What Is Token Metadata?
Token metadata includes name, symbol, logo, and description. Learn how Solana token metadata works with the Metaplex standard.
What is Token Metadata?
Token metadata on Solana includes human-readable information about a token: its name, symbol (ticker), description, logo image, and external links. This data is stored using the Metaplex metadata standard.
Metadata Components
- Full display name (e.g., "My Token")
- Ticker symbol (e.g., "MTK")
- Link to JSON file with description, image, and attributes
- Logo displayed in wallets and DEXs
- About text for the token
- Project website link
How Metadata Is Stored
Metadata is stored in an on-chain metadata account that points to a JSON file hosted on decentralized storage (Arweave or IPFS). Wallets, explorers, and DEX interfaces read this metadata to display token information.
Mutable vs. Immutable Metadata
Every token is created with update authority intact by default — there's no toggle to make metadata immutable at creation. While update authority is held, a Metaplex-compatible tool can still change the name, symbol, logo, and description. Revoking update authority makes the metadata permanently immutable — locked for good, for anyone, with no way to undo it. On SolTokenCreator.io, revoking update authority costs 0.1 SOL, the same fee and same one-way action as revoking mint or freeze authority.
