Explanation

1. Get account info: Retrieve the raw account data for the mint
2. Parse mint data: Use the MINT_LAYOUT to parse the binary data
3. Create MintInfo: Convert parsed data into a structured MintInfo object
4. Display information: Show all the mint properties

Key Concepts

• Mint account: Contains metadata about a token type
• Decimals: Number of decimal places for the token
• Supply: Total number of tokens in circulation
• Authorities: Accounts that can mint tokens or freeze accounts
• Initialization: Whether the mint has been properly set up

Usage

python get_token_mint.py

This will output:

Mint Address: 4zMMC9srt5Ri5X14GAgXhaHii3GnPAEERYPJgZJDncDU
Decimals: 6
Supply: 1000000000
Is Initialized: True
Freeze Authority: None
Mint Authority: AC5RDfQFmDS1deWZos921JfqscXdByf8BKHs5ACWjtW2
