Terms of Service

1. The Service

png.cafe is a set of tools and marketplaces for NFTs on the XRP Ledger (“XRPL”). The Service includes, among other features:

• an NFT marketplace for browsing, listing, buying, and making offers on supported XRPL NFT collections, settled through on-ledger offers that you sign in your own wallet (see Section 4);
• collection pages, galleries, and market data — floors, sales history, volume, trait statistics, top holders, and rarity ranks, aggregated from public on-ledger data and third-party sources;
• public profiles and community features — usernames, profile pictures and banners, X (Twitter) account verification, follows, comments, likes, and notifications;
• a launchpad for creators to configure collections, pin artwork and metadata to IPFS, and schedule launches, subject to review and payment of launch fees;
• the NFT Generator for composing layered collections and exporting metadata compatible with third-party minting workflows;
• holders-only content for supported collections (for example, voxel skin files for Blocky Apes), with ownership verified on-ledger; and
• a browser-based Skin Tester and other utilities that run in your browser.

We may add, change, suspend, or remove features of the Service at any time without notice.

2. Eligibility

You must be at least 18 years old to use the Service. By using the Service, you represent and warrant that you are 18 or older and that you have the legal capacity to agree to these Terms. The Service is not directed to children, and we do not knowingly permit anyone under 18 to use it.

3. Wallets and Third-Party Services

Most features depend on connecting and verifying an XRPL wallet. Wallet sign-in and transaction signing are provided through third-party wallets such as Xaman (XUMM, by XRPL Labs) and WalletConnect-compatible wallets, and on-ledger verification relies on public XRPL nodes. Your use of those wallets, tools, and networks is subject to their own terms and policies, and Calco Labs does not control and is not responsible for them.

You are solely responsible for your wallet, your private keys, your seed phrase, and all activity that occurs through your wallet. We never take custody of your wallet, keys, funds, or NFTs, and we will never ask for your private key or seed phrase. Blockchain transactions are irreversible; we cannot recover, reverse, or restore lost keys, lost assets, or transactions.

4. Marketplace

The marketplace is non-custodial. Listings, offers, and purchases are XRPL NFTokenOffer transactions that you review and sign in your own wallet. Listings created through the Service are directed to our broker account so that sales can settle atomically; when a sale settles, the broker retains a marketplace fee (currently 1% of the sale price) and creator royalties encoded on the NFT are enforced by the XRPL itself. Marketplace fees are earned on settlement and are non-refundable.

• Prices are set by users. We do not set, endorse, or guarantee any price, and we are not a party to any sale between buyers and sellers.
• Supported currencies include XRP and certain issued tokens (for example $FUZZY and $DROP). Issued tokens require trust lines and can be volatile or illiquid; confirm the currency of a listing before you sign. The Service asks for additional confirmation in some flows (for example, typing the token name), but the transaction you sign in your wallet is authoritative — always review it there.
• Market data is informational. Floors, volumes, sales history, statistics, and rarity ranks are compiled from public ledger data and third-party sources (including Bithomp and xrp.cafe) and may be delayed, incomplete, or inaccurate. They are provided for convenience only and are not advice, an appraisal, or a promise of value.
• Listings can go stale. Ownership and offers change on-ledger outside our control; a displayed listing may no longer be fillable. The ledger, not the Service, is the source of truth.

5. Launchpad

The launchpad lets creators configure a collection, pay a launch fee, and submit it for review. Launch fees are paid on-ledger and are non-refundable once the associated services (such as IPFS pinning) have been performed, except where required by law. We may approve, reject, or remove any submission at our sole discretion. Content you pin to IPFS becomes publicly accessible and effectively permanent; do not submit content you do not have the right to publish. You are solely responsible for your collection, its content, and any obligations you make to your own minters or community.

6. Profiles, Community Content, and X Verification

You may create a public profile (username, profile picture, banner) and post content such as comments, links, and reactions. You retain ownership of your content, but you grant Calco Labs a non-exclusive, worldwide, royalty-free license to host, display, and distribute it as part of operating the Service. We may moderate, edit, or remove profiles and content at our discretion, including usernames that impersonate others or content that is unlawful, infringing, hateful, or abusive.

X (Twitter) verification links your profile to an X account you control via X’s OAuth flow. A verified handle is reserved for the wallet that verified it; the verified checkmark displays while your profile’s X handle matches the handle you proved. We may revoke verification or reservations obtained through fraud or impersonation.

7. Acceptable Use

You agree not to:

• circumvent or attempt to circumvent wallet verification, session controls, fees, or any gating in the Service;
• impersonate any wallet, person, or entity, or misrepresent your ownership of any NFT or control of any X account;
• engage in market manipulation, including wash trading or deceptive listings and offers;
• reverse-engineer, decompile, disassemble, scrape at scale, or attempt to derive the source code or algorithms of the Service;
• interfere with, overload, or disrupt the Service or its infrastructure, or use automated means to access it beyond normal use;
• use the Service to infringe intellectual-property rights or to create, distribute, mint, or pin content that is unlawful, infringing, or violates third-party rights; or
• use the Service in violation of any applicable law or regulation.

8. Intellectual Property

The Service, including all source code, design, user interface, text, the NFT generation engine and its algorithms, market data compilations, and all other materials we provide (excluding your own content and your NFTs), is the proprietary property of Calco Labs LLC and is protected by intellectual property laws. All rights are reserved. Except for the limited right to use the Service as expressly permitted here, no license or right is granted to you, and you may not copy, modify, distribute, sublicense, sell, host, deploy, or create derivative works from any part of the Service without our prior written consent. Third-party names, logos, and marks (including collection art and brand marks displayed on marketplace pages) belong to their respective owners.

9. Crypto, NFTs, and No Financial Advice

Nothing on the Service is financial, investment, legal, or tax advice, and nothing constitutes an offer or solicitation to buy or sell any token, NFT, or security. NFTs traded on the Service are digital collectibles; we make no promise or representation of any profit, return, appreciation, value, or future utility, and rarity ranks or statistics do not imply value. Digital assets are volatile and carry substantial risk, including total loss. Blockchain transactions are irreversible and recorded on a public ledger outside our control. You are solely responsible for evaluating and bearing the risks of acquiring, holding, listing, or trading NFTs and tokens and for any tax obligations that arise.

10. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE, ITS MARKET DATA, OR ANY FILES, NETWORKS, OR THIRD-PARTY SERVICES WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, AVAILABLE, OR ACCURATE.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CALCO LABS LLC AND ITS OWNERS, MEMBERS, OFFICERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, WALLET CONTENTS, OR DIGITAL ASSETS, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE SERVICE — INCLUDING ANY MARKETPLACE TRANSACTION, LISTING, OFFER, LAUNCH, OR RELIANCE ON MARKET DATA — WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT WILL OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS EXCEED THE GREATER OF THE FEES YOU PAID US IN THE THREE MONTHS BEFORE THE CLAIM OR ONE HUNDRED U.S. DOLLARS (US $100). Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

12. Indemnification

You agree to indemnify, defend, and hold harmless Calco Labs LLC and its owners, members, officers, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys’ fees, arising out of or in any way connected with your use of the Service, your content, your listings, launches, or transactions, your violation of these Terms, or your violation of any law or the rights of any third party.

13. Termination

We may suspend or terminate your access to the Service at any time, with or without notice, for any reason, including if we believe you have violated these Terms. On-ledger objects you created (such as open offers) are yours to manage and are unaffected by termination of site access. Sections that by their nature should survive termination — including intellectual property, disclaimers, limitation of liability, indemnification, and governing law — will survive.

14. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the “Last updated” date above. Your continued use of the Service after changes take effect constitutes your acceptance of the revised Terms.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the United States and the State of California, without regard to conflict-of-law principles. You agree to the exclusive jurisdiction of the state and federal courts located in California for any dispute arising out of or relating to these Terms or the Service.
