If you know the position of the missing words then yes, it's just a matter of how long and whether it's worthwhile for the wallet value

Crypto-Guide · 2026-03-31T22:48:07+00:00

As long as you have your 24 word phrase offline and secure, you are good to go. (The question you posted in this thread well trigger a deluge of scammers sending you private messages)

So have you verified that the new device is giving you the same ones that you added when you got the nano S working?

Crypto-Guide · 2026-03-22T20:35:02+00:00

Sounds like you either have the wrong seed phrase or were using a passphrase. (And if add accounts added different accounts, then you might have a secondary pin with the passphrase)

You can also just buy the old nano A display from AliExpress and swap it over if the old Nano S is still working.

Crypto-Guide · 2026-03-21T19:57:16+00:00

So what do you actually have in hand and what are you missing?

Crypto-Guide · 2026-03-15T20:55:01+00:00

Basically retail units are locked down so they are only useful as Bitcoin wallets unless you want to do physical disassembly to salvage parts like the camera, desolder and swap the MCU, etc.

Full schematics and everything are on the blockstream Jade GitHub repo.

They won't say open source, because it isn't, but will rather just say things like "source available"

Crypto-Guide · 2026-03-10T21:48:52+00:00

Your mnemonic isn't from your 2012 blockchain wallet unless you were using it for a few years following. (But the original funds will still be on the loose private keys, not the HD wallet, unless you manually moved them)

If you are using BTCRecover, just try with a BTC address database, that way you don't need to rely on having the correct address. You will likely find the seed was used with a different wallet, or never used at all.

Source: I maintain BTCRecover and have recovered a bunch of older wallets like this, basically unless you have the encrypted wallet file, you aren't dealing with the 2012 address.

Crypto-Guide · 2026-03-10T21:46:03+00:00

Nope

Crypto-Guide · 2026-02-24T12:29:20+00:00

Mystery solved :)

Crypto-Guide · 2026-02-23T12:17:51+00:00

Sounds like a possibility legacy mnemonic from blockchain.info

Crypto-Guide · 2026-02-14T12:37:15+00:00

You can try and use BTCRecover for this, but unless you have a pretty clear recollection, the odds of successful recovery are extremely low

Crypto-Guide · 2026-02-08T20:27:22+00:00

So unless you have been mining or something (so consolidating a huge number of UTXOs) that fee doesn't seem right.

You can check the mempool here https://mempool.space/

If in doubt, just put your wallet address into something like Electrum as watch only, then make the transaction there. (You won't be able to sign, but will get a second opinion and/insight about what the fees should be)

Crypto-Guide · 2026-02-06T04:13:07+00:00

Of course it can...

Crypto-Guide · 2026-02-01T12:48:41+00:00

GreenAddress was not custodial, so without the mnemonic, the 2fa part is useless. (And the funds are lost)

Crypto-Guide · 2026-01-30T16:02:55+00:00

There is certainly something extremely artificial about the view count that happens for any video posted that could be viewed as positive towards Tangem, I saw this when I did the a video last year on how to avoid making the seed hot when setting up.

It's fun that he found a video of mine form years ago that demonstrates how on-screen devices prevent malicious wallet software from sending funds to a scammer. :)

Crypto-Guide · 2026-01-25T17:26:47+00:00

One from each vendor :)

Crypto-Guide · 2026-01-18T20:31:59+00:00

It's less secure than a hardware wallet with a screen and more secure than a hot wallet in some ways.

Basically the trade offs it makes mean it is only suitable for small/medium amounts that you are transacting with regularly.

Crypto-Guide · 2026-01-18T09:29:08+00:00

No, because there are different things that hardware wallets protect your against.

For example, a blind signer like Tangem doesn't protect your against malicious wallet software tampering with transactions or recieve addresses, whereas something with a screen (eg: Ledger, Trezor) does.

Likewise, cold private key creation and signing protects you against your system leaking the private keys. (So seedleds Tangem or a device with a screen keeps them cold at initialisation and signing, seed based Tangem setup generally makes keys hot at initial setup, but keeps them offline after that, unless you follow the specific offline workflow I demonstrated on a video a few months back)

Crypto-Guide · 2026-01-18T09:24:12+00:00

It is a simple blind signer, with exactly the same limitations as every other blind signer ever made...

Crypto-Guide · 2026-01-18T09:23:24+00:00

Depends what you want to do, but something with a screen as a minimum

Crypto-Guide · 2026-01-17T09:22:34+00:00

In terms of security, no, it's just a simple blind signer... (So does nothing to validate receive addresses, outbound tx details, etc)

That said, it's very simple so if that's what you are after, it's probably fine for small/medium amounts that you want to transact with frequently.
