• Fusaka Update - Transaction Gas Limit Cap arrives with EIP-7825 Posted by Toni Wahrstätter on October 21, 2025 Research & Development Starting with the upcomingFusakahard fork,EIP-7825introduces aper-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). • This change isalready live on Holesky and Sepolia, and will activate onmainnet with Fusaka. • Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap. • Background As Ethereum scales to higher block gas limits and prepares for parallel execution (e.g.EIP-7928in Glamsterdam), theFusaka forkintroduces a per-transaction gas limit cap. • Previously, a single transaction could consume the entire block gas limit (~45 million gas), creating potential DoS risks and preventing parallel execution.EIP-7825establishes ahard upper boundof 2²⁴ gas per transaction to improve block packing efficiency and pave the way for better parallel processing in future execution environments. • This cap does not affect the overall block gas limit but only restricts how much gas a single transaction may use.

- Starting with the upcoming Fusaka hard fork, EIP-7825 introduces a per-transaction gas limit cap of 2²⁴ (≈ 16.78 million gas). This change is already live on Holesky and Sepolia, and will activate on mainnet with Fusaka. Developers and users who rely on very large transactions should verify that their contracts and transaction builders conform to the new cap.
