3️⃣Metadata
Features available in Metadata section in 20lab token generator for SPL tokens.
Token logo
Your metadata can contain extensive information about your token, with the token logo being one of the most important visual elements. You can easily add a logo using our generator, and both the uploaded image file and all metadata are securely stored on IPFS where they cannot be removed.
IPFS Storage Benefits
Permanent storage: Your logo and metadata cannot be deleted or lost
Decentralized hosting: No single point of failure
Cost efficiency: Saves on Solana fees by storing data off-chain
Global accessibility: Available worldwide through IPFS network
Technical Requirements
Maximum size: 1 MB
Supported formats: PNG, JPG, or WEBP
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.
What to Include
Project purpose: Clearly explain what your token does
Use cases: Describe how people can use your token
Unique features: Highlight what makes your project special
Community information: Include relevant community details
Utility explanation: Explain the token's role in your ecosystem
Website & Social links
Add important links to your project that will be publicly included in the metadata file. These links help users find more information about your project and connect with your community.
Essential Links to Consider
Official website: Your main project website or landing page
Documentation: Links to technical docs or whitepapers
Social media: Twitter, Discord, Telegram, or other community platforms
GitHub repository: For open-source projects or technical transparency
Medium/Blog: For project updates and announcements
Immutable metadata
In the 20lab generator, the metadata update authority is assigned to your deployer address by default. This allows you to correct mistakes or update information later through the token owner dashboard. However, if you're confident everything is correct, you can revoke the metadata update authority by setting it as immutable from the start.
Important: We recommend that you revoke the metadata update authority when everything is ready, because the metadata in SPL tokens also controls the name and symbol of your token!
