lnrpc

Build Status MIT licensed GoDoc

This lnrpc package implements both a client and server for lnds RPC system which is based off of the high-performance cross-platform gRPC 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 description):

  • WalletBalance
    • Returns the wallet's current confirmed balance in BTC.
  • ChannelBalance
    • Returns the daemons' available aggregate channel balance in BTC.
  • GetTransactions
    • Returns a list of on-chain transactions that pay to or are spends from lnd.
  • SendCoins
    • Sends an amount of satoshis to a specific address.
  • 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.
  • ListPeers
    • Lists all available connected peers.
  • GetInfo
    • Returns basic data concerning the daemon.
  • PendingChannels
    • List the number of pending (not fully confirmed) channels.
  • ListChannels
    • List all active channels the daemon manages.
  • OpenChannel
    • Attempts to open a channel to a target peer with a specific amount and push amount.
  • CloseChannel
    • Attempts to close a target channel. A channel can either be closed cooperatively if the channel peer is online, or using a "force" close to broadcast the latest channel state.
  • SendPayment
    • Send a payment over Lightning to a target peer.
  • AddInvoice
    • Adds an invoice to the daemon. Invoices are automatically settled once seen as an incoming HTLC.
  • ListInvoices
    • Lists all stored invoices.
  • LookupInvoice
    • Attempts to look up an invoice by payment hash (r-hash).
  • SubscribeInvoices
    • Creates a uni-directional stream which receives async notifications as the daemon settles invoices
  • ListPayments
    • List all outgoing Lightning payments the daemon has made.
  • DescribeGraph
    • Returns a description of the known channel graph from the PoV of the node.
  • GetChanInfo
    • Returns information for a specific channel identified by channel ID.
  • GetNodeInfo
    • Returns information for a particular node identified by its identity public key.
  • QueryRoute
    • Queries for a possible route to a target peer which can carry a certain amount of payment.
  • GetNetworkInfo
    • Returns some network level statistics.
  • SetAlias
    • Sets the node alias which is to be advertised on the network.
