Ethereum recently unveiled its upcoming roadmap's \textit{Splurge} phase,
highlighting the integration of
EIP-\hlhref{https://eips.ethereum.org/EIPS/eip-3074}{4337} as a foundational

advancements in accounts, wallets, and standards related to its development. We
step further by conducting a preliminary security evaluation to qualitatively
assess the extent of security enhancements achieved through AA updates
