Oct 17, 2025 Kain Warwick, founder of Synthetix and Infinex, dives into his latest venture: a perpetuals DEX on Ethereum's mainnet. He explains the rationale behind this contrarian move and details his hybrid optimistic order book model. Kain discusses the challenges of operating on Layer 1, including gas costs and liquidations, while envisioning a future where DeFi can outcompete centralized exchanges.

Episode notes
Tradeoffs Of A Centralized Matcher
- Using a centralized off-chain matcher yields speed but sacrifices full permissionlessness; you can later decentralize the sequencer.
- Traders mostly care that their orders get filled fast; on-chain margin finality matters less to them in the short term.
Transparency With Selective Opacity
- Full transparency on orders will only show orders that are in the on-chain book; off-book limit orders remain opaque.
- Synthetix views privacy for standing orders as a feature to prevent stop-hunting, and will iterate based on trader feedback.
Plan For Congestion And Target Big Traders
- Prepare escape hatches for congestion by allowing alternative margin deposit paths (e.g., L2s) and letting matching engines read both.
- Target large traders initially who value reduced counterparty and bridging risk over low gas costs.
