Trying to recover bitcoin from a legacy address given out by a trezor circa 2017

[larry_vw_1955]

Wait a minute. You said that the coins were visible in an address when you imported it into a watch-only Electrum wallet. So why don't you try playing around with the derivation path on both seeds to change it to ones that could be probable Trezor paths? It's basically the first 3 numbers you need to manipulate. It goes down to the second and third numbers if you know the address prefix which you seem to know: Paths start with 44, 49 and 84 (I believe they are all hardened) for 1, 3 and bc1 addresses respectively.

He knows the bitcoin address lol. i the question is, did his sister or whoever she was how did she get that address into her trezor?? i doubt she would know how to create a watch only wallet and even if she did know how, why would she do that and where would she get the particular bitcoin address from to do that? the mystery deepens...

OP, have you perhaps overlooked this suggestion?
I also think that this could help you, but to better understand what happened to your transaction. It's official Trezor app https://suite.trezor.io/

Have you been using the Trezor Suite or the wallet.trezor.io website to connect up the Trezor and investigate the available accounts?

So I am left scratching my head.

You and me both...

The 3 bitcoin are in the address they sent me in their email back in 2017. They say it came from the Trezor One.  They say they saw the 3 bitcoin I sent back to them show up in the "Legacy Account" on the Trezor One but that they were greyed out.  They were unable to send them any where.  Then after they updated the firmware they claim the bitcoins quit showing up in the legacy account even as greyed out ones. 

I'm still confused as to how the address and/or balance would show up in the Trezor wallet (greyed out or otherwise) without being able to be to used and/or recreated when the wallet is restored.

Trezor, both the web version and the newer Trezor Suite, does NOT allow you to import addresses or private keys etc. You cannot create a wallet without the device. The web version would essentially recreate the wallet every time you started it up and unlocked your device.

It's certainly not something I've seen while using a Trezor... and I don't recall any similar cases either.

you haven't come across anyone that said they couldn't see their legacy wallet? i think it have to do with segwit and trezor dont like to showing legacy it preferred to using segwit.

I am beginning to think that they acquired the address from some other source and not their Trezor One.  They are quite certain this is not the case.  They assure me they had no other wallets or accounts other then Coinbase and they are not there.

Are you certain that you've sent Bitcoin (BTC) to your sister and not Bitcoin Cash (BCH)?
Because in 2017, BCH's address is the same as Bitcoin's legacy address; thinking you/she might have remembered it incorrectly and it's Bitcoin Cash all along.

That's easy to test: enter the address into Blockchair.com's search field. It will tell you on which chain(s) it has funds.

No... I mean I haven't seen any cases of someone who had a "greyed out" legacy account that they were unable to send funds from, that disappeared after they updated their firmware and/or reset their device etc.

You are correct that Trezor doesn't "show" the list of Legacy accounts by default... but it shows the "Legacy Account" menu item and if you expand the menu item, it does show any existing "Legacy Accounts" with balance and transaction history. You don't have to explicitly go searching for them.


Unfortunately, what we're left with is that we're essentially "guessing" based on a 2nd hand description of something that happened 3-4 years ago.

Could this be a case of a passphrased account? OP's sister added the passphrased account to their Trezor software (perhaps without even realizing they had used a passphrase), and then every time from then on they attached their Trezor (without the passphrase) the account in question was still displayed but inaccessible. Difficult to test given we don't know what version of software they were using.

[HCP]

Fairly sure that the wallet.trezor.io system didn't store "state"... and it certainly doesn't now. So, as soon as you unplug the device, everything is "forgotten". When you reconnect and unlock the device, then it does the account discovery again.

Difficult to test given we don't know what version of software they were using.

I've certainly never seen it show both "default" and "passphrased" accounts in the UI at the same time... and I've had my Trezor since 2016. But yes... it's possible that this behaviour changed at some point between then and now.

Trezor is open source right? So if someone wanted to they could inspect the source code to figure out under what conditions a legacy account will become "greyed out". then we could know what was really going on. Should be a very simple matter.
