Logo & metadata — how MintLab does it

MintLab is built so you never host token artwork or descriptions on your own servers. You fill the form: name, symbol, supply, decimals, network, an optional description, and a required logo file. When you create the token, MintLab packages that information, stores it permanently, and wires it to your mint so wallets and explorers can show your brand.

What you upload

Token Logo (required)

• Formats: PNG, JPG, or GIF
• Maximum size: 2MB
• Use a square or nearly square image for the cleanest look in wallets

Token Description (optional)

A short text field on the form. Leave it blank if you only need a name, symbol, and image.

Fees and storage

Permanent storage for your logo and the generated metadata bundle is included in MintLab’s estimate — about 0.010 SOL on top of the deploy line items, for a typical total around 0.024 SOL before optional revoke options. It is a one-time charge; MintLab does not bill you monthly for that storage.

Preview

The Token Preview panel on the home page updates as you type and when you pick a logo, so you can confirm name, symbol, supply, decimals, network, description, and image before you mint.

Technical deep dive (optional)

Behind the scenes, MintLab follows the usual Solana token-metadata conventions: it builds a small structured document (industry-standard JSON) that lists your name, symbol, description, and image, uploads the image and that document to Arweave for permanent retention, then registers the document’s HTTPS address on-chain so apps know where to fetch it. You do not copy or paste that address — the product handles it end to end.

If you use the Solana CLI yourself, the final step is still conceptually “attach name, symbol, and the metadata location to the mint”; MintLab automates the upload and hands you the right values when integration is complete.
