EWT Token Balance

This application contains multiple scripts to retrieve the EWT token balance of an account dynamically or for specific months or blocks from Energy Web Chain.

1. Getting Started

The following instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

1.1. Prerequisites

Please make sure you've already installed following dependencies:

npm >=6.11.3
node >=10.16.3

1.2. Installing

Follow the steps below to have development environment running:

1. Clone the repository:

git clone https://github.com/olisystems/ewt-balance.git

2. Change directory to the cloned folder and install all requisite npm packages (as listed in package.json):

cd ewt-balance
npm install

2. Get Balance

1. To get the balance up to 01-07-2020, run the following command in the terminal:

$ npm run balanceByBlock

2. Run the following command in the terminal to get the balance for specific timestamps:

$ npm run balanceByMonth

3. Currently, to get the balance dynamically requires a much longer time (up to several days). To get the balance dynamically, run the following command in the terminal:

$ npm run dynamic

4. Instead of starting from an early block, use the last known block number as a starting point and get the block number for next month using the getBlockNumber.js. Then put this block number into blocks array of block-balance.js script.

   For example, we can see from the block-balance.js that the last calculated block number is 6505859. We can use this block number as a starting point in the getBlockNumber.js file and use the next month as timestamp. Hence we will get the block number for the next month that we can use in the block-balance.js script.

   Run the following command to get the block number for the specified timestamp:

$ npm run getBlockNumber

Updated 01.06.21

1. Run node getBlockNumber.js
2. Copy block numbers from console to BLOCKS.js array
3. Run node block-balance.js
