What is GMX? Perpetual DEX on Arbitrum and Avalanche Explained

GMX launched in 2021 on Arbitrum and Avalanche, pioneering the 'liquidity pool perp DEX' model: instead of an order book, traders bet against a shared pool (GLP) of assets. When traders lose, GLP holders profit; when traders win, GLP absorbs the loss. This model removes the need for external market makers but concentrates risk in the pool.

GMX V2 (2023) introduced isolated markets with separate liquidity pools per asset pair, improving capital efficiency and reducing cross-asset contagion risk. GMX remains among the top perpetual DEXes by TVL on Arbitrum, though Hyperliquid has overtaken it in trading volume with its custom L1 order-book architecture.

How GMX trading works

• Open long or short perpetual positions on BTC, ETH, and other assets with up to 50× leverage
• Positions are opened against GLP — the protocol's multi-asset liquidity pool
• Funding rates balance long/short demand; paid between traders periodically
• Low swap fees (0.05–0.07%) and zero price impact on standard position sizes via oracle pricing
• Chainlink oracle prices determine entry, exit, and liquidation levels

GLP — the liquidity provider token

• GLP is an index of BTC, ETH, USDC, UNI, LINK, and other assets — minted by depositing any constituent
• GLP holders earn 70% of GMX trading fees (paid in ETH/AVAX) plus esGMX rewards
• Risk: GLP loses value when traders net profit; gains when traders net lose
• GMX V2: isolated GLP pools per market reduce cross-asset risk versus V1's single pool

GMX vs Hyperliquid and dYdX

• vs Hyperliquid: GMX uses pool-based pricing on Arbitrum; Hyperliquid uses an on-chain order book on its own L1 with higher volume in 2026
• vs dYdX: Both offer perps; dYdX V4 uses an order book on Cosmos; GMX stays on Arbitrum/Avalanche with pool model
• GMX advantage: Longer track record on Ethereum L2s, deep Arbitrum DeFi composability, simpler LP participation via GLP
• GMX disadvantage: Pool model creates adversarial dynamic between traders and GLP; oracle dependency for pricing
