Ethereum Fusaka Upgrade Imposes 16.7M Gas Limit

Published: 2025-10-23 03:23:54 |

Ethereum’s upcoming Fusaka upgrade enacts EIP-7825 to impose a per-transaction gas limit of 2^24 (≈16.78 million). This Ethereum gas limit, set below the block cap, cuts denial-of-service risks and boosts block packing predictability. It has already activated on Holesky and Sepolia testnets, with mainnet rollout after Fusaka. Developers must split large calls and update gas estimation tools. All major clients (Geth, Erigon, Reth, Nethermind, Besu) support the change. The cap prepares the network for EIP-7928 parallel execution, proto-danksharding, enhanced rollup capacity and future danksharding, improving overall efficiency without altering throughput.

Neutral

The Fusaka gas cap is a technical improvement with minimal direct effect on ETH demand or supply. In the short term, traders can expect a neutral price response as throughput remains unchanged. Over the long term, network efficiency and DoS resilience may support Ethereum’s fundamentals, but this preparatory step is unlikely to drive significant price movements alone.
