Ethereum Foundation: The Fusaka hard fork will introduce a transaction gas limit cap through EIP-7825

ChainCatcher message, the Ethereum Foundation stated in an official blog post that with the upcoming Fusaka hard fork, EIP-7825 introduces a cap on the GAS fee for each transaction, set at 2 to the power of 24 (≈ 16.78 million gas). This change has been deployed on the Holesky and Sepolia testnets and will be activated on the mainnet during the Fusaka hard fork.

Developers and users relying on large transactions should verify that their contracts and transaction building tools comply with the new cap requirements.
