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
dYdX
PROS
- + Base tier perpetuals fees of 0.05% taker and 0.01% maker, falling to 0.025% taker and a -0.011% maker rebate at 200 million USD of 30-day volume
- + Staking discount on trading fees: 3,000 staked DYDX cuts base tier fees by 25%, and 20,000 staked DYDX cuts them by 50%
- + Onchain governance by DYDX token holders controls fees, market listings and rewards, with 75% of protocol fees directed to DYDX buybacks
CONS
- − Low liquidity in 2026: 24-hour perpetuals volume was about 3 million USD on October 4, 2026, and the active market count fell from 114 to 73 in three months as governance wound down low-activity markets
- − 50x leverage is available only on BTC and ETH; SOL is capped at 20x and the other 70 markets at 5x or 10x
- − Perpetuals are restricted in the US, UK and Canada, so US traders can only use the Solana spot product
