There is no single “decentralized futures exchange” model, and no venue is cheapest or safest for every trade. GMX documents oracle-priced orders routed against liquidity pools; dYdX’s legacy v3 documentation describes a centralized order book with non-custodial settlement. Fees, margin, liquidation rules, and technical dependencies also differ. Compare the specific market, order type, collateral, trade size, and expected holding period—not just a headline fee or maximum leverage.
What should you compare before choosing a venue?
Perpetual futures let traders take leveraged long or short positions without a fixed expiry. Their costs and risks come from more than the opening trade: funding can accrue while a position is open, execution may involve price impact or network fees, and falling below a maintenance-margin requirement can trigger liquidation.
“Decentralized” does not tell you where orders are matched, how prices are determined, who holds collateral, or what infrastructure the trade depends on. Check the applicable product and version documentation, then verify live market parameters in the interface before placing an order. Protocol defaults and governance-controlled settings can change.

How do execution and custody differ?
GMX: pool-based, oracle-priced execution
GMX says it supports more than 100 markets across Arbitrum, Avalanche, and MegaETH, with trades routed against GM and GLV liquidity pools and prices quoted from oracle indexes. Its documentation says orders do not behave like passive limit orders resting on a centralized exchange’s book. An order’s execution can therefore depend on pool liquidity, oracle pricing, price-impact settings, and network execution—not just the displayed index price. GMX says its risk team can update per-market price-impact caps.

This is an LP revenue share, not a discount or rebate to traders.
dYdX: distinguish Chain from legacy v3
The dYdX Chain help articles describe default Chain rules for funding and liquidation. Separately, the older v3 technical documentation describes a centralized order book alongside non-custodial settlement, with trades and liquidations settled trustlessly. These are not interchangeable descriptions: identify whether a claim concerns dYdX Chain or v3 before relying on it for a trade.
Hyperliquid: verify the contract and collateral details
Hyperliquid’s cited contract specification describes USDC margining for USDT-denominated linear contracts. It says profit and loss are denominated in USDC without conversion using the USDC/USDT exchange rate. That means stablecoin exposure and any difference between USDC and USDT can matter to the position’s economics. Confirm the specific asset’s current contract specification rather than assuming every market uses identical terms.

What does a trade actually cost?
A headline commission is only one line in the cost of a leveraged position. To compare two venues fairly, hold constant the market, order size, maker or taker execution, account volume tier, collateral, chain, and holding period. Then account for the following:
- Trading commission: Check the fee schedule and whether the order is charged as maker or taker. dYdX’s April 23, 2026 help article says default taker fees depend on trailing 30-day USD volume across perpetual order books; it does not give one universal fee tier in the cited text, and governance can adjust settings.
- Spread and price impact: The execution price may differ from the quoted index or expected price. GMX documents price impact and says per-market caps can be updated.
- Funding: This is an ongoing transfer between long and short positions, not a one-time trading commission. Depending on the market and rate, it can add to or reduce a position’s PnL.
- Borrowing charges: GMX lists borrowing charges among possible costs where applicable. Check the position’s market-specific details.
- Network execution: A transaction can incur network costs in addition to the venue’s trading charges. The amount can depend on chain conditions and the transaction.
For dYdX’s documented default funding model, the interest component is zero, rates are based on sampled premiums, and funding settles hourly. The help article’s example of a 12% cap over eight hours for a large-cap market is a formula example under default parameters, not a typical observed rate, a forecast, or a live quote. Actual rates and governance settings can vary. Read “What are funding rates?” as a question about a recurring market mechanism, not a fixed percentage.
How much leverage is available—and what does it mean?
Published maxima are market-specific ceilings, not like-for-like safety ratings. GMX states up to 100x for supported markets; Hyperliquid documentation gives a range of 3x to 40x by asset. dYdX’s cited materials describe market-specific margin parameters rather than one universal current maximum. The applicable limit can be lower for a particular asset or change over time.

Leverage increases exposure relative to collateral. As a result, a smaller adverse price move can consume the margin supporting a highly leveraged position. A trader should compare initial and maintenance margin, collateral denomination, and whether a market’s rules apply across the account or to an individual position; do not infer those details from the maximum-leverage figure alone.
Hyperliquid’s documentation says maintenance margin is half the initial margin at maximum leverage. For USDT-denominated linear contracts, it also specifies USDC margin and USDC-denominated PnL. These are contract-specific mechanics, so check the current specification for the exact asset.
How does liquidation work on each venue?
Liquidation rules determine when a position no longer meets its required margin and how it is closed or penalized. “How to avoid liquidation?” has no universal answer across venues: monitor the maintenance requirement and position margin shown for that market, and understand which price reference and fees govern liquidation.
GMX
GMX documents market-specific liquidation configuration. Its liquidation documentation lists fees of 0.20% of position size for standard markets, 0.30% for single-token and synthetic markets, and 0.45% for high-volatility newly listed markets. These are GMX fee categories in the documentation accessed October 7, 2026, not comparable rates across venues; parameters can change. GMX says the fee is deducted when a position is closed and is not part of the liquidatability check. It also notes that borrow and funding fees can move liquidation prices closer.
dYdX Chain
The dYdX Chain help article says accounts below maintenance margin can be liquidated and that default settings use oracle prices for valuation. It describes a maximum liquidation penalty of 1.5% in default v4 software, with governance able to adjust the amount. Treat this as a documented default, not a guaranteed current setting for every market.
Hyperliquid
The cited Hyperliquid asset documentation establishes the maintenance-margin relationship at maximum leverage, but does not state a comparable liquidation fee or full liquidation execution process. Consult the current market and liquidation documentation before comparing it with GMX or dYdX.

A venue’s risk profile includes the systems that support its trades, not just the contract’s price movement. The relevant dependencies in these materials include:
- Smart contracts: Contract defects or exploits can create losses. GMX states: “GMX mitigates risks through testing, audits, and bug bounties, but trading on any smart contract protocol carries inherent risks.” These safeguards do not eliminate risk.
- Oracle inputs: Oracle-priced execution and liquidation depend on price feeds and the rules for using them. GMX describes oracle-index pricing; dYdX Chain’s default liquidation rules use oracle valuation.
- Liquidity and execution: GMX trades against liquidity pools, so pool conditions and price impact matter. The order-book description in the cited dYdX v3 documentation is specific to that older version.
- Governance and configuration: dYdX says governance may adjust fee and liquidation settings; GMX documents market-specific settings that can be updated. A previously read parameter may no longer match the live market.
- Collateral and network conditions: Stablecoin denomination can affect exposure, while blockchain execution can add costs or affect transaction timing. Confirm the collateral terms and network used for the market you intend to trade.
How to make a venue comparison for your own trade
- Choose the exact market and version. Identify the asset, contract, chain, and—where applicable—whether dYdX information refers to Chain or legacy v3.
- Set the trade assumptions. Specify order size, maker or taker behavior, collateral, leverage, and expected time in the position.
- Estimate all costs. Include the applicable commission, price impact or spread, funding over the intended holding period, borrowing charges where applicable, and network execution costs.
- Check margin and liquidation parameters. Review initial and maintenance margin, liquidation price calculation, relevant fees or penalties, and the price reference used by the venue.
- Review dependencies and current settings. Check the current market interface and official documentation for oracle, liquidity, collateral, and governance-controlled parameters.
This process can identify a venue that fits a particular trade, but the figures in different fee or liquidation systems should not be ranked as though they measured the same thing. A lower stated commission, higher leverage ceiling, or different liquidation charge alone does not establish lower total cost or lower risk.
