Oracle Price Submitter & Keeper (Rust)

A high-performance price oracle system that fetches real-time token prices from Pyth Network and stores them in a PostgreSQL database using SeaORM. This system combines the functionality of the original Price Submitter and Pricing Keeper.

📦 Architecture Overview

• Language: Rust
• Database: PostgreSQL
• ORM: SeaORM
• Price Source: Pyth Network
• Data Granularity: Supports candle generation for 5m, 15m, 1h, 4h, and 1d intervals.
• Chains Supported:
  • Monad Testnet

⚙️ Features

• Submits price of tokens to DB every 5 seconds.
• Built-in support for token candles over multiple timeframes.
• Uses Pyth price feeds (ideal for tokens not listed on CEX).
• Easily scalable to support new tokens or chains.
• Maintains data indexed by timestamp and chain ID for quick retrieval.
