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
Velocity
PROS
- + Trading is open again: the public beta has been available to all users since September 21, 2026, with BTC, ETH and SOL perpetuals at up to 20x leverage and HYPE at up to 10x
- + Makers receive a 0.0025% rebate on post-only orders at every volume tier, and the taker fee falls from 0.06% to 0.02% above 200 million dollars in 30-day volume
- + One cross-margin account accepts USDT, SOL, wBTC and wETH as collateral, and deposits earn lending interest while they back positions
CONS
- − About 286 million dollars was stolen on April 1, 2026 through compromised administrator keys, and verified user losses are about 295.4 million dollars
- − Affected users have recovered about 1 percent so far: each DFX recovery token redeemed for about 0.0104 USDT from a 3.11 million USDT pool in early October 2026
- − The relaunched exchange lists four perpetual markets, down from more than 40 before the exploit, and spot order book trading was removed
