Jur will soon bid for a parachain slot to connect to the Polkadot Relay Chain. We would like to offer community members a chance to participate and we will be announcing crowdloan terms soon. In the meantime, there are a couple of easy steps you might want to take to prepare. You will need some $DOT tokens and an official Polkadot browser extension and wallet.

Installing the Polkadot.js browser extension and creating wallet addresses is pretty easy, but you will need a Firefox or Chrome browser. We have broken it into 13 steps, which might seem like a lot, but each step is just a click or two so you will be done in less than five minutes. Once you have your wallet set up, it’s easy to buy $DOT on a centralized exchange like Binance, Kraken, or Kucoin. 

Ready? Let’s go!

Creating a wallet

To install the Polkadot.{js} browser extension for Firefox or Chrome

Go to: https://polkadot.js.org/extension/ 

  1. Click on Add to Chrome and then Add extension


  1. Then click on the extension and Understood, let me continue



  2. Now you can create an account for your wallet extension by clicking on the big “+” button



  3. You will see the seed phrase generated for you. Write it down on a piece of paper and keep it somewhere safe. Don’t store it on your laptop. After you have done this, check the I have saved my mnemonic seed safely box and click Next step



  4. Choose “Allow use on any chain”
    In the Polkadot, the address formats are specific to parachains, but choosing “Allow on any chain” will generate a generic substrate address starting with “5” which is compatible with the entire ecosystem and can be later used to derive parachain specific addresses as well.



  5. Then create a wallet name and the password and click Add the account with the generated seed
  6. Congratulations! You have created your wallet.



  7. You should create and export a JSON file in case you want to access your account from another device. To create and download your JSON file, click on the polkadot.js extension again in the top line of your browser. You will see your account in the pop-up window.



  8. Click on the three dots beside your account and then click Export Account to create the JSON file



  9. Type in your password and then click I want to export this account
  10. After the file is downloaded, save it on an external storage device that is not connected to your laptop. Keep it safe! This is how you will access your account if you want to use it on a different device.



  11. To access your new wallet, you need to go back to https://polkadot.js.org/ and click on the link under apps wallet (hosted) or you go straight to https://polkadot.js.org/apps/#/explorer
  12. The app will ask to access your wallet, click Yes, allow the application to access

Funding wallet with $DOT

  1. You can purchase $DOT from Binance, Coinbase, and Kraken with crypto or fiat. You can also buy $DOT on  Kucoin, Bitfinex, Bybit, and several other exchanges but only with crypto; these exchanges don’t offer $DOT for fiat.
  2. You will need to withdraw/transfer $DOT from an exchange to your polkadot wallet in order to participate in the crowdloan.
  3. Please refer to your preferred exchange’s guide to understand how to withdraw.
  4. Due to different address formats within Polkadot, it is likely that the Polkadot address starting with “5” might not be compatible with the exchange. In such case, follow this tutorial to generate a polkadot relay chain specific address that starts with “1”. Use this address in the exchange to withdraw.
  5. After you have successfully transferred $DOT into your wallet, it is important to switch back to the original settings so that you can see the original substrate address starting with “5” before contributing to the Crowdloan. Jur chain will only be able to transfer $JUR tokens for crowdloan rewards to addresses beginning with “5”, and the address you use to contribute is also used for your rewards.
  6. Please note: VeChain $JUR are VIP-180 tokens so you cannot send them to your Polkadot wallet. You must wait until the token migration feature is available to swap your VeChain $JUR for Pplkadot $JUR and have them sent to your wallet.

Some other considerations to keep in mind while preparing for crowdloan

  1. Only contribute with a wallet address starting from “5”. It is a must for Jur chain. Otherwise, we will not be able to guarantee crowdloan rewards.
  2. Auctions bids can be very dynamic. The market conditions will dictate the reward structure. It will be released close to the auction, please keep an eye out for announcements on Jur’s social channels & community on Discord. While the reward ratio and complete reward delivery schedule has not yet been finalized,   Jur has decided that 10% of the rewards will be immediately transferred once Jur chain is live as a parachain.
  3. The minimum contribution is 5 $DOT.
  4. You will be required to maintain at least 1 $DOT in your wallet. Balances of less than 1 $DOT get purged after the transaction that brings them below the minimum. For example, if you have 106.3 $DOT in your wallet and you contribute 106 to the crowdloan, the remaining 0.3 will be purged. But if you contribute 105, the remaining balance will be 1.3 $DOT.
  5. A crowdloan lease can last for up to 2 years. Your $DOT will be locked for the same duration and will not be accessible. Once the lease is over, $DOT will be automatically transferred back to your account.
  6. In case Jur does not win the auction, the $DOT will be transferred back to your account immediately after the auction.
