Hyperliquid's HIP3 protocol has experienced rapid growth, facilitating the trading of diverse assets such as stocks, gold, and Pokémon cards. This expansion has led to substantial USDC inflows from Arbitrum, significantly boosting Arbitrum's transaction volume and ecosystem activity. Arbitrum's low bridge latency, minimal gas fees, and robust USDC liquidity have made it the preferred platform for Hyperliquid, which utilizes Arbitrum for stablecoin bridging. The integration between Hyperliquid and Arbitrum enables users to engage in leveraged trading of real-world assets (RWA) on Arbitrum, enhancing cross-ecosystem liquidity aggregation. This strategic partnership positions Arbitrum as a de facto Layer3 for HIP3, underscoring the complementary relationship between the two platforms.
