Definition

Decimals define how many fractional digits a token uses. SOL uses 9 decimals (1 SOL = 1,000,000,000 lamports). USDC on Solana uses 6. Most meme coins use 6 or 9 decimals.

Decimals are fixed at mint creation and cannot change. Choosing the right value at mint matters for user readability and market pricing. Decimals are permanent — pick them at mint.
