Stargaze to Cosmos Address Converter

A simple utility to convert Stargaze (stars) addresses to Cosmos Hub (cosmos) addresses and check their balances.

Installation

npm install

Usage

Converting Addresses

1. Create a file named wallets.csv with Stargaze addresses. The addresses should be in the first column.

Example wallets.csv:

StargazeAddress
stars1abcdefghijklmnopqrstuvwxyz0123456
stars1zyxwvutsrqponmlkjihgfedcba9876543

2. Run the conversion:

npm start

3. Find the converted addresses in output.csv.

Checking Balances on Cosmos Hub

After converting addresses, you can check their balances on Cosmos Hub:

npm run check-balances

This will:

1. Read the converted addresses from output.csv
2. Check the balance of each Cosmos Hub address
3. Create a new file called hub.csv with Stargaze addresses, Cosmos Hub addresses, and their balances
4. Addresses with zero balance will be included with a balance of "0"

How it works

This tool uses the bech32 encoding/decoding to change the address prefix from 'stars' to 'cosmos' while preserving the underlying public key data.

The balance checker connects to the Cosmos Hub REST API to query account balances for each converted address.
