Lit Client Setup

Configure the Lit Protocol client for the Lit JS SDK

See the Lit Client Reference API for more details on how to create a Lit Client.

Overview

The Lit Client is the core interface for interacting with the Lit Protocol network.

1. Install the SDK

   Run the following command to install the SDK and the required viem peer dependency:

   npm

   npm i @lit-protocol/lit-client @lit-protocol/networks viem
   

   viem is not bundled with the SDK. Ensure your application supplies a compatible version.

2. Network Configuration & Client Creation

   Choose the appropriate network based on your development stage and requirements, then create your Lit Client instance.
