Turn a Regular Wallet into a Smart Account with EIP 7702

EIP-7702 lets existing Ethereum accounts (EOAs) temporarily delegate execution to smart contracts, enabling features like transaction batching, gas sponsorship, and social recovery—all while keeping your original address and history. This guide shows developers how to build a delegation-based smart wallet, covering authorization lists, initialization patterns, storage safety with EIP-7201, and UX improvements. Key limitation: your private key remains the ultimate security risk, as it can override all smart contract protections. EIP-7702 bridges the gap between traditional wallets and full account abstraction without forcing users to migrate to new addresses.
