What is mint authority on Solana?
Short answer
Mint authority is the on-chain permission to create new units of a Solana token. Whoever holds it can print additional supply at will, diluting every existing holder.
If mint authority is live, a team can inflate supply and crash the price at any time. "Renounced" mint authority means the permission is set to null and supply is fixed forever — a baseline safety check, though not a complete guarantee on its own.

How do I check mint authority?
Look up the token mint on an explorer like Solscan; it shows whether mint authority is enabled or renounced.
Is renounced mint authority enough to be safe?
No. It only removes the infinite-mint risk. You still need to check freeze authority, LP status, and holder concentration.
What happens if mint authority stays live?
The holder can mint large amounts of new supply and sell it into the pool, diluting holders and crashing the price.
