dYdX vs GMX

The short version
dYdX and GMX both helped define DeFi perps, then took opposite architectural paths. dYdX runs a mature on-chain central limit order book — now on its own Cosmos app-chain — with a wide market list and order-book fees. GMX built the liquidity-pool model, letting anyone provide perp liquidity for yield while traders trade against the pool at an oracle price.
For active order-book trading with more markets and lower per-trade costs, dYdX has the edge. For passive liquidity provision and a simple pool experience, GMX remains a trusted option.
Which should you use?
Choose dYdX if you want order-book execution, a broad market list and a long track record. Choose GMX if you'd rather provide liquidity passively or trade occasional swings against a pool on Arbitrum or Avalanche. Both are non-custodial and battle-tested.
Verdict
dYdX wins for active order-book traders and market breadth; GMX wins for passive LPs and simplicity. Your pick depends on whether you're trading or providing liquidity.
