Hyperliquid vs dYdX: what is the difference?

The main difference in Hyperliquid vs dYdX is how each chain handles its order book and fees. Both are perp DEXs built as standalone blockchains, but they made different design choices about what goes onchain and who sets trading costs.

How do Hyperliquid and dYdX work differently?

Hyperliquid's docs describe its state as two parts. HyperCore holds margin and the matching engine, and HyperEVM is the general purpose part of the chain. HyperCore does not rely on off-chain order books. The chain is secured by HyperBFT, a variant of HotStuff consensus, with block production weighted by staked tokens. The docs report a median end-to-end latency of 0.2 seconds for co-located clients and capacity of about 200,000 orders per second. Our guide to what Hyperliquid is has more background.

The dYdX Chain is built with the Cosmos SDK on CometBFT proof-of-stake consensus. Validators store orders in an in-memory book that is not committed to consensus and gossip them to other nodes. When a validator proposes a block, matched trades go into it, and the block is committed once at least two thirds of stake approves. A separate read-only Indexer serves data to traders.

What are the Hyperliquid vs dYdX fees?

As of November 2026, Hyperliquid's base perp tier charges 0.045% for takers and 0.015% for makers. Rates fall across six higher tiers based on rolling 14-day volume, with spot volume counting double. Staking HYPE adds discounts from 5% up to 40%. Hyperliquid says fees go to the community, including its HLP vault and an assistance fund that converts fees to HYPE and burns it.

dYdX uses a maker-taker model where taker fees depend on trailing 30-day volume across all perpetual markets. The Help Center says there are no gas fees by default, cancelled orders are free, and fees go to validators, who may share them with stakers. Fee tiers are a governance parameter that the community can change by proposal, and traders can see their current tier in the app.

Which perp DEX is more decentralized?

Both describe themselves as decentralized, but in different ways. Hyperliquid stresses that its trading state passes through HyperBFT in one consistent transaction order. dYdX keeps its order book out of consensus and records only the results onchain. The dYdX docs also note that its open-source software is not run by dYdX Trading Inc. Which trade-off matters more depends on what a user values, and neither model removes the core risks of trading futures with leverage.
