- Ethereum’s Fusaka Upgrade: Smartphones Now Directly Sign Transactions with Built-In Security
- Lower Gas Fees and Simplified Wallets: Fusaka Hard Fork Makes Ethereum More Accessible
- Ethereum’s Scalability Boost: PeerDAS and Expanded Block Capacity Ready for 2026
Ethereum’s Fusaka upgrade is set to go live on December 3, 2025. This upcoming hard fork will introduce significant changes, simplifying Ethereum’s interaction with users while improving performance. The Fusaka upgrade promises to address long-standing issues like high gas fees and scalability. It aims to make Ethereum transactions more accessible through mobile devices, marking a shift towards easier blockchain adoption.
EIP-7951: Direct Mobile Transactions
Ethereum’s Fusaka upgrade introduces EIP-7951, a proposal that allows smartphones to directly sign Ethereum transactions. With this feature, smartphones can use built-in security chips, such as Apple’s Secure Enclave, to sign transactions without needing external devices. This change eliminates the reliance on hardware wallets for most users, streamlining Ethereum’s user experience.
This update also reduces gas fees dramatically. Previously, gas fees could reach up to 500k, but now they drop to as low as 6,900 gas units. By lowering costs, Ethereum makes transactions more affordable and accessible to a wider audience, including those new to blockchain technology. Users will find this new system especially appealing, as it simplifies the process while maintaining security.
Simplified Wallets and Enhanced Security
Another key feature of the Fusaka upgrade is the elimination of seed phrases for Account Abstraction (AA) wallets. Instead of the traditional 12-word seed phrase, users will authenticate transactions with Face ID or fingerprint recognition. This shift makes Ethereum more user-friendly, particularly for those unfamiliar with the complexities of seed phrases.
The Fusaka upgrade brings bank-grade security directly to users’ smartphones. The security chips integrated into mobile devices provide the same level of protection as dedicated hardware wallets, such as Ledger or Keystone. This change lowers barriers for users hesitant to adopt Ethereum due to security concerns, offering a safer and more convenient alternative to traditional wallets.
Improved Scalability and Reduced Costs
Ethereum’s Fusaka upgrade will enhance the network’s scalability with the introduction of PeerDAS. PeerDAS allows validators to verify data without downloading full blocks, reducing the computational and storage burden. This feature improves the efficiency of Ethereum’s network and makes it easier to support Layer 2 solutions like rollups, which can process transactions at lower costs.
Additionally, Ethereum’s block capacity is expanding with this upgrade. A larger block size will help reduce congestion, particularly during periods of high network demand. This change is crucial for improving Ethereum’s throughput, allowing the network to handle more transactions without raising fees.
Ethereum’s Path Forward: A Game-Changer for Blockchain
The Fusaka upgrade promises to be a significant milestone in Ethereum’s evolution. It combines user convenience with improved technical performance, bridging the gap between traditional mobile users and blockchain technology. With better scalability, lower costs, and enhanced security, Ethereum is better positioned to handle increasing global demand for decentralized applications.
Ethereum’s adoption is poised for rapid growth as this upgrade brings blockchain technology to the masses in a way that is intuitive and easy to use. By using smartphones for transaction signing and reducing the complexity of wallets, Ethereum makes it simpler for everyday users to engage with the blockchain. This upgrade is a crucial step forward for Ethereum as it prepares for a more scalable and user-friendly future in 2026 and beyond.
