Self-custodial
Account Abstraction takes away the complexity of having to use both externally-owned accounts (EOAs) and smart contracts, and unifies them together.
Self-custodial wallets are now a reality, with an additional layer of enhanced security.
Ecosystem
Behind the scenes lies ERC-4337, the industry-advocated proposal to allow and upgrade Account Abstraction (AA) on to the Ethereum network.
The ultimate goal is for the entire ecosystem to be able to achieve full account abstraction, a dream for many years.
Censorship
The core focus of ERC-4337 is to enable and advocate for censorship resistance.
Account abstraction allows for zero sacrifice on decentralization, which was a very hard problem to solve all this while.
