# 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:

  ```

  ```

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

You will need both:

* **USDC (on Base)** → to purchase BLK

**Ways to fund MetaMask:**

* Buy USDC + ETH directly inside MetaMask (card, bank transfer, Apple Pay where supported)
