Hm. Maybe weak conection? Try to use your private keys in other wallet (for example in bither).

Hi there! Using this service too and see today - my balance is 0.00. Blockchain shown real amount. What's problem?

This wallet is easy and secure. Strongly recommended

Question: Bitcoin Core allows addmultisigaddress nrequired ["key",...] ... where each key is a Bitcoin address or hex-encoded public key.

What's the difference or concern or problem or whatever reason for using a Bitcoin address and the hex-encoded public key?

I'll take a guess: you can't add using the Bitcoin address if you don't already have the private key in your wallet?

@OutCast3k
Will you also add the support for CSV?

Yes. Thanks for telling me that.

Now it's correct.

Cheers!

Edit: You missed typed the full URL https://ttutdxh-nubits.github.io/cointoolkit

But thanks for putting me on the right track

Bitcoin Testnet version does not seem to work, it's not recognizing my pub keys when i submit them to create a multisig address.

This forked version implemented it:

https://ttutdxh-nubits.github.io/cointoolkit

Is there a testnet version available somewhere ?

@OutCast3k
Can you add an easy way to cut the fee from the sending amount, instead of the local balance.

If I send 0.1 BTC to someone with 0.00001 fee, and he asks a faster transaction, I should be able to easily change the sending amount, example: 0.0999 BTC and 0.0001 fee.

He is the one that need a faster tx, not me, so he is he one that need to pay for it.

To add a 2-of-3 MustiSig address to bitcoin core you will need to execute in client console the following command (in your example):


Result:


In order to spend the funds from the MultiSig address you will need to import 2 of 3 private keys that correspond to these public keys:

Mr. OutCast3k,

I have a question, but it is more of a general question that is just indirectly related to coinb.in.

Can I add a multisignature address to bitcoin core? Can I then add the private keys (assuming I have them of course) and do a spend using that wallet?

For example, I create a 2-of-3 address. Let's make a more concrete example and I'll use your page to do it:

I first generate 3 regular addresses, public keys, and private keys:

KxbsQxm5Q8pGXPs8AWP7Lt1SkzFrvgZr2EdKpB9WTFCkC4cdnK3V

Then I input the above public keys in that order (and order seems to affect the result) and come up with the following:

Does bitcoin core (currently version 0.12.1) not work if I import the 3 private keys? Or it won't know what to do? That then leaves me with the option of using your site.

Actually, I'm looking for a way to do this with thousands of addresses (all of them multi-sig). The big wallet guys and exchanges have already done this, but I don't know if their code is open (I haven't checked.) Ideally, there would be 2 or 3 different physical machines with 2 cold offline airgapped, but for testing purposes it will be just one.

Great feature!

Replace by fee (RBF) has been added to coinb.in you can find it under the advanced tab, on the new transaction page.

Enjoy people!

You can try http://coinig.com which is a web based service.

Why can't i set custom transaction fees when creating  a transaction?
Why can't i spend just small amount from input? Not all of it?

Thanks that is very useful.

That's a very comprehensive link. Since starsoccer9 mentioned Brainwallet, I'll post this which was lightly modified from the brainwallet code.

https://github.com/ReinProject/bitcoin-signature-tool and see it in action at http://reinproject.org/bitcoin-signature-tool/

Maybe the tools presented here may be of some use:

I would love to see message signing and verifying added. Since brainwallet shut down, there really is no good web tool to use
