**Instructions for Connecting TON Wallet on Mobile**

In our ETH-TON cross-chain IDO project, you need to connect both an ETH wallet (for IDO staking) and a TON wallet (for claiming tokens). Below is a detailed step-by-step guide on how to connect these wallets using your mobile device.

We support major EVM compatible wallets like TP, Metamask, OKEx, as well as TON official recommended mobile wallets such as Tonkeeper and Tonhub.

**Recommended Devices**

We recommend using an Android device for this process. If you are using an iPhone, we suggest using the OKEx app, which has built-in support for both ETH and TON.

**Using Metamask + Tonkeeper**

Here are the steps to connect the ETH using your Metamask and Tonkeeper in the DApp:

1. **Open the Project Website:** Use the Metamask wallet on your phone to open the Mumubit IDO website and go to the project page. After connecting with ETH and switching to the correct network, you will see the project page. Click the “Connect Wallet” button at the top of the page to start connecting your wallet.

2. **Connect the Tonkeeper Wallet:** After clicking “Connect Wallet,” a connection dialog will pop up. In this dialog, select the Tonkeeper wallet option. If you have installed the Tonkeeper wallet and created an account, the Tonkeeper app on your phone will automatically be opened.

3. **Authorize the Connection:** In the Tonkeeper wallet, you will see a prompt requesting to connect to the Mumubit IDO website. After confirming that the IDO website is correct, click the “Connect Wallet” button.

4. **Switch Back to Metamask:** After the Tonkeeper connection is completed, the page will automatically open the IDO project page in the default browser. At this point, please manually switch back to the Metamask wallet through the multi-task system. (Note: The page opened in the default browser cannot be operated on.)

5. **Confirm Successful Connection:** After returning to the Metamask wallet, you will see that the connection button displays your connected wallet address. This means you have successfully connected to the Tonkeeper wallet.

6. **Check Wallet Information:** In the project sales page section, you will see the connected Tonkeeper wallet address and the current TON balance. Please ensure you have at least 1 TON to pay for gas fees when claiming the project tokens.

**Using OKEx**

The OKEx mobile app has built-in support for the TON blockchain, allowing you to directly connect your wallet through OKEx:

1. **Open the Project Website:** Open the Mumubit IDO website and go to the project page. Click the “Connect Wallet” button at the top of the page.

2. **Connect the OKEx Wallet:** Click to confirm the connection, and the system will automatically connect to the TON wallet built into your OKEx wallet.

3. **Confirm Successful Connection:** After successfully connecting, you will see the OKEx wallet connection icon on the page, indicating that you have successfully connected both the ETH wallet and the TON wallet.

**Notes**

For iPhone users, there may be an issue where Tonkeeper does not automatically open when connecting via Metamask. If this happens, you can take a screenshot of the QR code displayed on the wallet connection page and then select “Recognize QR Code from Image” in the Tonhub wallet to complete the connection.
