Overview
Account Abstraction as defined by ERC-4337, "allows users to use smart contract wallets containing arbitrary verification logic instead of EOAs as their primary account." ERC-4337 introduces many user experience benefits, most notably enabling people to use Smart Contracts as their primary accounts.
Here is a quick explanation:

As a developer, you gain the following benefits:
- 1.Easily sponsor's your user's transaction.
- 2.Batch multiple actions insto single tx. Example, Uniswap requires first approval pool and then another for actual swap. With Account abstraction, both of them is just 1 transaction.
- 3.Allow users to pay in different ERC20 tokens.
- 4.Login/Logout users, sign messages without them having to deploy smart wallet.
