Overlay Origin · ucp

Protect original graphic overlays by minting each as immutable NFTs with creator attribution. Discovery and checkout collapse into a single deterministic round trip, every request and response signed with RFC 9421 HTTP Message Signatures and settled in HBAR or HTS USDC — a storefront an agent can transact against without a browser.

Section · Onchain

The primitive.

full primer →

The onchain primitive runs at the right moment in the flow and surfaces a clear, verifiable result that videographers can act on without web3 jargon.

Why this primitiveUCP is what agentic commerce looks like once the haggling is gone: a fixed-price, machine-verifiable checkout where a tampered byte is rejected outright rather than warned about, and the receipt is a Hedera transaction.

Kernel
an agent-to-agent negotiation loop — A2A 0.3 JSON-RPC tasks carrying AP2 Intent / Cart / Payment mandates, or a UCP signed checkout under RFC 9421 — settled with x402 in HBAR or HTS USDC on Hedera testnet and, where authorisation itself is on-chain state, bound by a bespoke mandate-vault contract verified on HashScan
Drives the UI as
an agent flow log that shows the offer, the counter, the signed cart, the mandate check and the settled payment, every artifact linked to HashScan

FrameRate · x402
A high-fidelity asset library for editors where every graphic overlay—from 4K film grains to lower-thirds—is metered. Stop buying $300 bundles you only use 2% of. Instead, pay 0.01 USDC per asset import directly into your timeline via HTS transfer. Each micro-license is a Hedera transaction id, ensuring creators get paid for every single frame-set pulled into a project.
video copyright
FrameChain Auth · a2a
Verify and timestamp original video frames onchain to prove authentic content ownership instantly. Two agents — a buyer acting for the artist and a seller acting for the rights holder — negotiate this over A2A 0.3 tasks and settle the agreed price in HBAR or HTS USDC, with every turn of the conversation receipted on Hedera.
edit history
EditVersion Ledger · ap2
Track and verify every edit version of a video project transparently on the blockchain. The buyer's agent states an IntentMandate with hard caps, the seller answers with a signed CartMandate, and a PaymentMandate carries the Hedera settlement hash back — so an autonomous purchase leaves a signed, auditable trail from intent to receipt.
