Turnkey SDK
Overview
The Turnkey SDK includes functionality to interact with Turnkey in various contexts and ecosystems. It consists of three main NPM package groups.- the Primary Turnkey Web SDK Packages which expose the main functionality required to build Turnkey-powered applications in different web environments
- the Chain/Ecosystem-Specific Signing Packages which expose signers with support for specific ecosystems, built on top of our Web SDK packages
- the Advanced Functionality SDK Packages which exposes lower level functionality that is leveraged by our Primary Web SDK Packages for those with highly-specific implementations looking to use them.
Primary Turnkey Web SDK Packages
The following packages expose the main functionality required to build Turnkey-powered applications. Each package exposes functions, and/or client classes with methods that manage the process of authenticating requests to the Turnkey API in the contexts of a generic browser environment or react client environment, or a server environment. While these higher level packages are the main points of reference to be used while designing and building Turnkey applications, they wrap other packages with lower level functionality which we also expose separately for those who would like to explore them for more specialized use cases. These packages are listed and described below in the Advanced Functionality SDK Packages section. Our main web SDK packages are as follows:| Package | Description | NPM | Changelog | Docs |
|---|---|---|---|---|
| @turnkey/sdk-browser | The @turnkey/sdk-browser package exposes functionality that lets developers build browser based applications that interact with the Turnkey API with different types of authentication. It consists of different clients that enable requests to the API to be authenticated via different auth methods like user sessions, passkeys and iFrames. It also contains methods to manage information and state related to authentication like auth bundles and sessions, retrieving user information and server signing API requests. |  | changelog | Docs |
| @turnkey/sdk-server | The @turnkey/sdk-server package exposes functionality that lets developers build server-side functionality for applications that interact with the Turnkey API with different types of authentication – allowing applications to authenticate users, manage sessions, and perform organizational operations securely and efficiently. It consists of an API Client and API Proxies that enable requests to the Turnkey API to be authenticated with the appropriate credentials. Specifically, the API Client manages requests signed by the user’s authentication details, and the API proxies handle requests signed by the parent organization’s authentication details. Use this package to handle server-side interactions for applications that interact with the Turnkey API. |  | changelog | Docs |
| @turnkey/sdk-react | The @turnkey/sdk-react package wraps the functionality from the @turnkey/sdk-browser package to allow developers to build react based applications that interact with the Turnkey API with different types of authentication. It allows developers to use the same clients exposed in @turnkey/sdk-browser that enable requests to the API to be authenticated via different auth methods like user sessions, passkey and iFrames. It also contains the same methods to manage information and state related to authentication like auth bundles and sessions, retrieving user information and server signing API requests. Use this package when you’re building React-based frontend applications that interact with the Turnkey API. |  | changelog | Docs |
Chain/Ecosystem-Specific Signing SDK Packages
The following packages contain chain or ecosystem specific signers that take some of our Primary Turnkey Web SDK Packages (usually @turnkey/sdk-browser or @turnkey/sdk-server) and add additional support based on the signing process or transaction structure relevant to that specific chain or ecosystem.| Package | NPM | Description | Changelog |
|---|---|---|---|
@turnkey/ethers |  | Turnkey Signer for Ethers | changelog |
@turnkey/viem |  | Turnkey Signer for Viem | changelog |
@turnkey/cosmjs |  | Turnkey Signer for CosmJS | changelog |
@turnkey/solana |  | Turnkey Signer for Solana | changelog |
@turnkey/eip-1193-provider |  | Turnkey-compatible EIP-1193 Provider | changelog |
Advanced Functionality SDK Packages
For those with more specialized use cases, Turnkey exposes it’s lower level-libraries stamping and encryption libraries to be used directly. Note: for most use-cases, these libraries are not meant to be used directly and we encourage working on designing your application mainlyusing our Primary Turnkey Web SDK Packages along with our Chain and Ecosystem Specific SDK Packages as per your use case!Request Stamping
