EIP-7907 proposes raising Ethereum’s smart contract size limit to 256 KB, enabling more complex dApps and innovations.
To prevent abuse, contracts over 24 KB will incur extra gas fees, aligning scalability with network resource fairness.
Ethereum is preparing for a significant step in its development roadmap with the proposed EIP-7907. The upgrade, titled “Meter Contract Code Size And Increase Limit,” is part of Ethereum’s upcoming Fusaka hardfork, scheduled for late Q4 2025. The upgrade aims to change how developers interact with the network by lifting a long-standing barrier on smart contract size.
EIP-7907 would raise the contract size ceiling from its current limitation to 256 kilobytes, a substantial increase that can allow more complex applications to be deployed. The change doesn’t simply open the door to heavier contracts but does so in a way that preserves network stability. Contracts larger than 24 kB will now incur a charge of two gas per word, a solution meant
