Terms of Service

01Agreement to these Terms

These Terms of Service (“Terms”) govern your use of the HYPURR.STKR mobile application, the website at hypurrstkr.xyz, and any related services (together, the “Service”). By creating an account, signing the licence message at checkout, or placing an order, you agree to these Terms. If you do not agree, do not use the Service.

You may use the Service only if you are at least 18 years old, have reached the age of majority where you live, and can form a binding contract.

These Terms work together with our Privacy Policy and with the licence message you sign at checkout (section 5). Where that message and these Terms conflict, these Terms control, except on questions of copyright licensing, where the signed message controls.

02Definitions

• Hypurr NFT — an NFT from the Hyperliquid ecosystem collection we use to determine eligibility. We did not issue it and we do not control it.
• Series (or Drop) — a time-limited release of physical stickers, identified by a code such as 2026-09.
• Snapshot — a record of which wallet held each Hypurr NFT at a specific block, taken before a Series is released. It is used for Vault eligibility and event issuance (section 4).
• Bound Wallet — a wallet you have linked to your account by signing a message, so that its holdings count toward your eligibility. We never take custody of a Bound Wallet.
• Embedded Wallet — the wallet created for your account by our login provider when you sign in, used to sign messages and pay for orders.
• Sticker — the physical product we produce and ship or hand over.
• Vault NFT — an on-chain token minted in connection with an order (section 8).
• Chip — the NFC authenticity chip embedded in certain Stickers (section 12).

03Accounts and wallets

You sign in through a third-party authentication provider using a social login. When you first sign in, an Embedded Wallet is created for your account. You are responsible for keeping access to your login method secure. Anyone who can access your login can access your account.

You may bind additional wallets you control by signing a message with them. Binding proves control of an address; it does not give us the ability to move assets from that address. One account per person. You may not sell, rent, or share your account.

Deleting your account

You may delete your account at any time from within the app, or by emailing support@hypurrstkr.xyz. Deletion removes your profile and personal data as described in our Privacy Policy, subject to records we are required by law to retain. Deletion cannot remove data already written to a public blockchain — see section 8 and the Privacy Policy.

04Eligibility and snapshots

Who can buy depends on the Sticker type. Holdings count when they are in your Embedded Wallet or a Bound Wallet. Our docs explain the rules in full under Purchasing & eligibility.

• Vault — you must have held that Hypurr NFT at the Series Snapshot and still hold it when you buy. Selling or transferring it after the Snapshot ends your Vault eligibility for that Series, and acquiring it after the Snapshot does not create eligibility for that Series.
• Wild — open to everyone, within the purchase limits. Hypurr holders can also buy the Wild made for their own Hypurr number; this depends on holding it when you buy, not on the Snapshot.
• Special and event Series — the sticker types, conditions and limits are set for each event and shown in the Series information. For some events we issue the Stickers to wallets in the Snapshot instead of selling them.

The sales period applies to everyone. Once it ends, the Series can no longer be bought, and being in a Snapshot does not extend it.

We read holdings from public blockchain data through third-party providers, and a reading can be delayed or wrong. If you believe we misread your holdings, contact us and we will re-check; our good-faith determination is final. Eligibility does not guarantee availability: Series are limited (section 6) and may sell out before you order.

05Licence

Every purchase requires the licence below. At checkout, the app shows you the licence message and you agree by signing it with your Embedded Wallet; where possible, the same signature also approves your payment. We record the message, its version and your signature with each order. Which licence applies depends on your Bound Wallets:

• If a Bound Wallet holds Hypurr NFTs, you allow SJ Partners Co., Ltd. (.STKR) to make and sell sticker derivative works of the Hypurr NFTs held by your Bound Wallets. You keep your NFTs and their artwork; the licence does not transfer ownership of either.
• Otherwise, for example when you buy Wild without a Hypurr NFT, you acknowledge that your purchase includes a 10% royalty that .STKR pays to Hypurr holders.

06Orders and limited editions

Stickers are produced in limited quantities per Series. We publish the edition size and the purchase limits for each Series. Quantities are allocated in the order valid orders are received and confirmed.

Placing an order is an offer to buy. A contract is formed only when we confirm your order in the app or by email. We may decline or cancel an order, before or after payment, if:

• the Series has sold out or the item is no longer available;
• the price or product description was wrong because of an obvious error;
• we cannot verify your eligibility;
• we cannot ship to your address (section 9);
• we reasonably suspect fraud, abuse, or a breach of section 14 or 15.

If we cancel a paid order for any of these reasons, we will refund you as described in section 11.

07Price and payment

Prices are shown in the app before you confirm, and are quoted in USDC on the payment chain we specify at checkout. Shipping is priced separately by destination zone and shown before you confirm. When you pay in USDC through the app, we pay the network (gas) fee.

You are responsible for any taxes arising from your purchase other than taxes on our income. Cryptocurrency values fluctuate; the amount you pay is the amount quoted at checkout in the quoted asset, regardless of what that asset is worth later.

We do not accept payment cards or in-app purchase for Stickers. Physical goods consumed outside the app are paid for outside Apple’s in-app purchase system.

08The Vault NFT

In connection with an order we may mint a Vault NFT to your wallet. The Vault NFT is a record that pairs your physical Sticker with an on-chain entry. It is a collectible and a receipt. It is not a security, not a share, not a claim on our revenue or assets, and not a promise of any future benefit, airdrop, or value.

Transferring or selling a Vault NFT does not transfer any right against us, including any warranty, replacement right, or right to future Series. Those rights stay with the original purchaser.

09Shipping worldwide

We ship worldwide, except to destinations we cannot lawfully or practically serve (section 15). Production and dispatch times are estimates published per Series, not guarantees. Carrier delays, customs holds, and force majeure are outside our control.

Address accuracy

You are responsible for the accuracy of the recipient name, address, and contact details you provide. If a shipment is returned or lost because the address was wrong or incomplete, or because the recipient did not collect it, we may charge you the cost of reshipment. Address changes are only possible before dispatch.

Customs, duties and import taxes

Risk and title

Risk of loss passes to you on delivery to you or to a person you designate. Title passes when we receive payment in full.

10Pickup at events

Some Series may be offered for pickup at an announced event instead of shipping. If you select pickup:

• you must collect within the window we announce for that event;
• we may require you to prove control of the ordering wallet at pickup;
• once pickup is selected and locked for an order, switching to shipping may not be possible; the app tells you when that lock applies;

Events may be rescheduled or cancelled. If an event is cancelled and we cannot offer a reasonable alternative, we will refund the order.

11Cancellation and refunds

Before production begins, you may request cancellation through support@hypurrstkr.xyz. After review, we may return the assets you paid, in the same form.

Orders are final once production starts. Each Series is made in a limited run, so once production of your order has started you cannot cancel it or return it because you changed your mind.

If an item arrives defective, is lost in transit, or was shipped in error, contact support@hypurrstkr.xyz with your order details. We review each case individually and tell you what we can offer, such as a replacement or a refund.

How refunds are paid

Any refund we agree to, including for an order we cancel, is paid in the same asset you paid with, to the wallet the payment came from, for the amount you paid in that asset. We do not compensate for changes in the market value of that asset between payment and refund, and we do not refund blockchain network fees, which we never received.

A Vault NFT minted for a refunded order may be marked void. It stays on-chain but carries no rights.

12Authenticity chip

Some Stickers contain an NFC chip that generates a one-time code each time it is read. When you tap it with your phone, our website checks that code and confirms the Sticker came from us. Verification tells you that a chip we programmed responded correctly. It does not certify condition, provenance after it leaves us, or market value.

Each chip is issued once, for one Sticker, as part of a limited edition. Chips are not reused across Series. Attempting to clone, extract keys from, re-program, or transplant a chip is a breach of these Terms and may be an offence.

Chips can fail. Physical damage, exposure, or ordinary wear may stop a chip responding. A non-responding chip does not by itself mean a Sticker is counterfeit, and a chip that stops working after delivery does not by itself entitle you to a replacement. If a Sticker arrives with a chip that does not respond, contact us under section 11.

13Intellectual property

The Service, the HYPURR.STKR name and logo, the site and app design, and the Sticker designs we create are owned by us or our licensors. Buying a Sticker gives you ownership of that physical object. It does not give you any licence to reproduce, manufacture, or commercially exploit the designs on it.

“Hyperliquid”, “Hypurr”, and related names, logos, and NFT artwork belong to their respective owners. We are an independent project. We are not operated, endorsed, sponsored, or certified by Hyperliquid or by the issuers of any NFT collection, unless we state otherwise in writing for a specific Series.

If you believe something on the Service infringes your rights, email support@hypurrstkr.xyz with enough detail to identify the work and the material complained of, and we will investigate.

14Acceptable use

You must not:

• reproduce, counterfeit, or mass-manufacture Stickers, or use images of them to suggest a fake is genuine;
• use bots, scripts, or multiple accounts to obtain more than your allocation in a Series;
• scrape, probe, overload, or attempt to gain unauthorised access to the Service or its infrastructure;
• provide false identity, address, or wallet-control information, or bind a wallet you do not control;
• use the Service to launder money, evade sanctions, or fund unlawful activity;
• interfere with the Chip verification system or forge verification results.

We may cancel orders, withhold shipments, and suspend or close accounts that breach this section.

15Sanctions and restricted regions

You represent that you are not located in, ordinarily resident in, or ordering on behalf of anyone in a country or region subject to comprehensive trade sanctions, and that you are not listed on any applicable sanctions or restricted-party list, and that no wallet you use is.

We may screen wallet addresses and shipping destinations against sanctions and export-control lists and may refuse or cancel any order on that basis. We may also refuse destinations where we cannot ship lawfully or reliably.

16No investment advice

Nothing on the Service is financial, investment, tax, or legal advice. Stickers are collectibles and Vault NFTs are records — neither is offered as an investment, and we make no representation that either will hold or increase in value. We do not operate a marketplace, exchange, or secondary market, and we are not a party to any resale.

Balances shown in the app are read from public blockchain data for your convenience. They may be delayed or wrong, and they are not a statement of account from us.

17Third-party services

The Service depends on third parties, including our authentication and wallet provider, our hosting and database provider, blockchain RPC providers, block explorers, name-resolution services, and shipping carriers. Their outages, errors, policy changes, or termination can degrade or interrupt the Service. We choose these providers with reasonable care but we do not control them and are not responsible for their acts or omissions, except where the law does not allow us to exclude that responsibility. Which providers we use and what data they receive is set out in our Privacy Policy.

18Changes, suspension, termination

We may change, suspend, or discontinue any part of the Service, including any Series, at any time. We will give reasonable notice where a change materially affects orders you have already placed. If we cancel a Series you have paid for, we refund you under section 11.

You may stop using the Service and delete your account at any time. We may suspend or close your account for breach of these Terms, for suspected fraud, or where required by law. Sections 8, 11, 13, 16, 19, 20, and 21 survive termination.

19Disclaimers

To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, that eligibility readings or Chip verifications will be correct, or that the blockchain networks we rely on will operate correctly, remain available, or preserve your assets.

We are not responsible for blockchain risk, such as network failure, congestion, forks, reorganisations, protocol changes, smart contract vulnerabilities or loss of keys, which can delay transactions or cause the total loss of digital assets, except where a loss results from our own failure to take reasonable care.

20Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, data, goodwill or the market value of any digital asset, arising out of or in connection with the Service or these Terms, even if we were told such a loss was possible.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, such as liability for fraud, or for death or personal injury caused by negligence.

21Governing law and disputes

These Terms are governed by the laws of the Republic of Korea, without regard to conflict-of-law rules.

If you are a consumer, this choice of law does not deprive you of the protection of mandatory consumer-protection rules of the country where you habitually reside, and you may bring proceedings in the courts of your place of residence.

Please contact us first at support@hypurrstkr.xyz; most issues are resolved without formal proceedings.

22Changes to these Terms

We may update these Terms. We will post the new version here with a new effective date and, for changes that disadvantage you or materially change your rights, give at least 30 days’ notice in the app or by email before they take effect. If you do not accept a change, stop using the Service and delete your account before the effective date. Orders already confirmed stay under the version in force when you placed them.
