Non-Custodial Order Books: How Hyperliquid, dYdX and Lighter Differ

Three credible non-custodial order-book exchanges run on three different architectures. Here is how their performance, security and decentralisation trade off.

The case that 'centralised exchanges always have better UX and decentralised exchanges always have weaker UX' was decisively broken in 2024-2025 by a wave of high-performance non-custodial order-book venues. Three of them — Hyperliquid, dYdX v4, and Lighter — reached meaningful volume on three different architectural bets. Comparing them tells you a lot about where on-chain perpetuals are heading.

Choosing Between Them

Steyble Perps Routing

Steyble Perps routes user orders to whichever non-custodial venue has the best combination of price, depth, and latency for the requested instrument — typically Hyperliquid for majors, with Lighter and dYdX picked for specific instruments where they offer better liquidity. The user sees a single self-custodial perps surface that hides the venue selection complexity, which is the right separation between user experience and the underlying infrastructure layer.

What These Three Venues Share

What to Watch Going Forward

Two trends will shape this category through 2027. First: order-book matching latency continues to compress, with sub-50ms becoming the new baseline; this favours venues with custom L1 architecture (Hyperliquid) over those running on shared chains. Second: regulatory scrutiny on perpetuals — particularly in the US — will likely force venue redomiciling, and the venues that adopted clean self-custody postures earliest will face the lightest friction. Watch the venue's geographic footprint and licensing posture as carefully as you watch its trading metrics.
