Smart wallets and local wallets are both types of wallets with different features and functionalities.

Smart wallets are controlled by a smart contract following the ERC-4337 specification. Smart wallets are powered by account abstraction and enable powerful gasless experiences for users. They are managed by a contract account instead of an externally owned account (EOA). For more information on smart wallets, please refer to our smart wallet overview.

Local wallets are a flexible and advanced solution for building fully-featured wallet experiences. They are tied to the user's device and can be exported at a later date. Local wallets offer powerful use cases such as guest mode, invisible wallet experiences, temporary wallets that can be upgraded to EOAs, simple password flow, and more. For more information on local wallets, please refer to our local wallet overview.

When should I choose smart wallets over Embedded Wallets?​

Embedded Wallets and Smart Wallet are powerful when used in combination, but there are certain applications that will benefit more from just one of the wallet options.
