WinChain Mainnet Upgrade Announcement

Dear WinChain users:

With a mission to revolutionize the global lottery industry with the latest decentralized technology, WinChain is committed to develop a decentralized lottery technology platform capable of supporting large-scale blockchain based lotteries. The WinChain team has been working tirelessly on the world’s first blockchain based national lottery system since day one.

After analysing the results of 3 months rigorous testing on various scenarios, and to make sure we can deliver the best experience possible in the upcoming issuance of the world’s first blockchain based national lottery ticket, we’re pleased to inform you that our Mainnet will receive a major update today, this update introduces a variety of features focused on decentralized technology that will bring better token economics, easier node selection, easier maintenance (theoretically no hard fork).

Most importantly, the existing ERC20 based $WIN token will migrate to the latest WinChain mainnet and become native $WIN token in a 1:1 ratio.

Together, with all these changes, we believe more dynamics will be brought into the WinChain developer ecosystem and we want to say a big thank you to the developers that have put their time to make this happen!

$WIN token hold in cryptocurrency exchanges

The existing ERC20 based $WIN token are officially supported and available for trading on cryptocurrency exchanges including OKEx and CoinMEX. If you have ERC20 based $WIN tokens on any of the above mentioned exchanges, you do not need to do anything other than follow the exchange’s instructions. Both exchanges will convert your ERC 20 based $WIN token held in your user accounts into $the new native $WIN token in 10 business days at the fixed exchange rate of 1:1. Please refer to each exchange’s announcement for detailed procedures.

Note: OKEx has completed its work to switch to the latest WinChain mainnet, and the depositing and withdrawal of native $WIN token resumed at 10:00AM (CET) March 12th, 2019 according to its latest announcement.

CoinMEX has announced the suspension of exchanging the ERC20 based $WIN token and $ Luckywin token at 17:00 (UTC+8) on March 12th, 2019. Please stay tuned for CoinMEX’s further announcement.

If you have tokens on any one of the non-official exchanges that does not support WinChain’s latest mainnet upgrade, you should withdraw your tokens to a compatible wallet that you own the private key for.

$WIN token hold in users’ wallets

If you don’t hold your existing ERC20 based $WIN token on an exchange, you need to have the private key of the wallet that holds your tokens. WinChain will take a snapshot of all transactions that matches users’ wallet addresses, and migrate the existing ERC20 based $WIN token to the upgraded mainnet which you can access from the Winchain wallet using your own private key.

Please follow the following procedure to access your native $WIN token manually:

• Open your wallet app (such as imToken or MyToken);
• Select the ERC20 wallet that holds your ERC20 based $WIN tokens;
• Export your Mnemonic Phrase, Keystore, or Private Key;

• On your mobile, download the WinChain wallet app from win.winchain.vip and get it installed;
• Select “Get a Free Wallet”;

• Select import wallet and input the Mnemonic Phrase, Keystore, or Private Key that you just exported in step 3.
