EIP-3074 is an upgrade for normal Ethereum wallets that adds some smart wallet functionality. It was slated for inclusion in the next Ethereum upgrade. After it was approved, Vitalik Buterin and other Ethereum researchers expressed concern about compatibility between 3074 and 4337 (standard smart contract wallet) wallets and the potential of 3074 to be broken by quantum computers. EIP-7702 fixes both of these issues.
