# Pyth Oracle

Uniocean uses **Pyth Network** as its sole oracle for settlement prices, ensuring independence and verifiability.

## What Is Pyth Network?

Pyth is a decentralized oracle network that aggregates real-time price data from 15+ major exchanges and institutional trading firms. Data providers include Binance, Coinbase, Kraken, Jump Trading, and other major market makers.

## Why Pyth?

| Property                  | Benefit for Uniocean                              |
| ------------------------- | ------------------------------------------------- |
| Decentralized             | No single source of failure                       |
| High frequency            | Sub-second price updates for accurate settlement  |
| Cryptographic attestation | Prices come with verifiable proofs (VAAs)         |
| Broad coverage            | Supports crypto, forex, commodities, and equities |
| Independent               | Platform cannot influence or manipulate prices    |

## How It Works in Uniocean

### During Live Markets

Real-time price data from Pyth feeds directly into the rankings system, updating positions every second as prices move.

### At Settlement

When a market closes:

1. The settlement system requests a Verifiable Attestation (VAA) from Pyth for the exact close timestamp
2. The VAA proves the price was genuinely recorded by Pyth at that time
3. The VAA is included in the on-chain settlement transaction as cryptographic proof
4. Anyone can verify the price attestation independently

## Oracle Independence

The platform has no ability to:

* Choose which price to use
* Adjust the settlement price
* Delay price reporting
* Select a favorable timestamp

The settlement price is determined entirely by Pyth Network's aggregated feed at the market's predetermined close time.

## Live Price Charts

The TradingView-powered charts on market pages display real-time Pyth price data. Users see the same price feed that will determine their final ranking, providing complete visibility during live markets.

## Verification

Users can independently verify any settlement price by:

1. Checking the Pyth explorer for the asset pair at the settlement timestamp
2. Comparing against the price recorded in the on-chain settlement event
3. Validating the VAA signature against Pyth's known public keys
