5 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.

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.

6 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.

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.

10 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.
11 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.
12 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:
13 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.
14 Frequently Asked Questions For 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.
15 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. Where can I get more help?
