Darkroom · x402

High-fidelity RAW photo collaboration where every layer adjustment, filter application, and version fork requires a 0.01 USDC micro-settlement. Eliminate subscription bloat; editors pay only for the compute and storage they consume, while creators earn instantly as collaborators 'unlock' high-res assets for retouching. Final exports are signed and settled on-chain.

The primitive.

full primer →

Access to the collaborative editing engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so photographers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy turning the 'edit' action into a billable event, the platform solves the 'freeloader' problem in creative workflows. It creates a granular ledger of who touched which pixels, using x402 to meter professional-grade cloud rendering and IPFS pinning.

Snapshot Proof · x402
A high-frequency copyright layer for the screenshot era. 0.01 USDC per EIP-712 signature to timestamp image hashes on Hedera. Creators meter every license issuance, and platforms pay to verify provenance in real-time. No subscriptions, just provable ownership on-demand.
image authenticity
TrueLens · x402
A pay-per-seal protocol for photographers. Every shutter click or metadata injection requires a 0.01 USDC micro-settlement to anchor the image's SHA-256 hash and geolocation to Base. Instead of a subscription, users pay only for 'Truth-as-a-Service,' generating a cryptographically verifiable 'Proof of Origin' receipt. Protect your IP and verify reality in an era of Deepfakes, one cent at a time.
