Variational
PROS
- + No maker or taker fees on any market; the only fixed charge is 0.1 USDC per deposit or withdrawal, and deposits, withdrawals, and logins need no ETH for gas
- + 561 perpetual markets on October 4, 2026 (Omni stats API), including equities, gold, oil, FX, indices, and pre-IPO markets such as OpenAI and Anthropic
- + Tight quotes on majors: the BTC bid-ask for a 100,000 dollar order was about 12 dollars wide near a price of 85,290 dollars (roughly 0.014%) on October 4, 2026
CONS
- − The Omni Liquidity Provider is the only counterparty to every trade and is funded by the Variational team; the docs state that if OLP became insolvent, profit owed to traders would be treated as bad debt and could go unpaid
- − Zero fees do not mean zero cost: the median base spread across listed markets was about 13 basis points on October 4, 2026, far wider than the 1.4 basis points quoted on BTC
- − Still a private beta in October 2026: an access code is required, API trading is not enabled, limit orders fill all-or-nothing, and there is no native mobile app
Aster
PROS
- + Up to 1001x leverage on BTC/USD in 1001x mode (250x on ETH, 75x on other crypto, 200x on forex), the highest advertised leverage among the perp DEXes compared on this site
- + 0% maker fee on all perpetual markets since February 2, 2026, a 0.04% base taker fee on crypto perpetuals, and a 5% discount when fees are paid in ASTER
- + 590 perpetual markets, including US and Hong Kong stock perpetuals with up to 50x leverage and a flat 0.0125% taker fee
CONS
- − 1001x leverage on BTC/USD is extremely risky: a price move of roughly 0.1% against the position liquidates it, and profit on 1001x trades is capped at about 300%
- − Prohibited in 11 named jurisdictions including the US, UK, and Canada, and the Terms & Conditions forbid circumventing location restrictions
- − Founding team is pseudonymous, with limited public disclosure of the cap table and of who holds smart-contract upgrade keys
