Robinhood Chain raised its gas limit and reduced user fees to expand capacity and meet strong demand for block space, causing chain revenue to fall sharply. DefiLlama data showed about $403,000 in chain revenue and $448,600 in fees over the past 24 hours, compared with $1.81 billion in DEX volume. Seven-day DEX volume exceeded $12.77 billion, up nearly 23%. Dragonfly managing partner Haseeb Qureshi said the network was solidly second behind Solana, while Uniswap founder Hayden Adams said the fee decline reflected capacity expansion rather than weakening demand. About 95% of the network's DEX volume runs through Uniswap. Critics including Solana Labs cofounder Anatoly Yakovenko argued that low fees could leave Robinhood with a low-margin business while benefiting rival front ends. Robinhood Chain, which launched on July 1, has more than $937 million in total value locked and over $1 billion in stablecoins, with USDG accounting for more than 68% of the stablecoin supply. Uniswap earns a 0.465% fee on each dollar traded on the network, while the chain returns 10% of net protocol revenue to Arbitrum, split between the DAO treasury and a developer fund. Standard Chartered forecast ARB at $10 by the end of 2030 and said Robinhood Chain had helped lift Arbitrum's monthly revenue run rate to about $5 million.
