# Wallet SDK Download

> Download and install the Canton Network Wallet SDK for building wallet integrations

The Wallet SDK provides TypeScript/JavaScript libraries for interacting with Canton Coin and the Canton Network Token Standard. Use it to build wallet applications, integrate Canton Coin payments into your dApp, or manage external party signing workflows.

The SDK is published as the [`@canton-network/wallet-sdk`](https://www.npmjs.com/package/@canton-network/wallet-sdk) npm package. Source code and the OpenRPC specification for the dApp API are available in the [wallet-gateway repository](https://github.com/canton-network/wallet-gateway).

## Installation

The Wallet SDK is published on the npm registry. Install it with your preferred package manager:

<Tabs>
  <Tab title="npm">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    npm install @canton-network/wallet-sdk
    ```
  </Tab>

  <Tab title="yarn">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    yarn add @canton-network/wallet-sdk
    ```
  </Tab>

  <Tab title="pnpm">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    pnpm add @canton-network/wallet-sdk
    ```
  </Tab>
</Tabs>

### dApp SDK

For dApp development only, the dApp SDK has a smaller bundle size and is optimized for browser usage. Both SDKs share the same underlying core packages, and individual core packages (transaction visualization, hash verification) can be used independently.

<Tabs>
  <Tab title="npm">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    npm install @canton-network/dapp-sdk
    ```
  </Tab>

  <Tab title="yarn">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    yarn add @canton-network/dapp-sdk
    ```
  </Tab>

  <Tab title="pnpm">
    ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
    pnpm add @canton-network/dapp-sdk
    ```
  </Tab>
</Tabs>
