Aster
PROS
- + Industry-leading 1001x leverage on BTC/USD in Simple Mode (250x on ETH, 75x on other crypto, 200x on forex) — the highest publicly advertised leverage of any major perp DEX
- + 0% maker fees across all perpetual markets (since Feb 2, 2026) and just 0.04% taker on USDT perps (0.005% on USD1 perps), plus a 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 1001x leverage on BTC/USD is extremely risky — a roughly 0.1% adverse move liquidates a 1001x position
- − Restricted in 11+ jurisdictions including the US, UK, and Canada per its Terms & Conditions — and using a VPN to bypass the restrictions violates the terms
- − Founding team is pseudonymous with limited public disclosure of the full cap table and smart-contract upgrade key management
Extended
PROS
- + 110+ perpetual markets combining cryptocurrencies with TradFi assets (gold, oil, EUR/USD, S&P 500, Nasdaq) — rare among perp DEXes
- + Zero maker fees and just a 0.025% taker fee, 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, UK, Canada, Russia and sanctioned countries (Cuba, Iran, North Korea, Syria) — using a VPN to bypass violates the Terms of Use
- − TVL (~$137M) 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
