Enable illustrators to sell artworks with embedded gasless framing add-ons and easy wallet login. 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.

Section · Onchain

The primitive.

full primer →

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

Why this primitiveAP2 turns 'the agent bought it' into three signed artifacts a human can audit: what was asked for, what was offered, and what was actually paid — each bound to a Hedera transaction anyone can open on HashScan.

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

digital framing services
Lume · x402
Gallery-grade digital matting and AR framing as a metered service. Creators embed a 'Lume' call into their mints; collectors pay $0.01 USDC per viewing session to render the piece in a high-fidelity, environment-aware digital frame. No monthly subscriptions for collectors—just a penny to see the art properly dressed for the screen.
art ownership tracking
Provenance Palette · a2a
Securely track and prove the ownership lineage of paintings with tamper-proof blockchain records. 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.
generative art minting
Generative Mint Studio · ap2
Artists can mint unique generative art pieces directly onto Hedera testnet with automated smart contracts. 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.
