Robinhood Chain's Unlikely Dominance in Ethereum Layer 2

Robinhood Chain has generated $50.2 million in transaction fees from September 1 to 23, accounting for 57.3% of Uniswap's total protocol revenue during that period. This is a remarkable feat for a network that only went live on July 1.

The chain's rapid ascent into the upper tier of Ethereum Layer 2 ecosystems has been driven by memecoin traders, not institutional investors as initially expected. At its peak in early September, Robinhood Chain was generating approximately $8 million per day in transaction fees, which would annualize to nearly $3 billion.

However, the revenue bonanza didn't last long. Per-transaction fees plummeted from 64 cents to under 3 cents by mid-September, a decline of 97%. Despite this, the volume of actual transactions remained healthy, with weekly DEX volume on the chain staying near $12 to $13 billion during peak activity periods.

The explanation for the fee drop lies in Robinhood's decision to subsidize gas fees for eligible swaps through September 29. The chain also operates under a revenue-sharing arrangement with Arbitrum, paying 10% of net revenue to the Orbit stack provider.
