Creating and Selling Premium Prompts

Premium prompts let creators monetize their expertise. The content is encrypted using Lit Protocol - buyers purchase a license to decrypt and use it.

Why Premium?

Not all prompts should be free:

  • Expert knowledge took years to develop
  • Specialized prompts serve niche audiences
  • Creators deserve compensation for valuable work
  • Premium content funds continued development

How It Works

Creator → Publish → Encrypt → IPFS
                      │
                      ▼
Buyer → Purchase → License Receipt (ERC1155)
                      │
                      ▼
Buyer → Decrypt → Full Prompt Content
  1. Publish - Creator encrypts and uploads content
  2. Purchase - Buyer pays SXXX and receives a license NFT
  3. Access - License holder decrypts content via Lit Protocol

Publishing Premium Content

Prepare Your Content

Create a high-quality prompt in a local file:

cat > ./trading-strategy.md << 'EOF'
---
title: Advanced Trading Strategy Prompt
description: Professional trading analysis with risk management
---

You are an expert trading analyst. When analyzing a position:

1. Evaluate market structure and trend
2. Identify key support and resistance levels
3. Calculate risk/reward ratios
4. Suggest position sizing based on account risk
5. Define entry, stop loss, and take profit levels

Always emphasize risk management and capital preservation.

Publish with Price

sage personal premium publish trading-strategy \
  --file ./trading-strategy.md \
  --price 25 \
  --name "Advanced Trading Strategy" \
  --description "Professional trading analysis with risk management"

This command:

  1. Encrypts your prompt with a symmetric key
  2. Uses Lit Protocol to gate the key (only license holders can decrypt)
  3. Uploads encrypted content to IPFS
  4. Registers the listing in PersonalMarketplace contract

Publishing Options

sage personal premium publish my-prompt \
  --file ./prompt.md \
  --price 50 \
  --name "My Premium Prompt" \
  --description "A detailed description" \
  --metadata ./metadata.json \
  --policy 0 \
  --lit-network datil-test

Options:

  • --price <sxxx> - Price in SXXX tokens (required)
  • --file <path> - Path to your prompt content (required)
  • --name <name> - Display name
  • --description <text> - Description for marketplace
  • --metadata <file> - Additional JSON metadata
  • --policy <n> - Fork policy (0=open, 1=gov_only, 2=disabled)
  • --lit-network <name> - Lit network (datil-test or datil-dev)

Pricing Your Content

Prices are set in SXXX tokens:

Price Range Typical Use
5-25 SXXX Simple prompts, templates
25-100 SXXX Domain expertise, workflows
100-500 SXXX Premium strategies, systems
500+ SXXX Enterprise, consulting-grade

Protocol fee: 10% goes to the protocol treasury.

Buying Premium Content

Check Price

sage personal premium price 0xCreatorAddress trading-strategy

Output shows:

  • Base price
  • Protocol fee (10%)
  • Total cost

Purchase

sage personal premium buy 0xCreatorAddress trading-strategy \
  --max-price 30 \
  --auto-approve

Options:

  • --max-price <sxxx> - Maximum you're willing to pay
  • --auto-approve - Automatically approve SXXX allowance
  • --unlimited - When auto-approving, approve unlimited allowance
  • --deadline <seconds> - Transaction deadline (default: 600)

What Happens on Purchase

  1. SXXX transfers from your wallet to creator (minus protocol fee)
  2. You receive an ERC1155 license receipt token
  3. The token proves ownership and enables decryption

Accessing Purchased Content

Decrypt and View

sage personal premium access 0xCreatorAddress trading-strategy

This:

  1. Checks your license receipt ownership
  2. Contacts Lit Protocol nodes to verify
  3. Decrypts the symmetric key
  4. Fetches and decrypts the content

Save to File

sage personal premium access 0xCreatorAddress trading-strategy \
  --out ./my-trading-strategy.md

Access Options

sage personal premium access 0xCreator key \
  --holder 0xAltAddress \
  --gateway https://ipfs.io \
  --session ./lit-session.json \
  --lit-network datil-test

Managing Your Listings

View Your Listings

sage personal list --mine

View Specific Creator

sage personal list --creator 0xCreatorAddress

Update Price

Create a new listing with updated price (original licenses still work):

sage personal premium publish trading-strategy-v2 \
  --file ./updated-strategy.md \
  --price 30

Remove Listing

sage personal premium unlist trading-strategy

This sets the price to 0, preventing new purchases. Existing licenses still work.

Viewing Your Licenses

See what premium content you've purchased:

sage personal my-licenses

Options:

sage personal my-licenses \
  --holder 0xAddress \
  --limit 50 \
  --json

License Receipts (ERC1155)

License receipts are semi-fungible tokens with special properties:

  • Transferable - Can sell or gift your license
  • Provable - On-chain proof of purchase
  • Composable - Other contracts can check ownership
  • Perpetual - Access doesn't expire

Check ownership:

PersonalLicenseReceipt.balanceOf(buyer, promptId) > 0

Encryption Details

Sage uses hybrid encryption combining AES-256-GCM and Lit Protocol:

  1. Encryption - Content encrypted locally with AES-256-GCM symmetric key
  2. Key gating - Lit Protocol gates the symmetric key with access conditions
  3. Access condition - Must own the ERC1155 license receipt
  4. Decryption - Lit nodes verify ownership and release key; content decrypted locally

This means:

  • Content is encrypted at rest on IPFS
  • No central server holds decryption keys
  • Creator doesn't need to be online for buyers to decrypt
  • License ownership is on-chain and verifiable

For a complete technical deep-dive including data structures, flows, and implementation details, see the Encryption Architecture Reference.

Free vs Premium Strategy

Many creators use a hybrid approach:

Tier Content Price
Free Basic prompts, templates 0
Free Community contributions 0
Premium Expert workflows 25-100 SXXX
Premium Domain-specific systems 100-500 SXXX

Free content builds audience; premium content monetizes expertise.
