# Blockchain Integration

### 🔧 Account & Wallet Options

**Signup Flow:**

* **Option #1 (Email/Password)**
  * Traditional account created with option to link Algorand and Immutable wallet.
* **Option #2 (Immutable Passport)**
  * IMX wallet is automatically linked.
* Note: Players may add both Algorand and Immutable wallets at any time.

**Wallet Linking:**

* When a TCG player links an Algorand wallet, the system auto-creates a Fracctal Monsters (FM) web profile.
* Users can then log into the FM website by connecting their Pera Wallet.

### 🎨 NFT Integration

#### 🏰 NFT Forging System

* Cards can be leveled up to 25.
* At level 25, players can spend CORE to forge the card as an NFT.
* Forging resets the card’s level.
* Each additional NFT minted for a card increases the fee globally.
* Forged NFTs have a golden frame and show in both the card view and board view.
* Forged cards appear in the FM site inventory and can be traded on the FM marketplace.\\
