### Overview

A multi channel funding, multi target withdraw plugin for c-lightning.

0.7.1 release of clightning allows opening of multiple channels with a single transaction.

This plugin adds RPC commands to take advantage of this.  Also, withdrawing funds to multiple

locations is a very similar process, except you know the destinations beforehand and you skip

the channel part, so it seemed logical to add as well.

### Usage

Currently there are 2 new RPC commands for channel funding using either bitcoin core wallet or lightning **internal wallet**

`fund_multi` and `connect_fund_multi`

`fund_multi [{"id": "02fc...", "satoshi": 20000, "announce", true}, {...}, ...]`

`connect_fund_multi` adds `"host"` and `"port"` parameters to the above

For use with an **external wallet**

`fund_multi_start` same format as `fund_multi`

This will return the addresses to be used for transaction creation in external wallet.

Once the transaction is created and signed with eternal wallet call

`fund_multi_complete tx` where tx is the hex string of the signed transaction.

This will line up the addresses and index in the transaction and complete channel funding (internal call to `fundchannel_complete`)

and broadcast the transaction

Also one command has been added for multi destination **withdraw**

`withdraw_multi [{"destination": ADDRESS, "satoshi": n}...]`

provide an array of objects with `destination` and `satoshi` values

### Options

There is one option that can be passed to the lightningd command line. `multi-wallet`.  `--multi-wallet=bitcoin` will use the wallet from the bitcoin core node.  Omitting this option will uset the internal c-lightning wallet, or you can be explicit with `--multi-wallet=internal`

The bitcoin core node is used for broadcasting transactions so it must be accessible even if you use clightning internal wallet.

TODO:

* Allow to set `feerate` and `minconf` on `withdraw_multi` to be consistent with `withdraw`

* Support for bitcoin cookie auth?
