ERC-4337

ERC-4337 is an Ethereum standard that introduces the concept of “account abstraction,” enabling more flexible and user-friendly cryptocurrency wallet management. It allows users to utilize “smart accounts,” which offer features like account recovery, batch transactions, and the ability to authorize transactions without needing ETH to cover fees.

The key advantage of ERC-4337 is that it operates without requiring changes to the Ethereum protocol—everything is handled through smart contracts. This means users are no longer dependent on traditional EOA (Externally Owned Accounts) wallets, simplifying blockchain interactions and paving the way for innovations such as Google account logins or multi-level wallet permissions.
