It's a multisignature address.

On bit-x.com or coinbase.com you can generate them.

[BiTJack]

It an Multi-signature address. You can read more on this wiki link & how to create one Here. There are many ways to create a multi sig address.

[Wusolini]

you can  generate addy with any required sign (even word) at beginning.

But more special signs you want the more you will pay for that.

If you have any GPU's around they speed up vanity address a whole lot.  There is a good site that sells them but I would rather make it myself personally.

It's simply a multi signature address. If I'm not wrong if you sign up in BIT-X you'll be able to create this type of address. Same thing is for Coinable.com.

OP was asking for the first letter itself. What you are saying is for the letters which come after it.

The one mentioned here is a multi sig address. Its useful to secure Bitcoins and should be more widely promoted.

[Amph]

core can't make multiaddress yet, if i'm not mistaken, you need an alternative way, online maybe

Unfortunately AFAIK none of the popular wallets can process multisig directly in GUI now. It could be much more widely used if it has been made easier to use.

You can use addmultisigaddress (FYR: https://bitcoin.org/en/developer-reference#addmultisigaddress) and createmultisig (FYR: https://bitcoin.org/en/developer-reference#createmultisig) in bitcoin core. But please make sure you understand these well enough and make thorough tests before using them on production.

[Gianluca95]

That's only a multi signature address which can be created thanks to BIT-X.com or Coinbase.com. If you create an address with this two type of exchange, you'll have an address which started with 3

Well, with bitcoin core you can and it's fairly easy but you need to know what you are doing there and how it'll work after it.
This is for creating a multisig of 2of2 .

1. { validateaddress "address" } Do it with both addresses and copy the "pubkey" it gives you.
2. { createmultisig 2 '["1st pubkey","2nd pubkey"]' }
3. Save the redeemScript.
4. Paste the same command in step-2 but replace "createmultisig" with "addmultisigaddress"

Hope it works.

Will I be able to spend the inputs in a multisig address directly in the Coin Control window, or will I need to use "createrawtransaction"?

createrawtransaction '[{txid":"*","vout":*,"scriptPubKey":"*","redeemScript":"*"}]'
'{"btcaddress":amount}'

You can, but its not from GUI, you have to use console. Multisig should be made an obvious feature instead of making it difficult to use.

I know coinbase allowed, and they are saying bitx does too, which is a welcome feature. Far too often security is not prioritised.

Didn't even know that was possible, great information

You have to generate many many address and then find what you want.

[yenzae0215]

its my first time seeing BTC addy that doesnt start with 1.. LMAO (newbie here)

[SirChiko]

but you can generate your first numbers/letters with vanity also.

[sifter]

Is it possible to generate a multi-wallet vanity address?

Like the first number being 4 and the next few letters a word.
