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
Extended
PROS
- + 326 active perpetual markets: 195 crypto and 131 real-world asset markets, including 112 equities plus gold, oil, FX and stock indices
- + 0% maker fee and 0.025% taker fee on crypto markets, 0.010% taker fee on RWA markets, and maker rebates up to 0.010% for a 30-day market share of 5% or more
- + Multi-asset collateral: USDC counts at 100% of its value toward margin, USDT at 95%, and wBTC, ETH and XVS vault shares at 90%
CONS
- − Restricted in the United States, United Kingdom, Canada, Russia, Hong Kong, Seychelles and sanctioned countries (Cuba, Iran, North Korea, Syria); the Terms of Use forbid using a VPN to bypass this
- − BTC and ETH leverage is capped at 50x, and the 100x maximum applies only to the EUR/USD market
- − TVL of about 122 million dollars and 24-hour volume of about 181 million dollars are well below the largest perp DEXes, which means less depth for large orders
