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.
Side by side
| Dimension | Mint authority | Freeze authority |
|---|---|---|
| Attack enabled | Infinite mint / dilution | Freeze accounts (honeypot) |
| Effect on you | Your bag gets diluted to zero | You can buy but not sell |
| Safe state | Renounced (supply fixed) | Renounced (no freezing) |
| Where to check | SPL mint account | SPL mint account |
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.
