This is our independent GMX Review (2026). Can the pool-based perpetual model compete against orderbook DEXs like Hyperliquid? Is the 22% staking APR sustainable? And should you provide liquidity to GM pools or trade elsewhere?
⚠️ Security Notice (July 2025): GMX V1 suffered a $42M exploit in July 2025 due to a reentrancy vulnerability in GLP pool contracts. The attacker returned the funds after accepting a $5M white-hat bounty, and V2 contracts were unaffected. We've updated this review to reflect this incident.
Summary of this GMX review: GMX offers a fundamentally different perpetual trading model: instead of matching orders, you trade against liquidity pools at oracle prices. This means zero slippage on the quoted price — a $10 million trade executes at the same price as a $1,000 trade. With 739,000+ traders across 7 chains (including new Solana deployment), GMX has proven the model works at scale.
The yield opportunities remain attractive: 22.23% APR for GMX stakers and 10.33% for GLV vault depositors. These are real yields from protocol fees, not inflationary token emissions. For yield farmers seeking sustainable returns, GMX delivers.
The main risks are oracle dependency and the July 2025 security incident. GMX relies entirely on Chainlink price feeds, and the 2022 Avalanche incident showed that oracle manipulation can drain LP funds. The July 2025 V1 exploit (funds recovered) demonstrated that even audited contracts can have vulnerabilities. The fundamental model also means liquidity providers are short trader PnL — when traders win consistently, LPs lose.
For most perpetual traders in 2026, Hyperliquid offers better pricing on major pairs. But GMX serves traders who need guaranteed execution without slippage concerns, yield farmers chasing real APR, and multi-chain users wanting perps on Solana or BNB Chain.
GMX Review - Introduction
GMX launched in September 2021 on Arbitrum, pioneering the pool-based perpetual trading model. Instead of orderbooks, traders execute against liquidity pools (originally GLP, now GM pools) at prices sourced from Chainlink oracles. The protocol has since expanded to 7 chains and processed $345B+ in lifetime trading volume.

Who is GMX for? Traders who want guaranteed execution at oracle prices without slippage. Yield farmers seeking sustainable APR from protocol fees (not emissions). Multi-chain users who want perpetuals on Solana, BNB Chain, or Base. Large traders who need to execute without moving the price.
Who is GMX NOT for? Traders prioritizing lowest fees — Hyperliquid is cheaper. Those wanting orderbook dynamics and price discovery. Risk-averse LPs who don't want exposure to trader counterparty risk.
GMX Review - How It Works
GMX uses a unique pool-based model that differs fundamentally from orderbook exchanges.
Oracle-Priced Trading
Instead of matching buy and sell orders, GMX trades are executed against liquidity pools at Chainlink oracle prices:
- No slippage: Your trade executes at the oracle price regardless of size
- Guaranteed liquidity: As long as the pool has assets, your trade executes
- Price impact: Minimal — determined by pool utilization, not order size
This means a $10 million BTC long executes at essentially the same price as a $1,000 position — a major advantage for large traders.
GM Pools and GLV Vaults
GMX v2 introduced isolated GM (GMX Market) pools:
- GM Pools: Single-market liquidity pools (e.g., BTC/USD, ETH/USD)
- GLV Vaults: Auto-managed vaults that distribute across multiple GM pools
- LP Returns: Fees from trades, liquidations, and borrowing costs
The LP Trade-off: Liquidity providers are essentially selling options to traders. When traders profit, LPs lose (and vice versa). This means:
- High APR when traders lose (common in volatile markets)
- Potential losses when traders are consistently profitable
- Oracle accuracy is critical — manipulation can drain pools
Chainlink Data Streams
GMX uses Chainlink Data Streams — sub-second price feeds optimized for perpetual DEXs:
- Speed: Faster than standard oracles
- Accuracy: Aggregated from multiple sources
- Custom: Tailored for GMX's execution model
This reduces (but doesn't eliminate) the oracle manipulation risk that affected GMX in 2022.
Multi-Chain Deployment
GMX now operates on 7 chains:
- Arbitrum — Original and largest deployment
- Avalanche — Second major deployment
- Base — Coinbase L2
- BNB Chain — Binance ecosystem
- Ethereum — Mainnet (December 2025 launch)
- Solana — March 2025 expansion
- Botanix — Bitcoin L2
Each deployment has independent liquidity pools, so depth varies by chain.
GMX Review - Fees: How Expensive is GMX?
| Fee Type | GMX | Hyperliquid | dYdX |
| Taker Fee | 5-7 bps | 3.5 bps | 5-30 bps |
| Maker Fee | 2-5 bps | 1 bps rebate | 0-2 bps rebate |
| Position Fee | 0.1% open/close | N/A | N/A |
| Borrow Fee | Variable (hourly) | Funding rate | Funding rate |
GMX Fee Structure:
- Open/Close Position: ~0.05-0.07% of position size
- Borrow Fee: Paid hourly based on pool utilization
- Swap Fee: 0.2-0.8% for collateral swaps
VIP Tiers: Higher 30-day volume reduces fees:
- Tier 1 (< $1M): 0.020% maker, 0.050% taker
- Higher tiers: Progressive discounts
- Top tier: 0% maker fees
Real Cost Example: On a $10,000 BTC perpetual position:
- GMX (5 bps): $5 fee + borrow costs
- Hyperliquid (3.5 bps): $3.50 fee
- dYdX (Feb promo): $0 fee
GMX isn't the cheapest, but the zero-slippage execution can save money on large orders where orderbook DEXs would have price impact.
Fee Distribution
- 70% to liquidity providers (GM pools)
- 30% to GMX stakers
This creates the 22.23% APR for stakers and 10-20%+ APR for LPs, depending on trading activity.
GMX Review - Security
July 2025 Security Incident
⚠️ On July 9, 2025, GMX V1 was exploited for $42 million.
Attackers exploited a reentrancy vulnerability in the V1 GLP pool contracts, draining USDC, ETH, and other assets. The incident affected V1 only — V2 contracts (GM pools, GLV vaults) were not impacted.
Timeline:
- July 9: Exploit discovered, V1 trading halted immediately
- July 10: GMX offered 10% white-hat bounty ($4.2M)
- July 11: Negotiations resulted in $5M bounty acceptance
- July 12: Attacker began returning funds
- July 15: Bulk of funds recovered to GLP holders
What this means for users: The exploit was in V1 legacy contracts that most users have migrated away from. V2 (GM/GLV) was unaffected and continues to operate. The fund recovery was successful, but the incident revealed that even audited contracts can have vulnerabilities.
Protocol Security Measures
GMX security measures include:
- Audits: Multiple audits from leading firms (though V1 was audited and still exploited)
- Bug bounty: Immunefi program for vulnerability disclosure
- Timelock: Governance changes have time delays
- Multi-sig: Treasury and upgrades controlled by multi-signature wallets
Oracle Risk
2022 Avalanche Incident: Attackers manipulated AVAX prices on low-liquidity exchanges to exploit GMX's oracle pricing. LPs suffered significant losses. This highlighted the fundamental risk: GMX's model depends entirely on oracle accuracy.
Mitigations Since:
- Migration to Chainlink Data Streams (faster, more robust)
- Open interest caps per market
- Dynamic fees that increase with utilization
- Price impact fees for large positions
Counterparty Risk for LPs
LPs in GM pools are taking the opposite side of trader positions:
- If traders are net short and price rises, LPs profit
- If traders are net long and price rises, LPs lose
- Sustained directional trader profits erode LP capital
Our Security Rating: 3.5/5 — The July 2025 exploit (even with fund recovery) and oracle dependency concerns reduce confidence. V2 remains uncompromised, but the incident shows audits aren't guarantees.
GMX Review - Comparing GMX vs Hyperliquid vs dYdX
GMX vs Hyperliquid
| Factor | GMX | Hyperliquid |
| Model | Pool-based (oracle) | Orderbook |
| Slippage | Zero (oracle price) | Variable (orderbook) |
| Fees | 5-7 bps | 3.5 bps |
| Chains | 7 | 1 (own L1) |
| Liquidity Source | LP pools | Order flow |
| Security History | July 2025 exploit (recovered) | No major exploits |
Verdict: Hyperliquid wins on fees, security track record, and BTC/ETH liquidity depth. GMX wins on guaranteed execution and multi-chain availability. For large orders where slippage matters, GMX's zero-slippage model is valuable. For everyday trading, Hyperliquid is typically better.
GMX vs dYdX
Both offer perpetuals, but different models:
- GMX: Pool-based, oracle pricing, multi-chain
- dYdX: Orderbook, validator-run matching, own L1
For decentralization purists, dYdX's validator-run orderbook is more trustless. For execution guarantees, GMX's oracle pricing is more predictable.
Best Alternatives
- For lowest fees: Hyperliquid
- For true decentralization: dYdX
- For spot + perps: PancakeSwap
- For Solana-native: Jupiter perps
GMX Review - Yield Opportunities
GMX offers multiple yield products:
GMX Staking (22.23% APR)
Stake GMX tokens to earn:
- 30% of all protocol fees (paid in ETH/AVAX)
- Multiplier points (boost future rewards)
- Governance voting rights
This is real yield from trading activity, not inflationary emissions.
GLV Vaults (10.33% APR)
Auto-managed vaults that:
- Distribute across multiple GM pools
- Rebalance based on utilization
- Simplify LP experience
- Reduce single-market risk
GM Pools (Variable APR)
Direct liquidity provision to specific markets:
- Higher potential returns than GLV
- Concentrated exposure to one market
- Requires understanding of LP risks
APR Sustainability: Yields depend on trading volume and trader losses. In volatile markets with losing traders, APRs can exceed 30%. In calm markets or when traders profit, APRs decline and LPs may lose capital.
Conclusion GMX Review 2026
GMX offers a unique value proposition: guaranteed execution at oracle prices with zero slippage. This matters for large traders and anyone tired of orderbook manipulation.
The July 2025 security incident is a concern, though funds were recovered and V2 was unaffected. The team's response was swift, and the protocol continues operating normally.
GMX is best for:
- Large traders who need predictable execution
- Yield farmers seeking 10-22% real APR
- Multi-chain users wanting perps on Solana/BNB/Base
- Traders who value execution guarantees over lowest fees
GMX is NOT for:
- Fee-sensitive traders (use Hyperliquid)
- Those uncomfortable with oracle dependency
- LPs who don't understand counterparty risk
- Users concerned about the July 2025 incident
Our Rating: 3.8/5
Bottom Line: GMX carved out a valuable niche with its pool-based model. The July 2025 exploit is a blemish on the record, but fund recovery and V2 safety preserved user trust. Use it for guaranteed execution and yield opportunities; use Hyperliquid for better pricing on major pairs. The multi-chain expansion (especially Solana and Ethereum mainnet in late 2025) keeps GMX relevant.

Frequently Asked Questions
Is GMX safe after the July 2025 hack?
GMX V1 was exploited for $42M in July 2025, but the attacker returned the funds after accepting a $5M white-hat bounty. V2 contracts (GM pools, GLV vaults) were unaffected and continue operating normally. The incident revealed V1 vulnerabilities, but most users have migrated to V2. Still, it's a reminder that even audited protocols carry risk.
What are GMX fees?
Taker fees are 5-7 basis points (0.05-0.07%), with maker fees of 2-5 bps. VIP tiers based on 30-day volume reduce fees progressively. There's also a position fee (~0.1%) and variable borrow fees based on pool utilization. GMX stakers earn 30% of all protocol fees.
How much can I earn providing liquidity on GMX?
Current APRs: GMX staking yields 22.23%, GLV vaults yield 10.33%, and GM pools vary by market. These are real yields from trading fees, not token emissions. However, LPs face counterparty risk — sustained trader profits can erode LP capital. APRs fluctuate based on trading activity.
Is GMX better than Hyperliquid?
Different strengths. GMX offers zero slippage (trade at oracle price regardless of size) and multi-chain availability (7 chains vs 1). Hyperliquid has lower fees (3.5 bps vs 5-7 bps), deeper orderbook liquidity, and no major security incidents. Choose GMX for large orders and yield farming; choose Hyperliquid for everyday trading.
What chains does GMX support?
GMX operates on 7 chains: Arbitrum (largest), Avalanche, Base, BNB Chain, Ethereum (December 2025 launch), Solana (March 2025), and Botanix (Bitcoin L2). Each chain has independent liquidity pools, so depth varies. Arbitrum remains the primary chain with deepest liquidity.
What happened in the GMX July 2025 exploit?
On July 9, 2025, attackers exploited a reentrancy vulnerability in GMX V1's GLP pool contracts, draining $42M in assets. GMX immediately halted V1 trading and offered a white-hat bounty. The attacker accepted $5M and returned the remaining funds. V2 contracts were unaffected. The incident highlighted that even audited contracts can have vulnerabilities.
