The Ethereum Foundation has announced that the upcoming Fusaka hard fork will introduce a significant change with EIP-7825, setting a per-transaction gas fee cap at approximately 16.78 million gas. This update, already active on the Holesky and Sepolia testnets, will be implemented on the Ethereum mainnet with the Fusaka hard fork. Developers and users handling large transactions are advised to ensure their contracts and tools are compatible with this new limit.
