getTokenSupply

Returns the total supply of an SPL Token mint. This includes the raw amount, decimal count, and human-readable formatted values. Knowing a token's total supply is fundamental for market cap calculations, tokenomics analysis, and understanding token inflation or deflation over time. This method queries a single mint address and returns its current total minted supply.
