# Terms and conditions of sale: Integra Lens Merch Shop

Version 4. Effective: 2026-10-03.

These are the terms on which Integra Lens Merch Shop sells at https://integra-lens-merch-live.demos.integraledger.net. Each purchase makes its own agreement, which holds these terms' address and hash.

## 1. This is a demonstration

For demonstration only. This transaction runs on a test network with test money, and has no value.

Every sale here is fully executed when it is made: the agreement is issued and bound to the payment, the payment is made on Base Sepolia (`eip155:84532`), a test network, in its test USDC (`0x036CbD53842c5426634e7929541eC2318f3dCF7e`), and what is sold is delivered as section 6 says. Nothing here is sold for money of any value.

Prices are real-life prices in US dollars, excluding sales tax or VAT, and the prices stated here hold until 2026-12-31. In this demonstration each is paid at one millionth of a USDC for each cent: $28.00, paid as 0.0028 USDC.

## 2. The parties

- The seller: Integra Ledger, Inc., trading as Integra Lens Merch Shop, at https://integra-lens-merch-live.demos.integraledger.net. Contact: legal@integraledger.com.
- The buyer: whoever pays for an offer here, through an agent of their own or one they use. The buyer is known by the wallet that signs the payment.
- The payee: every payment for a purchase here is made to Integra's treasury, `0x4F098166790DeaBb92c2Ef4516D8C1ab88A12C6B`, on Base Sepolia (`eip155:84532`), Integra's own account on the rail. It needs no proof: it is Integra's own account on Base Sepolia, the treasury Integra's demonstrations are paid to. Each agreement names the payee in its `order` (`paid.payee`, and in words `paid.words`), and Integra's facilitator settles a payment only to the payee of the agreement the payment carries.

## 4. How an agreement is made

- When a buyer asks to buy, before any payment, Integra's appliance issues an agreement for that purchase: an Agreement Transaction Record (ATR). It holds the seller, the offer, these terms (the offer's word for word, and this document by its address and SHA-256), the order and its price, what the buyer gave, and what this demonstration will and will not do.
- The payment request carries the agreement's hash, H, which is the SHA-256 of its exact bytes, and a link to those bytes, in the x402 extension `legalContext`. An agent should fetch the link, hash the bytes, and compare the result with H before it signs.
- The payment is bound to H. For an offer paid when bought, and for pay later's anchoring payment (x402 `exact`), H is the nonce of the EIP-3009 authorization; for an offer authorised now and collected later (x402 `auth-capture`), H is in the escrow payment's salt. The same offers are offered through MPP too (the `evm` method's `authorization` credential), under an agreement of their own: its challenge's `id` is base64url of its H and the challenge's position, its `opaque` names H, and the EIP-3009 authorization's nonce is keccak256 of the id and the realm. A payment that carries H is the buyer's acceptance of that agreement.
- An agreement can be paid once, while it is open: 15 minutes from its issue. A signature is good for 300 seconds.
- Where an offer is open to negotiation, a price agreed with the seller's agent stands for 10 minutes, for one purchase, named as the quote.
- Every offer also has a test checkout, at `/test/buy/<offer>` and as the tool `test_buy`. A checkout for testing your agent. The hash it advertises has one character changed. An agent that checks signs nothing. Nothing is sold here.

## 5. Payment

- Paid when bought: an EIP-3009 transfer of the amount, in test USDC, to the payee, `0x4F098166790DeaBb92c2Ef4516D8C1ab88A12C6B`, settled by Integra's facilitator (https://x402.demos.integraledger.net).
- No fee is charged beyond the price.
- A payment is said to be paid only once the seller's own reading of the chain confirms it.

## 6. Delivery

Each purchase is delivered once, at its inception, after its payment settles: for an offer authorised now and collected later, after it is authorised into escrow; for pay later, after the anchoring payment settles.

- A file is delivered in the answer to the paid request, and only then. The buyer can check it against the SHA-256 the agreement names.
- An order is recorded at its own address. The order is recorded and the stock is reduced. Nothing is sent.

## 7. Records

- Each purchase has a proof page, at `https://integra-lens-merch-live.demos.integraledger.net/proof/<H>`, which shows the agreement, the appliance's record of it, and the payment on the chain.
- The appliance records a transaction at its inception: the agreement, and the payment bound to it. What follows, such as the collection of a payment authorised into escrow, is the seller's own reading of the chain. For pay later, the amount owed is neither tracked nor collected: the record is of the agreement and its anchoring payment.

## 8. No warranty

Everything here is provided as it is, for demonstration, with no warranty of any kind.

## 9. Changes to these terms

These terms are served at https://integra-lens-merch-live.demos.integraledger.net/terms.md. Their SHA-256 is published as `atrHash` in https://integra-lens-merch-live.demos.integraledger.net/.well-known/legal-context.json. If they change, their version and the day it took effect, above, change, and so does their hash; an agreement already made holds the address and hash of the terms it was made under.
