Pyth Network Concepts

Price Feed IDs

Each asset has a unique 32-byte hex identifier (e.g., 0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace for ETH/USD). The node accepts both symbols (ETH/USD) and raw feed IDs.

Price Format

Pyth prices use integer representation with an exponent:

• price: Integer value
• expo: Exponent (typically negative, e.g., -8)
• Actual price = price * 10^expo

Confidence Intervals

Every price includes a confidence interval representing uncertainty:

• Excellent: < 0.1% of price
• Good: < 0.5% of price
• Acceptable: < 1% of price
• Caution: > 1% of price

Pull Oracle Model

Unlike push oracles, Pyth uses a pull model where users fetch price updates from Hermes and submit them on-chain when needed.

VAA (Verified Action Approval)

Wormhole-signed messages that attest to price data for cross-chain updates, enabling trustless price verification.

Supported Price Feeds

Cryptocurrencies

BTC/USD, ETH/USD, SOL/USD, BNB/USD, XRP/USD, ADA/USD, DOGE/USD, AVAX/USD, DOT/USD, LINK/USD, UNI/USD, ATOM/USD, ARB/USD, OP/USD, SUI/USD, APT/USD, and more...

Error Handling

The node includes comprehensive error handling:

• Invalid feed ID validation
• Stale price detection
• Network connectivity issues
• Rate limit handling
• On-chain transaction failures

Security Best Practices

1. Never expose private keys - Use n8n credentials securely
2. Check confidence intervals - Don't use prices with high uncertainty
3. Test on testnet first - Use testnet before mainnet operations
4. Monitor price staleness - Verify prices are fresh before use
5. Validate feed IDs - Ensure correct feed IDs for your assets
