# Secure and lock

Trust on Solana is something you prove on-chain, not something you claim in a tweet. These tools remove the powers that let a token's creator change the rules after people have bought in. Revoke the mint, freeze, or update authority and that power is gone for good. Buyers and explorers can read all of this, so locking the right authorities is how a token earns the word "safe." If you're new to what these powers are, start with [Token authorities](/concepts/authorities.md).

**This cannot be undone.** Once this transaction confirms on-chain, there is no way to reverse it. Check every field before you sign.

## Which one should I use?

* **Locking supply only?** [Revoke Mint Authority](/tools/secure/revoke-mint.md).
* **Proving you can't freeze holders?** [Revoke Freeze Authority](/tools/secure/revoke-freeze.md).
* **Done editing the name and logo?** [Revoke Update Authority](/tools/secure/revoke-update-authority.md).
* **Want all three gone in a single signature?** [Make Immutable](/tools/secure/make-immutable.md).
* **Need to freeze or unfreeze one account?** [Freeze Account](/tools/secure/freeze-account.md) or [Unfreeze Account](/tools/secure/unfreeze-account.md).

A quick way to read it: revoke a **single** authority when you still want to keep the others, for example lock supply now but keep the ability to fix metadata later. Reach for **Make Immutable** when the token is finished and you want every authority gone at once.

{% hint style="info" %}
Freeze and Unfreeze are different from the revoke tools. They act on one holder account at a time, and they need the freeze authority to still exist. If you have already revoked freeze, you cannot freeze anyone, which is the whole point of revoking it.
{% endhint %}

{% hint style="info" %}
[Auto Freeze](/tools/secure/auto-freeze.md) is being built. It will freeze accounts that match a rule for you, so you don't have to watch and freeze each one by hand. It is not live yet.
{% endhint %}

## How locking builds trust

Each authority is a power the creator holds over the token after launch. Revoking one removes that power for good and writes the change on-chain for anyone to verify.

{% stepper %}
{% step %}

### Finish your setup first

Get the name, symbol, image and supply exactly how you want them. Revoking comes last, because there is no undo.
{% endstep %}

{% step %}

### Revoke what you don't need to keep

Lock the mint to fix supply. Lock freeze so holders are never stuck. Lock update so metadata can't be swapped. Use one tool per authority, or [Make Immutable](/tools/secure/make-immutable.md) for all three.
{% endstep %}

{% step %}

### Let buyers verify

Once revoked, the authority reads as "none" on explorers and in safety checkers. That is the on-chain proof people look for before they buy.
{% endstep %}
{% endstepper %}

For what mint, freeze and update authorities actually control, see [Token authorities](/concepts/authorities.md). For a full launch-to-locked walkthrough, read [Make your token rug-proof](/guides/rug-proof-token.md). When you're ready, [open the tools in the app](https://j.tools/en/tools) and revoke from your own wallet.

## FAQ

<details>

<summary>Can I undo a revoke?</summary>

No. Revoking an authority is permanent, and there is no way to restore it. That permanence is exactly what makes a revoked token trustworthy. The one pair of tools that acts on live accounts, Freeze and Unfreeze, can be reversed, but only while the freeze authority still exists.

</details>

<details>

<summary>Do I have to be the current authority?</summary>

Yes. You can only revoke an authority your connected wallet currently holds. If an authority was already handed to another wallet or removed earlier, these tools cannot touch it from your side.

</details>

<details>

<summary>Does locking authorities stop trading or liquidity?</summary>

No. Revoking mint, freeze or update has no effect on transfers, pools or swaps. It only removes your ability to mint more, freeze accounts, or edit metadata.

</details>

<details>

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

No. Every action is signed in your own wallet, and keys never leave it. See the note below.
