Robinhood Chain's 90-day gas subsidy ended September 29, revealing a stark monetization problem: despite $1.6B DEX volume and $919M perpetual volume in 24 hours, chain fees dropped 98% to $166K daily compared to $4.01M before the subsidy ended. The data shows applications capture 8x more revenue than the chain itself, raising questions about whether the ecosystem has real demand or was merely subsidized behavior.
