Token Supply & Decimals Explained
Supply and decimals together define how many tokens exist and how divisible they are. Getting them right at launch matters, because they affect pricing, display and how supply is stored on-chain.

Token Supply & Decimals Explained
Plan it in the JetMintAi terminal, review the exact transaction, and approve it from your own wallet — non-custodial from start to finish.
How it works
- Decimals set divisibility — 9 decimals means 1 token = 1,000,000,000 base units.
- On-chain, supply is stored in base units (amount × 10^decimals).
- Most memecoins use 6–9 decimals; stablecoins often use 6.
- Total supply × decimals must be computed exactly to avoid errors.
Avoiding supply mistakes
A common bug is losing precision on large supplies or truncating comma-formatted numbers. JetMintAi computes supply as exact big-integer base units, so a supply like 1,000,000 mints exactly — not a rounded or truncated amount.

Frequently Asked Questions
What decimals should I choose?
9 is a common Solana default; 6 is common for stablecoins. Choose based on how divisible you want the token.
Can I change decimals later?
No. Decimals are fixed at mint creation, so decide before launching.
Why did my supply mint wrong elsewhere?
Usually a precision or comma-parsing bug. Exact base-unit math (big integers) prevents it.
