GMX:
the DEX that pioneered "real yield" perps, honestly overtaken by faster-moving competitors.
We tore apart GMX, live on Arbitrum and Avalanche since September 2021, across the same seven-category scorecard we've used throughout this series. From a genuinely distinctive oracle-based execution model with zero price impact on standard orders, one of the most extensive, longest-running audit programs we've found in this series (Guardian alone logged 88 person-weeks and 365 findings across just its first eight engagements), and a genuinely substantive architectural response to its own past failure, to a real, confirmed $42 million exploit in July 2025 that sat undetected in previously-audited V1 code for years, and an honest, precisely quantified competitive decline worth centering directly: Hyperliquid now processes roughly $245 billion in 30-day volume against GMX's $2.8 billion as of mid-2026, a gap multiple independent sources describe as GMX no longer being the obvious first stop for active perp traders; and landed on a score the marketing page won't show you.
Our take, up front: GMX, founded in 2021 by an anonymous team, helped define the "real yield" perp DEX category: rather than an order book or a classic AMM, trades execute directly against an oracle price, with zero price impact on standard-sized orders regardless of pool depth. Real, genuinely extensive, long-running, multi-firm, well-documented audit program: Guardian as primary auditor, with eight engagements between October 2022 and September 2023 alone totaling 88 person-weeks and 365 findings remediated or acknowledged, plus continuing audits through 2024, 2025, and 2026, alongside ABDK, Certora, Dedaub, and Sherlock, backed by an active bug bounty. Real, genuinely distinctive liquidity design: V1's GLP was a single multi-asset basket backing every trade, with liquidity providers earning 70% of fees while effectively taking the other side of traders' positions; GMX now treats V1 as legacy in favor of V2's structurally different, isolated GM pools. Real, genuinely distinctive expansion beyond crypto: gold and silver synthetic perpetuals, live 24/7 and priced via Chainlink Data Streams. What we can't set aside: a real, confirmed incident. On July 9, 2025, GMX V1 was exploited for more than $42 million via a reentrancy technique targeting vault accounting and GLP token pricing on Arbitrum, a flaw one security firm traced to how V1 booked the average price of short positions, sitting quietly in the code for years despite prior audits, a genuinely honest reminder that an audit is a snapshot, not a permanent guarantee. Real, genuinely positive incident response: the attacker was offered a white-hat bounty, GMX completed distribution to affected Arbitrum GLP users, and V2 was confirmed unaffected. And real, honest, precisely quantified competitive decline worth centering directly rather than softening: Hyperliquid now processes roughly $245 billion in 30-day volume against GMX's $2.8 billion as of mid-2026, and at least one detailed source states plainly that GMX is no longer the obvious first stop for active perp traders. We weighted all of it below.

What we can't set aside: a real, confirmed incident. On July 9, 2025, GMX V1 was exploited for more than $42 million via a reentrancy technique targeting vault accounting and GLP token pricing on Arbitrum, a flaw one security firm traced to how V1 booked the average price of short positions, sitting quietly in the code for years despite prior audits, a genuinely honest reminder that an audit is a snapshot, not a permanent guarantee. Real, genuinely positive incident response: the attacker was offered a white-hat bounty, and GMX completed distribution to affected Arbitrum GLP users; V2 and other protocol components were confirmed unaffected. Real, genuinely substantive architectural response: GMX has since made V1 legacy, phasing out its trading since July 2025 and sunsetting its contracts, moving users toward V2's structurally different, isolated GM pools rather than V1's single shared basket.
Pros
- Genuinely extensive, long-running, multi-firm audit program (Guardian, ABDK, Certora, Dedaub, Sherlock)
- Substantive architectural response: V1 sunset, V2 uses structurally safer isolated GM pools
- White-hat bounty offered; affected Arbitrum GLP users compensated
Cons
- Real, confirmed July 2025 exploit: $42M+ via reentrancy in previously-audited V1 code
- Honest reminder that years of prior audits didn't catch the flaw before exploitation
Real, honest, significant competitive decline, precisely quantified: Hyperliquid now processes roughly $245 billion in 30-day volume against GMX's $2.8 billion as of mid-2026, and at least one detailed source states directly that GMX is no longer the obvious first stop for active perp traders. Real, modest current TVL, cited around $261.65 million, and roughly 90,000 total users, both meaningfully smaller than the category's current leaders.
Pros
- Still processes billions in monthly volume; a real, functioning market
Cons
- ~88x smaller 30-day volume than Hyperliquid as of mid-2026
- Modest TVL (~$261.65M) and user count (~90K) relative to category leaders
Real, genuinely non-custodial, self-custodial trading directly from a connected wallet with no KYC required. Real, disclosed, precisely quantified fee split: GMX token holders accrue 30% of platform fees, GLP/GM liquidity providers accrue 70%. Real, an anonymous founding team, though a likely lead developer identity is informally known within the community.
Pros
- Genuinely non-custodial; no KYC required
- Disclosed, transparent, precisely quantified fee-split model (30%/70%)
Cons
- Anonymous founding team, a real, disclosed trust consideration
Real, genuinely broad reach across two independent chain deployments, Arbitrum and Avalanche, which operate independently so an issue on one doesn't affect the other. Real, around 30 perpetual markets focused on major and mid-cap assets, with V2's synthetic markets allowing new assets to be listed without requiring native token liquidity. Real, genuinely distinctive expansion into gold and silver synthetic perpetuals, live 24/7 and priced via Chainlink Data Streams.
Pros
- Independent Arbitrum and Avalanche deployments; isolated risk between chains
- Distinctive gold and silver synthetic perpetuals via Chainlink Data Streams
Cons
- ~30 markets is modest relative to some other DEXs in this series
Real, genuinely distinctive execution guarantee: trades execute at the oracle price with zero slippage regardless of order size on standard trades, a real, structural difference from order-book or AMM-based execution. Real, described as more approachable than its underlying mechanics suggest, with a straightforward connect-bridge-trade flow.
Pros
- Zero price impact on standard-sized orders via oracle-based execution
- Approachable connect-bridge-trade flow despite complex underlying mechanics
Cons
- Understanding GLP/GM liquidity provider risk requires real, genuine effort upfront
Real, genuinely competitive core perpetual fees, dynamically priced around 0.04%-0.06% depending on how a trade impacts pool balance. Real, honest, notable ceiling: atomic spot swaps can cost up to 3.75% in some cases, a real, meaningfully higher cost than the platform's headline perpetual rates.
Pros
- Competitive core perpetual fees (0.04%-0.06%)
- Referral program offers a 10% fee discount for referred traders
Cons
- Atomic spot swaps can cost up to 3.75% in some cases, a real, high ceiling
Real, genuinely distinctive oracle-based, zero-price-impact execution model, structurally different from every other DEX we've reviewed in this series. Real, gold and silver synthetic perpetuals. Real, esGMX escrowed token rewards with a 12-month vesting mechanism.
Pros
- Distinctive oracle-based, zero-price-impact execution model
- Gold and silver synthetic perpetuals; esGMX vesting rewards
Cons
- None significant found in our research

If providing liquidity, understand the GLP/GM counter-party structure fully before depositing; you profit when traders lose, which is a genuinely different risk profile than passive AMM liquidity provision elsewhere in this series.
A genuine pioneer, honestly no longer the category's center of gravity.
GMX deserves real, historical credit: it helped define an entire category of "real yield" perpetual trading built on oracle pricing rather than order books or classic AMMs, and its audit investment is genuinely among the most extensive and longest-running we've found in this series. The July 2025 exploit is real and serious, but GMX's response, sunsetting the flawed V1 architecture entirely rather than patching around it, is a genuinely substantive answer, not a cosmetic one. What we can't soften is the plain, precisely quantified reality of where GMX sits today: an ~88x gap in 30-day volume against Hyperliquid isn't a matter of opinion or vibes, it's a specific, sourced number, and it's the single biggest reason this score lands where it does. GMX remains a real, functioning, reasonably secure platform; it's just no longer the platform most active perp traders would reach for first.
The scorecard above is deliberately general. Whether GMX is right for you depends heavily on which of these you already are.
The trader who specifically wants oracle-based, zero-price-impact execution or gold/silver perpetual exposure
These genuinely distinctive features are the strongest, most differentiated reasons to choose GMX today.
The liquidity provider who understands and accepts the GLP/GM counter-party risk structure
The 70% fee share is real, but it comes with genuinely different risk than passive AMM liquidity provision.
The trader comfortable with a platform that has meaningfully less volume than the category's current leaders
GMX still functions as a real, active market, just at a smaller scale than Hyperliquid specifically.
Active perp traders prioritizing the deepest liquidity and fastest execution above all else
Multiple sources are direct that GMX is no longer the obvious first stop for this specific priority.
The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; the July 2025 exploit timelined precisely, the GMX-vs-Hyperliquid decline quantified directly, fees broken down by product, and GMX against the full field.
The July 2025 exploit, timelined
| Step | What happened |
|---|---|
| Root cause | A reentrancy technique targeted V1's vault accounting and GLP token pricing, exploiting how V1 booked the average price of short positions |
| Amount | More than $42 million, on Arbitrum specifically |
| Scope | V1 and GLP only; V2 and other protocol components confirmed unaffected |
| Response | Attacker offered a white-hat bounty; GMX completed distribution to affected Arbitrum GLP users |
| Architectural fix | V1 trading phased out since July 2025; contracts sunset; V2's isolated GM pools now the main product |
The flaw reportedly sat in previously-audited code for years before being exploited, a genuinely honest reminder that an audit reflects a snapshot in time, not a permanent guarantee.
GMX vs. Hyperliquid, quantified directly
| GMX | Hyperliquid | |
|---|---|---|
| 30-day volume (mid-2026) | ~$2.8 billion | ~$245 billion |
| TVL | ~$261.65 million | ~$5.9 billion |
| Total users | ~90,000 | Not directly comparable |
This isn't a subjective ranking; both figures come from independent, cited sources measuring the same mid-2026 window, and the gap is genuinely large by any measure.
Fees, precisely, by product
| Product | Fee |
|---|---|
| Perpetual trading | ~0.04%-0.06%, dynamic based on pool balance impact |
| Standard spot swaps | ~0.05%-0.07% |
| Atomic spot swaps | Up to ~3.75% in some cases |
| Referral discount | 10% off trading fees for referred traders |
The atomic-swap ceiling is meaningfully higher than the platform's headline perpetual rates; check the specific route and fee before executing a larger spot swap.
GMX against the full field
| GMX | Hyperliquid | Paradex | Lighter | dYdX | |
|---|---|---|---|---|---|
| Since | 2021 | 2023 | 2024 | 2025 | 2017 |
| Execution model | Oracle-priced | Order book (CLOB) | Order book (zk-appchain) | Order book (ZK-rollup) | Order book (validator-distributed) |
| Confirmed security incidents | One ($42M, 2025, V1 only) | None (JELLY was governance) | None found | None found | Two (2024 DNS, 2025 chain halt) |
| 30-day volume (mid-2026) | ~$2.8B | ~$245B | Not directly comparable | ~$1.6T cumulative | Not directly comparable |
GMX's oracle-based execution model remains genuinely distinctive in this comparison; its relative scale, however, has fallen well behind the category's newer and faster-growing platforms.
We don't just want to hand you our number; we want to show you how it sits next to what other review desks and comparison sites have published. We've excluded GMX's own documentation from this comparison, treating it as a primary source rather than an independent review.
Our score lands substantially below the aggregated industry average, one of the largest gaps we've found in this series; most sources treat GMX's declining relevance as competitive-landscape narrative rather than a direct scoring factor, while our methodology weights the Liquidity category heavily enough that the precisely quantified volume gap moves the number substantially.

Yes, once: on July 9, 2025, GMX V1 was exploited for more than $42 million via a reentrancy technique targeting vault accounting and GLP pricing on Arbitrum. V2 and other protocol components were confirmed unaffected, and GMX has since sunset V1 entirely.
Rather than matching orders on a book or pricing through an AMM formula, trades execute directly at the current oracle price, resulting in zero price impact on standard-sized orders regardless of pool depth.
It's a real, functioning platform, but honestly smaller: Hyperliquid processes roughly $245 billion in 30-day volume against GMX's $2.8 billion as of mid-2026, and multiple sources describe GMX as no longer the obvious first stop for active perp traders.
GLP (V1) was a single multi-asset basket backing every trade on the platform; liquidity providers earned 70% of fees but effectively took the other side of trader positions. GM pools (V2) are structurally isolated per-market, a design change made partly in response to V1's exploit.
Perpetual trading runs roughly 0.04%-0.06%, dynamically priced based on how a trade impacts pool balance. Standard spot swaps run 0.05%-0.07%, though atomic swaps can cost up to 3.75% in some cases.
Arbitrum and Avalanche, as two independent deployments; an issue on one chain doesn't affect the other.
Yes, via synthetic XAU/USD and XAG/USD perpetuals, live 24/7 and priced using Chainlink Data Streams, a genuinely distinctive feature for a crypto-native DEX.
An anonymous team founded GMX in 2021. The account "@xdev_10" on X is widely believed to belong to the lead developer, though this hasn't been formally confirmed.
