EIP-7825 establishes a hard upper bound of 2\u00b2\u2074 gas per transaction to improve block packing efficiency and pave the way for better parallel processing in future execution environments,\u201d the EF wrote.<\/p>\n<\/blockquote>\n<p>    <!-- .cn-block-related-link --><\/p>\n<h2 class=\"wp-block-heading\">What does it mean for users?<\/h2>\n<p>While the gas fee cap limits the amount of gas each transaction can use, its application doesn\u2019t impact overall block gas limit.<\/p>\n<p>The cap also ensures that transaction blocks consist of several smaller and more predictable transactions \u2013 rather than one very large one.<\/p>\n<p>As the change goes live on mainnet, one of the key things to note will be what developers and users relying on very large transactions should do. <\/p>\n<p>Notably, the Ethereum Foundation advises that such users ensure their contracts and transaction builders align with the new cap.<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u201cFor most users, nothing changes. The vast majority of transactions are already well below 16 million gas,\u201d Ethereum Foundation researcher Toni Wahrst\u00e4tter said. \u201cHowever, certain contracts and deployment scripts, particularly those performing batch operations, may exceed this limit. Such transactions will be invalid once Fusaka activates.\u201d<\/p>\n<\/blockquote>\n<h2 class=\"wp-block-heading\">When is Fusaka upgrade?<\/h2>\n<p>The Fusaka upgrade went live on the Sepolia testnet earlier this month, after activation in the Holesky testnet.<\/p>\n<p>Activation on the mainnet is the next step in Ethereum\u2019s push to further boost network scalability and performance.<\/p>\n<p>Fusaka is expected to launch on the mainnet on December 3, 2025. Currently, the Sepolia deployment allows for stress testing of features such as the ones outlined via EIP-7825.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Ethereum\u2019s highly anticipated hard fork Fusaka will activate with a major change to transaction gas limit cap.
