using this callers can manually paginate within a time slice.
$ lncli fwdinghistory [command options] start_time [end_time] [index_offset] [max_events]
# --start_time value the starting time for the query as unix timestamp or relative e.g. "-1w"
# --end_time value the end time for the query as unix timestamp or relative e.g. "-1w"

End time is the end point of the forwarding history request. The response will carry at most 50k records between the start time and the end time. The index offset can be used to implement pagination. |
| index_offset |
uint32 |
Index offset is the offset in the time series to start at. As each response can only contain 50k records, callers can use this to skip around within a packed time series. |
| num_max_events |
uint32 |
The max number of events to return in the response to this query. |
| Parameter |
Type |
Description |
| forwarding_events |
array ForwardingEvent |
A list of forwarding events from the time slice of the time series specified in the request. |
| last_offset_index |
uint32 |
The index of the last time in the set of returned forwarding events. Can be used to seek further, pagination style. |
FundingStateStep
Unary RPC
FundingStateStep is an advanced funding related call that allows the caller to either execute some preparatory steps for a funding workflow, or manually progress a funding workflow. The primary way a funding flow is identified is via its pending channel ID. As an example, this method can be used to specify that we're expecting a funding flow for a particular pending channel ID, for which we need to use specific parameters. Alternatively, this can be used to interactively drive PSBT signing for funding for partially complete funding transactions.

# Pagination is supported by the usage of index_offset in combination with
# the paginate_forwards flag.
# Reversed pagination is enabled by default to receive current payments
# first. Pagination can be resumed by using the returned last_index_offset
# (for forwards order), or first_index_offset (for reversed order) as the
# offset_index.
# Because counting all payments in the payment database can take a long
# time on systems with many payments, the count is not returned by
# default. That feature can be turned on with the --count_total_payments
# flag.
$ lncli listpayments [command options] [arguments...]
# --include_incomplete if set to true, payments still in flight (or failed) will be returned as well, keepingindices for payments the same as without the flag
# --index_offset value The index of a payment that will be used as either the start (in forwards mode) or end (in reverse mode) of a query to determine which payments should be returned in the response, where the index_offset is excluded. If index_offset is set to zero in reversed mode, the query will end with the last payment made. (default: 0)
# --max_payments value the max number of payments to return, by default, all completed payments are returned (default: 0)
# --paginate_forwards if set, payments succeeding the index_offset will be returned, allowing forwards pagination
# --count_total_payments if set, all payments (complete or incomplete, independent of max_payments parameter) will be counted; can take a long time on systems with many payments

| Parameter |
Type |
Description |
| include_incomplete |
bool |
If true, then return payments that have not yet fully completed. This means that pending payments, as well as failed payments will show up if this field is set to true. This flag doesn't change the meaning of the indices, which are tied to individual payments. |
| index_offset |
uint64 |
The index of a payment that will be used as either the start or end of a query to determine which payments should be returned in the response. The index_offset is exclusive. In the case of a zero index_offset, the query will start with the oldest payment when paginating forwards, or will end with the most recent payment when paginating backwards. |
| max_payments |
uint64 |
The maximal number of payments returned in the response to this query. |
| reversed |
bool |
If set, the payments returned will result from seeking backwards from the specified index offset. This can be used to paginate backwards. The order of the returned payments is always oldest first (ascending index order). |
| count_total_payments |
bool |
If set, all payments (complete and incomplete, independent of the max_payments parameter) will be counted. Note that setting this to true will increase the run time of the call significantly on systems that have a lot of payments, as all of them have to be iterated through to be counted. |
| Parameter |
Type |
Description |
| payments |
array Payment |
The list of payments |
| first_index_offset |
uint64 |
The index of the first item in the set of returned payments. This can be used as the index_offset to continue seeking backwards in the next request. |
| last_index_offset |
uint64 |
The index of the last item in the set of returned payments. This can be used as the index_offset to continue seeking forwards in the next request. |
| total_num_payments |
uint64 |
Will only be set if count_total_payments in the request was set. Represents the total number of payments (complete and incomplete, independent of the number of payments requested in the query) currently present in the payments database. |

| Parameter |
Type |
Description |
| r_hash_str |
string |
The hex-encoded payment hash of the invoice to be looked up. The passed payment hash must be exactly 32 bytes, otherwise an error is returned. Deprecated now that the REST gateway supports base64 encoding of bytes fields. |
| r_hash |
bytes |
The payment hash of the invoice to be looked up. When using REST, this field must be encoded as base64. |
| Parameter |
Type |
Description |
| memo |
string |

Whether this invoice should include routing hints for private channels. |
| add_index |
uint64 |
The "add" index of this invoice. Each newly created invoice will increment this index making it monotonically increasing.

| amt_paid_msat |
int64 |
The amount that was accepted for this invoice, in millisatoshis. This will ONLY be set if this invoice has been settled. We provide this field as if the invoice was created with a zero value, then we need to record what amount was ultimately accepted.

| payment_addr |
bytes |
The payment address of this invoice. This value will be used in MPP payments, and also for newer invoices that always require the MPP payload for added end-to-end security. Note: Output only, don't specify for creating an invoice. |
| is_amp |
bool |
Signals whether or not this is an AMP invoice. |
| amp_invoice_state |
array AmpInvoiceStateEntry |
[EXPERIMENTAL]: Maps a 32-byte hex-encoded set ID to the sub-invoice AMP state for the given set ID.

OpenChannel
Server-streaming RPC
OpenChannel attempts to open a singly funded channel specified in the request to a remote peer. Users are able to specify a target number of blocks that the funding transaction should be confirmed in, or a manual fee rate to us for the funding transaction. If neither are specified, then a lax block confirmation target is used. Each OpenStatusUpdate will return the pending channel ID of the in-progress channel. Depending on the arguments specified in the OpenChannelRequest, this pending channel ID can then be used to manually progress the channel funding flow.
# Attempt to open a new channel to an existing peer with the key node-key
# optionally blocking until the channel is 'open'.
# One can also connect to a node before opening a new channel to it by
# setting its host:port via the --connect argument. For this to work,
# the node_key must be provided, rather than the peer_id. This is optional.
# The channel will be initialized with local-amt satoshis local and push-amt
# satoshis for the remote node. Note that specifying push-amt means you give that
# amount to the remote node as part of the channel opening. Once the channel is open,
# a channelPoint (txid:vout) of the funding output is returned.
# If the remote peer supports the option upfront shutdown feature bit (query
# listpeers to see their supported feature bits), an address to enforce
# payout of funds on cooperative close can optionally be provided. Note that
# if you set this value, you will not be able to cooperatively close out to
# another address.
# One can manually set the fee to be used for the funding transaction via either
# the --conf_target or --sat_per_vbyte arguments. This is optional.
$ lncli openchannel [command options] node-key local-amt push-amt
# --node_key value the identity public key of the target node/peer serialized in compressed format
# --connect value (optional) the host:port of the target node
# --local_amt value the number of satoshis the wallet should commit to the channel (default: 0)
# --push_amt value the number of satoshis to give the remote side as part of the initial commitment state, this is equivalent to first opening a channel and sending the remote party funds, but done all in one step (default: 0)
# --block block and wait until the channel is fully open
# --conf_target value (optional) the number of blocks that the transaction *should* confirm in, will be used for fee estimation (default: 0)
# --sat_per_vbyte value (optional) a manual fee expressed in sat/vbyte that should be used when crafting the transaction (default: 0)
# --private make the channel private, such that it won't be announced to the greater network, and nodes other than the two channel endpoints must be explicitly told about it to be able to route through it
# --min_htlc_msat value (optional) the minimum value we will require for incoming HTLCs on the channel (default: 0)
# --remote_csv_delay value (optional) the number of blocks we will require our channel counterparty to wait before accessing its funds in case of unilateral close. If this is not set, we will scale the value according to the channel size (default: 0)
# --max_local_csv value (optional) the maximum number of blocks that we will allow the remote peer to require we wait before accessing our funds in the case of a unilateral close. (default: 0)
# --min_confs value (optional) the minimum number of confirmations each one of your outputs used for the funding transaction must satisfy (default: 1)
# --close_address value (optional) an address to enforce payout of our funds to on cooperative close. Note that if this value is set on channel open, you will *not* be able to cooperatively close to a different address.
# --psbt start an interactive mode that initiates funding through a partially signed bitcoin transaction (PSBT), allowing the channel funds to be added and signed from a hardware or other offline device.
# --base_psbt value when using the interactive PSBT mode to open a new channel, use this base64 encoded PSBT as a base and add the new channel output to it instead of creating a new, empty one.
# --no_publish when using the interactive PSBT mode to open multiple channels in a batch, this flag instructs lnd to not publish the full batch transaction just yet. For safety reasons this flag should be set for each of the batch's transactions except the very last
# --remote_max_value_in_flight_msat value (optional) the maximum value in msat that can be pending within the channel at any given time (default: 0)
# --channel_type value (optional) the type of channel to propose to the remote peer ("tweakless", "anchors")
# --zero_conf (optional) whether a zero-conf channel open should be attempted.
# --scid_alias (optional) whether a scid-alias channel type should be negotiated.

QueryRoutes
Unary RPC
QueryRoutes attempts to query the daemon's Channel Router for a possible route to a target destination capable of carrying a specific amount of satoshis. The returned route contains the full details required to craft and send an HTLC, also including the necessary information that should be present within the Sphinx packet encapsulated within the HTLC. When using REST, the dest_custom_records map type can be set by appending &dest_custom_records[<record_number>]=<record_data_base64_url_encoded> to the URL. Unfortunately this map type doesn't appear in the REST API documentation because of a bug in the grpc-gateway library.
# Queries the channel router for a potential path to the destination that has sufficient flow for the amount including fees
$ lncli queryroutes [command options] dest amt
# --dest value the 33-byte hex-encoded public key for the payment destination
