While Arbitrum excels with its Layer 2 scaling and lower gas fees, it lacks the variety of trading features and liquidity options that Uniswap provides. This functionality makes Uniswap a more versatile platform for traders and liquidity providers.

→ UniswapUniswap: 9X/100. Arbitrum: 7X/100. Uniswap has an extensive ecosystem with integrations across various wallets, DeFi protocols, and analytics platforms, creating a strong trading experience. Although Arbitrum is growing and has some integrations, it doesn't match the widespread adoption and compatibility that Uniswap has achieved. This network gives Uniswap a significant advantage in terms of ecosystem viability.
Scale + limits

Arbitrum’s Layer 2 solution enables it to handle thousands of transactions per second with minimal latency, making it more scalable for growing user demands. Uniswap, being on Ethereum Layer 1, faces limitations regarding throughput and can become congested during high traffic periods. This scalability advantage makes Arbitrum the better choice for future growth and user adoption.
