# Wallet Installation and Connection

## **EVM Wallet Installation**

* Download and Install MetaMask: <https://metamask.io/download/>
* Secure Your Wallet: After installation, be sure to **safely store your seed phrase and private key** to ensure your wallet’s security.

**Interface Guide:** These images below provide an overview of the MetaMask interface.

#### **How to Bridge BTC from other EVM Chains to Merlin Chain**

1. Transfer your BTC from a CEX to Arbitrum, BNB Chain, or any other supported chains.
   1. &#x20; Note: CEXes do not support direct deposits or withdrawals to Merlin right now.
2. Visit [Meson](https://meson.fi/) or [other third-party bridges](https://docs.merlinchain.io/merlin-docs/user-quick-start/how-to/bridge/third-party-bridge) to swap the BTC you have transferred before to Merlin Chain.

## **BTC Wallet Installation**

For Layer1 Cross-chain Purchases, you have to create a new wallet on BTC Layer1. Here we take UniSat as an example.

1. **Download and Install the Wallet**&#x20;

   Visit [Unisat.io](https://unisat.io/) and click "Download" to install the wallet extension.

After installation, pin the extension to your browser and open the wallet.

2. **Create a New Wallet**&#x20;

   Follow the prompts to create a new wallet. Be sure to **securely save your seed phrase and password**; if lost, they cannot be recovered, and your assets will be permanently inaccessible.

   3. **Change the Wallet Address Type**&#x20;

      Click the gear icon in the bottom right corner of the wallet, go to "Address Type," and select "Taproot Address" (which starts with "bc1p"). The settings should look like the image below.

      4. **Withdraw BTC to Your Layer 1 Wallet**&#x20;

         Buy BTC on an exchange like Binance or OKX and withdraw it to your Layer 1 wallet through the exchange’s app under "Funds" -> "Withdraw." Withdrawals typically take 15 to 30 minutes to process, so please be patient.

#### **Cross-Chain Transfer from BTC Layer 1 to Merlin Chain**

1. Go to the Merlin Official Bridge: Visit <https://merlinchain.io/bridge>.
2. Connect Your Layer 1 Wallet.

3. Select the Transfer Amount: On the cross-chain bridge, enter the amount of BTC you want to transfer, then click "Cross-Chain."

   **Note:** Avoid transferring all your BTC to Layer 2 at once, as this may cause the transaction to fail. It’s recommended to keep some BTC in reserve for Gas fees.
