Circle's User-Controlled Wallets SDKs allow for the integration of user-controlled wallets within your client applications. The SDKs support various authentications methods to ensure a seamless user experience while using the wallet.
Note:
Circle's User-Controlled Wallets SDKs simplify client-side development and are not required for developer-controlled wallets.
To build client applications that enable secure, user-controlled wallets, you must use one of Circle's User-Controlled Wallets SDKs. Circle supports the following platforms:
The User-Controlled Wallets SDKs securely manage and communicate with your server, ensuring that users' keyshares remain exclusively with them and are never exposed to your server. To maintain security, the SDKs encrypt all request bodies using an encryption key. This guarantees that users retain full control over their digital assets in the wallet, with no access to funds by either Circle or your application.
You initialize the SDK by setting the endpoint server. This allows your application and Circle’s API platform to communicate. To simplify the development of your application, you can use the corresponding server-side Node.js SDKs or Python SDKs.
Your server retrieves challengeId
from
Circle's API platform
and passes it to the SDK, which then executes relevant operations. Certain
operations may differ based on the authentication method with which you choose
to integrate, for example:

You can customize the styling, layout, and description of your UI modals, including:
For detailed instructions on customizing UIs for web, iOS, and Android, see the following docs:
Circle provides the following client-side web SDK to enable integrations with Circle’s prebuilt UI components to create user wallets securely, send transactions and more.
Circle provides the following client-side mobile device SDKs to help you create native applications for iOS and Android devices and platforms. Mobile SDKs support only user-controlled wallets.
