Polka-store is a Node.js program written in typescript which scans a Polkadot chain (Polkadot/Kusama/Westend) and stores (hopefully all) balance-relevant transactions in a SQLite database. This database can be used in other projects to easily access the transaction data. What is balance-relevant? 

Currently the following data will be collected:

- Balance transfers (directly and through reserved balance)
- Fees
- Staking rewards
- Staking slashes
- Additionally to the balance-relevant transaction data, also changes in bonded amounts are stored.

The source for the solution is available at [https://github.com/TheGoldenEye/polka-store](https://github.com/TheGoldenEye/polka-store) and Goldeneye's credentials are included on the Readme.md.
