​
The Asset

Audience Inventory is the end product of the 555x402 flywheel. It turns ephemeral “attention” into a durable, tradable asset.

​
Technical Standard: cNFTs

We utilize Compressed NFTs (cNFTs) on Solana via the Metaplex Bubblegum program. This allows us to mint millions of inventory items for fractions of a penny, making high-volume attention tracking economically viable.

​
Merkle Tree Structure

Inventory is stored in a concurrent Merkle Tree on-chain.
  • Max Depth: 24 (16M items).
  • Canopy Depth: 14 (Fast verification).

​
Metadata Schema

Every unit of Audience Inventory adheres to a strict JSON schema, ensuring interoperability with advertisers. We enrich this data with Social Context.

Bespoke Targeting

Advertisers can use this rich metadata to buy Verified Airtime that matches their exact niche.

​
3. Utilization (Yield)

Advertisers do not manually “buy” individual items. Instead, they plug in to verified inventory sources programmatically.
  1. The Stream: The Creator streams content, generating verified inventory (cNFTs).
  2. The Plug: Advertisers set criteria (e.g., “Sector 13, >1000 viewers”).
  3. The Yield: When criteria match, the protocol automatically routes the ad to the stream.
  4. The Payout: The Creator earns yield (USDC/$555) instantly for every second of verified airtime.
No manual sales. No negotiation. Just stream and earn. This allows brands to target Micro-Communities with surgical precision, paying creators directly for the quality of their audience, not just the quantity.

​
Market Dynamics

  • Floor Price: Determined by the “Cost of Attention” (e.g., $0.01 per minute).
  • Rarity: High-reputation users or high-score sessions command a premium.
  • Liquidity: Inventory can be bundled and sold in bulk (e.g., “1000 hours of FPS gameplay”).
