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
Avantis
PROS
- + Zero-Fee Perpetuals: no opening, closing, or borrowing fees on losing trades — only a 2.5-10% profit share on winning positions
- + Fixed-fee perps cost just 6 bps (0.06%) opening and closing on BTC/ETH/SOL, and 8 bps (0.08%) on altcoins
- + 90+ markets from one account: 60+ crypto pairs plus 18+ forex pairs, commodities (gold, silver, WTI, Brent), indices (SPY, QQQ) and MAG7 equities
CONS
- − Single-chain deployment on Base only — traders on other networks must bridge assets in
- − USDC is the only accepted collateral, so holders of other stablecoins must convert first
- − Oracle- and keeper-based execution means dependency on Chainlink feed reliability during extreme volatility
