Mint authority: can the dev print more tokens?
Mint authority is the key that can create new tokens out of thin air. If it is still active, the deployer can dilute every holder at will.
What it is
Every Solana token has a mint account. Whoever holds its mint authority can call 'mint' and add supply to any wallet. Renouncing (revoking) that authority makes supply fixed forever.
Why it matters
With mint authority active, a dev can mint billions of tokens and sell them into the pool, crashing the price to zero in one transaction. It is one of the two cleanest rug mechanics on Solana.
What good looks like
'Mint authority revoked' on the report. Most launchpads (pump.fun, BONK.fun) revoke it automatically at launch; tokens created by hand often do not.
Caveats
Revoked mint authority does not stop a dev from dumping tokens they already hold, and it says nothing about liquidity. Read it together with LP lock and holder concentration.
