Overview
- EIP-7825 sets a hard 2^24 gas ceiling per transaction, with the Ethereum Foundation confirming activation in the Fusaka hard fork.
- The cap leaves the ~45M block gas limit unchanged but prevents any single transaction from filling a block, reducing DoS risk and improving packing.
- Holesky and Sepolia already enforce the limit, providing environments for teams to validate workloads before mainnet activation.
- Developers using large batch operations or pre-signed high-gas transactions are advised to split work or re-sign to stay within the new threshold.
- Major clients including Geth, Erigon, Reth, Nethermind, and Besu have shipped Fusaka-ready updates, with mainnet rollout reported for December 3, 2025.
