* **Recommended format**: Square image (1:1 aspect ratio)

### Token description

The description field allows you to provide detailed information about your token and project. This text appears in wallets, explorers, and other platforms that display token information, making it crucial for user understanding and adoption.

#### What to Include in Your Description

**Project Purpose:** Clearly explain what your token does and why it exists. Users should understand your project's core mission within the first sentence.

**Token Utility:** Describe how people can use your token - whether for governance, payments, rewards, staking, or other functions.

**Unique Value Proposition:** Highlight what makes your project special and different from other tokens in the ecosystem.

**Community and Ecosystem:** Include relevant information about your community, partnerships, or ecosystem integrations.

**Technical Information:** Mention any important technical features, such as special tokenomics or innovative mechanisms.

In the 20lab generator, the metadata authority is assigned to your deployer address by default. This provides flexibility to make corrections or updates later through the token owner dashboard. However, if you're confident everything is correct, you can revoke the metadata authority by setting it as immutable from the start.

{% hint style="warning" %}
**Important:** We recommend that you revoke the metadata authority when everything is ready, because the metadata in Sui tokens also controls the name and symbol of your token!
