Will Fusaka Keep Users on L2? Upcoming Ethereum Upgrade Eyes up to 60% Fee Cuts

Why It Matters

Lower fees could curb the exodus to competing L2s and keep more activity on Ethereum’s main chain, strengthening its economic security and attractiveness to developers and users alike.

Summary

The next Ethereum upgrade, dubbed Fusaka—a blend of the consensus‑layer "Fulu" and execution‑layer "Osaka"—will revamp how the network processes data and calculates fees, targeting fee reductions of up to 60 percent while leaving the user‑facing experience unchanged. By shifting data handling to the base chain, Fusaka reaffirms Ethereum’s role as the ultimate settlement and data‑availability hub, even as most daily transactions continue on layer‑2 solutions. The change is a backend optimisation rather than a protocol overhaul, aiming to improve scalability and cost efficiency without disrupting existing applications.
