When you create a Solana token, its name, symbol, and logo are stored as on-chain metadata using the Metaplex Token Metadata standard. This data is what wallets and explorers use to display your token correctly.
What is Metaplex Token Metadata?
Metaplex is Solana's standard for on-chain metadata. For SPL tokens, it stores a Metadata Account — a special account derived from your Mint address — that contains:
- Name — Token name (up to 32 characters)
- Symbol — Short ticker (up to 10 characters)
- URI — Link to a JSON file on IPFS containing your logo and description
- Mint Authority — Who can update the metadata
- Is Mutable — Whether metadata can be changed
The Metadata URI
The URI points to a JSON file (stored on IPFS) that follows this standard format:
name— Same as on-chain namesymbol— Same as on-chain symboldescription— Token description (shown on explorers)image— URL to your token logo (PNG/JPG, 512×512 recommended)external_url— Your project website
How Create Solana Token Handles Metadata
When you create a token with our platform, we automatically:
- Upload your logo image to Pinata IPFS for permanent storage
- Create a standard metadata JSON file and upload it to IPFS
- Write a Metadata Account on-chain using Metaplex's
CreateMetadataAccountV3instruction - The result: your token name, symbol, and logo appear in Phantom, Solflare, Solscan and all Solana explorers
Updating Metadata
If you kept Mint Authority enabled, you can update your token metadata later. You'll need to upload a new metadata JSON to IPFS and call the UpdateMetadataAccount instruction with the new URI.
