Side-by-side comparison of two perpetual futures exchanges — updated in real time.
GMX v2 and SynFutures are both non-orderbook perp DEXes, but GMX v2 uses oracle-priced isolated pools on Arbitrum while SynFutures runs a concentrated liquidity AMM on Base.
GMX v2 operates with isolated GM pools on Arbitrum, listing 113 markets with 100x leverage and fees of 0.04% maker / 0.06% taker. SynFutures uses its Oyster AMM on Base with 280 markets, 100x leverage, zero maker fees, and a 0.05% taker fee. Both match on max leverage. SynFutures offers nearly 2.5x more markets and better fee rates for both makers (0% vs 0.04%) and takers (0.05% vs 0.06%). GMX v2 compensates with multi-collateral support (USDC, USDT, ETH, BTC) — a feature SynFutures lacks with its USDC-only model. GMX v2's isolated pool risk management means each market has independent parameters, while SynFutures' concentrated liquidity model requires LPs to actively manage positions. GMX v2's Arbitrum base provides access to a more established DeFi ecosystem than Base, though Base is growing rapidly. SynFutures' permissionless market creation drives faster pair expansion, while GMX v2 curates its listings. GMX v2 has a longer battle-tested history.
Choose GMX v2 for multi-asset collateral, isolated risk pools, and Arbitrum's established DeFi ecosystem. Choose SynFutures for lower fees (especially zero maker fee), more markets (280 vs 113), and permissionless market creation on Base.
