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
Aster
PROS
- + Up to 1001x leverage on BTC/USD in 1001x mode (250x on ETH, 75x on other crypto, 200x on forex), the highest advertised leverage among the perp DEXes compared on this site
- + 0% maker fee on all perpetual markets since February 2, 2026, a 0.04% base taker fee on crypto perpetuals, and a 5% discount when fees are paid in ASTER
- + 590 perpetual markets, including US and Hong Kong stock perpetuals with up to 50x leverage and a flat 0.0125% taker fee
CONS
- − 1001x leverage on BTC/USD is extremely risky: a price move of roughly 0.1% against the position liquidates it, and profit on 1001x trades is capped at about 300%
- − Prohibited in 11 named jurisdictions including the US, UK, and Canada, and the Terms & Conditions forbid circumventing location restrictions
- − Founding team is pseudonymous, with limited public disclosure of the cap table and of who holds smart-contract upgrade keys
