Metadata Extension (Token-2022)
A Token-2022 extension that stores token name, symbol, and URI directly on-chain.
Definition
The Metadata extension is a Token-2022 feature that allows token creators to store metadata — including token name, symbol, and URI pointing to an image or JSON file — directly within the token mint account on-chain.
Previously, token metadata on Solana required a separate Metaplex metadata account. The Token-2022 Metadata extension internalises this, simplifying the token creation process and reducing the number of accounts needed.
On-chain metadata is immutable if the metadata authority is revoked. Mutable metadata (where the authority is retained) allows updates to the token name, symbol, and URI — which is a risk consideration similar to other active authorities.
StakePoint & Metadata Extension (Token-2022)
StakePoint displays token metadata — names, symbols, and logos — sourced from on-chain metadata and external APIs. Tokens using the Token-2022 Metadata extension have their information stored natively on-chain.
