The Problem
Centralized perp exchanges require trusting an operator with user funds and offer a narrow asset menu; on-chain perp DEXes typically have weak UX, limited markets, and high latency.
The Solution
Extended pairs a CEX-grade matching engine and 100+ markets (crypto, equities, FX, commodities) with self-custodial StarkEx settlement on Starknet — users keep custody while trading with up to 100x leverage and CEX-level fees.
Why it Matters
