Description

I need a script to create a Solana SPL token with the following features:

1. Parameters:

• network: Specify the Solana network for connection (e.g., devnet, mainnet)
• token_name: The name of the token
• token_symbol: The symbol of the token
• metadata_uri: The URI for the metadata JSON file
• num_tokens: The number of tokens to mint

2. Environment Variables

The script should retrieve a private key from environment variables to pay for the transaction.

3. Token Creation

• The script should create the token on the specified network
• Set the token's metadata (name, symbol, URI)
• Mint the specified number of tokens

4. Mint Authority

After minting the tokens, the script should revoke the mint authority.

Additional Considerations:

• Ensure the script handles errors and edge cases (e.g., invalid network, insufficient funds, etc.).
• Please comment your code including instructions on how to use the script
• My preference is that the script is written in JS or Python, but TS or Rust are also acceptable
• Ensure the script adheres to best practices for security, especially when handling private keys.

Acceptance Criteria

A script that runs on Replit and fulfills the above requirements

Please let me know if you need any additional information or if there are any specific requirements I might have overlooked.
