Perp DEX Showdown: Hyperliquid vs dYdX vs GMX — Which to Choose
CryptoRebateHub Editorial Team
Hyperliquid (0.045%/0.015%) and dYdX (0.05%/0.01%) are on-chain order books; GMX charges 0.04–0.06% against oracle-priced pools plus borrowing fees.
Direct answer: Hyperliquid, dYdX and GMX are three different machines, not three prices for the same product. Hyperliquid runs an on-chain order book on its own L1 with 0.045% taker / 0.015% maker base fees and hourly funding; dYdX runs an order book on its own Cosmos chain with 0.05% taker / 0.01% maker at the entry tier; GMX has no order book and charges 0.04% or 0.06% to open and again to close against oracle-priced pools, plus a variable borrowing fee (all per official docs, checked 2026-11-01). Pick by execution model first and fee second: active traders who need depth lean to the order books, long-tail or pool-side users to GMX.
Three models, three sets of trade-offs
| Hyperliquid | dYdX (v4 / dYdX Chain) | GMX (V2) | |
|---|---|---|---|
| Pricing | On-chain central limit order book | On-chain order book, off-chain matching by validators | Oracle price against multi-asset liquidity pools (GM pools) |
| Runtime | Own L1 (HyperBFT consensus) | Own Cosmos app-chain | Arbitrum and Avalanche settlement; other chains via GMX Account |
| Counterparty | Other traders; HLP vault as a market maker | Other traders | The pool's liquidity providers |
| Gas to trade | None; gas only on deposit (docs, checked 2026-11-01) | None; "traders would not pay gas fees to trade" (help centre, checked 2026-11-01) | Execution fee paid to the keeper in ETH, AVAX or USDC, overestimated and refunded (docs, checked 2026-11-01) |
| Funding | Hourly, capped at 4% per hour | Per-contract funding | Variable funding plus a borrowing fee that the heavier side pays |
| Fee governance | Protocol schedule; fees go to HLP, assistance fund and deployers | Adjustable by governance proposal | Protocol parameters |
The order-book venues feel like a centralised exchange: limit orders, maker and taker roles, depth you can see. GMX replaces all of that with a pool that takes the other side of every trade at an oracle price, which is why it can list assets with no natural market makers and why its costs show up as fees and price-impact rules rather than as spread.
Fees side by side, with a 10,000 USD round trip
| Cost line (checked 2026-11-01) | Hyperliquid | dYdX | GMX V2 |
|---|---|---|---|
| Entry-tier taker | 0.045% | 0.05% (under 1M USD 30-day volume) | 0.06% to open if the trade worsens long/short balance, 0.04% if it improves it |
| Entry-tier maker | 0.015% | 0.01% | Same schedule; no maker/taker distinction |
| Best published tier | 0.024% taker / 0% maker above 7B USD 14-day weighted volume | 0.025% taker / −0.011% maker at 200M USD or more 30-day volume | Not volume-tiered |
| Volume window | Rolling 14 days, spot counted double | Trailing 30 days | n/a |
| Holding costs | Hourly funding | Funding | Funding plus borrowing fee, both variable and shown in the interface |
| Discounts | 4% referral discount on first 25M USD volume; HYPE staking 5% to 40% | Governance-set rebates | None stated |
| 10,000 USD open and close as taker | 9.00 USD | 10.00 USD | 8.00 to 12.00 USD plus execution fee |
| 10,000 USD open and close as maker | 3.00 USD | 2.00 USD | n/a |
| Liquidation fee | Per margin tier | Per contract | 0.2% to 0.45% of position by market type |
Two observations. The order-book venues are within a basis point of each other on taker fees, and both reward makers heavily: dYdX publishes a negative maker fee at its top tier and Hyperliquid pays maker rebates of up to −0.003% to accounts above 3% of maker volume (checked 2026-11-01). On GMX the headline fee can be the lower 0.04% if your trade balances the pool, but you also pay a borrowing fee for as long as the position is open and bear price impact on the way out, so a multi-day GMX position is rarely cheaper than the order books. Compare your own expected hold with the funding rates tool and read how to read funding rates before assuming anything about carry.
For Hyperliquid specifically, the Hyperliquid fees guide breaks down tiers, staking and the referral discount; our Hyperliquid referral page lists the site code HYPEKR, which applies the 4% discount per Hyperliquid's referral docs (checked 2026-11-01).
Step-by-step: choosing and starting safely
- Decide what you trade. Major pairs with size and limit orders point to Hyperliquid or dYdX; long-tail assets or a desire to earn fees as a liquidity provider point to GMX.
- Check access. All three are self-custody and wallet-based; front ends apply regional restrictions that differ by venue and change over time. Read does Hyperliquid require KYC for the pattern and check each venue's current terms.
- Fund the right chain. Hyperliquid takes USDC on Arbitrum through its deposit window (email logins can also send from Ethereum, Base or Polygon); dYdX uses USDC on its own chain via supported bridges; GMX settles on Arbitrum or Avalanche. Bridging is a cost and a risk line of its own; see cross-chain bridge safety.
- Read the venue's own fee page while logged in. Hyperliquid shows your tier and 14-day volume; dYdX shows your 30-day tier under Portfolio, Fees; GMX shows borrowing and funding rates per market.
- Start small, use limit orders where they exist, and measure slippage with the slippage calculator before scaling.
- Set leverage from your liquidation distance, not from the maximum offered; the leverage and liquidation basics guide covers the arithmetic.
Risks that the fee table does not show
- Leverage on any of them is leverage. The counterparty and the chain differ; the liquidation maths does not.
- Self-custody failures are final. Lost keys, malicious approvals and phishing front ends are the dominant loss cases on every DEX. Work through how to use a DEX safely first.
- Oracle and pool risk on GMX. Pool-priced venues depend on oracle freshness and on the pool's solvency; they have historically been targets for price-manipulation attempts on thin assets. Order-book venues depend instead on market-maker depth, which can vanish in a crash.
- Validator and governance concentration. Hyperliquid's L1 and dYdX's app-chain are run by validator sets far smaller than Ethereum's, and fee schedules, listings and parameters can change by governance or by the core team.
- Bridge dependence. Deposits and withdrawals on all three pass through bridges or cross-chain messaging. Treat bridge limits and pause events as part of your liquidity planning.
- Referral and discount drift. Discounts have volume caps and exclusions; Hyperliquid's does not apply to vaults or sub-accounts (checked 2026-11-01).

FAQ
Which perp DEX has the lowest fees?
Among the three, at entry tiers and as a taker, Hyperliquid's 0.045% is slightly below dYdX's 0.05%, and GMX ranges 0.04% to 0.06% plus a borrowing fee (docs checked 2026-11-01). As a maker dYdX's 0.01% is below Hyperliquid's 0.015%. Holding costs usually decide the total, so model funding and borrowing for your intended hold.
Do I pay gas to trade on these DEXs?
Not per order on Hyperliquid or dYdX; both say trading is gas-free and gas applies to deposits and withdrawals (checked 2026-11-01). GMX charges an execution fee per order that is overestimated and partly refunded.
Is GMX cheaper for long-tail assets?
It is often the only one of the three that lists them. Whether it is cheaper depends on the borrowing fee and price impact for that market, which are shown in the GMX interface and change with pool utilisation.
Do any of these require KYC?
Access is by wallet, but each front end applies its own regional and compliance rules, which can change. Check the venue's current terms rather than relying on a general claim.
Can I use the HYPEKR code on dYdX or GMX?
No. It is a Hyperliquid referral code only and gives 4% off Hyperliquid fees on the first 25M USD of volume (checked 2026-11-01).
Bottom line
Choose the execution model before you compare the fee table. Hyperliquid and dYdX give order-book traders CEX-like control with fees within a basis point of each other and strong maker incentives; GMX trades depth and maker pricing for oracle-priced access to assets the order books do not list, at the cost of borrowing fees and price impact. In every case the self-custody, bridge and leverage risks are yours, so start small and read the live fee page before sizing up.
Educational content only, not investment advice. Fee schedules, tiers, funding mechanics, supported chains and regional access on Hyperliquid, dYdX and GMX change; confirm current values in each protocol's official documentation and interface before trading.
