The token swap procedure is simple to execute in just a few steps, and will only take a few minutes. To get started, you will need to be able to access the wallet that holds your SPRK tokens via MyEtherWallet, and a small amount of ETH in that wallet.

If you have a MetaMask wallet, we recommend our simpler token swap instructions for [MetaMask](https://steemit.com/sparkster/@sparkster/sprk-token-swap-procedure-for-metamask). The new tokens will be locked until September 2nd 2019 to allow everyone sufficient time to swap tokens.

<b>Step 1:</b> First calculate the <i>‘Wei’</i> quantity of the number of tokens you wish to swap. To do this, navigate to https://etherconverter.online. In the <i>‘Ether’</i> field, type in the number of tokens you wish to swap.

For example, if you wish to swap 100 SPRK tokens, you would type in 100 in the <i>‘Ether’</i> field. Copy and paste the <i>‘Wei’</i> value that is generated into a document. You will need this quantity in a Step 4.

<b>Step 2:</b> Once you’re logged into MyEtherWallet, click on <i>‘Contract’</i> in the left hand menu, then click on <i>‘Interact with Contract’.</i>

In the <i>‘Contract Address’</i> field, paste: 0x971d048e737619884f2df75e31c7eb6412392328

In the ‘ABI/JSON Interface’ box paste:

    [{"constant":false,"inputs":[{"name":"_spender","type":"address"},{"name":"_addedValue","type":"uint256"}],"name":"increaseApproval","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"}]
<br>
Then click <i>‘Continue.’</i>

<b>Step 3:</b> From the <i>‘Select an item’</i> dropdown, select <i>‘increaseApproval.’</i>

In the <i>‘_spender (address)’</i> field insert the new contract address: ‘ 0x80a740C8FFa28C8C2c3f1fc8b6c1A0A442212E71’.

In the <i>‘_addedValue (uint256)’</i> field insert the Wei quantity of tokens from Step 1. In this example, 100 SPRK tokens, that is 100000000000000000000.

Leave <i>‘Value in ETH’</i> at 0 as you are not transferring any value.

Then click <i>‘Write’</i>

<b>Step 4:</b> Follow the steps you would typically follow for a payment transaction to complete the transaction. We have not provided the specific steps as they vary by the type of wallet you have. For example, the steps for a hardware wallet are different to the steps for a software wallet. You should be familiar with these steps if you have used MEW to transfer funds between wallets.

<b>Step 5:</b> Once your transaction has been confirmed on the Ethereum network, go back to MyEtherWallet, in the menu click on <i>‘Contract’</i> and <i>‘Interact with Contract’</i> again.

In the <i>‘Contract Address’</i> field, paste: 0x80a740C8FFa28C8C2c3f1fc8b6c1A0A442212E71

In the ‘ABI / JSON Interface’ box paste:

    [{"constant":false,"inputs":[],"name":"swapTokens","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"}]
<br>

Then click ‘Continue.’

<b>Step 6:</b> From the <i>‘Select an item’</i> dropdown, select <i>‘swapTokens.’</i>

Leave <i>‘Value in ETH’</i> at 0 as you are not transferring any value.

Then click <i>‘Write’</i>

<b>Step 7:</b> Follow the steps to complete the transaction, in the same way you would complete a payment transaction.

That’s it! Your tokens have been successfully swapped.
