Plain-language glossary
Oracle: A system that provides data for applications to use. Mimir focuses on price data derived from onchain liquidity.
Feed: An identified price reference with a defined configuration and changing observations.
Source Feed: A reference for one asset pair, derived from its configured liquidity sources.
Composite Feed: A reference formed by adding component prices multiplied by chosen quantities.
Base / quote: In MRVL/USDC, MRVL is the asset being priced and USDC is the unit used to express its price.
Mint: The Solana address identifying a token. Different tokens can use the same displayed ticker.
Feed ticker: A short, unique identifier for a Mimir feed, useful for recognizing it in the terminal. Source and Composite Feeds share this namespace. A feed ticker is separate from an underlying token's symbol. Choose a ticker.
Pool: Onchain liquidity used for trading assets; a possible input to a Source Feed.
Adapter: Code that understands and validates a particular pool format.
Refresh: An onchain operation that calculates and records updated feed data. An application can refresh a feed and consume its price in the same transaction. A simple RPC read only retrieves stored data.
Shadow: Mimir's offchain pricing mode for explorers, terminals and other interfaces. It calculates prices without sending a refresh transaction or changing the feed's stored onchain observation. Explore Shadow.
Snapshot: A stored observation and the metadata needed to interpret its state and validity.
Slot: A unit in Solana's progress. Protocol validity windows can be expressed in slots rather than wall-clock seconds.
TWAP: Time-weighted average price: a price measure across a period, rather than just one point. Availability and requirements depend on the feed and consumer.
Lamport: The smallest unit of SOL. One SOL is one billion lamports.
Fee vault: The account that holds a feed's collected fees until the claim path distributes them.
RWA / tokenized equity: A token linked to an offchain asset or instrument. Its issuer's terms determine its rights; the name alone does not.
Perpetual market: A derivatives market without a fixed expiry. Its oracle input is one part of a larger trading and risk system.
