According to U.Today, Toyota Blockchain Lab has referenced Ethereum’s ERC-4337 standard in its recent publication titled “How to Introduce Mobility into the Public Blockchain.” The work focuses on integrating Mobility-Oriented Account (MOA) with Ethereum's Account Abstraction standard ERC-4337. Sota Watanabe, founder of Astar Network, a Toyota partner, announced the development on social media, highlighting the involvement of large Japanese enterprises in public blockchain initiatives.

Toyota Blockchain Lab introduced the Toyota Mobility Concept in April 2023, aiming to integrate mobility with social systems under the “Mobility 3.0” framework. The lab identified public blockchains as a viable option to achieve this vision, leveraging the ability to share states with a large audience. The concept of a smart account on the blockchain, referred to as a Mobility-Oriented Account, is central to this initiative. Toyota aims to design MOA based on the ERC-4337 standard in the Ethereum ecosystem, which is expected to enhance programmability and functionality.

The protocol believes that integrating ERC-4337 can address several challenges associated with traditional approaches, such as the loss of private keys and limited blockchain functionality. Account Abstraction, a key feature of ERC-4337, separates the authentication process from key management. This means that losing a private key does not necessarily result in the loss of the account, allowing for safer and more flexible account management. Additionally, Toyota plans to explore the use of the CREATE2 opcode defined in EIP-1014, which enables the deterministic setting of an address before the account is deployed.
