# Advanced Protections

Set rules for your token’s opening trading period and adjust fees based on trade size, repeat trading or volatility

These features are <mark style="color:$primary;">**optional.**</mark> Choose the settings that suit your launch rather than enabling everything

{% hint style="info" %}
Available protections depend on your network, DEX and launch type. **Tiered Fees and Dynamic Fees cannot be enabled together**
{% endhint %}

<details>

<summary><strong>Launch Protection</strong></summary>

Limit how much each wallet origin can buy during the opening launch period

* **Protection Period:** Choose how long the restrictions remain active
* **Who Can Buy:** Allow public buying or restrict access to approved wallets
* **Maximum Buy:** Set the percentage of total supply each wallet origin can purchase during that period

*<mark style="color:$primary;">Example: With 100 million tokens, a 0.1% limit allows each wallet origin to buy up to 100,000 tokens during the first 5 minutes</mark>*

{% hint style="info" %}
This helps limit early accumulation by individual wallets, but does not guarantee an even distribution across buyers
{% endhint %}

<details>

<summary><strong>Cooldown Protection </strong><em><mark style="color:$info;"><strong>(EVM Only)</strong></mark></em></summary>

Discourage rapid repeat trading from the same wallet origin

* **On a DEX:** Repeat trades within the configured cooldown period incur an additional fee on top of the Fee Builder fee
* **During an LBP sale:** The cooldown sets a minimum delay before the same wallet origin can trade again

*<mark style="color:$primary;">DEX example: With a 1% Fee Builder fee and a 5% cooldown surcharge, a qualifying repeat trade pays 6% in total</mark>*

{% hint style="info" %}
**Cooldown fees can trigger strong warnings on token scanners.** Review the effect on ordinary traders before enabling them
{% endhint %}

<details>

<summary><strong>Tiered Fees </strong><em><mark style="color:$info;"><strong>(EVM Only)</strong></mark></em></summary>

Adjust the configured fee according to trade size: <mark style="color:$primary;">**larger buys receive a discount, while larger sells pay more**</mark>

The strongest matching tier applies. The tiers do not add together

With a configured fee of **1%**:

* **Buy over 0.5%:** A 25% discount reduces the fee to **0.75%**
* **Buy over 1%:** A 50% discount reduces the fee to **0.5%**
* **Sell over 0.5%:** A 100% increase raises the fee to **2%**
* **Sell over 1%:** A 200% increase raises the fee to **3%**

{% hint style="info" %}
These are changes to the configured fee, not extra percentage points. Tiered Fees affect trading costs but do not prevent large sells
{% endhint %}

<div data-with-frame="true"><figure><img src="https://3527517113-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FY8k5Pri8O9lw2SMUjS2v%2Fuploads%2FS49LZ1AmdtTJ3Vs8dawH%2Fimage.png?alt=media&amp;token=47dc5f75-3b47-4c7f-885c-215599521f46" alt=""><figcaption></figcaption></figure></div>

</details>

<details>

<summary><strong>Dynamic Fees</strong></summary>

Temporarily increase the configured total fee when volatility triggers, with the effect decaying over your selected period

* **Fee Increase:** Choose how much the configured fee rises
* **Trigger:** Check volatility **per swap** or **per block**
* **Volatility Decay Period:** Choose how quickly the volatility effect decays.

*<mark style="color:$primary;">Example: A 25% increase changes a configured 1% fee to 1.25% when triggered. It does not add a 25% trading fee</mark>*

{% hint style="info" %}
Dynamic Fees let trading costs respond to volatility. They do not guarantee price stability or prevent manipulation
{% endhint %}

#### Before Enabling Protections

Check how your settings affect both **buys and sells**, including any additional fees or waiting periods. Make these rules clear to your community before launch
