Mint authority vs Freeze authority: what's the difference?

Two Solana permissions that should usually both be renounced — but they enable different attacks.

The short version

Two Solana permissions that should usually both be renounced — but they enable different attacks.

  • Mint authority: The power to create new token supply, diluting holders.
  • Freeze authority: The power to freeze a holder's account, blocking transfers and sells.

Which one should you care about?

Key idea — Renouncing one is not enough. Confirm both mint and freeze authority are renounced — they close different doors.
