How it works

Agents that pay for consent: A2A for the conversation, HSP for the payment, HSK Chain to enforce the terms.

  1. 1

    Terms on chain

    The creator's price per render, allowed uses, regions, cap and maximum duration live in CreatorRegistry. Political, adult and deceptive uses are banned in the contract.

  2. 2

    A2A request, a licence bundle

    The brand's payment agent finds the creator's agent from its A2A card and asks once: one brief, N images, M videos. On chain that's one licence per media type: images at the creator's price, videos at 3×.

  3. 3

    HSP order

    For each render the creator's agent calls HSP's create_order (merchant Likeness), paid to the creator's payout.

  4. 4

    Policy check

    The brand's agent checks the order: the payee is the creator's payout, the price fits her terms and the brand's budget, the licence is active.

  5. 5

    Approval 1, then sign

    prepare_payment returns the authorization to sign. A person approves (recipient, payer, token_total_raw), and the brand wallet signs exactly that EIP-712, unchanged.

  6. 6

    Approval 2, then submit

    finalize_payment returns the payment mandate. A person approves again; submit_payment hands it to HSP, which settles it on HSK Chain.

  7. 7

    Status

    The creator's agent follows query_payment until payment-safe or payment-finalized, with HSP's attribution check.

  8. 8

    Recorded, then the receipt

    HspSettlement records the payment only after it checks the brand's authorization executed on chain; the render agent anchors the file's sha256 in ReceiptAnchor.

  9. 9

    Revoke

    The creator revokes in one click. The brand's agent reads the licence first, so the next payment is refused before any order, signature or payment.
