-snip- using some of the seed phrases, so now I'm trying to figure out what configurations to use in the wallet recovery option with Electrum to retrieve those wallets because there are custom words in them that I put in there for if this issue arises.
This is what the first reply meant that it doesn't make sense: wallets don't use seed phrase back in 2009~2011 (
and Electrum was experimental in December 2011).
Additionally, even if you've used old Electrum past December 2011, its old type seed phrase isn't capable of adding "
custom words"; '13th word', 'seed phrase extension' or 'passphrase'.
And if it's from the very first experimental versions of Electrum, its backup was not even a mnemonic.
Let's disregard the date, if you truly think that the 12 words that you have is from Electrum (
electrum.org):
Simply restore it via "
Standard->I already have a seed" new wallet option.
Even the latest version of Electrum will recognize an old Electrum 12-word seed as "
Seed Type: old" below the text field.
Ticking "
Extend this seed with custom words" in the option wont trigger the custom words text field if the seed phrase is detected as old electrum seed.
If it's indeed detected as old seed, you're on the right track.
BTW, I saw your other thread.
Self-custodial wallets like Bitcoin Core, Electrum, and usually those that have a seed phrase don't store your funds in a server nor owned by their developers.
The private keys are in your device and/or backed up by the seed phase so the best help that you can get from them or others are just as good as getting instructions on how to do it yourself.
Lastly, please don't PM me regarding this.
