Terms of Service / End-User License Agreement (EULA)

Terms of Service

Last updated: 12 October 2026

1. Acceptance of Terms

By downloading, installing, or using Undersigned ("the App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you must not use the App. These Terms constitute a legally binding agreement between you ("User", "you") and MidMightBit Games, trading as ADappvark ("Developer", "we", "us", "our").

1.1 Capacity to Contract

You must be at least 18 years old and legally capable of entering into a binding agreement in your jurisdiction. By using the App you represent that you are.

1.2 Licence Grant

Subject to your continuous compliance with these Terms, MidMightBit Games (Australia) grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use one copy of Undersigned on a device that you own or lawfully control, solely for your own personal purposes. This licence transfers no ownership to you and may be terminated as described in these Terms.

1.3 Licence Restrictions

You must not (a) copy, modify, adapt, translate or create derivative works of the App; (b) reverse engineer, decompile or disassemble the App except to the extent expressly permitted by applicable law; (c) rent, lease, lend, sell, redistribute or sublicense the App; (d) remove or alter any proprietary notice; (e) use the App to interfere with any blockchain network, wallet, the Solana dApp Store, or any third-party service; or (f) use the App in any way that breaches the Sanctions policy or applicable law.

1.4 Ownership and Reservation of Rights

The App, including its code, design, text and graphics, is owned by the Developer and protected by copyright and other intellectual-property laws. All rights not expressly granted are reserved. See the License and Copyright Notice.

1.5 Open-Source Components

The App incorporates open-source and third-party components under their own licences, including the Solana Mobile Wallet Adapter client library (Apache-2.0), the seeker-verify Genesis Token verification library, and the Manrope typeface (SIL Open Font License 1.1). Those licences govern those components. See the Copyright Notice.

2. Description of Service

Undersigned is a sybil-resistant, on-chain review and trust layer that sits beside the Solana dApp Store. It does not modify, replace, or speak for the store.

• Reviews are transactions you sign. Writing a review builds an unsigned transaction containing an SPL Memo record (a rating from 1–5, one to three fixed tags, and an optional free-text note of at most 140 characters) and a zero-value self-transfer carrying a public reference account, so the record can be found by anyone. The App never signs anything itself; your wallet, through Seed Vault / Mobile Wallet Adapter, does. The only value that ever leaves your wallet is the Solana network fee your own wallet sets — measured at approximately 0.000047 SOL per record on a Seeker device (8 September 2026). The App takes no fee for a review, issues no token, and pays nothing for reviewing.
• Public and permanent. Once your wallet signs and the network confirms it, a review, withdrawal, or reply is public Solana blockchain data, discoverable by anyone through the App's fixed reference address, forever. A withdrawal stops the App counting and displaying a review; it does not and cannot remove the underlying text from the chain. See section 9A.
• Who counts, and how much. A review is stored on-chain regardless of who signs it, but it is counted toward a score only if the signing wallet holds a Solana Mobile Seeker Genesis Token, read on-chain through the seeker-verify library. Every counted wallet carries the same weight, one per attested device. The SKR and SOL that wallet has staked are read and shown beside its reviews for transparency only; they never change a weight or a score, and the App never suggests staking, unstaking, buying, or selling SKR, SOL or any token. Reviews from the Developer's own wallets, and from a reviewer holding Pro given by the reviewed app's publisher, are shown, labelled, and counted in no score. The full rules are in the Review Integrity Policy.
• Reading the store. The App reads the Solana dApp Store's public catalogue, star ratings, and reviews through the store's own public GraphQL feed (dappstore.solanamobile.com). This is read-only: the App never writes to the store, holds no store account, and holds no store credentials. The App is not affiliated with, endorsed by, or sponsored by Solana Mobile. Scores and reviews shown in the App are the signed opinions of individual Seeker owners, not Solana Mobile's or the dApp Store's own ratings.
• On-device facts panel. For apps installed on your device, the App reads installed-package facts (version, signing certificate hash, and requested dangerous permissions) using Android's PackageManager, and compares them with an earlier on-device snapshot to show what changed. This is computed and stored on your device only and is never uploaded. It states facts and deltas only; it is not a claim that any app is safe, unsafe, or a scam.
• Publisher verification. To show a publisher-verified badge on a reply, the App fetches /.well-known/undersigned.txt from the website the dApp Store lists for that app, to confirm the replying wallet is authorised by that publisher.
• Following and alerts. You may follow apps. With your permission (POST_NOTIFICATIONS), the App re-reads the public ledger roughly every six hours and shows a local notification about new signed reviews on followed apps or replies to your own; nothing about you leaves your device for this check.

The App never holds, controls, or has access to your private keys or funds, and never installs, updates, or removes any app on your device; installing or opening an app is a deep link out to the Solana dApp Store, which handles it. "Solana", "Seeker", "Genesis Token" and "dApp Store" are used throughout the App descriptively, to identify the platform the App reads and writes to; they are trademarks of their respective owners and their use does not imply affiliation.

2A. Permissions the App Requests

The App declares the permissions below. Three are requested directly by the App; the remainder are contributed by the Android libraries it uses (Jetpack WorkManager for the scheduled ledger check, and the Solana Mobile Wallet Adapter client for wallet hand-off) and are listed here for completeness because they appear on the App's store listing.

The App requests no location, camera, microphone, contacts, storage, phone or SMS permission of any kind.

2B. The Website and the API

Beside the App, the Developer may run a website and an API that show the same public ledger: a page for each app with its signed reviews, a page for each wallet, a weekly Store watch report, badges that publishers can embed, and pages from which a wallet can sign a review, a reply, a helpful vote or a flag. The App does not depend on them and never sends them anything.

What the website can and cannot do. The website builds a transaction and your own wallet signs it; the website holds no key and cannot sign for you. Nothing on the website can change or delete a record on-chain. The Developer may stop the website and API showing the text of a record (for example where it is unlawful or exposes private information); the record stays listed, marked as such, and stays on-chain. See section 9A and the website's "Report content" page.

The API is offered as is, with rate limits, and may change or stop. Store ratings and catalogue data shown there belong to the Solana dApp Store.

3. Permanence and Your Responsibility

Publishing a review, revocation, or reply is final in one specific sense: the text itself cannot be deleted from the Solana blockchain by you, by us, or by anyone, once the network confirms it. Before your wallet opens, the App shows you exactly what will be written and, for free text, a second consent screen with the permanence warning in full. You are responsible for reading it. In particular:

• Withdrawing a review (a revocation record) stops the App counting and displaying it. The chain record itself is unaffected and remains readable by any other application or block explorer.
• Whether a review counts depends on facts read from the chain at the time of reading (Genesis Token ownership) and can change without any action by you. Staked SKR and SOL are shown beside a review for transparency and never change its weight.

4. No Warranty

The App is provided "AS IS" and "AS AVAILABLE" without warranty of any kind, express or implied, including any warranty of merchantability, fitness for a particular purpose or non-infringement. We do not warrant the accuracy or completeness of the dApp Store's public catalogue, the on-chain review ledger, the installed-app facts panel, staked-SKR weighting, or that any transaction will be accepted by the network, or that RPC providers, the dApp Store's feed, or wallets will be available or error-free.

Nothing in these Terms excludes, restricts or modifies any consumer guarantee, right or remedy you may have under the Australian Consumer Law or other applicable consumer protection laws that cannot lawfully be excluded.

5. Limitation of Liability

To the maximum extent permitted by law, the Developer is not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of reputation, profits, data or goodwill, arising from or related to your use of the App, including from:

• Content you or any other user chose to publish to the public ledger, or reliance on any score, tag, review, or on-device fact shown by the App
• Network congestion, failed or partially confirmed transactions, or RPC provider or dApp Store feed outages
• Wallet software behaviour, including changes a wallet makes to a transaction before submitting it
• Changes to the Solana dApp Store's public feed, the Genesis Token or staked-SKR programs, or the Solana runtime
• The review analytics in the App and on the website: aggregate statistics (counts, means and shares by category, dApp and period) of the dApp Store's public reviews and of the signed reviews on the ledger. Store data belongs to the Solana dApp Store; no store review text or wallet address is republished by us. These figures are information, never a verdict or a recommendation.

Our total liability for any claim relating to the App is limited to AUD 20 or, if you hold a Pro licence, the amount you paid for the current term, whichever is greater, except where a consumer guarantee that cannot lawfully be excluded applies.

6. Data Accuracy

Scores, catalogue metadata, Genesis Token status, staked-SKR figures, and installed-app facts are read live from public Solana RPC providers, the dApp Store's public feed, and your device's PackageManager. They can be stale, rate-limited, cached, or wrong. Because ranking is deterministic from whatever the chain shows at read time, two devices reading at different moments, or with different local caches, may show different scores for the same app until both catch up.

7. User Responsibilities

• Keep your wallet, seed phrase and device secure. We never ask for them.
• Review what the App will write to the chain, and the permanence warning on free text, before approving anything in your wallet.
• Keep a small SOL balance in your wallet to cover the network fee for each review.
• Comply with the laws of your jurisdiction, and with section 9A (User-Generated Content), for anything you publish.

8. Sign In With Solana (SIWS)

Undersigned uses the Solana Mobile Wallet Adapter for Sign In With Solana. By using this feature, you acknowledge that:

• Signing in proves control of the wallet and records your acceptance of these Terms; it moves no funds
• The App reads that wallet's Genesis Token status, staked SKR, and public reviews through public Solana RPC providers and the dApp Store's public feed; those requests carry the wallet's public address
• The App also checks, on-device, which country your SIM, mobile network, or locale indicates, and blocks access from the jurisdictions listed on the Sanctions page before it lets you continue
• Before the App accepts a wallet, and again before any review transaction, the wallet's public address is screened against the OFAC SDN list on the device and, where reachable, TRM Labs' public sanctions screening service. A listed address cannot use the App
• Every transaction the App prepares is presented to your wallet for approval; the App cannot sign or submit anything on its own
• The App stores your wallet's public address on your device as part of your consent record and to skip sign-in next time
• You are responsible for the security of your Solana wallet and private keys

8A. Fees: free to read and sign; Pro is an optional licence

Reading the ledger, signing reviews, replies, flags, clears and disputes, claiming an app and the device-facts panel are free and always will be. There is no subscription, no token issued by the App, and nothing paid for reviewing, following or replying. The only value that leaves your wallet for any of these is the Solana network fee, which your own wallet sets and which goes to the Solana network, never to the Developer.

Pro is an optional software licence for tools around the signing: importing your store reviews, the publisher desk, exporting the ledger as CSV or JSON, and hourly alerts for the apps you follow. Copying a signed review to the dApp Store listing is free. It is priced in SOL or in SKR, at your choice; the exact amount in each is shown in the App before you sign, and the SOL and SKR legs are re-pegged only between releases, never after you have paid. A term lasts twelve months from the moment the payment confirms. Nothing renews by itself and nothing can bill you: renewing is another transaction you choose to sign, and a renewal signed before a term ends starts when that term ends.

The payment is a transfer from your wallet to the Developer's treasury address DD4aPDhf396NhNDxa4PBVf1u3uzCUP2QYm2dFMmJWq2Q (for SKR, to that address's associated token account), carrying a public reference and the memo UNS. That payment is the licence: the App reads the amount you paid and the twelve-month term follows from it. It is public and permanent like every other record on the ledger — anyone reading the ledger can see that the paying wallet holds Pro and until when. The licence is tied to the wallet, not to the device; any phone signed in with that wallet has it, and the App reads it from the chain with no account, no server and nothing stored about you.

Listing a treasury on the payments board costs a one-time fee per app and treasury, paid in SOL or SKR in the same transaction that signs the listing; the exact amount in each is shown before you sign, with a lower SKR amount for wallets holding a Seeker Genesis Token. Changing the payment code or listing again later costs only the network fee. A listing shows payments your treasury has received on-chain; it is not advertising and buys no ranking.

An API pass is an optional licence to call the paid parts of the API: a stated number of requests over a stated number of days, bought with one SOL or SKR transfer to the same treasury address. The amounts and what they buy are shown by the API before you pay. A pass is redeemed by the wallet that paid, or by whoever holds the checkout secret issued for that payment; keep it private. Paying again adds requests and time. A pass does not renew by itself. A payment below the pass price, from the minimum top-up the API states, buys pay-per-call credits instead: calls at the per-call rate the API states, valid for a year, kept apart from any pass. The same terms apply to credits as to a pass.

Pro buys tools, a Pro member mark and its own labelled score line; it never changes the signed score. The signed score counts every counted review once, weighted by the attested device, one per attested device (staked SKR and SOL are shown beside each review for transparency and never weighed) and what the review carries (install time, usage, a written note); no payment to the Developer enters it, and paying the Developer never makes a review count for more. Beside it, the App shows a separately labelled "Pro members" score for reviews written while the author held Pro, with its own count, and lists reviews under the headings Organic reviews, Pro members, Promoted reviews · paid, Related to Undersigned or the publisher, and Not counted. A Pro member may pay to promote their own review, and in paying confirms they are not paid by, employed by or acting for the app's publisher or a competitor; promotion bought for anyone else's benefit is prohibited and is withdrawn when found: it is then listed in a separate, shaded "Promoted reviews · paid" section after the organic reviews, marked "Promoted · paid" and counted in a separate Promoted score; it is never shown first and its weight and the signed score are unchanged. Promotion is not available to verified publishers, the Developer's own wallets, holders of a Pro seat given by the app's publisher, or on apps the Developer publishes. A Pro seat given by an app's publisher makes its holder's review of that publisher's apps count in no score. Payment never changes how anyone's review is flagged, cleared, disputed or hidden. See the Review Integrity Policy.

Refunds and your statutory rights. Pro and a promotion are digital content and services supplied immediately. Before you pay, the payment screen asks you to request immediate supply and to acknowledge that you lose any fourteen-day withdrawal right once the payment is confirmed on-chain (Directive 2011/83/EU art. 16(m); UK Consumer Contracts Regulations 2013 reg. 37); the confirmation, with the transaction signature as your receipt, is shown when the payment confirms. You cannot pay without giving that consent. Your rights under the Australian Consumer Law and under Directive (EU) 2019/770 (see "Conformity of digital content" below) are unaffected: if a Pro tool does not work as described and we cannot bring it into conformity within a reasonable time, you may ask for a proportionate refund of the current term, paid to the wallet that paid, in the token it paid with. Solana network fees go to the network and are not refundable by us. A payment that never confirmed on-chain was never charged. To claim, email the address in section 13 with the licence transaction signature.

9. Intellectual Property

"Undersigned", the App's icon and artwork are trademarks or trade dress of the Developer. "Solana", "Seeker", "Genesis Token" and "dApp Store" are trademarks of Solana Labs, Solana Mobile Inc. or the Solana Foundation, used descriptively; the App is not affiliated with, endorsed by or sponsored by Solana Foundation, Solana Labs or Solana Mobile.

9A. User-Generated Content and the Public Ledger

This section governs anything you choose to publish through the App: a rating, tags, free-text note, revocation, or publisher reply.

• You own your words, and you are responsible for them. You alone are responsible for the content of any review, note, or reply you sign, including its accuracy, and for any claim of defamation, intellectual-property infringement, or unlawful disclosure of another person's personal data that arises from it.
• Free text is optional and capped. A note is optional, at most 140 characters (and at most 280 UTF-8 bytes), and requires a second, explicit consent screen — separate from these Terms — that states, before your wallet is asked to sign: that the text will be written to the Solana blockchain; that it is public and permanent; that it cannot be deleted by you, by us, or by anyone; and that you can withdraw it from the App's ranking, but the text itself stays on-chain forever.
• Prohibited content. You must not publish content that is unlawful, defamatory, harassing, or that infringes another person's intellectual property or discloses their personal data without their consent, or that impersonates a publisher or another reviewer.
• Reporting and hiding. Every review carries an in-app report control that emails a report to us and hides the review on your device. Withdrawing a review you signed stops the App counting and displaying it for you and for other readers of the App; it does not remove the chain record.
• Publisher replies. A person who controls the wallet that receives an app's payments, verified as described in section 2, may sign a reply to a review on that app. Replies are shown alongside the review but are not counted toward any score.
• Right to erasure and the public ledger. The Australian Privacy Act, the GDPR, and similar laws give you rights over personal data, including a right to erasure. Because a review's text and your wallet's public address (pseudonymous personal data you choose to publish) are written by your own act to a public, permanent, decentralised ledger that the Developer does not host, control, or have the power to alter, we cannot delete that record on your behalf. What we can and do honour, within the App, is your ability to withdraw a review from being counted and displayed, and to hide any review from your own device.
• You must be 18 or older to sign in or publish any content through the App.

10. Restricted Regions

Undersigned is not available for use in 17 sanctioned or restricted jurisdictions: Belarus (BY), Central African Republic (CF), Cuba (CU), Democratic Republic of the Congo (CD), Iran (IR), Libya (LY), Myanmar (MM), Nicaragua (NI), North Korea (KP), Russia (RU), Somalia (SO), South Sudan (SS), Sudan (SD), Syria (SY), Venezuela (VE), Yemen (YE) and Zimbabwe (ZW). You represent and warrant that you are not located in, and are not a resident or national of, any of them. See our Sanctions & Restricted Regions page for details.

11. Termination

We may terminate or suspend your licence if you breach these Terms. You may stop using the App at any time by uninstalling it. Sections 3 to 6, 8A, 9, 9A, 12 and 16 survive termination. Termination does not, and cannot, remove any content already confirmed on-chain.

12. Indemnification

You agree to indemnify and hold harmless the Developer from any claim, loss or expense (including reasonable legal fees) arising from your breach of these Terms, your use of the App, or any content you published or transaction you approved in your wallet.

13. Modifications to Terms

We may update these Terms. The current version is published at this page and its version number is shown in the App; the App asks you to accept a new version before continuing. Continued use after a change constitutes acceptance.

14. Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force.

15. Entire Agreement

These Terms, together with the Privacy Policy, Copyright Notice, License, Disclaimer, and Sanctions policy, constitute the entire agreement between you and the Developer regarding the use of Undersigned and supersede all prior agreements and understandings.

16. Governing Law

These Terms are governed by the laws of Victoria, Australia. Subject to the European Union and EEA section below and to any mandatory consumer-protection law of your place of residence, you submit to the non-exclusive jurisdiction of the courts of Victoria, Australia.
