|
|
|
This lnrpc package implements both a client and server for `lnd`s RPC system
|
|
which is based off of the high-performance cross-platform
|
|
[gRPC](http://www.grpc.io/) RPC framework. By default, only the Go
|
|
client+server libraries are compiled within the package. In order to compile
|
|
the client side libraries for other supported languages, the `protoc` tool will
|
|
need to be used to generate the compiled protos for a specific language.
|
|
|
|
The following languages are supported as clients to `lnrpc`: C++, Go, Node.js,
|
|
Java, Ruby, Android Java, PHP, Python, C#, Objective-C.
|
|
|
|
The list of defined RPC's on the main service are the following (with a brief

|
|
* Returns a list of on-chain transactions that pay to or are spends from

* SubscribeTransactions
|
|
* Returns a stream which sends async notifications each time a transaction
|
|
is created or one is received that pays to us.
|
|
* SendMany
|
|
* Allows the caller to create a transaction with an arbitrary fan-out

|
(many outputs).
|
|
* NewAddress

|
* Returns a new address, the following address types are supported:
|
|
pay-to-public-key-hash (p2pkh), pay-to-witness-key-hash (p2wkh), and
|
|
nested-pay-to-witness-key-hash (np2wkh).
|
|
* SignMessage
|
|
* Signs a message with the node's identity key and returns a
|
|
zbase32 encoded signature.
|
|
* VerifyMessage
|
|
* Verifies a signature signed by another node on a message. The other node
|
|
must be an active node in the channel database.
|
|
* ConnectPeer
|
|
* Connects to a peer identified by a public key and host.
|
|
* DisconnectPeer
|
|
* Disconnects a peer identified by a public key.

|
|
* ListChannels

|
|
* Send a payment over Lightning to a target peer.

* ListPayments
|
|
* List all outgoing Lightning payments the daemon has made.
|
|
* DescribeGraph
|
|
* Returns a description of the known channel graph from the PoV of the
