Topic: Create Bitcoin Core hd wallet from word list / mnemonic (Read 322 times)
UPD: Resolved. It needs to use -v 239 for testnet in bx ec-to-wif command
Hello all!
I'm trying understand HD wallets in bitcoin core implementation and got stuck. Here it is:
$ bx seed | bx mnemonic-new -l en
reward awake later spot grass list peanut clog hurry guess question father leg dress only reunion horn napkin
$ echo "reward awake later spot grass list peanut clog hurry guess question father leg dress only reunion horn napkin" | bx mnemonic-to-seed | bx hd-new | bx hd-to-ec | bx ec-to-wif
L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG
That WIF key L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG should be ok for sethdseed? Right?
So next:
$ bitcoin-cli createwallet test
{
"name": "test",
"warning": ""
}
$ bitcoin-cli -rpcwallet=test sethdseed true L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG
error code: -5
error message:
Invalid private key
What's wrong?
Thanks in advance.

i wonder why you use mnemonic seed with 18 words which isn't common?
The readme was misleading: 9, 12, 15, 18 or 21 words are fine (everything that "bx mnemonic-to-seed" accepts as input).
To have a way of (re-)creating Bitcoin Core wallets out of a word list I wrote a bash script.

How it works:
This can basically be done with two lines in the terminal:
A random word list can also be created with Bitcoin Explorer:
The script provides some extra convenience. Hope it's useful.

How it works:
- Bitcoin Core allows you to create a deterministic wallet from a seed
- Bitcoin Explorer allows you create such seeds from a word list
This can basically be done with two lines in the terminal:
Code:
$ echo "my random and secret word list" | bx mnemonic-to-seed | bx hd-new | bx hd-to-ec | bx ec-to-wif
L26zbMQRXyhUaaHcTQ13mzHWBauMPsG2qrmZQHx5QpYmMMFkhcWn
$ bitcoin-cli sethdseed true "L26zbMQRXyhUaaHcTQ13mzHWBauMPsG2qrmZQHx5QpYmMMFkhcWn"
L26zbMQRXyhUaaHcTQ13mzHWBauMPsG2qrmZQHx5QpYmMMFkhcWn
$ bitcoin-cli sethdseed true "L26zbMQRXyhUaaHcTQ13mzHWBauMPsG2qrmZQHx5QpYmMMFkhcWn"
A random word list can also be created with Bitcoin Explorer:
Code:
$ bx seed | bx mnemonic-new
sadness arrow artefact expect office carry fatal tape radar ladder dirt hawk echo bone exile uphold topple local
