Account Abstraction

Letting a wallet's authorization logic be programmable, rather than fixed to a single private key.

Account abstraction lets a wallet's rules for authorizing transactions be defined by programmable smart contract logic, rather than requiring a single private key signature every time.

This can enable features like recovering wallet access without a seed phrase, requiring multiple approvals, or paying gas fees in a different token — flexibility not possible with a traditional single-key wallet.

Examples

An account-abstraction wallet might let a user recover access through a set of trusted contacts instead of a seed phrase alone.
Account abstraction is a design shift from a fixed authorization rule to programmable authorization logic.
