Extended
PROS
- + 100+ perpetual markets including cryptocurrencies and TradFi assets (gold, oil, EUR/USD, S&P 500, Nasdaq) — rare among perp DEXes
- + Zero maker fees and just 0.025% taker fees, with maker rebates up to 0.013% based on 30-day market share
- + Up to 100x leverage on major crypto pairs including BTC and ETH, among the highest on Starknet
CONS
- − Restricted in the US, Cuba, Iran, North Korea, and Syria — VPN usage to bypass violates the Terms of Use
- − TVL (~$144M) and liquidity remain lower than leading perp DEXes like Hyperliquid, meaning less depth for large positions
- − Starknet L2 has lower adoption than Ethereum L1 or Solana — fewer integrated dApps and wallets
Aster
PROS
- + Industry-leading up to 1001x leverage in Simple Mode on select crypto pairs (BTC, ETH on BNB Chain and Arbitrum)
- + Zero maker fees on USDT perpetuals (taker just 0.04%) plus an additional 5% discount when paying fees with $ASTER, and fee-free stock perpetuals
- + MEV-resistant hidden orders enable whale-size trades without front-running or price impact — unique among major perp DEXes
CONS
- − Maximum leverage of 1001x in Simple Mode is extremely risky — a 0.1% adverse move liquidates a 1001x position
- − Restricted in the US, UK, and Canada — three of the largest crypto markets — with no confirmed timeline for expansion
- − Founding team is pseudonymous with limited public disclosure of the full cap table and smart-contract upgrade key management
