# BLK Token Presale Guide

***

### 1️⃣ Get a Wallet

To participate in the presale, you need a crypto wallet that supports Ethereum-compatible networks. We recommend:

* **MetaMask** (primary recommendation)
* Trust Wallet
* Coinbase Wallet

👉 Write down your **seed phrase** and keep it secure. Never share it.

***

### 2️⃣ Connect to Base Mainnet

BLK is launching on **Base**, Coinbase’s secure Ethereum L2.

* In MetaMask → Go to **Networks → Add Network**
* Use Chainlist to add **Base Mainnet** automatically
* Confirm your wallet is set to **Base**

***

### 3️⃣ Add the BlackChain Token (optional for viewing)

* Open your wallet
* Go to **Import Token**
* Add the contract address:

  ```
  0x1D10cDCBFFc12B05a3ddD895219BC21e788aB242
  ```

***

### 4️⃣ Fund Your Wallet (You Need **USDC + ETH**)

You will need both:

* **USDC (on Base)** → to purchase BLK
* **ETH (on Base)** → to pay for gas fees

**Ways to fund MetaMask:**

* Buy USDC + ETH directly inside MetaMask (card, bank transfer, Apple Pay where supported)
* Withdraw from Coinbase or another exchange (select **Base network**)
* Bridge from Ethereum mainnet using Base Bridge

***

### 5️⃣ Go to the Presale Portal

1. Visit: <https://presale.blackchain.io>
2. Connect your wallet (on **Base Mainnet**)
3. Select the amount of BLK you want to purchase
4. Pay with **USDC** (gas in ETH)
5. Confirm the transaction in MetaMask ✅

***

### 6️⃣ Token Allocation & Vesting

* Your BLK tokens will be locked in the presale smart contract
* Vesting: **6-month gradual release schedule** *(update if different)*
* BLK will appear in your wallet once tokens go live

***

### 7️⃣ Stay Updated

* 📢 Join our Discord
* 📰 Subscribe to the BlackChain Newsletter
* 🎥 Follow Market Overview calls for updates

***

✨ **Quick Recap**:

* Install MetaMask → Connect to **Base**
* Fund with **USDC (to buy)** + **ETH (for gas)**
* Use the official **Presale Portal** to purchase BLK

***

This way you keep the **step-by-step simplicity** you loved while also including:

* **Base Mainnet setup**
* **USDC for purchases**
* **ETH for gas**
* **Contract address for token import**

***

✨ **Reminder:** The presale is the only official way to secure BLK tokens early. Always double-check links to avoid scams. **BlackChain Token (BLACK)**
