The project consists of several subfolders located in the packages directory:

• [keychain](packages/keychain) - a sandboxed application hosted at

https://x.cartridge.gg/ and responsible for sensitive operations, such as

signing transactions. When an application requests to sign or execute a

transaction, keychain enforces client side authorization logic and displays UI

for user approval if necessary and responsible for displaying the state of

Controller account, such as token balances, activities, and achievement.

• [controller](packages/controller) sdk. Controller implements the account

interfaces required by [starknet.js](https://github.com/0xs34n/starknet.js).

Underneath, the implementation communicates with an embedded sandboxed

keychain iframe.

Frontend

Install pnpm via corepack:

```sh

corepack enable pnpm

```

Install dependencies:

```sh

pnpm i

```

Run Controller with examples:

```sh

pnpm dev

```

This command builds all workspace dependencies first and start these servers:

• http://localhost:3002: Controller Example (Next.js)
• http://localhost:5174: Controller Example (Svelte)
• http://localhost:3001: Keychain
• http://localhost:3003: Profile

The simplest way to then develop with your cartridge account is to port it over

from the production keychain:

• Login to your account at https://x.cartridge.gg/login
• Open your console, dump your account with window.cartridge.exportAccount()

and copy it

• Visting your local keychain at http://localhost:3001/
• Load your account into your local keychain

```js

window.cartridge.importAccount("EXPORTED ACCOUNT");

```
