# Token tools

These tools work on a token that already exists. Once your mint is live, this is where you fix its details, add to the supply, or remove some from circulation. Pick the one that matches what you need to change. Each one leans on a token authority, so it helps to know how those work first, see [Authorities explained](/concepts/authorities.md).

| Tool                                               | What it does                                | Fee  | Best for                                                                                |
| -------------------------------------------------- | ------------------------------------------- | ---- | --------------------------------------------------------------------------------------- |
| [Update Metadata](/tools/token/update-metadata.md) | Edit the name, symbol, image or description | Paid | Fixing a typo or swapping the logo while you still hold the update authority            |
| [Token Mint](/tools/token/token-mint.md)           | Mint more supply to a wallet you choose     | Paid | Adding to the supply when the launch needs more tokens and mint authority is still live |
| [Burn Tokens](/tools/token/burn-tokens.md)         | Permanently destroy tokens from a wallet    | Paid | Removing tokens from circulation, no authority needed since it spends your own balance  |

Exact fees are on the [Fee schedule](/reference/fee-schedule.md).

## Which one should I use?

The cards above give the one-line version. The difference that usually decides it is which authority each tool leans on. [Update Metadata](/tools/token/update-metadata.md) rewrites the on-chain name, symbol, and image, but only while you still hold the update authority. [Token Mint](/tools/token/token-mint.md) needs the mint authority to add supply. [Burn Tokens](/tools/token/burn-tokens.md) asks for neither, since it only spends tokens already in your wallet. The table in the next section lays that out tool by tool.

{% hint style="warning" %}
[Update Metadata](/tools/token/update-metadata.md) only works while you still hold the **update authority** on the token. Revoke that authority and the name, symbol and image are locked forever. So edit first, lock later. More on this in [Authorities explained](/concepts/authorities.md).
{% endhint %}

## Authorities and what they unlock

Two of these tools depend on a token authority, and one does not. An authority is the key that lets a specific change happen on-chain, and revoking one is permanent. Knowing which tool each authority powers helps you decide what to lock and when.

| Tool                                               | What it needs     | Notes                                                              |
| -------------------------------------------------- | ----------------- | ------------------------------------------------------------------ |
| [Update Metadata](/tools/token/update-metadata.md) | Update authority  | Lost the moment you revoke update authority. Edit before you lock. |
| [Token Mint](/tools/token/token-mint.md)           | Mint authority    | Lost the moment you revoke mint authority. Supply becomes fixed.   |
| [Burn Tokens](/tools/token/burn-tokens.md)         | Just your balance | No authority required. You can always burn tokens you hold.        |

When you are finished editing and minting, the [Secure and lock](/tools/secure.md) tools revoke these authorities so holders can trust the token. To read what each authority controls in plain terms, see [Authorities explained](/concepts/authorities.md).

## A common order of operations

{% stepper %}
{% step %}

### Create the token

Mint it with [Token Creator](/tools/launch/token-creator.md) or one of the other [launch tools](/tools/launch.md).
{% endstep %}

{% step %}

### Get the details exactly right

Fix any typo or swap the logo with [Update Metadata](/tools/token/update-metadata.md). Mint extra supply with [Token Mint](/tools/token/token-mint.md) if the launch needs it.
{% endstep %}

{% step %}

### Lock it down

Once everything is final, revoke the authorities so buyers see a fixed token. See [Revoke Update Authority](/tools/secure/revoke-update-authority.md), [Make Immutable](/tools/secure/make-immutable.md), and the [rug-proof guide](/guides/rug-proof-token.md).
{% endstep %}
{% endstepper %}

{% hint style="info" %}
Order matters here. Once update authority is gone, [Update Metadata](/tools/token/update-metadata.md) can no longer touch the token, and once mint authority is gone, [Token Mint](/tools/token/token-mint.md) cannot add supply. Burning still works either way, because it only spends your own balance.
{% endhint %}

{% hint style="warning" %}
**About fees.** Every action has two costs: the Solana **network fee** paid to validators, and the **J Tools platform fee**. The platform fee always shows in the app before you confirm, and nothing is charged until you sign. Fees can change over time, so trust the in-app summary rather than a number you saw once.
{% endhint %}

## FAQ

<details>

<summary>I revoked an authority. Can I still use these tools?</summary>

It depends on the tool. Revoking update authority disables [Update Metadata](/tools/token/update-metadata.md) for that token, and revoking mint authority disables [Token Mint](/tools/token/token-mint.md). [Burn Tokens](/tools/token/burn-tokens.md) keeps working regardless, since burning only needs the tokens in your wallet.

</details>

<details>

<summary>Does J Tools ever hold my token or keys?</summary>

No. You connect a wallet, the tool builds the transaction, and you sign it yourself in the wallet. Keys never leave your side.

</details>

<details>

<summary>Should I lock metadata before or after editing it?</summary>

After. Set the name, symbol and image with [Update Metadata](/tools/token/update-metadata.md), confirm they look right everywhere, then revoke the update authority. Locking first throws away your ability to fix anything.
