Crate stork_solana_sdk 

This is a Rust SDK to build Solana programs that consume Stork price feeds. This crate is maintained by Stork Labs.

A top level overview, as well as a small code sample, can be found in the libraries entry in crates.io.

Pull Model

The Stork Solana SDK allows users to consume Stork price updates on a pull basis. This puts the responsibility of submitting the price updates on-chain to the user whenever they want to interact with an app that consumes Stork price feeds. Stork Labs maintains a Chain Pusher in order to do this.

Stork Price Feed Accounts

On Solana, Stork price feeds exist as on-chain accounts. These accounts are instances of the TemporalNumericValueFeed account struct, and are created and owned by the Stork Oracle contract. These account have an ID which associates them with a specific asset, and a latest_value field which stores the latest price update. The ID of a TemporalNumericValueFeed account is determined by taking the keccak256 hash of the asset ID. The latest_value field is an instance of the TemporalNumericValue struct, which holds the quantized price, and a unix timestamp indicating when the price was created.

Anchor

The Stork Solana SDK is built on top of Anchor, a framework for building Solana programs.
