dYdX Review: Its Own Chain Against Hyperliquid's Liquidity
dYdX built its own Cosmos chain to escape shared infrastructure, then watched Hyperliquid pull ahead on volume and market count. We traded on both to see what dYdX still does better.
Our verdict
dYdX v4 delivers what it promised when it left shared infrastructure for its own Cosmos chain: full decentralization of the order book, maker rebates for stakers, and open governance through the dYdX Foundation. What it has not delivered is the liquidity to match. Hyperliquid runs somewhere between ten and twenty times dYdX's daily volume and lists roughly 50 more markets, and two chain halts in 2024 and 2025 dented confidence that a self-run chain can stay up under stress. dYdX remains a legitimate choice for a trader who values decentralization over depth, but Hyperliquid is the better execution venue for most others right now.
Best for: Traders who prioritize a fully decentralized, self-custodied order book over the deepest liquidity
Why dYdX built its own chain
dYdX made a bet that most protocols never take: it left a shared order book model and built its own Cosmos chain, dYdX Chain, so the exchange itself would validate and settle every trade rather than depending on someone else's sequencer. We funded a wallet, traded on the live chain for two weeks, and ran the same trades on Hyperliquid to see what that independence actually costs a trader in fees, fills and uptime. The comparison matters because both platforms now market themselves the same way, as the professional home for onchain perpetuals, and only one of the two claims can be true for a given trader depending on what they actually need from a venue.
Fees look competitive on paper
dYdX advertises maker fees from 0.01%, with rebates that can reach zero for stakers trading at volume, and taker fees around 0.05%. Hyperliquid's base tier runs 0.015% maker and 0.045% taker, with its own volume-based discounts. Head to head the two are close enough that fees alone will not decide which platform to use; the gap that actually matters shows up in market depth, not the rate sheet.
Liquidity is where the gap opens
This is where the comparison stops being close. Hyperliquid clears somewhere between $8 billion and $12 billion in daily perpetual volume with roughly $9 billion in open interest, against dYdX's $400 million to $700 million in daily volume and under $500 million in open interest. Hyperliquid lists over 300 markets to dYdX's roughly 200 to 250, and DeFiLlama puts Hyperliquid's TVL near $5 billion against dYdX's $350 million, a tenfold difference. We felt that gap directly: a mid-size order on a less common dYdX market moved the price noticeably more than the identical order on Hyperliquid, which is exactly what thinner order books do.
