TokenAnvilPERMANENT SETTINGS GUIDE
Revoke mint and freeze authority on Solana
Authority revocation changes who can perform specific actions on a token mint. It can make a supply permanently fixed or remove the ability to freeze token accounts. It is a technical commitment, not proof of good management, legal compliance, market value, or investment safety.
Mint authority versus freeze authority
Mint authority
Allows its holder to mint additional token units. Revoking it prevents future minting and makes the current supply fixed, subject to token burns that can reduce supply.
Freeze authority
Allows its holder to freeze and thaw token accounts. Revoking it removes that power for the mint, so holders cannot be frozen through that authority.
Solana's official SPL Token basics describe both roles and the Set Authority operation used to change or revoke them. The current authority must approve the change.
When revoking mint authority may fit
A fixed-supply game currency, collectible project, or community token may have no legitimate reason to create more supply after launch. Revoking mint authority can make that rule enforceable on-chain. Before doing so, verify that the full intended supply has reached the correct account and that future rewards, treasury allocations, or migrations do not require additional minting.
When keeping mint authority may fit
Loyalty points, controlled game economies, and operational reward systems may need future issuance. Keeping authority is not automatically suspicious when the purpose, controller, limits, and reporting are clearly disclosed. Strong operational security is then essential because a compromised authority could create additional supply.
When revoking freeze authority may fit
A project that promises holders that their accounts cannot be frozen may choose revocation. The on-chain setting can support that statement. However, removing freeze capability can also eliminate a response tool for certain operational or compliance situations. Understand the consequences before making the decision.
Pre-revocation checklist
- Copy and independently verify the exact mint address.
- Inspect current supply, decimals, and existing authority addresses.
- Confirm which authority is being changed; mint and freeze are separate.
- Document why the project is revoking the role.
- Confirm that future operations will never require the authority.
- Test the same workflow on Devnet.
- Read the wallet request before approval and save the transaction signature.
What TokenAnvil's authority protections cost
Base token creation is $4.99. Supply lock, which revokes mint authority, is $2.50. Freeze protection, which revokes freeze authority, is $2.50. Selecting both brings the TokenAnvil total to $9.99. The connected wallet pays Solana network costs separately.
Frequently asked questions
Does revoking mint authority burn tokens?
No. Revocation removes the ability to create additional supply; burning is a separate action that reduces existing supply.
Can TokenAnvil reverse a revocation?
No. TokenAnvil cannot restore an authority that has been permanently removed.
Does revocation guarantee trust?
No. It proves only the specific on-chain authority state. Evaluate the project, operators, disclosures, and use independently.
