# clightning-dumpkeys
Dump funding wallet xpubs and xprv from your clightning node.
**WARNING** just saving your xprvs is not enough to backup your
clightning node. There are other channel state (p2wsh) outputs that are
not dumped here. Please use the recommended backup method provided by
clightning (as of this writing there aren't any, but that should
change soon).
## usage
$ ./clightning-dumpkeys ~/.lightning/hsm_secret
It will dump your root+extended xprv/xpub with [output descriptors](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md):

```
## building
You need to have the `secp256k1` library installed for this to compile
$ make
## output descriptors
You can load your clightning wallet keys into your full node with importmulti.
First, save the `extended public (or private) descriptor` into a
`descriptors.json` file, this will be used for importing into bitcoin-core:
`descriptors.json`:
```json
[
{
"desc": "combo(xpub6AP6WVxrrXWRPpbwPYE9F1nPgBntvMaR1ZQH2vP5snNMWGdr4zd7ugwp3wukcTUxKu2rLCN9VBQAW3xioATnEWjZvQpx9cybj1jztJHJyp7/*)#f64dm6yh",
"keypool": false,
"timestamp": "now",
"watchonly": true,
"internal": false,
"range": [0, 1000]
}
]
```
Change `watchonly` to `false` and `keypool` to `true` if you're using the
extended private descriptor.
`watchonly` means we're only going to watch these addresses, not spend them.
`keypool` adds these keys into bitcoin-cores internal pool of keys, these are
used when creating new addresses from the api, etc.
Now we can import this into bitcoin:
$ bitcoin-cli -named createwallet wallet_name=clightning disable_private_keys=true descriptors=true load_on_startup=true
$ bitcoin-cli -rpcwallet=clightning importdescriptors "$(cat descriptors.json)"
$ bitcoin-cli -rpcwallet=clightning rescanblockchain 503500
