Aster

Aster is a decentralized perpetuals exchange offering order-book perps on crypto, stocks and commodities, plus a Shield Mode with order privacy, a one-click 1001x mode and spot trading. It runs on Aster Chain, its own privacy-focused layer 1, which announced mainnet in March 2026.

Cost: Order-book perps on general crypto pairs cost 0.04% taker and 0% maker at VIP 1, falling to 0.016% taker at VIP 6. Group B pairs start at 0.1% taker, and RWA perps carry a flat 0.0125% taker. 1001x mode charges 0.08% to open and 0.08% to close plus an execution fee. A $1,000 buy-and-sell costs about $0.80 in Aster fees.

Sign-up perk: Whatever share of the 10% the referrer passes back as a fee discount (for example 5%).
