How to read mint and freeze authority
Mint authority controls whether additional units can be minted. Freeze authority can freeze individual token accounts. Read the exact mint account, not a ticker or screenshot. An authority address identifies a control; it does not by itself prove misuse.
None means that particular authority is absent. Unknown means the check did not establish it. Those are different results. Token extensions can introduce additional controls, so absent mint and freeze authorities do not establish that a token is safe.
See a real wrapped-SOL observation with authority evidence and unavailable checks.
Vectora may return a partial report when a provider is unavailable. Missing metadata or liquidity evidence stays unknown. Save the observation timestamp and recheck when you need current evidence; a saved report does not monitor continuously.
