This Node.js script checks the points balances of multiple Ethereum addresses using the Rainbow API in bulk. It reads addresses from a file, checks their balances concurrently with limited concurrency for efficiency, and logs the addresses with non-zero balances to an output file.
Before running the script, ensure you have Node.js installed on your system. Then, install the required dependencies:
npm install # or yarnPlace your Ethereum addresses in a file, with one address per line. By default, the script reads from addresses.txt in the project's root directory.
To run the script, use:
node index.js
