# Common use cases

> How partners apply C8 Wallet SDK — what it is, who it's for, and the business value it delivers.

## What it is

C8 Wallet SDK is a ready-made integration layer that allows third-party applications to connect their users to **C8 Wallet** on the Canton network.

It gives partner applications a secure and familiar way to work with wallet-based user approvals, Canton assets, and transaction flows — without building wallet infrastructure from scratch.

## Why it matters

For most teams, building a wallet layer is expensive and operationally sensitive. It requires:

* Authentication flows
* User approval screens
* Transaction signing
* Wallet state handling
* Network-specific logic

<Check>
  C8 Wallet SDK removes that complexity. Partners can focus on their product experience while C8 Wallet handles the wallet interaction layer.
</Check>

## Who it is for

The SDK is designed for development teams building applications that need Canton wallet connectivity.

## How partners can use it

Partners can embed C8 Wallet connectivity directly into their own application experience. A user can:

<Steps>
  <Step title="Connect their wallet" />

  <Step title="Review available assets" />

  <Step title="Approve actions" />

  <Step title="Follow transaction progress" />
</Steps>

— all while staying inside the partner product journey.

The SDK is the right fit when an application needs to support wallet-based actions but does **not** want to own private key management, transaction signing, or direct Canton ledger communication.

## Business value

<Check>
  C8 Wallet SDK helps partners **launch Canton-enabled products faster**, **reduce integration risk**, and **provide users with a trusted wallet experience** backed by Cantor8 infrastructure.

C8 Wallet acts as a plug-in wallet layer for partner applications.
