forever-moments（永远的时刻）

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');
}
