Metaplex — Solana Token GuidesMetaplex is the protocol that handles token metadata on Solana — the name, symbol, image URI, description, and external links that the SPL Token Program itself does not store. Every wallet, aggregator, and explorer (Phantom, Jupiter, Solscan, DexScreener, Birdeye) reads the [Metaplex Token Metadata account](https://developers.metaplex.com/token-metadata) to display your token's branding. The articles below cover the metadata account structure, the 32-character name limit and 10-character symbol limit, how to pin images to IPFS so they don't 404 in six months, update authority semantics (and why revoking it is permanent), and the Token-2022 extensions that change parts of the metadata model.

How these Metaplex guides connect
New to launching on Solana? Start with How to Create a Solana SPL Token for the end-to-end walkthrough, work through the Solana memecoin launch checklist, then come back to the metaplex guides above for the detail on this specific step.
