Best Perp DEX in 2026: Hyperliquid, Aster, dYdX, GMX, and Lighter

A perpetual DEX is a decentralized exchange for perpetual futures — leveraged derivatives with no expiry date, settled peer-to-peer or against a liquidity pool instead of by a centralized order-book operator. New to leverage, margin, and funding? Read perpetuals explained first.

This roundup compares the five decentralized perp exchanges we cover — Hyperliquid, Aster, dYdX, GMX, and Lighter — on architecture, posted fees, KYC, and what each is genuinely good for. See our methodology for how we source and verify these figures, and perp DEX safety for the custody, contract, and incident-history risks that sit behind any ranking.

Rates as re-read from each venue's official docs on its fee page (Hyperliquid and Lighter re-checked 6 October 2026, GMX 18 September, dYdX 21 September, Aster 29 September); terms, restrictions and the Kalshi section re-read 6–7 October 2026.

Since this roundup was written, the comparison has also gone live-data: the fee comparison holds every venue's verified schedule in one table, the earning comparison covers what each venue offers beyond trading (with live funding and vault yields), the earning scenarios tool ranks the venues for your specific volume and maker/taker mix, and the feature comparison lays out order types, collateral, and wallet support side by side.

Verdict

TL;DR. There's no single “best” perp DEX — it depends on how you trade. Hyperliquid leads on product breadth; Aster and Lighter compete hardest on fees (0% maker); dYdX has run perps since 2020 and pays maker rebates at scale, though it retired most of its markets in 2026; GMX is the pool-model outlier that lets you earn fee share instead of trading. Pick by your priority, not a ranking.

Comparison table

Perp DEX comparison across covered venues
Venue Architecture Base perp fees KYC Notable trait
Hyperliquid Own L1, on-chain order book 0.045% taker / 0.015% maker (tiers to 0.024% taker) None Perps, spot and vaults in one account on its own L1
Aster Order book on its own L1 (Aster Chain) 0% maker; 0.04% taker on crypto pairs, 0.1% on Group B, 0.0125% on RWA None 5% fee discount when paying in ASTER
dYdX Own Cosmos-SDK chain Tier 1: 0.01% maker / 0.05% taker (rebates to −0.011% maker at top tiers) None Perps since April 2020; maker rebates at top tiers; most markets retired in 2026
GMX Pool model, Arbitrum, Avalanche & MegaETH Position fee 0.04%–0.06% (by OI-balance effect) + borrow fee while held None LPs earn 63% of fees on Arbitrum and Avalanche
Lighter zk-rollup on Ethereum 0% maker / 0% taker (Standard Accounts) Not stated in docs LIT token live (staking 6% APR); points programme status contested in its own docs

Worth being direct: Hyperliquid is our top pick below, but not because it's cheapest. On posted fees, Aster and Lighter both undercut it — Aster charges 0% maker on both markets, Lighter 0% on both sides outright. dYdX also beats Hyperliquid's base maker fee (0.01% vs. 0.015%) before rebates. Hyperliquid's case rests on liquidity depth, product breadth, and track record — not rate-card price.

Hyperliquid

Hyperliquid runs its own layer-1 blockchain built to host a fully on-chain order book, with every order, cancellation, and fill processed on-chain. Base perp fees are 0.045% taker / 0.015% maker, improving with volume to as low as 0.024% taker; HYPE staking adds a further 5–40% discount, and a referral link cuts 4% off fees on the first $25M traded. Funding is hourly and peer-to-peer between longs and shorts. No KYC is required — connect a wallet and deposit — though US persons are blocked, and its legacy Arbitrum bridge carries a published Zellic audit. Its live 24-hour volume and open interest sit beside Aster's, Lighter's and dYdX's on our volume tool, read from each venue's own API.

Best for: active order-book traders who want the widest product range, and are comfortable self-custodying on a dedicated chain. Full review: Hyperliquid.

Aster

Aster is an order-book perp DEX on its own L1, Aster Chain, with privacy on by default. Fees split by pair category: crypto pairs run 0% maker / 0.04% taker in USDT or USD1, RWA pairs 0% maker / 0.0125% taker, and a Group B list 0.1% taker. Paying fees in ASTER, the platform's native token, knocks a further 5% off. No identity verification is required to trade. Because both markets post a 0% maker fee with no volume tier to unlock it, Aster is one of the more straightforward venues to trade cheaply from day one.

Best for: maker-order traders who want a 0% maker fee from the first trade, with no volume threshold. Full review: Aster; head-to-head: Hyperliquid vs Aster.

dYdX

dYdX runs on its own Cosmos-SDK application chain, a different sovereign-chain approach from Hyperliquid's purpose-built L1. Its governance-set fee schedule opens at tier 1 with 0.01% maker / 0.05% taker, improving into a rebate — down to −0.011% maker — at the top volume tiers, so high-volume makers get paid to post liquidity, and its docs now pay "50% trading rebates directly after each trade" in place of the token rewards they replaced. No KYC is required, and dYdX has run perpetual markets since April 2020, across multiple protocol versions. The market list is the catch: governance retired most of dYdX's markets in scheduled batches during 2026 — our incident tracker reads "Most of its markets wound down in 2026 — 73 active, 223 in final settlement" as of 2026-10-07 — so check that your market still trades before planning around it. The dYdX review carries the running notice.

Best for: limit-order traders planning to scale volume over time on the markets that remain, since the maker schedule rewards exactly that. Full review: dYdX; head-to-head: Hyperliquid vs dYdX.

GMX

GMX takes a different architecture entirely: instead of an order book, it runs a pool model on Arbitrum, Avalanche and MegaETH, where a GM liquidity pool is the counterparty to every trade. Trading costs a position fee of 0.04% to 0.06% of size depending on whether the trade balances or worsens the pool's open-interest skew, plus a borrow fee that accrues while a position stays open. There's no identity check to trade. For many users the draw isn't trading at all: liquidity providers who deposit into a GM pool earn 63% of the fees it generates on Arbitrum and Avalanche.

Best for: traders comfortable with pool-based pricing, and especially anyone more interested in earning a fee share as a liquidity provider than trading directionally. Full review: GMX; head-to-head: Hyperliquid vs GMX.

Lighter

Lighter is a zero-knowledge rollup on Ethereum, so its trade settlement inherits Ethereum's base-layer security rather than relying on a standalone validator set. Its defining feature is fees: Standard Accounts pay 0% on both maker and taker sides, on every market, and funding is peer-to-peer with no cut taken by the platform. For traders running frequent or large-size activity, that removes what is normally the largest recurring trading cost rather than merely discounting it. Lighter's docs don't describe an identity-verification step; onboarding is wallet-based. Its LIT utility token is live with staking (6% APR). Its points programme is harder to pin down: one docs page says Season 2 ended in December 2025 while two others still describe weekly drops — see our Lighter points page for what is and isn't documented.

Best for: cost-zero experimenters and high-frequency traders who want to test strategies or run size without fee drag. Full comparison: Hyperliquid vs Lighter.

Other venues worth comparing

The five above are the venues we cover in depth and have referral relationships with. Several others are large or fast-growing enough to belong in the conversation — we have no commercial relationship with them, but here is the honest one-line read and a full head-to-head for each:

The site also reviews Variational Omni, SoDEX, Nado, Vest, Derive, Ondo Perps and Veranta; the fee comparison puts every covered venue's schedule side by side.

A regulated, centralized alternative: Kalshi Perpetuals

Every venue above is a decentralized exchange — you trade from your own wallet. If you would rather trade perps on a CFTC-regulated, centralized platform, Kalshi Perpetuals is the one to know: on 29 May 2026 the CFTC approved Kalshi's bitcoin perpetual, "a perpetual contract that references the spot price of bitcoin, as a futures contract", after Commission review (CFTC release 9240-26). It was not the first US perp: Bitnomial self-certified a BTC perpetual in April 2025 under the CFTC's self-certification rule rather than seeking Commission approval, and calls it "the first U.S. perpetual futures" (Bitnomial). Kalshi lists its perps alongside its prediction markets. It is not a DEX — Kalshi custodies your funds and runs a centralized order book — so it is a fundamentally different trust model from the venues above: federal regulation in exchange for giving up self-custody.

Availability is US-only for perpetuals. Kalshi's help centre says "US-based Kalshi users who have completed KYC verification are eligible to apply. International availability may expand in the future", and access then takes a margin-account application with a questionnaire, handled through its FCM, Kalshi Prime (Kalshi help). Kalshi's event contracts reach more countries, but its Member Agreement bars 55 jurisdictions from those too, including the UK, France, Canada and Australia. The sign-up page our link opens says the referrer "sent you $25 on Kalshi" (checked 7 October 2026); the trading requirement to unlock it is shown in the app, the credit is for trading rather than withdrawal and expires seven days after issue, and "Referral incentives are only available to U.S. users at this time" (Kalshi referral FAQ).

Which should you pick?

The right venue depends more on how you trade than on any single "best" label:

FAQ

Is a perp DEX safer than a CEX?

Not simply "safer" or "riskier" — the risk shapes differ. A CEX holds your funds and can freeze, mismanage, or lose them through insolvency; a DEX removes that custody risk since you trade from your own wallet, but adds smart-contract, bridge, and unregulated-venue risk instead. See Is Hyperliquid safe? for how that trade-off plays out on one venue.

Which perp DEX is cheapest?

It depends on whether you're a maker or taker and how long you hold positions. Lighter's Standard Accounts post zero fees on both sides — the lowest posted rate here — and Aster or dYdX can also beat Hyperliquid depending on role and tier. Funding, which applies on every venue regardless of posted fees, matters more than the headline rate over time.

Do any of these require KYC?

No — none of the five puts an identity-verification step in its onboarding flow; access is a wallet signature (or email login where offered), though Aster's terms reserve the right to "implement limited identity verification procedures to comply with applicable regulations". Geo-restrictions are a separate question, enforced at the terms level: all five exclude the US. dYdX also restricts Canada and the UK; Lighter's list adds Canada, the UK and China; Aster's adds Canada, the UK, China, North Korea, Russia, Ukraine, Cuba, Iran, Venezuela and Syria; all of them exclude sanctioned jurisdictions. GMX's terms also explicitly prohibit VPN circumvention. Per-venue detail is on each hub's KYC or how-to-start page; policies change, so re-check the venue's terms before relying on this.
