Perp DEX comparison: Hyperliquid, Aster, Lighter and others

01Same promise, very different machines underneath

Open the front page of any of these and you read the same three lines: no account, low fees, your keys. What the front page does not say is how your order gets its price, and that is the part that decides what the trade costs you. Hyperliquid, Lighter, Pacifica, edgeX, Extended and Aster all run an order book: your order meets orders other traders have already placed, so your price is whatever is sitting in that book at the second you press the button. On a busy market like BTC that is comfortable; on a small market a market order can eat through several levels and fill noticeably worse than the number you saw on screen.

Variational's Omni works the other way round. There is no order book at all: you ask for a price, and one market maker answers with a firm quote that can come out better or worse than the indicative number on screen. That market maker is the other side of every trade there, and because there is no trading fee, the cost sits in the gap between its buy and sell price. How Omni works step by step — sign-up, the access code, fees and points — is in our Variational review. Ostium has no order book either. You get a quoted buy and sell price built from its own price feed, and a pool of other people's money (the vault) sits on the other side of your trade; you pay an opening fee of 0.03–0.10% of your position, a flat $0.10 per price request, and a daily rollover charge instead of funding.

Aster sits in its own place, because most beginners meet it without ever visiting a DEX website. It is the execution partner behind the Perpetuals tab inside Binance Wallet, so the wallet is what you actually use and the order book is shared with Aster. If that route interests you, our pages on perpetuals in Binance Wallet and on Aster directly versus inside the wallet cover both ways in.

02The eight side by side

Numbers checked 22 October 2026. Where a venue does not publish a figure, the cell says to check in the app — these terms change often, so look at the live screen before you trade. The first column after the name is the one beginners trip over: you have to send your money on that exact chain, and USDC on Solana is not the same thing as USDC on Arbitrum.

Two words come up in every fee cell below. You pay the taker fee when your order fills straight away at the price on screen, and the maker fee when you place a limit order that sits and waits for someone else to trade with it. Most first trades are taker trades, so that is the number to read first.

One line in that table deserves a translation. The 300 ms delay on Lighter's Standard account means your taker order is held for a third of a second before it reaches the book — on a quiet market you will not notice, on a fast one your fill can land a little away from the price you saw. That is the price of the zero, and the Premium account is where you pay a fee to get rid of most of it.

Two habits save you from a surprise on the first invoice. On Aster, open the fee page and find which group your pair is in before you trade it, because the difference between 0.04% and 0.1% on a small coin is more than double. And on Hyperliquid, the order form shows your fee before you confirm, with the fee page in the app as the number to trust — check it there rather than taking a figure from a review site.

Every one of these venues blocks some countries, and every list ends with "including but not limited to". The US appears on every published list; Hyperliquid names no countries at all — its app simply loads with a restriction notice. Several of the others also block the UK, Russia, Ukraine or China. Open the venue's terms page, search for your own country, and if the app shows a restriction notice, stop there — there is no safe way around a block, and trying one puts your money at risk rather than solving anything.

03What one small trade really costs

Take the same trade everywhere: 100 USDC of your money at 5x, which is a 500 USDC position. Fees are charged on the 500, once when you open and once when you close. Entering and exiting with market orders on Aster's main crypto pairs costs 0.20 USDC each way, so 0.40 for the round trip. Pacifica works out the same at 0.40. Extended comes to 0.25, edgeX to about 0.45 on its base rate, and Lighter's Standard account to nothing at all — in exchange for that 300 ms hold on your taker orders. On Ostium there is no closing fee, but the opening fee on 500 USDC is 0.15–0.50 depending on the asset, plus the $0.10 price-feed charge, which is refunded if you close the position in full. Hyperliquid is missing from this list on purpose: its rate depends on your trading volume, so the only honest number is the one in the order form before you confirm. Look there first, then compare it with the figures above.

Omni is the one where the cost hides in a different place. It shows a line called Spread in the order form — that is half the gap between the buy and sell price for your size. That gap is the cost; there is no separate trading fee, so read that number before you confirm, and 0.1 USDC leaves your balance each time money moves in or out.

Then there is the cost of holding. Funding is a payment between traders, not a fee the venue keeps, and an hourly interval does not mean eight times the cost: Hyperliquid works out an eight-hour rate and pays one eighth of it every hour, and Lighter divides its premium by eight the same way. The same money simply arrives in smaller slices, and you only pay for the hours you actually hold. Ostium is the odd one out with a daily rollover instead. On top of all of it sits the network fee to get your money onto the right chain and back out again, which on a 100 USDC test can easily be the largest single line.

04What can go wrong when there is no support desk

Your money sits in smart contracts, so a bug in those contracts or in the bridge that brought your USDC there is a real line of risk, not a theoretical one. Price feeds are the other soft spot: on 15 July 2026 Ostium's liquidity vault lost 23.75 million USDC to forged prices. Traders' own collateral was not taken and trading resumed on 23 July, but it is a clear example of what a price-feed problem can do. It helps to understand why the price that closes your position is not the last trade on screen — that is covered in index, mark and last price.

The quieter risks are the everyday ones. Nobody can reverse a wrong click or recover a deposit sent on the wrong network — Pacifica, for example, credits USDC on Solana only. If you lose access to the wallet, you lose access to the money, and there is no password reset. And on smaller markets the book can be thin even on a venue with a busy BTC market, so check the depth on the specific contract you want, not the venue's overall numbers.

05Which route fits which beginner

If you have never placed a futures order at all, none of this is where to learn the buttons — a demo account on a centralised exchange costs nothing and risks nothing, and you can come back here afterwards. If you already know how to open and close a position and want to see an on-chain order book with your own eyes, Hyperliquid is the most open door: no registration, you connect a wallet on Hyperliquid, deposit USDC, and the book is on screen — our Hyperliquid guide walks through the setup. If you already use Binance and do not want to touch a separate site, the Perpetuals tab in Binance Wallet gets you to the same kind of product through an app you know.

If one specific venue above caught your eye, each has its own page here: Lighter, Pacifica, Extended, edgeX and Ostium. Read the one you are drawn to in full before you send money, because the access rules and the deposit network are where beginners lose time and small amounts.

1. Check access and the network before anything else

   Open the venue, connect your wallet and see whether it loads or shows a restriction notice. Then note which chain and which token it accepts — USDC on Solana, USDC on Arbitrum and USDT on BNB Chain are not interchangeable.

2. Send a test amount you would not mind losing

   Something like 20–50 USDC. The point of the first transfer is to confirm the network, the address and the arrival time, not to make money.

3. Open one small position on a liquid market

   Isolated margin, low leverage, a market everyone trades. Watch the fill price against what the screen showed you before the click.

4. Set the stop, then write down the result

   Entry fee, exit fee, funding paid, network fees both ways. That number, not the marketing page, tells you what this venue costs you.
