Title: [SOLVED] Accessing an old BTC wallet without .dat Post by: UserU on April 12, 2025, 08:45:38 AM While going through some old storage, I happened to stumble across a notepad I saved in 2013 with the 12-word seed/ recovery phrase and the password. Unfortunately I don't have the .dat file and can't remember which wallet it was originally created on (Bitcoin Core doesn't seem to support restoration without .dat)
Now the problem is that over 50% of those phrases (e.g. sock) are not BIP39 compliant, so I'm wondering if there's another way. I tried the Blockchain.org/ com wallet recovery webpage but that didn't work.

Multibit HD did, but that should be BIP39. Maybe Electrum (not sure when they first started supporting seedphrases) but it doesn't hurt to try.

If you did not, let's try it. Remember to use it offline.

This word_list has that word, but given that there's tens of thousands in the list, it may be a coincidence.Archived mnemonic_words_v3.txt: web.archive.org/web/20240922032019/https://login.blockchain.com/legacy-pages/js/mnemonic/mnemonic_words_v3.txt (https://web.archive.org/web/20240922032019/https://login.blockchain.com/legacy-pages/js/mnemonic/mnemonic_words_v3.txt) Check if every word in your phrases are available there. However, there's no known method of recovering the account information that can be restored from mnemonic phrase generated from that list.

Multibit HD did, but that should be BIP39. Maybe Electrum (not sure when they first started supporting seedphrases) but it doesn't hurt to try. I tried Electrum and seems that they support the BIP32 (which is the case for mine) protocol. Alas, just an empty wallet after unlocking it. Nevertheless, thanks for the help!

Hey, I was gonna try yours until I started with Omega's suggestion and that did the trick. Thanks for your input :) This word_list has that word, but given that there's tens of thousands in the list, it may be a coincidence.

Great find! :) I did manage to recover my wallet, but apparently a big fat |
