The majority of crypto users currently use externally owned account wallets that have suboptimal security measures and a lackluster UX.
Account abstraction is a framework to replace externally owned accounts with contract accounts, enabling wallets to have custom programmability and their own logic akin to a smart contract.
Features of smart contract wallets include batched signing, session keys, additional security measures and private key replacement with social recovery.
EIP-4337 aims to implement account abstraction without having to make consensus-layer changes to Ethereum.
