How to Manage a Token After Launch on Sui

Open token management with the wallet that holds the right capabilities. Metadata updates, minting, burning and blacklist changes require on-chain permissions. Current service fees are 5, 1, 1 and 1 SUI respectively, plus gas; giving up a capability is usually irreversible.

Know which capabilities the wallet holds

A TreasuryCap allows token administration such as minting, burning and metadata changes. Holding the token itself does not give a wallet those rights.

Freezing addresses is a separate capability. A blacklist cannot be added to a token that was launched without it.

Record irreversible changes

Minting, burning and giving up permission change what holders and the project team can expect. Write down why the action is needed, then keep the digest and the before-and-after supply or metadata.

Updating metadata does not change the token name, symbol, decimals or original supply. Those fields are fixed in the contract.

Hand over more than a private key

A team handoff should include the wallet, full coin type, TreasuryCap and DenyCap locations, blacklist state and the relevant transaction history. A key alone leaves the next team guessing what the project can still do.

How it works

Follow these steps to complete the task safely.

  1. 01
    Connect the issuing walletUse the wallet that issued the token or holds its capabilities. Another wallet can read some information but cannot administer the token.
  2. 02
    Select the exact tokenChoose it from the list or paste the complete coin type. Do not rely on a token name for an irreversible action.
  3. 03
    Open the right consoleMetadata, minting, burning, blacklist and permission management each have a separate workflow.
  4. 04
    Confirm the effectMinting increases supply, burning permanently reduces it, and giving up a capability may remove several management actions at once.
  5. 05
    Keep a recordSave the transaction digest and the supply or metadata values before and after the change.

FAQ

Common questions about this tool and its fees.

Can every token be blacklisted?

No. Only tokens launched with the blacklist feature have the permission needed to freeze and unfreeze addresses.

Does giving up mint permission affect other actions?

Yes, usually. Minting, burning and metadata updates share the TreasuryCap, so giving it up can remove all of those controls.

Does burning reduce circulating supply?

Yes. Burning permanently removes the token amount, and the action cannot be reversed. Check the coin type and amount before signing.

Why is a token missing from my list?

The list is built from the connected wallet’s issued tokens and capabilities. You can search by full coin type, but you still need the right capability to make changes.
