Introducing Pyth on Fogo

Pyth Overview
In decentralized finance, protocols need accurate and up-to-date market prices to work safely.
Pyth brings first-party market data on-chain with sub-second latency and a large network of publishers and chains.
Current Pyth Network Snapshot
- $67B total volume relayed
- 125 publishers onboarded
- 2,150 price feeds (active + coming soon)
- 101 active chains
- Trusted by 250+ protocols
What is Pyth?
Pyth is an oracle network focused on low-latency, high-fidelity market data for smart contracts.
You get:
- First-party signed prices from exchanges and trading firms
- Aggregate price + confidence interval per asset
- Consistent feeds across many chains
- A pull-based update model for cost control
How it Works
- Publishers send signed prices to the Pythnet appchain.
- Pyth aggregates and verifies them
- Protocols pull the latest update when needed (~400ms core cadence)
- Prices + confidence intervals are written on-chain
Why pull matters: Fetch data only when your logic needs it, cut gas costs,
and align oracle updates with liquidation and risk checks.
Pyth Lazer
Lazer is Pyth’s high-performance channel for latency-sensitive apps like CLOBs and perps.
- ≈1ms real-time channel
- Fixed-rate channels at 50ms & 200ms
- Customizable payloads: bid/ask, market depth, more
- Lighter proofs (~100 bytes) for faster verification
- Specialized, permissioned integration for institutions
Core vs Lazer: Core offers decentralized ~400ms updates with confidence,
while Lazer provides ultra-low latency, configurable data.
Pull vs. Push Oracles
Pull Oracles (Pyth’s design)
- Updates are requested on-demand.
- Reduces unnecessary on-chain transactions → lower gas costs.
- Supports high-frequency updates (~400ms).
- Provides fresher, more accurate prices during congestion.
- Ideal for arbitrage and speed-sensitive trading.
Push Oracles (Traditional)
- Continuous updates at fixed intervals, even if not needed.
- Higher gas costs due to constant writes.
- More latency under network congestion.
- Limited scalability during high activity.
- Less reliable in volatile markets.
Express Relay (PER)
Express Relay is a priority-auction system that eliminates MEV and links protocols to searchers & liquidators.
- Protocols define valuable operations
- Searchers bid off-chain
- Winning bids forwarded on-chain
- Revenue shared with protocols
Case study – xStocks RFQ
Tokenized equities like AAPLx, TSLAx, METAx trade 24/7 on-chain.
With Pyth Express Relay, market makers quote exact RFQ prices, avoiding slippage and front-running.

Entropy (Randomness)
Entropy provides cryptographically secure, on-chain randomness with real-time generation & multi-chain support.
- Fair NFT mints & raffles
- Games with responsive randomness
- Governance draws & randomized selections
Why Pyth on Fogo?
Traditional chains struggle with the latency and throughput needed for serious markets.
Fogo’s high-performance design pairs perfectly with Pyth’s stack.
- Sub-second data and ms-level Lazer channels match Fogo’s speed
- Confidence intervals improve liquidation safety
- Express Relay recaptures MEV for protocols
- Entropy unlocks fair games and consumer apps
- Large publisher & asset coverage from day one
In Summary
Pyth provides the data backbone for Fogo’s DeFi stack:
- Core feeds for accurate pricing
- Lazer for ultra-low latency trading
- Express Relay for fair execution & MEV control
- Entropy for secure randomness
