An integrator who has switch to the new Metis binary observed a 2x improvement in p99 quote latency. Let us know what you'd like to see in future releases.
What you see is NOT what you get when you swap onchain. The app, wallet simulation, and actual execution all diverge. We designed Metis v8 to minimize drift through faster quoting, slippage-aware market selection, onchain split optimization, and next-slot transaction landing.
