Arbitrum officially launched the ArbOS 40 upgrade named Callisto on both the Arbitrum One and Arbitrum Nova networks. This update marks a significant advancement by integrating notable features from Ethereum's Pectra upgrade, including:
+ EIP-7702 – Account Abstraction: Allows users to utilize smart wallets more flexibly, paving the way for features such as multi-signature authentication, recovery wallets, and transaction automation.
+ EIP-2537 – BLS Precompiles: Supports BLS (Boneh Lynn Shacham) signatures, enhancing performance and security in applications such as staking, zk-rollups, or consensus systems.
+ EIP-2935 – Block Hash Access: Allows for more efficient and reliable access to recent block hashes, improving transparency and data verification capabilities.
The deployment of ArbOS 40 not only helps Arbitrum keep pace with Ethereum's upgrade roadmap but also enhances the experience for developers and users through better performance and superior scalability.
This is an important step for Arbitrum to maintain its position as the leading Layer 2 in the Ethereum ecosystem.
