✦ Key Insight

An active mint authority makes every supply figure meaningless and gives one party the ability to dilute all holders instantly.

✕ Common Misconceptions

Accepting a promise to renounce later. Verify on-chain now. Also check the freeze authority in the same view — the two together give near-total control.

Detailed Explanation

If a mint authority is active, whoever holds it can inflate supply without limit and sell into the market. Legitimate projects usually renounce it after launch, or move it to a governance contract or multisig. On Solana this is an explicit field on the token account and can be checked directly.

In Practice

“A token scanner shows the mint authority still set to the deployer wallet. Days later, supply doubles and the price collapses.”
