Terms of Service

Effective July 2026 · Version 1.0 · These terms govern your use of the Minthouse platform.

§1 · Acceptance & eligibility

These Terms of Service are an agreement between you and Minthouse Markets, Inc. (“Minthouse,” “the house,” “we”). By registering, placing a bid, consigning a lot, or otherwise using the Minthouse site and the services offered through it (together, “the platform”), you accept these terms and the Conditions of Sale, which are incorporated into these terms by reference. If you do not accept them, do not use the platform.

• You must be at least 18 years old and legally able to form a binding contract.
• You may not use the platform in any jurisdiction where auctions of collectibles settled in digital assets, or your participation in them, is unlawful. Complying with the laws that apply to you is your responsibility.
• You may not use the platform if you are barred by the sanctions rules in §10.
• If you use the platform on behalf of a company or another person, you represent that you have authority to bind them, and “you” includes them.

§2 · The service

Minthouse operates an auction venue for graded trading cards. In every sale the house acts as agent of the consignor: we catalogue, market, and sell lots on the consignor’s behalf, and unless a lot page states otherwise we do not own the lots we sell. The contract of sale for each lot forms between the winning bidder and the consignor, on the terms of the Conditions of Sale.

Nothing on the platform is investment, financial, tax, or legal advice. Collectibles are not investments. Estimates, bids, and prices realized describe an auction market, not a return: prices can fall, sometimes sharply, and no lot is offered with any expectation of profit.

§3 · Accounts & registration

• The information you register with must be accurate and kept current.
• One person, one account. Additional accounts may be closed without notice.
• You are responsible for the security of your credentials, your email, and any connected wallet, and for everything done under your account. Tell us promptly about any unauthorized use.
• We may decline any registration, and may suspend or close an account, for breach of these terms, suspected fraud or bid manipulation, failed compliance screening, or unpaid invoices. Suspension does not excuse invoices already owed, and lots already closed remain binding under §4.

§4 · Bidding & binding contract

Every bid is an irrevocable offer to purchase the lot at that amount plus the auction house fee and any applicable taxes. Bids cannot be lowered or withdrawn, only raised. A maximum bid authorizes the house to bid for you at the lowest winning price, never above your maximum, under the resolution rules of Conditions of Sale §2.

When a lot closes with a highest bid at or above any reserve (reserves are confidential and never above the low estimate), a contract of sale forms immediately between you and the consignor. The house executes that contract as the consignor’s agent and issues your invoice.

Auction mechanics are governed by the Conditions of Sale: increments, sealed-maximum resolution, extended bidding (a late bid moves the close to five minutes after the bid, anchored to the bid, capped at 30 minutes per lot), and reserve behavior. If these terms and the Conditions of Sale conflict about the conduct of an auction, the Conditions of Sale control. The auctioneer may reject bids that appear erroneous or manipulative.

§5 · Fees & payment

A tiered auction house fee is added to every winning bid: 7.5% on the first $2,500 of the hammer, stepping down to 3.9% above $1,000,000, applied marginally per band as set out in Conditions of Sale §4. Fixed-price Buy Now purchases carry no fee. Invoices are denominated in US dollars, settle in USDC at 1:1, and are payable within 10 days under the settlement mechanics of Conditions of Sale §5.

• Late payment and default. An invoice unpaid after 10 days may be voided, with the lot released. On default we may also suspend your account, cancel the sale, resell the lot, and recover from you any shortfall against the resale price together with our reasonable costs of collection.
• Taxes. Sales and use taxes, customs duties, and any other taxes arising from your purchases are your responsibility. Where the law requires us to collect a tax, it is added to your invoice.

§6 · Digital-asset terms & risk disclosure

Invoices are denominated in US dollars and settle in USDC, which is denominated in dollars at 1:1. Before you bid, understand what that means:

• No conversion. USDC is denominated in dollars, so settling an invoice is not a currency exchange and there is no rate to watch. The invoiced dollar amount governs, as described in Conditions of Sale §5.
• Finality. On-chain transfers are final and irreversible. A payment sent to the wrong address, on the wrong network, or in the wrong asset cannot be recalled, by us or by anyone.
• Your wallet, your keys. You are responsible for the security of your wallet and keys and for verifying the settlement address shown in your account before sending. Settlement addresses are never sent by email.
• Network fees. Blockchain network fees are yours and are not refunded, including on overpayments returned in kind and on requoted or reissued invoices.
• The chains themselves. We do not operate, and are not responsible for, any blockchain, wallet software, or network, including congestion, outages, and forks.

§7 · Third-party onramp

Onramping, meaning converting dollars to crypto to fund an invoice, is provided by Peer Pay, an independent third-party service operating under its own terms. Minthouse is not a party to your relationship with the onramp provider.

• Minthouse does not profit from onramps, holds no customer funds at any point in an onramp, and is not a money transmitter or money services business.
• Disputes about an onramp order, whether failed, delayed, or canceled, lie with the provider under the provider’s terms.
• Onramp orders run $100 – $10,000. Above the cap, the OTC desk introduces you to an independent conversion provider; Minthouse never takes custody of or converts your funds and is not a party to the conversion.
• Using an onramp does not change your obligations on an invoice: the invoice is yours to settle within 10 days regardless of the status of any onramp order.

§7a · Cash-out (offramp)

The cash-out feature converts USDC in your own wallet to a fiat payout in a payment app you name. It runs on the open ZKP2P protocol: your wallet signs a deposit into a public escrow contract on Base, and an independent buyer fills the order by paying your payment-app handle.

• Minthouse never holds, routes, or converts your funds in a cash-out. The escrow is a public smart contract; the deposit, fill, and any withdrawal are transactions you sign from your own wallet.
• Payout details (payment app and handle) are supplied by you and used by the protocol, not by Minthouse. Send-to-the-wrong-handle mistakes cannot be reversed by Minthouse.
• USDC is denominated in US dollars, so a cash-out is not a currency conversion. The amount you receive can fall slightly below the amount you deposit through slippage on the fill. Minthouse adds no fee and earns nothing from cash-outs.
• An unfilled deposit can be withdrawn from escrow by your wallet at any time. Fill times depend on open buyer demand and are estimates, not promises.
• Disputes about a fill lie within the protocol's on-chain rules; Minthouse is not a party to, and cannot adjudicate, a cash-out.

§8 · Consignments

Consignor terms are set out in Conditions of Sale §7.

• Title warranty. Every consignor warrants that they are the sole owner of each consigned lot, that title is good and marketable and free of liens, claims, and encumbrances, and that they have the lawful right to consign it. Breach of this warranty is covered by the indemnity in §14.
• House discretion. We may decline any consignment, and may withdraw a lot at any time before it closes for doubts about authenticity or title, description errors, or legal reasons, without liability beyond returning the lot to the consignor.

§9 · Authenticity guarantee

The heading line of every lot, meaning the set, the card, the grade, and the certification number, is guaranteed for 5 years from the sale date, on the conditions in Conditions of Sale §6.

Rescission, meaning return of the intact slab for a refund of the hammer price plus the auction house fee, is the sole and exclusive remedy for any authenticity claim, in place of every other warranty, right, or remedy relating to authenticity.

§10 · Prohibited conduct

You may not:

• Manipulate bidding. No shill bidding, no bidding on your own consignment or arranging for anyone to bid on it, no collusion to suppress or inflate prices, and no interference with the extension clock or any other mechanic by automated means.
• Scrape. No automated harvesting of lots, bids, results, or bidder data, and no republication of the catalogue at scale without written permission.
• Pay with unlawful funds. No settling invoices with proceeds of crime, and no routing payments to conceal their origin or defeat compliance screening.
• Evade sanctions. You represent that you are not named on, or owned or controlled by anyone named on, any applicable sanctions list, and that you are not located in a comprehensively embargoed jurisdiction. Wallet addresses are screened; payments tied to sanctioned addresses are refused.
• Multiply accounts. One account per person (§3). No registering new accounts, or bidding through someone else’s, to evade a suspension or these terms.
• Attack the platform. No impersonation, no probing or circumventing security, and no reverse engineering of the platform except where the law grants that right.

§11 · Intellectual property

The platform, meaning the Minthouse name and mint mark, the site, catalogue notes, condition descriptions, photography, and slab renders, belongs to Minthouse or its licensors. You get a limited, revocable license to browse, bid, and consign; nothing more transfers, and no content may be reused commercially without written permission.

Card names, set names, team and league marks, and character imagery belong to their respective owners. They appear on the platform solely to identify the physical lots offered for sale, and no affiliation with or endorsement by any rights holder is implied.

Rights holders who believe material on the platform infringes their work may send written notice to the front desk identifying the work, the material and its location, and a way to reach you, with a good-faith statement that the use is unauthorized, attention Copyright Agent, Minthouse Markets, Inc., New York (contact). We remove or disable material as appropriate and close the accounts of repeat infringers.

§12 · Disclaimers

THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, EXCEPT AS EXPRESSLY STATED IN THESE TERMS OR THE CONDITIONS OF SALE.

Descriptions, estimates, and condition notes are the house’s opinion, not statements of fact; lots sell as is, as the Conditions of Sale provide. We do not warrant that the platform will be uninterrupted, timely, secure, or error-free, or that any defect will be corrected. The authenticity guarantee in §9 is the only warranty the house makes about any lot.

§13 · Limitation of liability

TO THE FULLEST EXTENT THE LAW ALLOWS, MINTHOUSE’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE PLATFORM OR THESE TERMS IS CAPPED AT THE GREATER OF (A) THE FEES YOU ACTUALLY PAID TO MINTHOUSE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) $100.

TO THE SAME EXTENT, MINTHOUSE IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST DATA, OR LOSS OF GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY.

Nothing in this section limits liability that cannot be limited by law, including liability for fraud or willful misconduct, Minthouse’s obligation to provide the rescission remedy in §9, or statutory consumer rights that cannot be waived. Where the law permits a limitation only in part, this section applies to the fullest permitted extent.

§14 · Indemnification

You will defend, indemnify, and hold harmless Minthouse Markets, Inc. and its officers, directors, employees, and agents from any claim, loss, or expense (including reasonable attorneys’ fees) arising out of your breach of these terms or the Conditions of Sale, your bids or consignments, including any breach of the title warranty in §8, or your violation of law or of a third party’s rights. We may assume the defense of any matter subject to this indemnity, at our own expense, and you agree to cooperate.

§15 · Dispute resolution

Talk to us first: send written notice of any dispute to the front desk (contact), and both sides will try in good faith to resolve it within 30 days before any filing.

• Arbitration. Any dispute not resolved informally is settled by binding arbitration between you and Minthouse on an individual basis, administered by the American Arbitration Association under its Consumer Arbitration Rules, before a single arbitrator, seated in Wilmington, Delaware, with remote hearings where the rules allow. The Federal Arbitration Act governs this section.
• Class waiver. YOU AND MINTHOUSE EACH WAIVE ANY RIGHT TO A JURY TRIAL AND ANY RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE ACTION. CLAIMS MAY BE BROUGHT ONLY IN AN INDIVIDUAL CAPACITY.
• Small claims. Either party may instead bring a qualifying individual claim in small-claims court.
• Opt-out. You may opt out of arbitration by written notice to the front desk within 30 days of first accepting these terms, stating your name, account email, and intent to opt out. Opting out does not affect any other section.
• Governing law and venue. These terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws rules. For matters not subject to arbitration, the state and federal courts sitting in Wilmington, Delaware have exclusive jurisdiction, and both parties consent to personal jurisdiction there.

§16 · Changes to the terms

We may revise these terms. Revisions are posted here with a new version number and effective date; for material changes we give notice, by email to your account address or by notice on the site, before the new terms take effect. Continued use of the platform after the effective date is acceptance of the revised terms. Changes do not apply retroactively: lots closed before an effective date stay governed by the terms in force when they closed, and changes to §15 do not apply to disputes either party had notice of before the change.

§17 · General

• Severability. If any provision is held unenforceable, it is enforced to the maximum permitted extent and the rest stand.
• Assignment. You may not assign these terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets.
• Entire agreement. These terms and the Conditions of Sale are the entire agreement between you and Minthouse about the platform and supersede all prior understandings.
• No waiver. Not enforcing a provision is not a waiver of it. Waivers are effective only in writing.
• Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, including network and blockchain disruptions, outages, acts of God, and government action, except for payment obligations already accrued.
• Survival. Sections that by their nature should survive, including §§6, 9, and 11–15 and this §17, survive any termination of your account or these terms.
• Notices. Notices to you go to your account email. Notices to us go to the front desk at Minthouse Markets, Inc., New York (contact).

§18 · The demonstration build

These terms are drafted as they would govern a live platform, and they describe exactly how the house would run one. Nothing on this site is an offer to sell any lot or service, an invitation to invest, or an offer of securities or investment services, here or in any other jurisdiction.
