What are mint and freeze authority?

On Solana, mint authority is the power to create more of a coin, and freeze authority is the power to lock any wallet's tokens so they can't move. When either is still on, one wallet can dilute you or stop you selling. Revoked means nobody holds the power anymore.

Why it matters

New supply pushes down the price of every coin you hold. A freeze stops a sale outright.

How to check

The token's page on Solscan shows both. Coins launched on pump.fun start with both revoked. On Ethereum, Base and BNB Chain the same risk sits in an owner's mint function.

What Neurolith checks

The safety scan says whether mint and freeze are revoked on Solana, and names a mint function or an owner who keeps control on Ethereum, Base, BNB Chain and Robinhood Chain.

A real example

BRETT on Base, checked on 8 October 2026: no one can mint more, no one can freeze, and no owner keeps control of the contract.
