EVEDEX vs Aster in 2026

Neither venue collects documents to trade. Aster connects a wallet with a signature (Aster docs, checked 18 September 2026), and its terms and conditions state that it may implement limited identity verification procedures to comply with applicable regulations (Aster terms, checked 18 September 2026). That is a reserved right without a described mechanism: it may never be used, and a trader cannot tell in advance.

The other venue takes the opposite approach to disclosure. EVEDEX states that it does not operate traditional KYC systems and that it relies on automated AML screening of on-chain behaviour with on-chain behaviour analysis, plus activity monitoring (stated in the EVEDEX documentation, 18 September 2026). The check is not smaller — it runs on every deposit — but a trader can read what it is before sending funds.

One further difference decides whether a venue is listed on this site at all, and it is worth stating before the columns below are read. Aster's own onboarding documentation sets out a second way in: a six-digit email code and a password, which generates a wallet that accepts USDT on Arbitrum. That is a door the register here does not admit, so Aster is entered in none of the rankings and appears only on this page. A head-to-head is a comparison, not a register, and the pair is printed because readers ask for it — not because both sides cleared the same test.

A new Aster account pays 0% maker / 0.040% taker, which leaves a maker with nothing to pay and prices a $10,000 taker round trip at $8.00. The hybrid's 0.015% maker / 0.045% taker does not shift with volume either; what happens instead is that a portion of what has already been paid comes back, on a base percentage rising through a gamification level any user can climb, with five flat points added for Prime subscribers — 35% of the trader's own fees at full stretch (stated in the EVEDEX documentation, 18 September 2026).

In our snapshots the BTC books were close, $15.9 million within 10 basis points on Aster against $17.9 million on EVEDEX, with a $100,000 market order moving the price 0.39 bps and 2.06 bps respectively.

Aster lists 578 perpetual markets against 52 on the hybrid, and both span six asset classes. The difference is when they are open: EVEDEX states that all of its markets trade around the clock, including shares, FX and commodities (stated in the EVEDEX documentation, 18 September 2026).

Underneath, Aster's matching has moved onto a chain of its own, where the core contracts and the RPC layer stay unpublished and validator seats are not open to outsiders in phase one (Aster Chain overview, checked 18 September 2026). EVEDEX matches orders off-chain and pushes position data down to Arbitrum once enough of it has accumulated, and again on every withdrawal (stated in the EVEDEX documentation, 18 September 2026). For a trader trying to leave, the two end up in the same place: neither writes down an exit that works without the operator, which is what holds their custody marks at 5.0 and 7.0.

Aster suits a trader who wants the widest market list and a zero maker fee, and who is comfortable with a chain run by one operator in its current phase. The hybrid suits a trader who wants gold, oil, FX and equity exposure on the same USDT balance at any hour, and who prefers a venue that publishes what it does with deposits. Neither offers spot markets, options or a fiat off-ramp.

Not one of these figures was requested from a venue. The sign-up page, the terms of use behind it, the fee schedule, the market list — each quoted as it stood on 18 September 2026, and where a marketing line and a contract disagree the contract is what gets printed. All 2 venues here are marked against one rubric, set down on 21 September 2026 before any had been read. Depth is the exception: nobody publishes it usefully, so each venue's public BTC book was opened here and sampled on 19 September 2026, ten minutes between readings, beginning just after midnight UTC. No account was registered, no order sent.

Which venues were eligible to be marked at all is settled before any of that, by the one test this desk applies: the sign-in a venue's own onboarding pages document has to be a signature from a wallet the trader already holds, with no email account, no social login and no wallet the venue opens for them behind it. EVEDEX, Extended, Lighter and Aevo meet it and carry an order book we could sample. The admission test names the venues it keeps out, and the front-page door count is where a reader can check the sorting venue by venue.

Silence in a column is not a clean finding: a venue that writes nothing about screening is recorded as having written nothing. Every door and every custody line above is a venue describing itself, in a document it wrote and may rewrite, and one address on one day can be asked for more than any page here records.

Two narrower ones. Depth was read on BTC books alone; fee columns carry the rate a new account is charged, nothing taken off.
