What is account abstraction in crypto wallets?

Account abstraction is a design that lets a crypto wallet be controlled by programmable smart contract logic rather than a single fixed private key. It works by turning the account itself into code, so rules like spending limits, multiple approvers, or alternative recovery methods can be built in. For example, a wallet using account abstraction could require two signatures for large transfers and allow a fee to be paid in a stablecoin instead of the native token. This makes wallets more flexible and recoverable than traditional key-only accounts, while introducing dependence on the underlying contract code.
