Decimals

The number of decimal places for a token, stored on the mint account. Determines how raw integer amounts map to human-readable values: a mint with 6 decimals means 1,000,000 raw = 1.0 token. Common values: 0 (NFTs), 6 (USDC/USDT), 9 (SOL, most DeFi tokens). Cannot be changed after mint creation.
