Mint and freeze authority on Solana, and why buyers check them

Why it matters

A mint authority can dilute every holder by minting new supply and selling it. A freeze authority can stop holders from selling. Scanners flag either one as a risk, and many buyers won't touch a token that keeps them.

A token's name, ticker and image have their own update authority. Locking it means nobody can change them later, which scanners show as well.

How T-minus handles it

• On a bonding curve, Meteora's program creates the token without a freeze authority and gives up the mint authority once the supply is minted. You choose who can change the name, ticker and image: nobody (the default), you, or T-minus.
• In a plain pool, minting and freezing are switched off for good and the name, ticker and image are locked, all by default. You keep any of them only by choosing to in the advanced settings, and the review marks that choice before you sign.
• Every token page on T-minus lists what its token launched with: mint and freeze authority, locked metadata, any tax and how much liquidity is locked.

A token you already have

T-minus doesn't change the authorities of a token that already exists. Revoking them is a transaction signed by whoever holds them, and it can't be undone.
