Rollup Transactions Exploded After EIP-4844 — But There’s a Catch

Ethereum’s EIP-4844 upgrade significantly boosted rollup transaction volumes across major networks like Base, Arbitrum, and Optimism. While lower fees appear to have encouraged more activity, the impact on settlement speeds is mixed: some rollups, such as Arbitrum and zkSync Era, achieved faster confirmations, while others saw increased delays. The findings highlight both the scaling benefits and operational challenges that remain, especially around predictable settlement times and blob capacity limits.
