Episode notes
Phoenix Spot Launched Amid A 19-Hour Outage
- Early Phoenix Spot testing hit a 19-hour Solana outage, forcing product designs to assume downtime risk.
- That fragility in 2022 shaped Ellipsis's move toward more resilient liquidity architectures.
The Sequencer Router Liquidity Pipeline Limits Routing
- On-chain trades pass through sequencer, router, then liquidity, which constrains optimal routing because routes must be set before execution.
- Phoenix focused on liquidity primitives (prop-AMM style) because sequencing and routing were out of their control.
Ship Perps Before MCP Arrives
- Build now rather than wait for MCP because sequencing issues only bite at scale and early product-market fit requires assets, users, and liquidity parity.
- Use MCP as a future improvement path, not a precondition for shipping.
