How NFT Creation Works

Understanding the technical process behind Stork SMS’s unique conversation NFT system

Understanding the technical process behind Stork SMS’s unique conversation NFT system.

The NFT Creation Process

Step 1: Starting a New Conversation

When you initiate a new chat on Stork SMS:

1. Message Composition: Write your first message and optionally select a sticker
2. Recipient Selection: Enter the recipient’s Solana wallet address
3. Preview Generation: See a preview of your NFT design
4. Transaction Confirmation: Approve the 0.0033 SOL transaction in your wallet

Step 2: Dual NFT Minting

Once you confirm the transaction, Stork SMS creates two NFTs simultaneously:

Sender NFT

• Visual Design: Features “You started a conversation with [recipient]”
• Recipient: Sent to your wallet address
• Purpose: Proves you initiated this conversation
• Access Rights: Grants you access to view and send messages

Recipient NFT

• Visual Design: Features your actual message content and any selected sticker
• Recipient: Sent to the recipient’s wallet address
• Purpose: Proves they received this conversation invitation
• Access Rights: Grants them access to view and reply to messages

Step 3: Blockchain Recording

Both NFTs are minted as compressed NFTs (cNFTs) on Solana:

• Network: Solana blockchain (Mainnet or Devnet)
• Standard: Metaplex compressed NFT format
• Storage: Metadata stored on distributed storage
• Verification: Ownership verified on-chain

Technical Architecture

Image Generation

Each NFT features custom-generated artwork:

Canvas Specifications

• Resolution: 1080x1080 pixels
• Format: PNG with transparency support
• Rendering: Server-side canvas generation
• Optimization: Compressed for fast loading

Design Elements

1. Base Frame: Theme-specific background design
2. Message Text: Your actual message rendered with custom typography
3. Wallet Identifiers: Abbreviated sender/recipient addresses
4. Timestamp: Conversation creation date
5. Sticker Overlay: Optional sticker graphics
6. Branding: Subtle Stork SMS branding elements

Metadata Structure

Each NFT includes comprehensive metadata:

{
  "name": "Stork Message #abc123",
  "symbol": "STORK",
  "description": "A verified message NFT created on Stork SMS",
  "image": "https://r2.stork-sms.net/nft-images/...",
  "attributes": [
    {
      "trait_type": "Message Type",
      "value": "Text"
    },
    {
      "trait_type": "Theme",  
      "value": "Default"
    },
    {
      "trait_type": "Character Count",
      "value": "42"
    }
  ],
  "message": {
    "content": "Hello! How are you?",
    "sender": "ABC123...",
    "recipient": "XYZ789...",
    "timestamp": "2025-08-15T10:30:00Z"
  }
}

Access Control Integration

Ownership Verification

Before showing any chat messages, Stork SMS:

1. Checks Wallet Connection: Verifies user’s connected wallet
2. Queries Blockchain: Checks NFT ownership for the requested chat
3. Validates Access: Confirms user owns either the sender or recipient NFT
4. Grants Access: Displays encrypted messages if verification passes
5. Denies Access: Shows “Access denied” if no NFT ownership found

Real-Time Monitoring

The system continuously monitors NFT ownership:

• Transfer Detection: Notices when NFTs are sold or transferred
• Access Updates: Immediately updates chat access permissions
• New Owner Notification: Alerts new owners about their chat access
• Previous Owner Lockout: Removes access from previous owners
