At a glance
Two of the largest decentralized perpetuals platforms take different paths: GMX ↗ uses a shared liquidity pool where LPs act as the counterparty, while dYdX ↗ operates a traditional off-chain order book on its own Cosmos appchain. GMX targets users who want passive yield and straightforward perp trading across Arbitrum, Avalanche, and Solana. dYdX caters to pro traders with advanced order types and high throughput on a dedicated chain. This comparison breaks down the key tradeoffs.
Key differences
Mechanism – GMX relies on GLP (v1) and GM (v2) liquidity pools: LPs deposit assets and effectively bet against traders. dYdX uses a centralized limit order book (CLOB) off-chain, with on-chain settlement via validators on dYdX Chain. The pool model simplifies user experience but can lead to divergent loss for LPs; the order book feels familiar to CEX traders and supports more precise execution.
Chains – GMX is live on Arbitrum, Avalanche, and Solana ($0.17B TVL). dYdX exists exclusively on its Cosmos-based appchain ($0.13B TVL). Multi-chain presence gives GMX broader composability, while dYdX’s sovereign chain allows greater control over infrastructure and fee capture.
TVL and age – As of 2026-05-28, GMX holds $0.17B TVL vs dYdX’s $0.13B. dYdX launched in 2017, making it a veteran; GMX launched in 2021 but has accumulated more locked value.
Governance – Both are DAO-governed (GMX DAO, dYdX DAO) with native tokens (GMX, DYDX) used for staking and fee distribution.
Security and track record
GMX has been audited by ABDK, Quantstamp, and Guardian Audits. dYdX was audited by Informal Systems and Bware Labs. Our incident data shows one incident for GMX — a July 2025 reentrancy exploit that drained about $42M from a GMX V1 (GLP) pool on Arbitrum, after which the attacker returned nearly all the funds and GMX V2 was unaffected — and none for dYdX. dYdX’s longer history (since 2017) and migration from StarkEx to its own chain in 2023 demonstrate battle-testing through major architectural changes. GMX introduced isolated GM markets with v2, which added risk isolation but hasn’t led to reported security events. Security is broadly comparable; the main risk vectors differ: smart contract risk across multiple chains for GMX vs validator-dependent liveness and bridge risk on dYdX Chain.
Fees and costs
Specific fee schedules are not provided in our dataset. GMX typically charges a flat open/close fee (~0.1%) that accrues to LPs and GMX stakers. dYdX employs a maker/taker fee model, with low takers fees (often <0.05%) and maker rebates. Actual costs depend on asset, volume, and staking tier. Check each protocol’s documentation for current rates.
Which should you choose
Pick GMX if you value multi-chain access, want to provide liquidity passively through pools, or prefer a simple perp trading interface with a single pool counterparty.
Pick dYdX if you are an active trader who needs an advanced order book with limit orders, need high throughput, or want to trade on a sovereign chain with fee capture aligned to the DYDX token.
Verdict
There is no blanket winner. The choice hinges on trading style and ecosystem preference. For passive LPs and multi-chain simplicity, GMX is stronger. For pro traders who demand order-book precision and don’t mind a single-chain environment, dYdX remains a top contender.
