EIP-7702
Overview
Enhances the functionality of Externally Owned Accounts (EOAs) by enabling them to temporarily adopt smart contract capabilities during transaction execution. Bridges the gap between EOAs and smart contracts, facilitating advanced features without necessitating a complete overhaul of the existing Ethereum infrastructure.

Applications
Batch Transactions
Users can bundle multiple operations into a single transaction, improving efficiency and reducing costs.
Sponsored Transactions
EOAs can utilize paymaster contracts to cover gas fees, enabling transactions without holding native ETH.
Advanced Security Features
Incorporation of multi-factor authentication, social recovery mechanisms, and issuance of sub-keys with limited permissions.
Innovative Use Cases
The ability for EOAs to execute smart contract code opens avenues for creating more dynamic and user-friendly decentralized applications (dApps).
