Qtum Swap October 4

The swap from ERC-20 tokens to Qtum’s functional network tokens will take place on October 4th, 2017.

The participating exchanges will be ChBTC, Bittrex, AllCoin, BTer, Coinnest, and Coinone.

https://www.coinnest.co.kr/ was recently added to this list, after many people in the Korean community requested it. Thank you for your input, we value it greatly.

For Binance, please see:

Keep in mind that the only way you can swap Qtum ERC20 Tokens to Qtum Ignition Main Network is by following this guide, if you see any information contrary to this guide, consider it as an attempt to steal your Qtum tokens.

If you miss the October 4th swap date, we have partnered with Changelly.com to catch anyone who missed this event. On October 9th, there will be a section on Changelly that allows you to deposit your ERC20 tokens, they will ask you to provide a Qtum Ignition deposit address (which you can get from downloading the wallet from our github)

Be advised that markets may be locked for deposits and withdrawals for 24–48 hours.

Here are the instructions, copied directly from our previous community updates:

https://medium.com/@Qtum/qtum-community-development-updates-september-18-31970934b7d3

“You must have your Qtum ERC20 tokens on a participating exchange before October 4th, 2017 for them to be swapped for Qtum Ignition tokens. We will ask exchanges to halt trading 24 hours prior to the swap. If you are not familiar with depositing tokens to an exchange, please orient yourself with this procedure. Always do a small test deposit before sending the entire contents of your wallet.

Once your Qtum ERC20 tokens have been converted to Qtum Ignition, you will need a wallet to withdraw. Please ensure that your computer is not infected with malware or viruses, and that you are using the correct wallet (not Sparknet or Skynet, you must download the Ignition wallet). Once the main network tokens are in your possession, you should encrypt your wallet, and back it up. Make multiple copies and make sure you use a strong password. If you lose or forget this password, your tokens will most likely be lost forever.

Please be weary of any other third parties and non-affiliated Qtum websites. We fully expect impostors to try and steal tokens from holders like yourself. Be advised that if you fall for one of these scams, or make an error with the swap, we will not reimburse you. There is no fund set aside for reimbursements.

For users with more than 100,000 Qtum tokens not willing to use an exchange, we may manually process these transactions. We will release details on this process later.

Lastly, we will not contact you directly about any swap details. If you are approached by a Qtum team member, it is most likely an impostor.

Here’s a checklist for your convenience:

Move your Qtum ERC20 tokens to a participating exchange before Oct 4th, 2017 (6pm PST). Wait until the swap completes. Download the Qtum Ignition wallet from https://github.com/qtumproject/qtum/releases Make sure your computer is free from malware or viruses, and wait for the wallet to completely update. Encrypt and back up your wallet, make multiple copies and keep them safe. Do not keep all your backups on one computer, use a DVD-R or USB storage device. Make sure you use a strong password for your backup, and be extremely careful not to lose it. Do a test withdrawal with 1 Qtum main network token from the exchange to your wallet, and then send it back to the exchange. If everything works properly, you can proceed to withdraw your Qtum main network tokens.”

How to Download the Qtum Ignition Wallet

There was a mandatory wallet update, see the changes here:

v1.0.2: Various UI fixes, minor gas overflow consensus fix, per-txout exploit fix, testnet mode setup and functioning

Please download here:

Please remember that after the Qtum ERC20 to Qtum Ignition Main Network swap, you must use the Main Network wallet to withdraw tokens from an exchange.

If you plan to use Changelly.com after October 9th to swap your ERC20 tokens to Qtum Ignition Main Network, you will be asked to provide an Ignition deposit address. This address can only be generated from our Main Network wallet.
