After many requests by users to integrate Kusama Network to [**Rotki**](https://rotki.com/), the Rotki team aims to integrate with Kusama: This means to have the Kusama blockchain at the same level of handling as Ethereum and Bitcoin for Rotki, allowing to account imports, balance queries, transaction querying and eventually staking information. Milestone 1 has been completed and this is a submission to cover milestone 2!

Rotki is an open source portfolio tracker, accounting and analytics tool that respects your privacy. The mission is to bring transparency into both the crypto and traditional financial sectors through the use of open source. Most importantly, unlike virtually every other competing service which consists of closed source webapps onto which you are forced to hand over all your financial data, with Rotki your data is stored encrypted locally in your computer.

More information on the proposal, timelines & allocations can be found [here](https://docs.google.com/document/d/1OwdIcrAqDxMpDcIRTE7wbJU0aO2gGfZplyEI7s1oWPo/edit?usp=sharing). 

Specifically for Milestone 2 we will:

- Perform transaction history query for the imported addresses by using either the connected KSM node (or an open node if one exists) and show them in the Rotki UI in the blockchain transactions component.
- Detect if any of the user’s addresses are actively staking, and if yes show how much profit they have made (counting historical KSM prices) and show expected profits in the UI. Also calculate profit for addresses that have staked so far in the past and take it into account in the PnL report for a given period.
- Add the staking information in the Rotki UI staking component so users can see a break down of staking info per address.




 Approve a proposal. At a later time, the proposal will be allocated to the beneficiary
 and the original deposit will be returned.
