# Get started

Connect your wallet to BlockMail & BlockChat and choose a network.

{% hint style="info" %}
**Status: Maintenance mode.** The 4thTech SDK and the BlockMail & BlockChat white-label apps are supported for existing users; no new features are planned. Last release: SDK 0.5.13 (25 Nov 2025).
{% endhint %}

You connect a wallet, accept the terms and pick a network. Then you land on the dashboard. This takes about a minute.

Try it on a testnet first. Testnet funds have no value, so you can learn the app without spending anything real.

## Before you start

* A wallet: MetaMask, Coinbase Wallet, or any wallet that works with WalletConnect.
* Funds for the network you choose, to pay network fees when you sign actions. On a testnet, use that network's faucet.

## Steps

1. Open the app and select **Connect Wallet** on the start page.

{% endhint %}

2. In the **Connect your wallet** dialog, read the Privacy Policy and Terms of Use, then tick **I read and accepted**. The wallet buttons stay disabled until you do.
3. Choose **MetaMask**, **Coinbase Wallet** or **WalletConnect**. Approve the connection in your wallet.

{% endhint %}

4. If your wallet is on a network the app does not support, a **Select supported network** window opens. Pick a network. Your wallet asks you to switch.

   You can also change network at any time from the network button in the top toolbar.

{% hint style="info" %}

{% endhint %}

5. You are on the dashboard. It shows your address, the network and your balance, plus the [Encryptor](/sdk-and-white-label/encryption.md) widget and, if no storage is preconfigured, the [PollinationX](/sdk-and-white-label/storage.md) widget.

## Supported networks

The app supports the 12 networks listed on the [Networks](/sdk-and-white-label/networks.md) page. Mail and chat only work on a network where the OCC v1 contracts are deployed; see the [Deployments page](/home/deployments.md).

## Disconnecting

Disconnect from your wallet or from the account menu in the toolbar. The app returns you to the start page.

## Next

[Set up encryption](/sdk-and-white-label/encryption.md), then [set up storage](/sdk-and-white-label/storage.md).
