7️Set Solana Token Authority: Minting, Freezing, and Removing

Setting Solana SPL Token Authority Without Code

After creating a token on the Solana blockchain, it comes with three authorities:

• Mint Authority: Allows minting new tokens to increase the supply.

• Blacklist/Freeze Authority: Allows freezing any address to prevent transfers and sales.

• Update Metadata Authority: Allows modifying the token's name, logo, etc.

If a token is created using PandaTool , it will include all three authorities by default. Tokens created on other tools may only include two or even one authority.

Regardless of where the token was created, you can use PandaTool to revoke authorities or use the freeze functionality to manage token authorities effectively.

1. Revoking Authorities

PandaTool recommend that all authorities are revoked after creating a Solana token.

1. Open the authority management page: https://solana.pandatool.org/en/control

2. Enter the token's contract address. You may see the following messages:

   • "No authority for the current address": If you have already revoked all authorities, the system will show messages like: "Token update metadata disabled," "No mint authority for the current address," or "No freeze authority for the current address."

     • This means your wallet no longer has authority over the token. If you haven’t revoked the authority, ensure the correct creating wallet is connected and try again.

• No messages displayed: If no message appears, you can proceed to revoke the authority. Select the authority you wish to revoke, then confirm.

2. Using Authorities

If you do not wish to revoke authorities, you can use the authority management tools to mint tokens or freeze accounts.

Minting Tokens

1. Open the authority tool and select the "Mint Tokens" option.

2. Enter the quantity to mint and confirm.

3. After wallet confirmation, a "Minting successful" message will appear.

Example: A token with a total supply of 1,000 tokens displayed on the block explorer can be increased by minting an additional 1,000 tokens.

Freezing/Unfreezing Accounts

Freezing accounts (also called blacklisting) prevents an address holding the token from transferring or selling it.

1. Open the authority tool and select "Freeze Account."

2. Enter the target wallet address and confirm.

3. To unfreeze, simply select "Unfreeze Account" and confirm.

When an address is frozen, attempts to transfer tokens will display an error like “Unable to send.” This indicates the freeze action was successful.

• Note: The address to be frozen must be the wallet address, not the account address.
