Authorities & revocation
A mint has authorities — keys that are allowed to change it. Revoking them is the main trust signal a token can give.
| Mint authority | Can mint new supply. Revoke it to make supply permanently fixed. |
|---|---|
| Freeze authority | Can freeze any holder's token account. Revoke it so balances can't be frozen. |
| Update authority | Can change the token's name, symbol and logo. Revoke it to lock metadata. |
Revoking is permanent
Setting an authority to none cannot be undone. For a fixed-supply community token that's the point — nobody can inflate or freeze it ever again. For a token you still need to manage, keep the authority until you're done.
Where to do it
- During creation — the SPL and Token-2022 creators offer a checkbox.
- Later — Token Manager revokes any authority your wallet still holds.
Token Safety Check reads these fields for any mint and shows you at a glance which authorities are still live.
