Robinhood Chain daily fees fell 97% from their September peak as meme-coin trading cooled

Robinhood Chain's daily fee revenue fell roughly 97% from its early September peak, dropping from about $8 million a day to around $230,000 a day by September 16 as the meme-coin trading that had driven the network cooled. The chain went live on mainnet on July 1 as an Arbitrum Orbit layer 2 that settles to Ethereum, so this is the first real demand cycle it has been through.

A separate figure circulating with this story measures something else and should not be read as part of the same trend line. A Bitquery analysis of September 3 found the chain collected $4.5 million in fees that day while paying $398 to settle the batch on Ethereum layer 1, split as roughly $396 in data posting through blobs and about $2 in proving costs. September 3 sits in the middle of the decline rather than at either end of it, so the $4.5 million is neither the peak nor the current run rate, and the $398 is a single day settlement cost rather than an ongoing one.

Taken on its own terms, the $398 figure is the more durable point. It shows the cost structure an L2 operator actually faces: the revenue scales with user activity while the settlement bill scales with data posted, which is why fee collapses of this magnitude compress absolute revenue without threatening the chain's unit economics.

HOOD closed Friday at $119.82, up 9.1% on the session, per our own market data, though nothing in the reporting ties that move to the chain's fee trend. What is worth watching is whether activity on the chain finds a base above the meme-coin trough, since a layer 2 with no organic demand outside speculative cycles is a different asset than one with recurring flow.
