Account Abstraction
ERC-4337 standard that upgrades simple wallets into smart contract wallets with programmable logic.
Account Abstraction removes the complexity of crypto. It allows TUC users to pay gas fees in any token (e.g., paying for a coffee with coffee tokens), recover lost accounts via social recovery, and batch transactions. It is the key to user experience parity with Web2.
