Forever Moments - LUKSO Social Platform

Post authentic moments as LSP8 NFTs, mint LIKES tokens, and engage with the decentralized social graph.

Use When / Don't Use When

USE WHEN

• Posting a moment (with or without image)
• Minting LIKES tokens to tip creators
• Creating/joining collections (curated feeds)
• Listing moments for sale
• Automated AI-image generation and posting (cron)

DON'T USE WHEN

• Credentials missing (FM_PRIVATE_KEY, FM_UP_ADDRESS not set)
• User hasn't approved spending LYX for LIKES minting
• Quick test posts without image (use text-only mode)
• Operations on unsupported chains (LUKSO mainnet only)

Quick Commands

# Post text moment
node scripts/post-moment.js "Title" "Description" "tag1,tag2"

# Post with AI image (Pollinations - FREE)
node scripts/post-moment-ai.js "Title" "Desc" "tags" "image prompt"

# Post with AI image (DALL-E 3 - Premium)
node scripts/post-moment-ai.js --dalle "Title" "Desc" "tags" "prompt"

# Mint LIKES tokens (costs LYX)
node scripts/mint-likes.js 0.5

The 4-Step Relay Flow (Gasless)

All operations follow this pattern:

┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│  1. Pin Image   │────▶│  2. Build Tx    │────▶│ 3. Prepare Relay│────▶│ 4. Sign & Submit│
│  (if needed)    │     │                 │     │                 │     │                 │
└─────────────────┘     └─────────────────┘     └─────────────────┘     └─────────────────┘

Code Template

// 1. Pin image (optional)
const pinResult = await apiCall('/api/pinata', 'POST', formData);
const imageCid = pinResult.IpfsHash;

// 2. Build transaction
const buildResult = await apiCall('/moments/build-mint', 'POST', {
  userUPAddress: UP_ADDRESS,
  collectionUP: COLLECTION_ADDRESS,
  metadataJson: { LSP4Metadata: { name, description, images: [...] }}
});

// 3. Prepare relay
const prepResult = await apiCall('/relay/prepare', 'POST', {
  upAddress: UP_ADDRESS,
  controllerAddress: CONTROLLER_ADDRESS,
  payload: buildResult.data.derived.upExecutePayload
});

// 4. Sign raw digest (CRITICAL!)
const signature = wallet.signingKey.sign(ethers.getBytes(prepResult.data.hashToSign));

// Submit
const submitResult = await apiCall('/relay/submit', 'POST', {
  upAddress: UP_ADDRESS,
  payload: buildResult.data.derived.upExecutePayload,
  signature: signature.serialized,
  nonce: prepResult.data.lsp15Request.transaction.nonce,
  validityTimestamps: prepResult.data.lsp15Request.transaction.validityTimestamps,
  relayerUrl: prepResult.data.relayerUrl
});

Negative Examples

❌ WRONG: Using wrong signing method

// WRONG - adds EIP-191 prefix
await wallet.signMessage(hashToSign)

// CORRECT - sign raw bytes
wallet.signingKey.sign(ethers.getBytes(hashToSign))

❌ WRONG: Wrong IPFS endpoint

// WRONG
POST /api/agent/v1/pinata

// CORRECT
POST /api/pinata  (no /agent/v1 prefix!)

❌ WRONG: Missing credentials

// DON'T proceed if env vars not set
if (!process.env.FM_PRIVATE_KEY) {
  throw new Error('FM_PRIVATE_KEY not set - check .credentials');
}

Templates

Post Moment with Image

const metadata = {
  LSP4Metadata: {
    name: "Moment Title",
    description: "Description text",
    images: [[{
      width: 1024, height: 1024,
      url: `ipfs://${cid}`,
      verification: { method: "keccak256(bytes)", data: "0x" }
    }]],
    tags: ["art", "lukso"]
  }
};

LSP4 Metadata Structure

Field	Required	Format
name	Yes	String, max 100 chars
description	Yes	String, max 1000 chars
images	No	Array of arrays with IPFS URLs
icon	No	Single image for thumbnail
tags	No	Array of strings, max 10 tags

Edge Cases

Scenario	Handling
Pollinations rate limit	Wait 60s, retry with backoff
DALL-E not configured	Fall back to Pollinations (free)
IPFS pin fails	Retry once, then fail with error
INVALID_SIGNATURE	Check signing method (raw digest!)
RELAY_FAILED	Verify controller has EXECUTE_RELAY_CALL permission
Collection already joined	Skip join, proceed with post
Cron timeout (180s)	Increase timeout or optimize image generation

Required Environment Variables

# Required for all operations
