Darwinia Apps Guide Part Ⅰ: Account

Published in
3 min readFeb 25, 2022


We will launch a series of articles to help users understand Darwinia’s tools, and this article is a tutorial to the new version of Apps.


In the new version, aside from the UI/UX updates, the biggest update is that we no longer support users to create accounts inside Darwinia Apps, but adopt a simpler way to support users to import accounts from the Polkadot{.js} extension. This will greatly reduce the cost for users.

If you are a user who has never used Polkadot{.js} extension, please refer to the tutorial in the first part of this article; if you are a user who has used the old version of Darwinia Apps, please refer to the second part of this article to migrate the old account.


Not all old accounts need to be migrated, and accounts that have been imported into the Polkadot{.js} extension do not need to be migrated, meanwhile, these accounts will not be displayed in the「Account Migration」.

How to Connect Polkadot{.js} Extension to Darwinia

This part will walk you through the process of connecting your polkadot{.js} extension to Darwinia.

Install the Polkadot{.js} Extension

If you do not already have the polkadot{.js} extension installed, you can install the extension from the Chrome store. For help with installation, you can follow the Getting Started with the polkadot{.js} extension guide from the official polkadot{.js} extension documentation. Once you have installed the polkadot{.js} extension, follow the account creation wizard. Make sure to store your mnemonic safely and do not share it with anyone. If you prefer, there is also a video tutorial that you can check out here.

When the polkadot{.js} extension is fully set up, you’ll have your address displayed at the top of the extension window.

Connect to Darwinia

Once you have an account, you can enter Apps Lite and connect to Darwinia by clicking 「Connect Wallet」on the right corner of the top, and you also can switch the network connected by clicking and choosing the network through the button on the left upper.

Account Migration

If your accounts are in the old version and cannot be found in your polkadot{.js} extension, you can restore account JSON through 「Account Migration」and add the JSON to polkadot{.js} extension.

  • Go to Apps Lite, click 「Export JSON」 to download JSON file from 「Account Migration」.
  • Add the JSON file to polkadot{.js} extension There is a video tutorial that you can check out here.
