Topic: How to Create my own 12 Seed ? (Read 104 times)

The random hand picking I was even talking about was from the 2048 Bip39 wordlist which would be correct only if the last word which contains the bits for the checksum is valid. I don’t know for ioncoleman tool but even if the person picks different words and is able to calculate the checksum and picking the valid word then the seed phrase would be correct. But just as you have pointed out there is also the issue of it been random enough

Iancoleman seed generation is a javaScript web based tool, so it is not an ideal tool for generating wallets, nor does it provide the features of traditional wallets that enable you to customize fee options, coincontrol, and other features, so instead of using a tool for a purpose other than what it was intended for, why not use Electrum.

We are talking here about tips for beginners, and since there are many settings in Iancoleman, it is better not to recommend it to beginners.

First of all, I will not recommend iancoleman for seed phrase generation because of the reason stated by hosseinimr93. Seed phrase generation through JavaScript is not secure. Second, if you want to make use of it like for regeneration of keys and addresses of the seed phrase you generated elsewhere but needs some information which is possible on iancoleman, it is better to use its html file on an airgapped device.

To save fee, use the addresses that start from bc1. They are BIP84 (bc1q prifix) and BIP86 (bc1p prefix).

It will only be an invalid seed phrase on iancoleman if you pick the word yourself. It will display invalid mnemonic.

To be honest this is still not a proper way, you don’t need to hand pick the words of your seed phrase by yourself just because you are familiar with them. Seed phrase are not meant to be remembered but to be written down for back up using your own words simply means you’re trusting keeping it on your mind more. It is not that the randomness will be different but if you pick your words yourself from the 2048 wordlist there is a chance that you will be picking words that you use regularly and someone close to you can easily dictate that which is bad. If there is anything you should be adding to your seed phrase it should be a pass phrase, allow the seed phrase generation to be done by the wallet it self

That's a double negative so I demand you PM me your seed immediately.  Or maybe not.  
One shouldn't trust anything else to create one's private seed, except randomess.

Here's what I recommend you use to generate your next seed.

Just shuffle that deck like your bitcoin depended on it, because it does.

I also think that it's ok for you to generate your own seed phrase, atleast it'll give you the privilege of choosing your own personal words, other than that I don't think that there's any other relevance to it, I think that it'll be better for you to use the seed that the wallet randomly picked. I've never heard of any seed phrase that wallets generated to be compromised from the wallets sides, so for extra layers of security you can use custom seeds generated by reputable wallets like electrum. We're just expressing personal opinions here, it's up to the OP to decide what he wants, if he wants to create his own seed phrase, then there's nothing stopping him.

Iancoleman is a good tool for deriving your addresses, private keys, etc from your seed phrase, if it's used on an air-gapped device, but since it generates the seed phrase through javaScript, I would never recommend anyone to use it for generating a wallet.
For more information on why it's not a good idea to use JavaScript for generating a wallet, click here and read gmaxwell's explanation.

Disconnecting from the Internet doesn't automatically make your device a secure place for generating sensitive data like seed phrases. It may well be that you already had a piece of malware sitting around in your system, and now it is just waiting for the connection to resume to steal all your data and send it to the hacker's server. A hardware wallet is still a better choice than any other because it allows for the safe generation of seed phrases without a user having to set up separate cold storage on a device that has never touched public networks.

BIP32: is the old derivation path that just explains the derivation of child keys from the parent keys and a bit more technical to understand.

BIP44: this is the derivation path used when you want to generate legacy addresses (P2PKH), these are address starting from 1

BIP49: this is the derivation path for nested SegWit addresss (P2SH) or address with prefixes of 3

BIP84: is the derivative path for native SegWit addresses (P2PWKH) or address format starting with bc1q and there is also the BIP86 for taproot addresses (P2TR), the newest form of addresses.

So this all depends on the type of address you want, but as you know the most common address type this days is either Native segwit (bc1q) or taproot (bc1p) because of many features most especially for lesser transaction fee.

 Now to your overall guide I don’t say it is bad but it will be better you generate your seed phrase from any of the reputable wallets you want to use rather than personally generating it with a tool, a mistake might occur from your end in picking this paths. If better you can use custom seeds generated by the likes of electrum to make it unique.

Keep it simple when generating your seed and when backing it up, don’t encrypt anything online just use an offline backup.

Maybe this can be helpful for other people too

so im following this Tutorial
1. Visit Ian Coleman's BIP39 tool website: https://iancoleman.io/bip39/
2. Disconnect your device from the internet for added security.
3. Scroll down to the "Generate" section on the BIP39 tool page.
4. Select the number of words you want in your seed phrase (in this case, 12 words).
5. Click on the "Generate" button to create a new random 12-word seed phrase.
6. Write down the 12 words in the exact order they are displayed. This is your seed phrase that can be used to recover your Bitcoin wallet.
7. Store the seed phrase securely in multiple locations, such as a physical paper backup or encrypted digital storage.

But when it comes to choosing the Derivation Path
BIP32
BIP44
BIP49
BIP84
BIP141

Which one should i choose , and will my bitcoin be secure ?
(ofc not sharing my seed with no one )
