Have you ever seen a bitcoin address like below
3MyCoinoA167kmgPprAidSvv5NoM3Nh6N3
bc1quantum898l8mx5pkvq2x250kkqsj7enpx3u4yt

If you want to create a vanity address like that so here the steps

---

---

1. Download Vanitysearch

You can download the latest VanitySearch 1.14 (https://github.com/JeanLucPons/VanitySearch/releases)
https://i.imgur.com/ifZYkFr.png

---

2. Turn off internet connection while generating your Bitcoin address

It’s also possible to create a vanity address when your internet connection is active, but for security reasons no internet connection is recommended. It would be even safer if you run the program on a computer that was never connected to the internet, but you can decide for yourself which security level is sufficient. It's always recommended to prefer high security standards to avoid any problems resulted by hacks because it's always possible that your device is compromised.
If you want maximal security you can generate your vanity address via split-key (https://en.bitcoin.it/wiki/Split-key_vanity_address) (Here the tutorials https://bitcointalk.org/index.php?topic=5144752.msg51126883#msg51126883).

---

3. Open Command Prompt

You can start the Command Prompt by a right-click on the Windows icon in the lower left corner of your screen and select Command Prompt (Administrator) or simply using the key combination Windows + R.

or

if you do it like that you can skip #4 if you open the command prompt directly from where your vanity files are stored:


- Go to the folder where vanitysearch is stored.
- Press CTRL+SHIFT+RightClick on an empty space within the folder (not on the executable/files), click "Open command window here". Now the command prompt opens.

(source: nc50lc (https://bitcointalk.org/index.php?topic=5096373.msg50208980#msg50208980))

---

4. Enter Path

The paths depend on where you have stored your VanitySearch files. I have saved these on E:\ in the folder Vanity. I have to enter the following code to find the vanitysearch.exe file:

C:\users\MSI>E:
E:\ cd vanity
E:\Vanity>vanitysearch.exe

Folder Vanity
File name vanitysearch.exe

5. Creating The Vanity Address

Here the list of parameters that you can use to create the vanity Address:
https://i.imgur.com/2bPF7tm.png

For this Tutor,  i want to create the 3FERY and bc1qfery address. But you need to know that not all characters are supported for SegWit addresses:

In addition to 0, O, I and l are not allowed:

Nested SegWit (3...) has to start with an uppercase letter or a number. For example, 3Fery works but 3fery not.
Native SegWit (bc1q...) doesn' support the letters / numbers 1 (except the 1 in bc1q), b, i and o. (1) (https://bitcointalk.org/index.php?topic=5144752.msg51114964#msg51114964)

To create the 3FERY and bc1qfery address, so we need the following commands

Your Command should be like this


if you already type the command above then press enter. if vanitysearch has done searching your address then it will look like this
https://i.imgur.com/SBcTgwi.png

and your Private Key will be stored into file save.txt in the same folder as VanitySearch
https://i.imgur.com/1UH5u3y.png

Tada and here the address that i already created before
segwit: 3FERYMacdfMG7X6u75JEnxUD8LqqLiQeWK (https://btc.com/3FERYMacdfMG7X6u75JEnxUD8LqqLiQeWK)
bech32: bc1qferyrvvz0u3wkxcc2gj3v9595j4qrjmddmsvzm (https://btc.com/bc1qferyrvvz0u3wkxcc2gj3v9595j4qrjmddmsvzm)

---

6. Save your generated public and private key

Security is always very important when it comes to Bitcoin. Keep your generated private key very safe, because it’s like the password to your Bitcoins. You can write it down on a sheet of paper, store it in a safe place and save it also on a USB stick that you only use for your private keys.

---

7. Done!

Now, you have successfully created your own Bitcoin address. If you want to access it (like via Electrum) you can have a look here (https://bitcointalk.org/index.php?topic=5096376.0)

in addition, i already creates my own vanity address
1FfFfFf26sVGsGKaR2MxNWESRhnDHdVBz
3FERY5GPg4e1KwxXPKb2pb46tntR44U3st
bc1qferyj60j2ecmlsh3tld256spe0zn3s7n6uf0z4

Very well explained!
I created some SegWit vanity addresses just a few days ago for my hot wallet (3HotfU4tPCaQdBE98WmYcmDzeC8C8UAx3F (https://btc.com/3HotfU4tPCaQdBE98WmYcmDzeC8C8UAx3F)) and VanitySearch is just awesome. So much faster than vanitygen and SegWit addresses are possible.

But I noticed some additional "restrictions" for SegWit addresses, maybe you can add them:

Nested SegWit (3...) has to start with an uppercase letter or a number. For example 3Fery works but 3fery not.
Native SegWit (bc1q...) has some more "restrictions" and in addition to O, 0, I and l the letters / numbers 1 (except the 1 in bc1q), b, i and o won't work. So sad that I can't create bc1qmiau...  :'(

Would you mind adding information about obtaining a private key using the split key method? It's very useful if one doesn't have a powerful PC and want someone else to find the desired address. It's used by Loyce and DarkStar in this thread (https://bitcointalk.org/index.php?topic=1813624.msg51105612#msg51105612).

Oke i will try to make the tutor for creating vanity address using the split key method. Maybe it will be done tomorrow.

You've already linked to 1miau's thread which includes a section on being offline, but I think it would be worthwhile for you to include a similar statement in your own thread. Generating private keys (or even having private keys stored) on a computer with an active internet connection is a big security risk. At a minimum you should be running this program offline, but preferably on a permanently air-gapped device. If your air-gapped device isn't powerful enough to generate an address in a reasonable amount of time, then you can at least generate a split key whilst air-gapped.

thank you i already add the part that we can generate an address while offline.
For the split key, i will try to make the tutorials later

because I see there are some people suggest making a tutorial about generating an address by using split-key.
The steps almost the same until in option 5 in this thread, so below are the steps

---

---

Generate a vanity address for a third party using split-key

as in this tutorials, i will take "fery" as the person that wants to create an address and "Jhie" as the person that creates the address using split-key

---

---

1. Generate Key Pair

Fery needs to generate a key pair in his computer then send to Jhie with the prefix bc1qtut0r.
So fery needs the following commands:


so the commands should be like this:


if you already type the command above then press enter. if vanitysearch has done searching Key Pair then it will look like this
https://i.imgur.com/xFd9gwF.png

then save the generate key pair into a notepad

---

---

2. Generate the Address

After Fery found the Public Key, he needs to send it to Jhie so he will start the vanitysearch using Fery Public Key and the wanted Prefix (bc1qtut0r)
so Jhie needs the following commands:

so the commands should be like this:


if you already type the command above then press enter. if vanitysearch has done searching Partial Private Key then it will look like this
https://i.imgur.com/a7QYtfd.png

after that, it will generate a new file in the folder "keyinfo.txt" that contain a partial private key and the file will look like this
https://i.imgur.com/V58bY05.png

After Jhie generate the partial key he will send it to Fery

---

---

3. Generate the Final Private Key

After Fery received the partial Private key he needs to make a notepad file with the private key in it. In this case, we will still use the file keyinfo.txt.
Then Fery will reconstruct the final private key using her private key (the one generated in step 1) and the partial private key that we saved in keyinfo.txt

So Fery Needs the following Command:


so the commands should be like this:

if you already type the command above then press enter. the final Private key will be shown and it will look like this

https://i.imgur.com/k2Xt1G7.png

Don't forget to save the private key

---

---

4. Done!

Now, you have successfully created your own Bitcoin address. If you want to access it (like via Electrum) you can have a look here (https://bitcointalk.org/index.php?topic=5096376.0)

i made a bech32 key with vanitysearch and imported the wif into bitcoin-qt 0.18.0 but it ends up giving me the old style with the 1 prefix.  i have bech32 enabled as default in the options; if i let the wallet generate a random key for me it is bech32.  so how to import a key as bech32 ?

you must import the private key full like "p2wpkh-p2sh:5priv.key" or "p2wpkh:5priv.key"

AFAIK this will only work with Electrum.
Have you tried this prefix method with Bitcoin-qt or Bitcoin Core?

Try this guide: [GUIDE] Importing Electrum Segwit Private Key Into Bitcoin Core (And Vice Versa) (https://bitcointalk.org/index.php?topic=3383265.0)

I just try it but it does not work, i try using electrum 3.3.6 and i got this responds back Traceback (most recent call last):
https://i.imgur.com/jkI1wDf.png


I haven't tried it yet with Bitcoin-qt or Bitcoin Core because i don't use it

do this: addwitnessaddress yourOldStyle1PrefixAddress
it should return the bech32 address as a result, which indicates address has been imported successfully

How about this: bc1qml4uujfkgcd7pfzvsukvs9v78l8jh8htea7pjj (https://btc.com/bc1qml4uujfkgcd7pfzvsukvs9v78l8jh8htea7pjj) or bc1qmlauptfw2yhhzaj6pqr2dqt6g409g88x7ytt4a (https://btc.com/bc1qmlauptfw2yhhzaj6pqr2dqt6g409g88x7ytt4a)

use lowercase of (L)

i tried all the things suggested here and nothing worked.  addwitnessaddress command doesnt exist in bitcoin-qt, the electrum script in the other thread just returns p2pkh: prefix to the same private key, and bitcoin-qt does not recognize either p2wpkh: or p2pkh:

maybe it just wont work until a future version of bitcoin-qt

As per post as suggested that it needs a good PC for this to work out. Maybe your PC does not compatible in creating a btc vanity address or try checking the steps again and double check if it has being done correctly. There are times that process might not be followed like forgetting a tiny details in the process.

ok i figured out how to import bech32 in the core client.

  -walletimplicitsegwit
       Support segwit when restoring wallet backups and importing keys
       (default: 0)

if you use that commandline option and import the normal wif as usual it will give you the bech32 pubkey, though when i go to the "receiving keys" window it lists all 3 possibilities, a key with a 1 prefix, another key with a 3 prefix, and the actual bech32 key i am after.  might not be a way to stop it from doing that.. is kind of annoying but whatever

What an unfortunate, can't create even mine as bc1qbL4nk for native but will do on nested one.

nice tutorial managed to create my first vanity segwit address ;D

Unfortunately could not get something close to my name because of the (Unreachable, 31h1 to 3R2c only)"

thought the restriction was for these characters>>" 0, O, I and l are not allowed"

Anyway, now just playing around with this trying to find me some cool address ;D

i saw someone who using bitcoin core or Bitcoin-qt and doing this and his address added into their wallet
the steps below

You just need remove the prefix which indicate address type (p2pkh, p2sh, p2wpkh-p2sh, p2wpkh or p2wph) if you want import private key generated from vanitygen to Bitcoin Core

Yes, looks like it's indeed possible. Lowercase L (l) seems to be allowed in native SegWit while it's not allowed in Legacy and nested SegWit addresses. I'm confused, it's quite easy to confuse an lowercase l and an uppercase I.  :D


I guess you tried to create a nested SegWit address like 3roosbit or 3roos, right?
For nested SegWit your second character needs to be uppercase like 3Roosbit or 3Roos. If the second character after 3.. is lowercase the creation doesn't work.

I believe 3R... prefix is not possible, possible prefix is only up to 3N...
I've asked this in vanitygen thread awhile ago and someone answered like this


edit: I think I was misinformed about the possible prefix :-[
it is possible to find 3R..., but not possible for 3Ro... because the range is up to 3R2c as mentioned by roosbit

Yeah, thanks for the heads-up 3Roosbit won't work unfortunately. Close to it but out of the range  :-\

I've just tried vanitygen P2SH and 3R2c works:

did you just generate an address from vanitygen? as i know that vanitygen don't support segwit address yet

Yes, I created the address 3R2cNJdWKc2zLt26wq2NdaUCgRCgqdDViK from vanitygen, you just need to add -F script for the command.

That's true, but the address from vanitygen isn't SegWit, it's just a simple P2SH (pay to script hash) address. Nested SegWit are P2SH-P2WPKH and that's not possible to create from vanitygen. 
But both addresses, P2SH (non-segwit) and P2SH-P2WPKH (segwit) are starting with 3...

Here's some reference to the original vanitygen discussion:

Are this for x64 windows, correct?
You know how to fix my problem?, got error when to star running

Same here.

Looks like you guys didn't install Visual C++ Redistributable Packages / it's corrupted, you can download it at https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads (https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)
AFAIK you need to download 2015 or 2012 version.

Has anybody tried VanitySearch 1.15 , I kept getting access denied when trying to create a Vanity Address after using this code >> E:\Vanity>vanitysearch.exe -stop -o save.txt 3XXX <<< even after running CMD as an administrator  ???

FYI reverting back to Version 1.14 seems to run without a problem  ::),Am I doing something wrong or version 1.15 is bugged?

I guess the old saying of "If it ain't broke, don't fix it" is what am looking at atm.

I have no problems with that code

Did you download the vanitysearch from JeanLuc github (https://github.com/JeanLucPons/VanitySearch/releases)?

I use code:

Screen result :
https://i.imgur.com/tyB4Ier.png

File result:
https://i.imgur.com/B4oCJ1E.png

PS: I'm using old PC with 4Gb RAM; OS Windows 7 with 2012 Visual C++ Redistributable Packages (https://bitcointalk.org/index.php?topic=5144752.msg51225926#msg51225926)

This is presumably because you don't have permission from Windows to access the files for version 1.15, or the files are not present or corrupted at the address you have entered. I would first delete the program and reinstall it from scratch. Make sure your input in command prompt matches the directory where you have installed it.

If it's still not working, then right click on the "Vanity" folder, hit "Properties" then "Security". Make sure your user account has Read & Execute permissions. You could also try hitting "Advanced", and changing the owner to your own account, making sure to check the box marked "Replace owner on subcontainers and objects".

I have made it following the tutorial above, but I'm still confused because I can't find the Private Key for the address that I created. then where can I find my private key?
does anyone want to tell me.
https://i.imgur.com/coFBkgJ.png
https://i.imgur.com/VedxVbf.png

Your private key is right there in the text file you have shared a screenshot of.

"Priv (WIF)" is your private key in wallet import format.
"Priv (HEX)" is your private key in hexadecimal format.

Most wallets would accept the private key in WIF. The "p2wpkh-p2sh" (pay to witness public key hash - pay to script hash) bit at the start tells your wallet what kind of address it is (nested segwit). The rest of that line (from L537... to ...TtMG) is your actual private key.

---

Obviously you should never ever use that particular private key since you have just shared it online. Generate a new vanity address before importing.

An additional post, because your question already answered by o_e_l_e_o, if you want to import, you need to copy all including p2wpkh-p2sh:

https://i.ibb.co/djYWnPF/image.png (https://ibb.co/BcMz8yb)

https://i.ibb.co/58h5vby/image.png (https://ibb.co/SnwK0F8)

Sorry to reuse your example address

Yes I know, I will not use that address because it is just an example, I am confused about how to import it into the Blockchain wallet.  Is the key above can only be imported into the Electrum wallet?

It can be imported using trezor, bitcoin core, am not really sure about blockchain.com, if you can't import this kind of address, i think they are still not supported p2wpkh-p2sh.

The above key can be imported in to pretty much any wallet, but it will not necessarily give you your vanity address. On blockchain.com you can import keys by clicking on "Settings" in the top right, then "Wallets & Addresses", and then "Import Bitcoin Address".

The same private key is associated with multiple addresses. We can derive a legacy/p2pkh address (starting with a "1"), a nested segwit/p2wpkh-p2sh address (starting with a "3", as in your case), and a native segwit/bech32/p2wpkh address (starting with "bc1"), all from the same private key.

Blockchain.com, as far as I am aware, only supports legacy addresses, so if you import your private key, you will end up with an address which begins with "1" and doesn't look anything like your desired vanity address. You could import the address itself rather than the private key, but then it would be watch only and you wouldn't actually be able to spend the funds.

You have two options here. Either generate a legacy vanity address beginning with a "1" rather than a "3", or use a wallet such as Electrum.

Then how to import from privkey hexadecimal ?

Which wallet are you using, and what type of address (Legacy "1", Nested SegWit "3", or "Native SegWit "bc1") are you trying to import?

Some wallets will accept a private key in hexadecimal, but most will want you to convert it to Wallet Import Format (WIF) first. You can do this using https://www.bitaddress.org/.

You should scroll to the bottom of the page and download the page as a zip, and then run it offline, preferably on a permanently offline computer. Under the "Wallet Details" tab, enter your private key in hexadecimal and click "View Details", and it will convert your key to WIF (near the bottom left, 51 characters starting with "5"). You should then be able to import this to the wallet of your choice.

Already download for version 1.14 or last version 1.19, The extract is went well.
But I cant use the command VanitySearch.exe  (Application Type)

Trying it look up about inside the file, seems like I didn't found.

How about notice command come? " is not recognized as an internal or external command, "

Anyone?

You got that error because the command entered isn't available, in your case, you're trying to run vanitysearch while there's no such executable in the directory used by the command prompt.
You should start command prompt where vanitysearch.exe is located or specify the path by following step 4 in the OP.

To be sure what caused the error, what is the exact command that you've entered?

Yes It's quite confused, that's why I'm search on inside folder.
There no such applications type for executed https://prnt.sc/10vqbjv 

I see, you've downloaded the source code and extracted it, not the .exe
What you need to download is the executable file from the releases, name: VanitySearch.exe, link in the OP step 1.

Tried with download file VanitySearch.exe then make it one on Files on extracted still not working.

You don't need the extracted files, just paste the vanitysearch.exe to any folder of your choice and follow the instructions in the first post/first page post 1.

Yes, I mean to copying file "vanitysearch.exe" to folder. sadly not working for me, https://prnt.sc/10vsgk4

What do you mean "not working"? It's in there the one you marked, if you're looking for the '.exe' extension, it's not displayed by default.
You can display known extensions by changing Windows Explorer's settings: Click "View" and put a check in "File name extensions".

By the way, you can delete all of the other files except vanitysearch.exe, you don't need them unless you're planning to compile it yourself.

Since this is a very beneficial guide but since the original post author has gone for years and imgur links are invalid on this forum, I decided to download those images, upload on talkimg.com and edit the quoted post with new image links to make everything smooth.
So, here we go:

Hello, I'm not very skilled in-depth about a program.

How do wedetect or identify that the application is safe?, Because this is a quite sensitive and high-risk.

If I'm download version 1.14 and last version 1.19. does we only can't able access about new feature right?

Does update also talking about being safety?
