1. Instruction for an ETH-wallet creating and Playkey ICO participating

1.1. Create Ethereum-wallet

In order to participate in the Playkey ICO, you must have an Ethereum-wallet. If you do not have such wallet, we recommend creating it using the MyEtherWallet service.

If you have an existing MyEtherWallet account, please jump to the next section «View the Ethereum-wallet info».

Please note that cryptocurrency exchange account is not suitable for purchasing PKT. You need to have a full Ethereum/Bitcoin wallet, not a trading account.

1.1.1 Go to the MyEtherWallet website

Go to the MyEtherWallet website: https://www.myetherwallet.com/. Make sure that you access the website via an HTTPS protocol:

1.1.2 Enter a password

On the “New Wallet" tab, enter the password that will be used to access your wallet (create a strong password using uppercase and lowercase letters, numbers and symbols).

4

Click on the “Create New Wallet” button.

Do not forget this password! If you lose your password, you will lose all ETH and PKT stored in your account.

1.1.3 Download Keystore file

Click on the “Download Keystore File” button.

The file will be downloaded to your computer.

This is a digital signature file for your wallet. 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. If you lose one of them, you will lose all ETH and PKT stored in your account.

5

1.1.4 Backup your private key

Click on the “I understand. Continue” button.

Click on the “Print Paper Wallet” button.

Save or print the data file:

Do not share your private keys with anyone. The private key is an analog of the PIN code from your bank card. If anyone obtains your private key, they will have access to all of your funds.

6

1.1.5 Open your wallet to view the address

Click on the “Save Your Address” button.

Select the “Keystore File (UTC / JSON)” item.

Click on the “SELECT WALLET FILE” button and select the keystore

file downloaded in section 1.1.3.

Enter the password.

Click on the “Unlock” button.

At the bottom you will see your wallet info:

"Account Address" fields:

1.3. Buy ETH

Only the ETH cryptocurrency will be accepted on the PKT sale. You can buy ETH for any fiat currencies (e.g., USD, rubles, etc.) on any cryptoexchange (e.g., Coinbase.com, Kraken.com, poloniex.com, Cex.io). Also you can buy ETH for other cryptocurrencies (e.g., BTC, Dash, etc.) using exchange services.

The easiest way to buy ETH is to buy for USD using an exchange service. We recommend using the BestChange service.

Go to https://www.bestchange.com

In the “Give” column select the payment method, e.g. “Visa/MasterCard USD”.

In the “Get” column select “Ethereum (ETH)”.

Select the exchanger with the best rate and go to it.

Follow the instructions of the selected exchanger and refill your ETH-wallet.

12

1.4. Send ETH to buy PKT tokens

Make sure that you have enough ETH in your wallet to make a transaction with a small fee for a transaction called "gas".

1.4.1 Go to https://playkey.io 30 minutes before the start of the PKT sale

The token sale will begin on November 1, 2017 at 08:00 GMT+3 and will end on November 30, 2017 at 23:59 GMT+3 or when the maximum sales level reaches 60,000,000 PKT.

We will publish the token sale address in 30 minutes before the start of the token sale in order to prevent fake addresses.

If you send ETH before the sale starts (November 1, 2017 at 08:00 GMT+3), your transaction will be rejected. The PKT sale will be carried out only on the site https://playkey.io.

1.4.2 Go to the MyEtherWallet website

Go to the MyEtherWallet website: https://www.myetherwallet.com/. Make sure that you access the website via an HTTPS protocol:

In the “Amount to Send” field, fill in the amount of ETH you wish to use to buy PKT tokens.

In the “Gas Limit” field, change the minimum amount to 200,000 gas. This will guarantee the processing of your transaction.

Click on the “Generate Transaction” button.

If a warning appears that the transaction will fail, click on the "Cancel" button:

14

Check all transaction parameters and make sure that the required number of tokens is available for sale (https://playkey.io will display this information). Then try again.

If no warnings appear, click on the “Send Transaction” button.

A pop-up appears in which you need to confirm the transaction. If the data is entered correctly, click on the «Yes, I am sure! Make transaction» button.

Do not click the button more than once!

Now you have purchased the amount of PKT that corresponds to the sent amount of ETH.

After sending the request, you receive a link to your transaction.

PKT tokens appear in the “Token Balances” section.

2. FAQ

2.1. Why can’t I see the account I have just created in the blockchain explorer (e.g., Etherscan)?

Only active accounts are visible in a blockchain explorer. Once you transfer ETH to your account, it should become visible.

2.2. Why can’t I see my balances when I open my wallet?

Most likely this is due to the firewall. In order to see the balance, you will need to use a blockchain explorer, for example, Etherscan.

2.3. I’m trying to unlock my wallet but it keeps hanging

Most likely this is due to decryption of Keystore-files.

In this case we recommend:

Use the Google Chrome browser.

Close other programs (e.g., a lot of browser tabs, etc.).

Click "Continue" when a pop-up with an error indicating that the service is not responding appears.

2.4. Transaction Failed – "Out of Gas"

Service MyEtherWallet automatically estimates the amount of gas that is required to make a transaction, but sometimes this estimate is incorrect.

Try manually increasing the “Gas Limit”. For example, try doubling the amount of gas that MyEtherWallet estimates, and sending again (any excess gas will be returned to you).
