## Creating Recovery Words
One of the big limitations of Bitcoin Core is that it creates a BIP32 HD wallet, but it doesn't provide any way to back that up with BIP39 mnemonic words. With Libwally, you can now do that yourself.
You can dump your wallet with the `dumpwallet` RPC command:
```
$ bitcoin-cli dumpwallet seed
{
"filename": "/home/standup/.bitcoin/seed"
}
```
If you read the file you created, you should see your seed with the line `hdseed=1`
```
standup@btctest:~/.bitcoin$ more seed | grep hdseed

```
The following command will currently work to extract that seed, though this type of command depending on file formatting is always prone to breaking as file formats change:
```
seed=$(cat seed | grep hdseed=1 | awk '{print $1}')
```
Now, you just need to import that into a simple Libwally program.

[write a script that (1) dumps; (2) extracts the key; (3) runs it through libwally; (4) outputs the mnemonic words]
