💳 Account Abstraction is a big new theme in blockchain development. In short, AA allows a regular user wallet to act more like a smart contract. Instead of the user approving simple transactions with their private key, they can set up more sophisticated conditions.

AA allows for use cases that can make blockchain far more accessible. For example, we can arrange for a third party to pay gas on transactions, so users don’t have to keep topping up their wallet. Or we can set up trusted guardians to recover an account if the user loses their private keys.

All of this makes it easier for Web2 users to get started with crypto apps.
