# KuCoin Alternatives for Perpetual Futures, Scored End to End Updated: 24 September 2026; Terms read 18 September 2026; Books checked to 22 September 2026; The Switch Guide editors Lighter tops this ranking of kucoin alternatives with 25.3 of 30 on 24 September 2026, ahead of edgeX at 23.2 and Extended at 23.1. It wins on two of the six criteria and never finishes last on any. Leverage shortens the distance between a position and its own margin, and moving venue does not lengthen it. ## Where each venue lands Weights, fixed 22 September 2026 before a venue on this site was scored: Book depth we measured 28 · Who holds the collateral 22 · Cost of a round trip 18 · Markets on offer 14 · Record so far 12 · Whether the door opens 6. Method in full: https://doliacats.com/methodology Ordered by the overall switch score. | No. | Venue | Score of 30 | Maker / taker | Perp markets | BTC leverage | |---|---|---|---|---|---| | 1 | Lighter | 25.3 | 0% / 0% | 214 | 50x, 2% margin | | 2 | edgeX | 23.2 | 0.040% / 0.045% | 172 | 100x to $1 million | | 3 | Extended | 23.1 | 0% / 0.025% | 325 | 50x to $4 million | | 4 | Aster | 23.0 | 0% / 0.040% | 578 | 200x to 400 USDT | | 5 | EVEDEX | 19.6 | 0.015% / 0.045% | 52 | 200x to $50,000 | | 6 | Aevo | 16.4 | 0.050% / 0.080% | 102 | 20x, 5% margin | ## Before you move 1. Ahead on cost and custody: Lighter charges 0% maker / 0% taker and documents an exit that works without its operator. 2. Ahead on the book: edgeX held $29.1 million within 10 basis points, more than the $8.1 million we measured on KuCoin's own BTC perpetual. 3. Ahead on the record: Extended and Aster both publish a bug bounty and neither has lost user money in the last 24 months. 4. Ahead on breadth in one account: EVEDEX carries 52 contracts across six asset classes; Aster carries 578 in crypto and a handful beyond. ## What we measured ourselves BTC perpetual order books read every 10 minutes in the hours between 07:10 and 23:58 UTC on 22 September 2026; every figure is the median of the successful readings. | Venue | Round trip on $10,000 | Depth within 10 bps | Impact of a $100,000 order | Readings | |---|---|---|---|---| | Lighter | $0.00 | $17.4 million | 0.70 bps | 93 | | edgeX | $9.00 | $29.1 million | 0.02 bps | 94 | | Extended | $5.00 | $7.7 million | 0.06 bps | 93 | | Aster | $8.00 | $14.8 million | 0.56 bps | 94 | | EVEDEX | $9.00 | $18.9 million | 2.06 bps | 94 | | Aevo | $16.00 | $1.7 million | 4.03 bps | 94 | ## Step 1 — What separates these six All six take orders from a wallet, keep collateral in contracts or on their own chain, and ask for no identity documents. On those points the choice is already made and none of them is the reason to pick one over another. The separation happens on four questions. **How the chain records a trade** — every trade or its proof, as on Extended and Lighter, or periodic position snapshots, as on EVEDEX. **Whether there is a way out without the operator** — Lighter and edgeX describe one; the other four do not. **What it costs** — a $10,000 round trip runs from $0.00 to $16.00 across this page. **What the record shows** — Extended and Aster publish a bounty, Aevo's legacy vaults lost about $2.7 million in December 2025. Those four are what the weights are for. The order below is the arithmetic, not an opinion, and the score of any venue on this page is the same score it carries everywhere else on this site. ## Venue 1 — [Lighter](https://lighter.xyz), move here for the fewest weak columns of the six (25.3 of 30) 0% maker / 0% taker on a standard account, a median $17.4 million within 10 basis points, 214 markets, and an exit through Ethereum documented for the day the sequencer stops ([Lighter docs](https://docs.lighter.xyz/about-lighter/technical-architecture-lighter-core.md), checked 18 September 2026). Nine audit reports from 2025 and 2026 cover the circuits and the contracts. **Where it gives way:** the record. There is no bug bounty, and the free rate costs 300 ms of latency on every take. - Getting in: Wallet signature. - Worth moving: 0% maker / 0% taker with $17.4 million of resting BTC depth behind it; Proofs on Ethereum and a documented exit without the operator. - Worth knowing: No published bug bounty programme; 300 ms of added latency on takes at the free rate. - Not for: anything that depends on being early. ## Venue 2 — [edgeX](https://pro.edgex.exchange), move here for the deepest book on the page, at the second-dearest maker rate on it (23.2 of 30) The deepest reading among the venues scored here, $29.1 million within 10 basis points, on a venue that commits each change of state to rollup contracts and documents a withdrawal that bypasses the operator ([edgeX docs](https://pro.edgex.exchange/en-US/home), checked 18 September 2026). 172 contracts, 93 of them shares and exchange-traded funds. **Where it gives way:** cost. 0.040% at the entry tier is dearer than every maker rate on this page but Aevo's 0.050%, and only Aevo asks more of a taker. - Getting in: Wallet or MPC login. - Worth moving: $29.1 million of resting BTC depth, the deepest of the venues scored here; Withdrawal without the operator described step by step. - Worth knowing: 0.040% maker / 0.045% taker at the entry tier; No bug bounty programme published. - Not for: makers, who pay 0.040% on every resting order. ## Venue 3 — [Extended](https://extended.exchange/), move here for a full score on the record, at one rate for everybody (23.1 of 30) Every transaction validated and settled on Starknet ([Extended docs](https://docs.extended.exchange/about-extended/technical-architecture), checked 18 September 2026), two audits of the contracts it uses, a bug bounty of up to $500,000 and no loss of user money on record — the full ten points on that criterion. One rate for everybody, 0% maker / 0.025% taker. **Where it gives way:** the book. Of 325 markets, 278 are quoted on request, and the BTC book held $7.7 million. - Getting in: Wallet signature, EVM or Starknet. - Worth moving: A $500,000 bug bounty and no user-fund loss on record; 0% maker / 0.025% taker for every account, settled on Starknet trade by trade. - Worth knowing: Most of its market count has no public order book; No forced withdrawal in the documentation we read. - Not for: traders whose market is quoted on request. ## Venue 4 — [Aster](https://www.asterdex.com), move here for the longest market list, on a chain its operator runs (23.0 of 30) 578 perpetual contracts, 0% maker / 0.040% taker at the entry tier, a 0.01 bps median spread level with Lighter's, an Immunefi bounty of up to $200,000 and users reimbursed after its own 2025 mispricing. **Where it gives way:** custody. Matching and settlement run on Aster Chain ([Aster docs](https://docs.asterdex.com/overview/what-is-aster.md), checked 18 September 2026), whose core code is closed, which ran phase one without outside validators, and which documents no forced withdrawal. - Getting in: Wallet signature or email. - Worth moving: 578 contracts at 0% maker / 0.040% taker, with a $200,000 bounty; 0.01 bps median spread, level with Lighter at the tightest here. - Worth knowing: Operator-run chain with closed core code; No forced withdrawal documented and a validator-signed bridge. - Not for: anyone leaving a centralised venue because one company held the keys. ## Venue 5 — EVEDEX, move here for six asset classes on one balance (19.6 of 30) 52 perpetual contracts across crypto, five US stocks, an index, Tether Gold, silver, WTI crude oil, two currency pairs and two pre-IPO names, at 0.015% maker / 0.045% taker with a median $18.9 million of BTC depth behind them. Two CertiK audits of the smart contracts, the latest delivered 28 July 2025 with one informational finding, acknowledged, and nothing critical, major, medium or minor; CertiK Skynet rated the project 94.36, grade AAA, read on 23 September 2026 ([CertiK Skynet](https://skynet.certik.com/projects/evedex)). **Where it gives way:** the chain record. Positions are written to Arbitrum in batches rather than trade by trade. - Getting in: Wallet signature. - Worth moving: Six asset classes on one balance, all on a 24/7 schedule; $18.9 million of measured BTC depth, second only to edgeX in this guide. - Worth knowing: Positions reach Arbitrum in periodic batches, and no forced withdrawal is documented; No bug bounty listed on CertiK Skynet, checked 18 September 2026; 52 markets against hundreds elsewhere, no spot market, and cross margin only. - Not for: traders who want per-trade settlement or a long altcoin list. ## Venue 6 — [Aevo](https://www.aevo.xyz/), move here for equity and pre-IPO perps for a trader who is not price-sensitive (16.4 of 30) Aevo matches off-chain and settles on its own OP Stack rollup, with batches posted to Ethereum ([Aevo docs](https://www.aevo.xyz/docs/readme), checked 18 September 2026). 102 markets cover equities, commodities, exchange-traded funds, currencies and pre-IPO names. **Where it gives way:** everything to do with price and record. 0.050% maker / 0.080% taker is the most expensive pair here, BTC is capped at 20x, and the team's legacy Ribbon vaults were exploited for about $2.7 million in December 2025. - Getting in: Wallet connect. - Worth moving: Five asset classes beyond crypto on one rollup; Every trade settled in rollup contracts, with five published audits. - Worth knowing: 0.050% maker / 0.080% taker, a $16.00 round trip on $10,000; Legacy Ribbon vaults exploited for about $2.7 million in December 2025, with a 19% haircut for vault users. - Not for: anyone trading often enough to notice the fee. ## In their own words > "Aevo is a decentralized derivatives exchange built on a custom OP Stack Layer 2." — Aevo documentation, Read me, 18 September 2026. https://www.aevo.xyz/docs/readme > "By default, edgeX operates with a cross-margin system, allowing collateral to be shared among all positions within a single trading account." — edgeX documentation, Trading accounts and margin, 18 September 2026. https://edgex-1.gitbook.io/edgeX-documentation/trading/trading-accounts-and-margin > "2 Audits available | Last Audit was delivered on Jul 28, 2025" — CertiK Skynet, EVEDEX project profile, 18 September 2026. https://skynet.certik.com/projects/evedex ## FAQ from people mid-switch ### What is a good alternative to KuCoin? On the full score, Lighter at 25.3 of 30, then edgeX at 23.2. On depth, edgeX held $29.1 million within 10 basis points against $8.1 million on KuCoin's own BTC perpetual the same day, which is a wider gap than most people expect. ### Is KuCoin better than a DEX? For spot altcoins and fiat rails, yes. For BTC perpetual depth, our readings say otherwise: KuCoin held $8.1 million within 10 basis points while edgeX held $29.1 million and Lighter $17.4 million, with no account and no documents needed at any of them. ### How are crypto exchanges rated? Here, on six weighted criteria fixed before anything was scored: book depth we measured 28, who holds the collateral 22, cost of a round trip 18, markets on offer 14, record so far 12 and whether the door opens 6. The arithmetic is on [how we rate](/methodology). ### What should I look for in a crypto exchange? Where the collateral sits, whether a withdrawal works when the operator does not, what a round trip costs, and whether the markets you trade have a public book. Two of the six venues here document an exit without the operator, and one quotes 278 of its markets on request. ### Are perp DEXs worth it for small accounts? Cost says yes: a $10,000 round trip is $0.00 on Lighter and $5.00 on Extended, with no minimum tier to reach. The catch is that there is no support desk and no recovery, which matters more when the account is the only one you have. ### Which crypto exchange has the best security record? Of these six, Extended and Aster score the full ten on our record criterion: published audits, a live bug bounty and no loss of user money in 24 months. Aevo scores lowest, after its legacy vaults were exploited for about $2.7 million in December 2025. ### Do I need an account to trade on these venues? No. All six open from a wallet signature and none asks for identity documents to trade. Several still reserve the right to look at what arrives: Extended's terms allow it to refuse access after a transaction risk assessment, and EVEDEX screens deposits on-chain instead of checking the person. ### What is the difference between a hybrid exchange and a DEX? A hybrid matches orders on a server the operator runs and records the result on a chain. A venue that keeps the book inside its own consensus does the matching in public and slower. Custody sits in contracts either way, which is why the label settles less than it appears to. ### Can I lose money on a DEX outage? You can lose the ability to close a position, which in a fast market amounts to the same thing. That is why a documented exit that works without the operator earns points here: edgeX and Lighter describe one, and where none exists an outage turns into a wait of unknown length. ### How often are these scores updated? Whenever something behind them moves. A venue that changes a fee schedule, rewrites a leverage ladder or edits its terms is read again and scored again, and the page then carries a new date and a line saying what moved. No date here is pushed forward to look fresh. The schedule is on [how we rate](/methodology). ## Where every figure on this page came from One of the six numbers is ours and five are quotations. Depth is measured here, in the window this page names. Fees, markets, ladders, sign-in, who the terms refuse and audit history were lifted from each venue's own documentation and terms on 18 September 2026. The rule that weights them was settled on 22 September 2026 and is set out on [how we rate](/methodology). Placement on this guide is paid for; the order of the table is not. Three things this guide cannot do. It cannot watch a venue behave: custody, the route out, who gets in and the record come off pages the venue wrote itself; silence costs points without proving anything. It cannot price your trading: the fees here are what a new account pays, before volume tiers and rebates. And only BTC was read, so anything narrower is thinner than it looks.
