Solana Token Balance Checker

This script fetches the balance of a specified Solana token for all addresses listed in a JSON file. It supports checking the native SOL balance as well as SPL token balances.

Requirements

• Python 3.6+

Setup

1. Clone the repository and navigate to the project directory.

2. Create a .env file with the following content:

   RPC_URL=https://api.mainnet-beta.solana.com
   TOKEN_CONTRACT=B6h248NJkAcBAkaCnji889a26tCiGXGN8cxhEJ4dX391

   Replace the RPC_URL and TOKEN_CONTRACT values with your own. For tracking the native SOL balance, set TOKEN_CONTRACT to 0x0.

3. Create a solana_wallet.json file with the following content:

   [
     {
       "isConnected": true,
       "address": "DHAzXyqVFqw31qX6Jhvm8o6QPBKy67dAYRjMiVMuG4tm",
       "balance": null,
       "isDisabled": false,
       "type": "SOL",
       "phrase": "-=--=-=-=-",
       "label": null,
       "ens": null,
       "group": ["Personal Group"]
     }
   ]

   You can also generate a sample JSON file using the Makefile:

   make example

Usage

1. To install dependencies and run the script:

   make all

2. To install dependencies only:

   make setup

3. To run the script only:

   make run

4. To clean up generated Excel files:

   make clean

5. To create a sample solana_wallet.json file:

   make example

6. To display help information:

   make help

Tracking Native SOL Token

To track the native SOL balance, set the TOKEN_CONTRACT variable in your .env file to 0x0:

RPC_URL=https://api.mainnet-beta.solana.com
TOKEN_CONTRACT=0x0

This will make the script query the native SOL balance for the given wallet addresses.

Tracking SPL Tokens

To track an SPL token balance, set the TOKEN_CONTRACT variable in your .env file to the mint address of the SPL token:

RPC_URL=https://api.mainnet-beta.solana.com
TOKEN_CONTRACT=B6h248NJkAcBAkaCnji889a26tCiGXGN8cxhEJ4dX391

Replace B6h248NJkAcBAkaCnji889a26tCiGXGN8cxhEJ4dX391 with the mint address of your desired SPL token.

Output

The script will save the wallet balances to an Excel file named solana_<TOKEN_CONTRACT>.xlsx.
