You can't.

Bitcoin Core is not BIP39 compliant.

  • To note, this is not a bad thing. Bitcoin Core is also not compliant with regulations on PPE, but that doesn't not taint it as a software product. – Claris Sep 02 '20 at 13:03
  • One still get and store the hd seed key of a wallet in it's WIF encoding. Use dumpwallet and then check the file for hdseed=1. – tread Dec 10 '23 at 01:20

How to get my 24 word seed using bitcoin-cli

You write about getting but your commands are about setting. This is confusing.

You can't get a seed-phrase from Bitcoin-core.

You can use the sethdseed function to "Set or generate a new HD wallet seed." this marks any existing private keys as inactive (which may or may not be what you want).

Note that an HD seed and a (24 word) seed phrase are different things.

I've tried: bitcoin-cli sethdseed 'word1 word2 ...' but i got invalid private key.

I think that may be because the second argument is not a seed phrase but a WIF key.

  1. "seed" (string, optional) The WIF private key to use as the new HD seed;

  • Sorry Asking dumb questions but how can i convert my hdseed to a mnemonic phrase. – Erfan Sep 04 '20 at 11:12
  • @Erfan. There's no need. Instead people changing from Bitcoin core to another wallet usually export the private key and tell the new wallet to sweep the key. – RedGrittyBrick Sep 04 '20 at 11:38
