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
Lighter
PROS
- + Zero maker and taker fees for standard accounts on perpetual and spot markets; premium accounts pay 0.004% maker and 0.028% taker, falling to 0.0028% and 0.0196% with 500,000 LIT staked (30% discount)
- + Every order match, liquidation, and settlement is proven with ZK circuits on Lighter's own Ethereum rollup, and nine audit reports for the contracts and circuits are published in the docs
- + 211 active perpetual markets and 10 spot pairs (October 2026), with up to 50x leverage on BTC, ETH, EURUSD, GBPUSD, USDJPY, SPY, and US500
CONS
- − Restricted in the US, Canada, the UK, China, North Korea, Russia, Ukraine, Cuba, Iran, Venezuela, and Syria under the Terms of Service dated December 29, 2025, a list that includes the UK and Canada
- − Standard accounts trade free but with 300ms taker and cancel latency; the 140ms taker latency requires a premium account that pays 0.028% taker
- − Margin collateral beyond USDC is limited to ETH and XAUT at a 70% loan-to-value ratio, with per-user caps of 2,000 ETH and 500 XAUT
