Account abstraction is a blockchain feature that allows smart contracts to be treated as accounts, enabling more flexible and advanced wallet options, improving security measures, and enhancing the overall user experience (UX).
On Starknet, a layer-2 scaling solution built on top of Ethereum, account abstraction is integrated into the protocol. This means that Starknet permits the execution of transactions solely through smart contract accounts. By implementing a Smart Wallet utilizing account abstraction on Starknet, users can enjoy more advanced and customizable wallet options, which can improve their account security and overall experience on the platform.
This feature allows for capabilities such as genuine 2FA (e.g.: Hardware Signer) and 3FA, spending limits for accounts, and built-in paymaster support for paying gas fees with any ERC-20 token.
