Catalog

Browse and mint Pokemon cards from the complete Gen 1 collection.

---

Overview

The Catalog displays all 151 Generation 1 Pokemon. Each Pokemon can be minted exactly once as a unique NFT card.

---

How It Works

1. Browse Pokemon

The catalog shows all 151 Pokemon with:

• Sprite image
• Name and ID
• Type(s)
• Base stats (HP, Attack, Defense)
• Calculated rarity

2. Check Availability

Pokemon are marked as:

• Available - Can be minted
• Minted - Already exists as a card (shows current owner)

3. Mint Card

Click an available Pokemon to mint it as your NFT card:

1. Confirm the transaction in MetaMask
2. Wait for blockchain confirmation
3. Card appears in your inventory

Rarity System

Rarity is calculated from base stats:

Score = HP + Attack + Defense

Tier	Name	Score Range	Example
1	COMMON	< 150	Magikarp (100)
2	UNCOMMON	150-199	Pikachu (130)
3	RARE	200-249	Charizard (227)
4	LEGENDARY	>= 250	Mewtwo (286)

Rarity Distribution

Gen 1 Pokemon distribution by rarity:

Rarity	Count	% of Total
Common	~60	40%
Uncommon	~50	33%
Rare	~35	23%
Legendary	~6	4%

Data Source

Pokemon data comes from PokeAPI:

• Official sprites
• Accurate base stats
• Type information
• Names in multiple languages

---

Metadata Storage

When you mint a card, metadata is stored on IPFS:

{
  "name": "Pikachu #25",
  "description": "A Rare Pokemon trading card.",
  "image": "ipfs://QmImageCID",
  "attributes": [
    { "trait_type": "Type", "value": "Electric" },
    { "trait_type": "HP", "value": 35 },
    { "trait_type": "Attack", "value": 55 },
    { "trait_type": "Defense", "value": 40 },
    { "trait_type": "Rarity", "value": "RARE" },
    { "trait_type": "Value", "value": 130 }
  ]
}

This ensures your card's data persists even if 5BLOCK goes offline.

Limitations

• Max 4 cards per wallet - You cannot mint if you already own 4 cards
• One per Pokemon - Each Pokemon can only be minted once globally
• Gas required - Minting costs gas (SepoliaETH on testnet)
