Searching for Electrum Wallet File Insights

I think the wallet.dat is in this data: dat 0 \x61\x15\x06\x00 and so on. Not sure if that's all of it, but I believe the Electrum wallet from 2013 might be named electrum.dat before it became default_wallet. I found some magic numbers too, but you might laugh at my guesses lol.

Not totally sure about your hex stuff, but "addr_history" sounds like a good lead. It's a key string in the Electrum 1.6.1 JSON that was the last version out in 2013. If you look there, you might find what you're after. Also, did you think about moving this thread to the Electrum board? Just a thought.

The filename should stick with.dat like bitcoin core uses. Default is definitely electrum.dat, and renaming in the client isn’t an option unless it’s been changed elsewhere. Also, your offset checks out since you start with the first hex value. The signature you mentioned, 0x7B27616464725F686973746F7279273A, might be on point. I'd suggest checking for that! Just trying to help, good luck!
