Title: Partial seed recovery Post by: BigFatYellowLion on November 13, 2018, 08:34:06 PM Hi All,
Apologize in advance if this is not the right forum to post this question. I lost my Trazor + seed. I remember the last 3 words of my seed. How physible it is to be able to brute force the other missing words? Thank you!

There will be someone here with more knowledge to help you who knows of the bio39/44 derivation path however, I’d say from the start of it that you shouldn’t have much hope in getting those coins back as three words isn’t much to go on... Title: Re: Partial seed recovery Post by: LoyceV on November 13, 2018, 08:56:55 PM Trezor uses 24 words by default. If you know only 3, there's no chance of recovery.
Electrum uses 12 words, and that too can't be brute-forced. Each additional word adds 2048 possibilities, 2048^21 is impossible. If there's no way to recover your seed words, your only chance is to find back your Trezor. Title: Re: Partial seed recovery Post by: DireWolfM14 on November 14, 2018, 01:13:24 AM 2048^21 is impossible. If one had a super fast GPU/FPGA rig, say 600MH/S, and assuming one potential combination equals one hash, by my calculations it should take 1.823e+53 years. I don't know how much value the OP had stored in the Trezor, but the cost of running that server for that long might not be a financially sound decision. And then there's the pesky theory that the sun will swallow the earth in a mere 4 billion years.

If bruteforcing a hardware wallet were so easy no one would be using them in the first place.
