How to Recover Wanchain Sent to Ethereum Address!

About a month ago I accidentally sent all my Wanchain from an exchange to my Etherum address! I was in distress and this seems to be a common concern for many people.
But today I did it! I finally recovered all my Wanchain! It was not easy. I am a software engineer and it took a lot of my knowledge and a handy web tool to get them back. So without further ado here are the exact steps to recover your Wanchain:
Part 1 - Get your Ethereum Keystore File
*You can skip part 1 if you already have your Ethereum Keystore File
From My MetaMask Option
*If you use a MetaMask you must follow these steps AND the "From Private Key Option" steps below
  1. Click on the MetaMask on the top-right of Chrome
  2. Type in password to unlock
  3. Click on the 3 dots next to your account's name
  4. Click export private key
  5. Type in your password again
  6. Click submit
  7. Copy your private key
From Mnemonic (TrezoLeger users do this first!) Option
*If you use a TrezoLedgeHardware Wallet you will need to follow these steps AND the "From Private Key Option" steps below
  1. It is HIGHLY recommended that you transfer ALL other funds from ALL other cryptos off of your hardware wallet before following these steps.
  2. Download the Bip39 tool here: https://github.com/iancoleman/bip39/archive/master.zip (alternatively you can just go here, but it's less secure: https://iancoleman.io/bip39/)
  3. Unzip all the files
  4. Run bip39-standalone.html from the unzipped folder
  5. Type your 12-24 word Mnemonic given to you when you setup your Hardware Wallet into the BIP 39 Mnemonic input (If you don't have this you cannot recover your Wanchain)
  6. If you setup a passphrase for your Hardware Wallet (not your PIN code but an actual password) type it into BIP 39 Passphrase (optional) input. (If you don't have this and set one up originally with your hardware wallet you cannot recover your Wanchain)
  7. Change the "Coin" drop-down menu to Ethereum
  8. Scroll to the very bottom of the page and you should now see your Ethereum public key and private key for your specific Ethereum address that you accidentally sent your Wanchain to under "Derived Addresses". *If you do NOT see your address here then you did NOT follow the steps correctly
  9. Copy the private key on the right-hand side for your specific Etherem address that you accidentally sent your Wanchain to. This is under "Derived Addresses" Do NOT use any other private key on the page.
From Private Key Option
*These steps are outlined for Windows
(This part of the guide was found using part of this guide: https://ethereum.stackexchange.com/questions/110/how-to-mine-ether-and-use-ethereum-on-windows and part of this guide https://ethereum.stackexchange.com/questions/465/how-to-import-a-plain-private-key-into-geth-or-mist)
  1. Download Geth from here: https://geth.ethereum.org/downloads/
  2. Unzip Geth to C:\Geth (or any directory you will remember)
  3. Search for cmd (on Windows), Right-Click, Run As Administrator
  4. Open Notepad
  5. Paste your Ethereum private key into the notepad without any extra characters or quotations.
  6. Make sure you don't have a "0x" at the beginning of the private key. If you do, delete the "0x" off the start of the private key and save the file.
  7. Save the file as nothing_special_delete_me.txt at C:\Geth
  8. Open a command prompt (windows)
  9. Run the command: cd c:\Geth
  10. Run the command: geth account import C:\Geth\nothing_special_delete_me.txt
  11. After successful import, delete the file at C:\Geth\nothing_special_delete_me.txt
  12. Your file will be saved at, replace "UserName" with your computer's actual logged in user name: C:\Users\UserName\AppData\Roaming\Ethereum\keystore
Part 2 - Recovering Your Wanchain
And now what you've been waiting for. Follow these steps to recover your Wanchain from your Ethereum Keystore File.
Part 2A - Setup a Wanchain Wallet with WanWalletGui
*If you already have a Wanchain wallet setup and know your public key, private key, and password for that wallet you can skip Part 2A
We need somewhere to send the Wanchain when we recover it. Follow these steps to setup an address to use on the Wanchain network. You cannot keep using the Ethereum address you sent your Wanchain to on accident after recovery. Just bear with me.
  1. Download WanWalletGui from here: https://wanchain.org/product
  2. Click on the logo of your operating system to download the WanWalletGui
  3. Accept the User Agreement
  4. Unzip all the files
  5. Run WanWalletGui.exe
  6. Click Launch Application from the pop-up
  7. Click the "Account" button on the top-right
  8. Type in any account name you want and your new password twice
  9. Click "OK"
  10. Save the "Public Key" displayed for your account somewhere
  11. Close the program. Make sure to actually close the program as it will interfere later on.
Part 2B - Get the Gwan Tool Up and Running
This is Wanchain's version of Geth, it's called Gwan (get it, G"Wanchain"). You will need this to submit the recovery transaction since the WanWalletGui.exe can't submit it for us.
  1. Download the Gwan tool from Wanchain's Github via the zipped archive. The latest release at the time of writing is 1.0.4. You can download from this link: https://github.com/wanchain/go-wanchain/releases/download/v1.0.4/gwan-windows-amd64-1.0.4-b7ce29ea.zip
  2. Unzip the Gwan.exe file from the zip
  3. Open a command prompt (or equivalent if not on Windows)
  4. Go to the directory that you unzipped Gwan to (cd command on Windows)
  5. Run this command: gwan --rpc --rpcapi=web3,eth,personal --rpcport "8545" --rpcaddr "" --rpccorsdomain ""
  6. Leave the command prompt up and running until all remaining steps in all parts are finished. If you close the command prompt you cannot submit the recovery transaction. This is actively listening on your computer.
Part 2C - Install Node
*If you already have Node.Js & NPM installed AND updated you can skip Part 2C
  1. Download Node here for the right OS/bit version: https://nodejs.org/en/download/
  2. Run the installer (On Windows it's a .msi file)
  3. Go through the install process using the defaults and click finish
Part 2D - Use the Wanchain-Raw-Tx tool to submit your recovery transaction
This is it! The final part! You're soo close if you made it this far!
  1. Download the Wanchain-Raw-Tx zip directory here: https://github.com/ssc806/wanchain-raw-tx/archive/master.zip
  2. Unzip all the files
  3. Open another command prompt (or equivalent) and go to the unzipped directory
  4. Type this command: npm install
  5. You may get ERR's in red. That's fine, ignore them.
  6. After the prior command completes leave the command prompt open and also open "config.js". Make all changes to the file after each line's colon. Leave quotes when you see them around the examples. You will need to edit the config.js file as follows:
  7. Change the first line to: datadir : '/'
  8. Change fromAddr to the Ethereum address you accidentally sent your wanchain to
  9. Change the passphrase to the password you setup for your Ethereum Keystore File
  10. Change the chainId to 0x01 (no quotes)
  11. Change the toAddr to the new Wanchain address you setup in "Part 2A"
  12. Change the sendAmount to be the amount of wanchain you want to transfer and then leave the * 1e18 at the end so 50 Wanchain = 50 * 1e18 (no quotes or spaces). Make sure to not transfer everything, leave .01 Wanchain for the transfer fee.
  13. Save the file, it should now look something like this:
    module.exports = { datadir : '/', // The datadir path of the Ethereum fromAddr : '0xaaa', // Ethereum address which hold the Wancoin passphrase : 'password', // The passphrase for the Ethereum keystore of the above address chainId : 0x01, // 0x01 - Wanchain Mainnet, 0x03 - Wanchain Testnet toAddr : '0xbbb', // Wanchain address, make sure have the correct Wanchain keystore for this address sendAmount : 1000*1e18, // 1000 Wan. Don't send all the wancoin, need to keep about 0.005 Wan as the tx fee gasPrice : 200*1e9, // 200 GWin gasLimit : 47000 } 
  14. Open your C:\ (or main directory)
  15. Create a folder, name it "keystore"
  16. Copy and paste your Ethereum Keystore File into this directory. You must put it in this EXACT location.
  17. Go back to your command prompt that you last used to do the command "npm install"
  18. Type this command: node index.js (if that doesn't work try: node index)
  19. If all went well you should now see your TxHash of the completed transaction.
  20. Wait 5-10 minutes
  21. Close the command prompt running Gwan
  22. Open WanWalletGui.exe
  23. Your funds should now be displayed there!!
If this helped you please consider sending some WAN to: 0xC0dF0c37966488941765f5659ff552aA4e0595B5

Call for action: What can I do to help Ethereum Classic project?

So, you've looked through our web site, understand the value proposition of open, neutral and immutable blockchains. You would like to help original Ethereum vision to succeed. What can you do? Here are some ideas:
Get a Classic wallet
Create new Ethereum Classic wallet in few easy steps. Running a web-based Classic wallet is also possible: http://classicetherwallet.com/
Run a Classic node
We need better network bootstrapping. Run a dedicated Classic node. If your node maintains good uptime and network connectivity, please notify the developers so they can add them to bootstrap list. Also, please consider adding your node to network status monitor (Netstat): http://etcstats.net/
Help with community tools
There is a community-driven effort to create ethereumclassic.com website. If you are interested to participate, please join the discussion.
Another initiative is to create Ethereum Classic Guide and improve overall quality of documentation. ETC should be accessible to anyone, and easy to start with!
Ethereum Classic wiki needs some love as well. Please share your knowledge and help others get going with Classic.
Contribute to development
If you have skills, please consider joining our dev team. We are working actively on geth/mist/etherwallet, but we need developers to begin migrating/restoring other clients and key supporting sw.
Alternatively, you can help improve community tools. Block explorer improvement is our top priority right now. Beta support for exploring addresses and transactions appeared, but more is needed. Block explorers are essential, and before Classic there were no open source ones in Ethereum ecosystem.
Mine the original chain
Start mining to support network and earn classic ethers (ETC). Difficulty is relatively low, so even solo miners have a decent chance to find a classic block or two. Here is some info on solo mining, ETC mining guides and tips. Join in on the fun!
There are many Classic pools now, some of them listed on a sidebar (to the right). New pools, please list yourself on ETC Wiki.
The pools are run independently of Ethereum Classic project, so do your own due diligence. BTW, why don't you start running your own Classic pool? Here is some opensource code, if you are interested.
Trade ETC for fun and profit
Trading classic ethers (ETC) is important as it gives our chain tokens value, attracting more miners.
ETC trading is now live on all the major crypto-exchanges. Bitfinex, Poloniex, Kraken offer trading pairs such as ETC/BTC, ETC/USD and ETC/ETH. Complete exchange list in the sidebar (to the right). Please trade ETC if you are interested in active market forming or want to increase your stake in the success of Ethereum Classic.
Spread the word
Please help us spread the word about Ethereum Classic around Ethereum community and beyond! You can use this logo set, or create something better still. Start websites. Write blog posts. Tweet. Let people know about Ethereum Classic and its value proposition.
Feeling like something needs to be done, and no one is doing it? Take the initiative! Ask around our Slack channel if there is something urgent to be done.
Thanks for your support, and let's move our chain along! Stay classy, everyone! ;)

Hard fork went smoothly, Ethereum Classic chain is alive and kicking!

News update
Ethereum Classic is starting to make some serious waves. With a surprise announcement of ETC trading on Poloniex, it immediately became trader's favorite. ETC/BTC is now the most active pair on Poloniex, with daily trading volume exceeding 100K BTC. Chinese exchange Yunbi announced start of ETC trading tomorrow. Coinmarketcap added ETC to its coin lineup, where it currently fighting with Litecoin for #5 position, with a market cap exceeding $150 mln. Miners who support Classic are able to make good money now: turns out, Classic mining is the most profitable of all coins. New pools offered ETC mining support. Nethash increased significantly to about 500+GH.
Classic pools:
New pools, please list yourself on ETC Wiki.
More info on solo mining and more mining tips.
The pools listed above are run independently of Ethereum Classic project, so do your own due diligence. BTW, why don't you start running your own Classic pool? Here is some opensource code, if you are interested.
Community tools
You can use (beta) block explorers to follow the chain progress:
Slack channels always have lively discussions: https://ethereumclassic.herokuapp.com/
Our newest addition: Ethereum Classic wiki. Please share your knowledge and help others get going with Classic.
Trade classic ethers (ETC) on Poloniex and BitSquare. Please engage in ETC trading if you are interested in active market and want to increase your stake in Ethereum Classic.
Please help us spread the word about Ethereum Classic around Ethereum community and beyond! Use this logo set or create something better still. Start websites. Write blog posts. Tweet. Let people know about Ethereum Classic and its value proposition.
Thanks for your support, and let's move our chain along! Stay classy, everyone! ;)
