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
BULK
PROS
- + Base taker fee of 0.035% and maker fee of 0% during the Genesis phase, with taker fees down to 0.022% at 4 billion dollars of 14-day volume and maker rebates of up to 0.015%
- + Portfolio margin is the default: margin is calculated on the correlation-adjusted exposure of the whole account, which the docs say can cut requirements for a hedged BTC and ETH position by 30% to 70% against isolated margin
- + Non-custodial: funds sit in a per-user account of a Solana program, withdrawals need a FROST threshold signature from the validator set, and Zellic audited the program in July 2026
CONS
- − Mainnet is invite-only since September 5, 2026: access codes are the only way in for new users, they are single-use and expire weekly, and no date for public access has been announced
- − Only 8 of 22 listed perpetual markets were open for trading on October 4, 2026, there is no spot trading, and USDC on Solana is the only collateral
- − 24-hour volume was about 21 million dollars and open interest about 9 million dollars on October 4, 2026 per the BULK API, and BTC accounted for 14.3 million dollars of that volume
