Oracles

A guide on fetching and interacting with Initia's Enshrined Oracles via Skip Slinky

The Initia L1 has an Enshrined Oracle system powered by Skip Slinky to ensure fresh price data is posted to the chain each block. Slinky is highly performant, tied to the liveness of the chain, and flexible.
