Conclusion

Lighter occupies a conservative niche in the perpetual DEX market, focusing on Arbitrum ecosystem traders who prefer moderate 20x leverage over the extreme 100x-1001x offered by competitors. While its $200M daily volume is dwarfed by AsterDEX's $32B or Hyperliquid's $9B, Lighter's innovative order matching engine and capital-efficient margin system provide unique value for its target audience.

Best for: Conservative Arbitrum/Ethereum ecosystem traders who prioritize lower liquidation risk (5% move vs 0.1% at 1001x) and want professional trading tools without extreme leverage. Ideal for traders already active in Arbitrum DeFi looking for perpetual futures access.

Not recommended for: Traders seeking maximum leverage, deep liquidity for large positions, zero gas fees, or fastest execution speeds. For these needs, AsterDEX or Hyperliquid are objectively superior choices.

Final verdict: Lighter is a solid option for its specific niche but doesn't compete with major platforms on leverage, volume, or features. Consider it if you're committed to Arbitrum ecosystem and want conservative perpetual futures trading. Otherwise, explore AsterDEX (for leverage) or Hyperliquid (for proven reliability and zero gas).
