This article discusses the importance of full-chain account abstraction in EIP-4337 and proposes some optimization directions. Firstly, Biconomy provides a more detailed standard for EIP-4337 and allows third-party developers to implement modules with similar features but different details. Secondly, it references the concept of EIP-6900 to optimize smart accounts in more detail, addressing the fragmentation issue within the ecosystem. Additionally, the article mentions Particle Network's modular Smart Wallet-as-a-Service (Modular Smart Wallet-as-as-Service) product, which will provide developers with a more flexible and convenient way to build multi-chain applications and promote the widespread adoption of account abstraction.
