Bitcoin Cash / Bitcoin Satoshi Vision coin splitter.

Note

This project is out of date, but I'm keeping it up for posterity. The best way to split your coins nowadays is to get some already-split dust and use the official Electron Cash (on BCH) and/or ElectrumSV (on BSV). New users should avoid using this version due to phishing vulnerabilities in Electron Cash that have appeared in the last few months. Cheers! -Mark

CHECKDATASIG/MUL Coin splitter

Licence: MIT Licence
Author: Mark B. Lundeberg
Language: Python

This is a special release of Electron Cash augmented with a coin-splitting tool for the November 2018 Bitcoin Cash hard fork. The tool can be started via:

• Tools menu | Coin splitter, or,
• Addresses tab: right-click on an address | Split coins.

By using this tool, you can create transactions built on a history involving the new OP_CHECKDATASIGVERIFY. Such transactions are impossible to replay on other nodes / chains that do not support this opcode. In a secondary mode, you can also create OP_MUL-based splitting, though with some limitations.

A detailed usage guide can be found here: doc/coinsplitter_user_guide.md (中文版请访问这个链接：doc/CoinSplitterUserGuide_CN.md)

Since Electron Cash 3.3.3, the mainline client has been checkpointed so as to only connect to BCH servers. In contrast, this release is being maintained up-to-date but with the checkpointing reverted, and with a healthy list of BSV servers included, so you can connect to both BCH and BSV. Enjoy!

For the technically inclined / curious, the primary code additions appear in this file and this file.

Standard instructions for Electron Cash (the base software) follow:

Electron Cash - Lightweight Bitcoin Cash client

Licence: MIT Licence
Author: Jonald Fyookball
Language: Python
Homepage: https://electroncash.org/

Getting started

Electron Cash is a pure python application forked from Electrum. If you want to use the Qt interface, install the Qt dependencies:

sudo apt-get install python3-pyqt5

If you downloaded the official package (tar.gz), you can run Electron Cash from its root directory (called Electrum), without installing it on your system; all the python dependencies are included in the 'packages' directory. To run Electron Cash from its root directory, just do:

./electron-cash

You can also install Electron Cash on your system, by running this command:

sudo apt-get install python3-setuptools
python3 setup.py install

This will download and install the Python dependencies used by Electron Cash, instead of using the 'packages' directory.

If you cloned the git repository, you need to compile extra files before you can run Electron Cash. Read the next section, "Development Version".

Development version

Check out the code from Github:

git clone https://github.com/Electron-Cash/Electron-Cash
cd Electron-Cash

Run install (this should install dependencies):

python3 setup.py install

Compile the icons file for Qt:

sudo apt-get install pyqt5-dev-tools
pyrcc5 icons.qrc -o gui/qt/icons_rc.py

Compile the protobuf description file:

sudo apt-get install protobuf-compiler
protoc --proto_path=lib/ --python_out=lib/ lib/paymentrequest.proto

Create translations (optional):

sudo apt-get install python-requests gettext
./contrib/make_locale

For plugin development, see the plugin documentation.

Running unit tests:

pip install tox
tox

Tox will take care of building a faux installation environment, and ensure that the mapped import paths work correctly.

Creating Binaries

To create binaries, create the 'packages/' directory:

./contrib/make_packages

This directory contains the python dependencies used by Electron Cash.

The make_packages command may fail with some Ubuntu-packaged versions of pip ("can't combine user with prefix."). To solve this, it is necessary to upgrade your pip to the official version:

pip install pip --user

Linux (source with packages)

Run the following to create the release tarball under dist/:

./setup.py sdist

Mac OS X / macOS

See contrib/osx/.

Windows

See contrib/build-wine/.

Android

Issues with claiming BCH SV from Ledger Nano S

I had 2 Ledgers, the first splitting went fine.
With my second ledger, it didn't read all my transaction in the history. I had sent BCH on Nov 14 2018, 1 day prior to the split, I see the transaction ID on the blockchain but the Electrum Cash tool is not reading this transaction making my life hard to recuperate these coins.
It seems that is reading and old public key that has been emptied but not the new public key where the last batch of BCH where sent to.
Anyone had a similar issue? Appreciate any help I can get.
Tks

Bitcoin Cash SV

Hi!

I followed the steps in this tutorial to claim my Bitcoin Cash SV: https://support.ledgerwallet.com/hc/en-us/articles/360012270054?input_string=bitcoin+cash+sv

I didnt finish the step 7 because i didnt want to spend my BSV. But now I don't know if that step is obligatory to successfully claim my BSV.

I am sending a print from my screen to help me explain. So my question is: this amount that I have in my wallet is BSV already? Or should I follow some additional step to conclude my claim?

Thanks for your help, bye!

AttributeError when trying to split coins

I get stuck on step #2, when connecting my nano S, it gives me an error -- see attached file. "NoneType" object has no attribute "handler"

Thanks for programming bitcoin-splitter ...

Doesn't run on MacOS High Sierra

I am trying to run this on High Sierra, and can't get it to even start. When I click on the icon, I get a bobbing icon in my dock, and then it just quits.

Exception:invalid status 6b00

I did split BSV from BCH as https://support.ledger.com/hc/en-us/articles/360012270054-Safely-claim-Bitcoin-Cash-SV, but whenit comes to step7:send your BSV, my ledger wallet stops connection, so i close the electron cash and restart it, but when i send BSV in the electron cash, it did not work, showing 'Exception:invalid status 6b00'

Second send of coins sent did not broadcast, Any help?

Hi Mark,

I sent a small test of coins to Kraken from the ledger nano I had your coinsplitter attached. It worked perfectly once received in the Kranken exchange the coins were split, I felt comfortable to send all and then the BSV coins did not turn up in the 2nd transaction, below is what Kraken and Ledger support both said. I am at loss to know what to do. Could you offer any guidance, please?

Thank you for reaching out again,
Your funds are not lost, they are still on the sending address you can check it yourself on the BSV explorer,
This is the address for your convenience qq0qejgq33n7d38xtjnmyy0wpyp50j5r9sr8dtwu7k.
We split the coins when they are included on the transaction just like the first deposit.
as I said before your wallet either didn't broadcast it to the BSV chain or that the transaction wasn't replay-able. If it is replay-able you will need to find a tool to broadcast the transaction on or alternatively import your keys into a BSV wallet and send the tokens manually.
The BSV funds are still resting on the sending address.

Question regarding OP_MUL and if I did all this right =)

I just want to make sure I did this right.
Using the hardware/offline wallet method I did the following:
For CDS - ensured electron was on CDS network then followed all steps using CDS split method for the 1000 satoshi tx from offline / hardware wallet -> electron contract address -> output back to offline/ hardware wallet address -> created new tx on offline / hardware that spent entire wallets balance including the tiny contract address to a different address in wallet.
Everything confirmed, have over 100 confirmations on the above.

After the above, I then did the same thing with electron pointed at the non CDS network then used the split MUL tool on that network ... everything confirmed.

So, I should have non replayable coins on each chain now correct?

import existing seed phrase fail, and confirm new seed phrase fail

When importing a seed phrase from another wallet it won't allow you to click the "Next" button, and when confirming a new seed phrase it won't let you click the "Next" button.

I don't see my second BCH account from Ledger Nano S in Electron Cash

Hi! Thank you for the tool. It worked fine for my first account. But as you probably know, Ledger let's you create multiple accounts with their addresses under the same Master account. So I have 2 accounts with BCH. And I don't see my second BCH account in Electron Cash. I just see there and can work with the coins from the first account only. The second account and its addresses seem to be missing. Do I have to turn it on somehow, or switch to?

Following the instructions from the Ledger site
https://support.ledgerwallet.com/hc/en-us/articles/360012270054-Safely-claim-Bitcoin-Cash-SV

I get stuck on step 4, see attached image for error message once I hit "broadcast"

Any ideas where I'm going wrong or what the problem is?
