Ethereum Foundation Announces Gas Limit Cap for Upcoming Fusaka Upgrade

Why It Matters

By enforcing predictable transaction limits, Ethereum is positioning the network for higher throughput and safer scaling as it moves toward parallel execution.

Summary

The Ethereum Foundation said it will introduce EIP‑7825 with the Fusaka hard fork in December, imposing a per‑transaction gas cap of 16.78 million (down from the current ability for one transaction to consume a full 45 million‑gas block). The cap is already live on Holesky and Sepolia testnets and is intended to reduce Denial‑of‑Service risks and make transaction sizes more predictable to enable future parallel execution. The change should have little effect on typical users but will require developers who batch transactions or use large contracts to test and adjust tooling and deployments.
