There is currently no way I could find that someone could extract a private key out of a Ledger wallet. So if someone steals your Ledger today, they should not be able to spend your coins. However, since the private keys are physically stored in the device, someone successfully extracting them isn't a question of "if" but "when". In case ...

Yes, you can. The transaction will just not be a SegWit transaction, and not receive its benefits (including lower fees for a given confirmation speed).

Using words to back up wallets is a process described in BIP 39. Basically, the mnemonic is converted into a seed. This seed is then used as the seed to a Heirarchical Deterministic (HD) wallet, as laid out in BIP 32. The seed is used to generate a Master Extended Private Key, from which all other private keys can be generated. The child key generation ...

From Michał Zabielski's comment: Unfortunately you are out of luck. Never share your word phrase with anyone. If you do, you effectively give access to your money to someone else. If someone asks you about your word phrase (or anything related to private keys) you can be pretty sure that it’s a scam. To clarify, the device's security was not breached. In ...

I understand these wallets only work with provider's mobile app, online interface or their computer software, correct ? No. Some of the most popular hardware wallets are supported by third party software. For example, Trezors and Ledgers can be used with Electrum who have implemented support for these devices directly. Other wallet software like Wasabi ...

Yes, by using the same seed phrase (and derivation path), you can have multiple instances of the same wallet. A wallet does not 'contain your bitcoin', it just contains the keys that allow you to spend your bitcoin. So you can create multiple wallets that hold those same keys, and then use any of those wallets to perform wallet functions (like sending, ...

It is a common misconception that there are actual objects or chunks of data that are Bitcoin and that your wallet receives. That is actually not the case; your Bitcoin are just values attached to outputs created by previous transactions. Most of these outputs (and the type that your Ledger is designed for) require that the spending transaction contain a ...

Find the HD Public key for your wallets: Open the Ledger Wallet Chrome bitcoin app Click your account in the overview, it’s called “My account” by default Click “Account Settings” in the top right corner, under the balance Click “Export” next to “Extended public key” And when you see the QR code pop, you’re ready to begin the next part. You can test the ...

From BIP39:"A user may decide to protect their mnemonic with a passphrase. If a passphrase is not present, an empty string "" is used instead." The passphrase can be added in the transformation from the mnemonic phrase to the seed. It is not added IN the mnemonic but in an other point of the procedure. A consequence of this is that: "The described method ...

Ledger uses a secure element chip to store the private key. In simplified terms this means that the private key is stored on a special chip that is almost like a small computer with a Operating System with a very strict and well defined interface. This interface is designed to NEVER allow an extraction of the private key except during the creation of the ...

Wouldn't it be saver to generate a mnemonic passphrase manually by just taking random words from a lookup table? No, it would not be. This method may even be insecure if you are actually doing it manually. A BIP 39 mnemonic, if generated properly, is secure. It is just as secure if you randomly choose words too. This is because both methods require a ...

If LBC is somehow able to guess anyone's private key, regardless of how the private key is normally stored and generated, then yes, they can just spend the coins. All you need is the private key, it does not matter how the key was obtained. Of course this is impossible to do in practice with today's technology. The range of possible private keys is ...

You can use them, but you need to ensure that the hardware wallets use the same address derivation paths. For the hardware wallets you mentioned (Trezor and Ledger) both of them use the BIP 39/BIP 44 derivation paths, so that should work, especially in the case of Bitcoin. However care has to be taken for certain coins (ETH or any other ERC-20 for example) ...

There's distinction of "bitcoin" and "bitcoin segwit". It's just Bitcoin.

I have a HW.1 too. I purchased mine, so it came with the recovery card. If you have your recovery card, you might be able to contact their support and ask how you could convert your security card's details into the 16 byte key If you can't do this, then use the link you posted previously to generate a random key, and then generate your card. Remember to ...

The ledger_index is the 256-bit index of a particular entry in the ledger. The ledger's state tree is a hash tree of index/value pairs. Each index is a 256-bit hash of some kind of locator. If the entry is, say, an account root node, the index is a hash of the 160-bit account ID. If the entry is, say, a ripple balance node, the index is a hash of the two ...

Those are valid mnemonics with valid checksums. In the bip39 spec is the following: The following table describes the relation between the initial entropy length (ENT), the checksum length (CS) and the length of the generated mnemonic sentence (MS) in words. CS = ENT / 32 MS = (ENT + CS) / 11 | ENT | CS | ENT+CS | MS | +-------+----+------...

Yes, you can use a single Ledger for multiple coins. Here is the list of supported coins.

You need to update the udev rules (on the guest OS) with this command: wget -q -O - https://raw.githubusercontent.com/LedgerHQ/udev-rules/master/add_udev_rules.sh | sudo bash It works, I verified it. source: https://support.ledgerwallet.com/hc/en-us/articles/115005165269

when the address to give me my change showed up on my Ledger nano wallet I hit the x instead of the check mark. I don't think I got my change That is not how a transaction works, if you did indeed send a transaction, the change would be returned to you automatically. There would be no additional steps required for you to ‘claim your change’, that simply isn’...

You can't. Bitcoin Core currently does not support importing extended public keys.

Bitocin Core does not support importing xPub but it does support importing batches of addresses. You can generate a large set of addresses from the xpub (external, change etc.) and import them with one call importmulti

No. Secure elements are designed to be resistant to physical attacks. So you shouldn't be able to do anything physical to the chip that allows you to get data off of it. They are designed to prevent unauthorized access to their data so they also are more than just storage devices. While you can desolder the chip and attach wires to its pins in order to ...

With an 8-digit PIN, the number of possible PIN combinations is 10^8 (100,000,000), ranging from 00000000 to 99999999. So you chance of just guessing the PIN correctly within three tries is about 1 in 33,333,333. So it is of course possible, but extremely unlikely. Note that an attacker could perhaps increase their chances by eliminating some possibilities ...

Yes, you can have multiple bitcoin wallets in ledger nano x by adding a new account All these accounts share the same seed, but have different derivation path

Ledger Wallet doesn't support RBF but you can do Child Pays For Parent: Make a transaction to your address 3M6EhQL3QUQHAFkSPH3vLc3VDCrJKP3iMv with amount 0.011, set a fee rate, preview the transaction and check and confirm the transaction only if one of the inputs is 0.01187067 BTC. If this doesn't work, download Electrum and CPFP from there. But honestly, ...

Your understanding is largely correct. I'll nitpick a few points for clarity, but overall I would say you have a decent grasp of whats going on here. I can send the X BTC I purchased to my hardware wallet by giving the public key to my hardware wallet and specifying perhaps .99X BTC go to that wallet and the remaining .01 BTC is left as the transaction fee. ...

Here is my understanding - please let me know if any-step is incorrect. All correct. Since my computer is not a node, how does my client software "send the message to the network". I presume I need to be connected to wifi. Then what? Ledger Live, I believe, just connects to Ledger's service, and it uses Ledger's node. If you care about privacy ...

Third Parties should extend your mnemonic phrase with your passphrase else they will get a different wallet with different addresses. Electrum and some other wallets call the passphrase a "seed extension" or "mnemonic extension". Third parties should have an option to extend mnemonic phrase with your passphrase, It's a weird idea to possibly have enough ...
