Introduction
Created by kvhnuke & tayvano, MyEtherWallet is a free, open-source, client-side
tool for securely interacting with the Ethereum network.
While the following instructions will guide you through the setup of an
MyEtherWallet with token support, all participants should also conduct their own
research on the setup process.
We make no representations or warranties that the following material is complete
or accurate, or that the MyEtherWallet (or any associated software or services)
will be reliable or function as described. As such, participants assume all risks
associated with the use of MyEtherWallet (or any other ERC20 wallet) in
connection with the token sale.
For the terms and conditions concerning the CLN token sale please visit cln.colu.com
We have provided an FAQ at the end of this document. However, if you should have

Create New Account
If you have an existing Ethereum account you can use via MyEtherWallet, please skip
this section and jump ahead to the next section, “Using Existing Account.”
Step 1: Go to https://www.myetherwallet.com/
Make sure that you are on a computer you trust and that you access the website via
an HTTPS address. If you’re using Chrome, you should see a lock notification in the
address bar.
Step 2: Go to the “New Wallet” Tab
Step 3: Provide a Strong Password
Provide a password that will be used to access your wallet:
1. Create a strong password, using upper and lower-case letters, and also numbers
and symbols (e.g., “@”, “^”, etc.).
2. Do not lose this password. Losing this password is equivalent to losing all of the
ETH and CLN stored in your account.
Click on the “Create New Wallet” button.

Step 4: Save Your Keystore File
Follow the instructions to save your keystore file. This file contains your private and
public keys and is required every time you want to access your account.
Please note that you won’t be able to access your account without this file and the
password from the previous step. Losing either one of them is equivalent to losing all
of the ETH and CLN stored in your account.
Step 5 (optional): Backup Your Private Key
If you would like to make this account accessible by other Ethereum wallets, you
can export and backup your private key.
It is important to remember that you should never share your private keys with
anyone else. If your wallet address (i.e., your public key) is the equivalent of your
bank account number, then your private wallet key is your PIN. If anyone obtains
your private key, they will have access to all of your funds.
Step 6: Unlock Your Wallet to View the Public Address
Follow the instructions to unlock your wallet and get your public address:
Select the “Keystore File (UTC / JSON)” and the keystore file you’ve downloaded
in the previous step:

them in the token sale event.

Sending ETH to the Token Sale Address and Buying CLN
Make sure that you have enough ETH in your wallet to cover your participation as
well as a small transaction fee on the Ethereum blockchain, known as “gas”.
Step 1: Go to https://cln.colu.com/ 24 Hours Before the Start of the
Token Sale
The token sale is scheduled to start in January 2018 and will last 7 days or until the
hard cap is reached. We will publish the token sale address at least 24 hours before
the start of the token sale in order to help you prepare.
Make sure the sale has started before you send ETH. If you send ETH before the
sale starts, your transaction will be rejected.
The address of the sale will be published only on https://cln.colu.com.
DON'T USE ANY OTHER ADDRESS TAKEN FROM ANY OTHER SITE OR ANY
MEANS OF COMMUNICATION.
Step 2: Go to https://www.myetherwallet.com/
Go to the MyEtherWallet website at https://www.myetherwallet.com. Make sure
that you are on a computer you trust and that you access the website via an
HTTPS address. If you’re using Chrome, you should see a green lock notification in
the address bar.
Step 3: Go to the “Send Ether & Tokens” Tab
Choose how you would like to access your wallet. For instance, if you choose to
access using your keystore file, select the wallet file as indicated above, insert your
password and click “Unlock” to proceed.

Step 4: Send ETH to the Token Sale Address
You will then be asked to fill the “Send Transaction” form.
• In the “To Address” field, paste the sale address copied in the last step.
• In the “Amount to Send” field, fill in the amount of ETH you wish to use to buy
CLN tokens
• Select the Gas Limit (transaction fee). If you see a gas estimation of -1, it means
that the transaction will not be executed. This could happen because of several
things such as sending before / after the sale, or sending from an unauthorized
address. If the gas estimation is 120,000 please check that the TO Address is
the CLN official sale address
• Click on “Generate Transaction.”
A popup will appear. Click “Send Transaction.” MyEtherWallet will ask you to confirm
the transaction. If the data is correct and you wish to proceed, click “Yes, I am sure!
Make transaction.”
DO NOT click on this button more than once.

Congratulations! You have now purchased the amount of CLN that corresponds to
the amount of ETH you sent.
After sending the request, you should get a link to your transaction (powered by
the etherscan.io web service).
Step 5 (optional): Confirm Your ETH Were Sent
Open your transaction in etherscan.io, by clicking on the “Verify Transaction.”
You should first see the transaction as pending.
After a few moments (depending on the performance of the Ethereum network), you’ll
see the transaction as submitted, and a few moments later you will see a confirmation:

Acquiring Ether (ETH)
Ether (ETH) will be the only acceptable form of payment in the CLN token sale.
Please make sure that you have adequate ETH available for the token sale.
You can purchase ETH with fiat currencies such as USD, Euro, etc., on any of the
well-known cryptocurrency exchanges, such as:
• Coinbase.com
• Cex.io
• Kraken.com
• poloniex.com
You can also exchange existing cryptocurrencies (e.g., BTC, Zcash, Ripple) for ETH
using an exchange service such as:
• Shapeshift.io
• changelly.com
During the token sale event, please ensure that the amount of ETH you have
in your wallet is sufficient to cover your buy-in amount as well as the fee for
transacting on the Ethereum blockchain (i.e., “gas”). Before the token sale starts,
we will publish recommendations on the amount of gas needed to participate.
Any attempts to send ETH from a different address or directly from an exchange
(e.g., Coinbase, Kraken, Poloniex, etc.) during the sale will result in an inability to
purchase CLN and your ETH may be permanently lost.

Frequently Asked QuestionsFor more info, please visit the official: MyEtherWallet's FAQ.
Why can’t I see my balances when I unlock my wallet? This is most likely due to the fact that you are behind a firewall. It is common for
the API that is used to display the balance to be blocked by firewalls. You will still
be able to send transactions, but you will need to use a blockchain explorer, such
as Etherscan, to view your balance.
Why can’t I see the account I have just created in the blockchain explorer (e.g., Etherchain, Etherscan)? Only active accounts are visible in a blockchain explorer. Once you have
transferred some ETH into the account, it should be visible.
How does MyEtherWallet actually work? Please check this page: https://myetherwallet.groovehq.com/knowledge_base/
topics/how-doesmyetherwallet-actually-work
Why am I seeing two different versions of my Ethereum address - one with uppercase letters and one with lowercase letters? Capitalization simply means the address has a checksum, which will detect input
errors. Both addresses refer to the same wallet and are fully functional.
For example, two versions of an Ethereum address are below.
• 0x0430894efd64349c078877E42F1c7c7B838cf108
• 0x0430894efd64349c078877e42f1c7c7b838cf108
The address containing lowercase letters is not checksummed. Mistyping a letter or
number in this address can result in the loss of ETH. On the other hand, the upper
case checksummed version of the address will detect typos and inform you of an
invalid address.
For this reason, MyEtherWallet warns you when your address is not checksummed.
Remember to double check the address to prevent any issues.
If you are sending ETH to one of your own wallets, you can save the checksummed
address via the "View Wallet Info" page and copy the address displayed there.

I am trying to unlock my wallet but it keeps freezing / hanging Sorry you are having trouble. Decrypting the keystore files is an intensive process
and takes longer in Javascript. We recommend:
1. Using Google Chrome.
2. Clicking "Continue" when you see the unresponsive error alert pop up.
3. Closing other intensive programs open (e.g., browser tabs, video games, etc.).
The combination of the above typically eliminates the problem. If it doesn't, please
contact us and include your browser and OS and we can advise from there.
