# Overview - For App Developers

> Distribute your dApp across Web3 wallets

<Note>
  **This guide is for you if:**\
  You're building a dApp and want to:

  * Get listed in Intersend's ecosystem
  * Distribute your app and reach crypto users through partner wallets
</Note>

Intersend is a non-custodial app store for crypto apps that enables seamless Web3 interactions through a unified experience. The fundamental goal is: **make it simple for your app and your users to connect, sign, and transact**.

The integration enables seamless communication between your app and Intersend through:

* **Auto Connection**: Automatically connects user's wallet with your app on page load with SIWE authentication
* **Message Relay**: Handles transaction signing, message signing, and contract interactions through event listeners
* **Non-Intrusive**: Only activates when your app is accessed through Intersend, preserving your existing functionality

Below is a high-level guide for dApps that want to be listed in Intersend and auto-connect with users’ wallets via Intersend.

***

## Key Concepts

### Connectors

A “connector” is a small integration layer that allows Intersend to inject a user’s wallet/account into your dApp. We support multiple connector approaches, including:

* **Safe Connector** (common in Wagmi-powered apps)
* **Custom connectors** for:
  * [Privy](https://intersend.mintlify.app/apps/privy)
  * [Dynamic](https://intersend.mintlify.app/apps/dynamic)
* Other authentication providers are in progress (Thirdweb, web3-onboard, Magic, Web3Auth, etc.) or can be integrated similarly.

If your dApp already has a Safe Connector enabled in Wagmi, you’re effectively compatible with Intersend’s “Safe flow” right away. Otherwise, check our [Privy Guide](https://intersend.mintlify.app/apps/privy) or [Dynamic Guide](https://intersend.mintlify.app/apps/dynamic) for more specific integration steps.

### iFrame & Event Listeners

Intersend loads your dApp within an iframe, and sends/ expects events to:

1. **Auto-connect** the user’s wallet/account
2. **Relay transactions** for user signatures
3. **Share** signed data, chain switches, and transaction confirmations back to your dApp

Because of this, you may need to **whitelist Intersend’s domain** so your site can be embedded in an iframe and to allow cross-domain communication.

## How It Works

    participant User
    participant Wallet as Wallet App
    participant Intersend as Intersend
    participant App as Your App


    Note over User,Wallet: Load & Browse Apps
    User->>Wallet: Opens Explore Tab of the Wallet
    Wallet->>Intersend: Fetch list of available apps
    Intersend-->>Wallet: Returns app list

    Note over User,App: Launch Selected App
    User->>Wallet: Selects an app
    Wallet->>Intersend: Loads app in iframe
    Intersend->>App: Wraps your app within Intersend interface
    Intersend->>Wallet: REQUEST_WALLET_INFO
    Intersend->>App: WALLET_INFO (address, chainId)

    Note over User,App: Transaction Flow
    User->>App: Initiates transaction (e.g. purchase, swap)
    App->>Intersend: eth_sendTransaction (RPC request)
    Intersend->>Wallet: Constructs, and sends tx data
    Wallet->>User: Prompts user to approve transaction
    User->>Wallet: Approves
    Wallet->>Wallet: Signs & broadcasts to blockchain
    Wallet->>Intersend: Returns txHash (RPC response)
    Intersend->>App: Send success or fail
    App-->>User: Shows success/fail message
```

### Get Listed Once integrated, contact us for review and approval:
