Authorities & revocation
Authorities are the keys allowed to change a mint. Whether they have been revoked is one of the first things buyers check.
| 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. Keep it until you're done managing the token.
Where to do it
- At creation, using the checkboxes in the SPL and Token-2022 creators.
- Later, in Token Manager, for any authority your wallet still holds.
Token Inspector shows which authorities are live on any mint.
