2. Understanding this EULA

2.1 This Polkadot App End User Licence Agreement (this “EULA”) describes how you may download, access, use and interact with the App, including the products and services made available through the App. Clauses 1-21 set out the general terms that apply to your access, use and interaction with the App. By accessing the App, this EULA will apply to you, and you agree to this EULA. You should therefore read this EULA carefully in full before using the App.

2.2 Certain additional terms and/or policies may be applicable to the individual services and functionalities that are available from us or from third parties through the App (“Additional Terms”), and you must ensure that you read and agree to such Additional Terms prior to using the applicable service or functionality. In the event of any conflict between a provision of this EULA and a provision of any Additional Terms, the applicable provision of the Additional Terms shall prevail solely in relation to the applicable service or functionality to which such Additional Terms relate.

2.3 Depending on your jurisdiction of residence, (i) this EULA may be supplemented and amended by the terms as set out in the relevant Appendix (see the relevant Appendix for your jurisdiction at the end of this EULA); and (ii) some specific functions of the App will not be available for you. Please read the terms set out in the Appendix applicable to your jurisdiction of residence carefully before using the App.

2.4 When certain words and phrases are used in this EULA, they have specific meanings (these are known as “defined terms”). You can identify these defined terms because they start with capital letters (even if they are not at the start of a sentence). Where a defined term is used, it has the meaning given to it in the section of this EULA where it was defined (you can find these meanings by looking at the sentence where the defined term is included in bold and speech marks).

2.5 References in this EULA to a “paragraph” of a Schedule are to the paragraphs contained in that Schedule. Each Schedule forms part of this EULA and has effect as if set out in full in the main body of the EULA.

2.6 If you are acting for purposes that are wholly or mainly outside your trade, business, craft or profession, you are acting as a “Consumer”. If you are acting for purposes relating to your trade, business, craft or profession, then you are acting in the course of a business (a “Business User”).

2.7 In this EULA, when we refer to “we”, “us” or “our” (or similar), we mean the Company; and when we refer to “you” or “your” we mean:

2.7.1 if you are a Consumer: you, the person accessing or using the App; or

2.7.2 if you are a Business User: the business on whose behalf you are acting.

2.8 If you are a Business User when you access and use the App, you represent and warrant that:

2.8.1 you have full legal authority to bind the business you represent; and

2.8.2 you agree to this EULA on behalf of the business that you represent.

3. The App

3.1 The App is made available free of charge. If the App incorporates any additional content, services or features which are available for a cost, the applicable prices will be set out in the App and will be tax inclusive.

3.2 This App requires a phone or other compatible smart device running either iOS or Android operating systems (the device you use will be referred to as the “Device”) with Internet access. You may not be able to use the App if the operating system on your Device is not up-to-date. We reserve the right to set or modify the minimum version of the App and define the minimum supported version of the iOS and Android operating system at any time.

3.3 This App usesiCloud (for iOS Devices) or Google Drive and associated password manager services (for Android Devices) for backup of your credentials. You will be able to use the App without providing ongoing access to these services, however all backup and recovery needs to be handled by you.

3.4 This App backs up your self-custodial digital wallet functionality included in the App (the “Wallet”) to iCloud or Google Drive - this backup should never be deleted. If this backup is deleted, altered or otherwise tampered with, you will permanently lose access to your Wallet and any cryptoassets that it contains.

3.5 You are responsible for making all arrangements necessary for you to have access to the App to use the services made available thereon. You are also responsible for ensuring that all persons who access and use the App through your Internet connection are aware of this EULA and that they comply.

3.6 The App and the content on it are provided for general information purposes only. They are not intended to amount to advice on which you should rely.

3.7 You will be assumed to have obtained permission from the owners of any Devices that are controlled, but not owned, by you to download a copy of the App onto the Devices. You and they may be charged by your and their service providers for internet access on the Devices. You accept responsibility in accordance with this EULA for your use of the App on or in relation to any Device, whether or not it is owned by you.

3.8 To use the App, you must also review and agree to the additional app terms set out in Schedule 2 to this EULA and any other terms and conditions imposed by the app store from which you have downloaded the App.

4. Your Username

4.1 Registration of a unique Username (and an associated App account (“Account”)) is required to access the core features of the App. You must be at least 18 years of age (or, if older, the age of majority in your jurisdiction of habitual residence) in order to acquire a Username and register an Account.

4.2 Each Username is generated by reference to the user’s “Private Key” (being the cryptographic keys generated by the App and stored locally on the Device that control Wallet access and facilitate all cryptographic operations with blockchain technology through the App) and registered on the Polkadot Network. The Username serves as your on-chain identifier and links to the associated Wallet Address (defined below).

4.3 Once registered, your Username is recorded immutably on the Polkadot Network together with your “Wallet Address” (being the on-chain address generated from the user’s Private Key for use with the Wallet) and may be visible to other network participants. The Company cannot alter, delete or reassign any Username record on-chain.

4.4 Private Keys are stored solely on-Device and never transmitted to the Company or any third party. The Company cannot recover a Private Key, Username or Wallet, and is not liable for any loss resulting from device compromise or credential loss.

4.5 By registering a Username and opening an Account, you represent and warrant that all information provided in connection with your registration is complete and accurate, and that you are the individual or entity associated with the Wallet Address and Private Key used to generate the Username and register your Account. You must not impersonate any other person or misrepresent your identity in any way.

4.6 We reserve the right to disable or remove any Username at any time, if in our reasonable opinion you have failed to comply with this EULA (although this will not prevent you from accessing any funds in your Wallet).

4.7 You are responsible for any unauthorised use of your Username and/or Account (including as a result of fraud, scams, phishing, or other criminal activities committed against you by third parties).

5. Services

The App provides certain services and functionalities, as further detailed in the App, and some of which may be subject to Additional Terms (for which see clause 2.2). Please note that you may only use the App and its services and functionality to the extent that such use is lawful for you and only in jurisdictions where the App is lawfully made available and its use is permitted. We reserve the right, acting reasonably in our sole discretion, to determine your eligibility to use the App. We may require you to provide additional information or documentation to verify or confirm your eligibility, including on a periodic or ongoing basis.

Schedule 1: Specific Product and Service Terms

The following specific terms apply to your use of individual products or services that may be made available to you by us or by a Third Party Provider through the App. These terms supplement the other terms of the EULA.

Definitions

For the purposes of this Schedule 1, the following terms have the meanings set out below. Capitalised terms not defined in this Schedule 1 have the meanings given elsewhere in the EULA.

“Chat Functionality” means the peer-to-peer, end-to-end encrypted messaging feature of the App.

“Digital Assets” means cryptoassets supported by the App, including Supported Tokens and Stablecoin.

“Individuality Functionality” means the functionality in the App which. via Proof of Video Interaction (and/or any other “Proof of” verification system introduced by the Company from time to time), seeks to verify that participating users are human.

“Peer” means a user whose individuality verification has been successfully recorded on the Polkadot Network via the Individuality Functionality.

“Peer Rewards” means any rewards distributed to Peers from time-to-time, as determined by autonomous logic on the Polkadot Network.

“Private Keys” means the cryptographic keys generated by the App and stored locally on the Device that control Wallet access and facilitate all cryptographic operations with blockchain technology through the App.

“Proof of Video Interaction” means the decentralised identity mechanism described in paragraph 3.3.

“Stablecoin” means the stablecoin issued and exchanged within the Polkadot ecosystem as described in this Schedule (being dotUSD at the date that this EULA was published but which may be updated as set out in the App from time to time).

“Supported Tokens” means any tokens designated by the Company as supported within the App from time to time.

“Transaction Data” means immutable on-chain data generated by the Wallet for each transaction, including (for example) amount, token type, timestamp and Wallet Address.

“Wallet Credentials” means any credentials that allow access to or control of the Wallet, including Private Keys, any secret recovery phrase, passwords or PINs.

1. Wallet Functionality

1.1. The Wallet (labelled “Pocket” in the App) enables you to receive, hold, convert, and transfer Supported Tokens within the Polkadot ecosystem and to otherwise manage those Digital Assets using features made available in the App. You can send funds to other users using private payment functionality that makes use of the “Coinage” system (an internal cryptographic mechanism seeking to ensure that transactions remain private):

1.1.1. When you purchase or onboard funds into the Wallet, you will automatically be “onboarded” to the Coinage system any your Stablecoin will be deposited into the Coinage system and in exchange you will be issued with private fungible coins of the same value (“Coins”).

1.1.2. When sending a Coin to another user, the keys to the relevant Coin accounts are privately sent to your intended recipient.. The recipient can claim the Coins into a new account created for each such transaction.

1.1.3. Coinage preserves your privacy by using fungible single-use Coin accounts. Within the Polkadot ecosystem Coins will, from time to time, automatically be mixed with other Coins and taken back out in fresh form to improve fungibility (“Recycling”).

1.1.4. You may offboard funds from the Coinage system by redeeming your Coins for the corresponding amount of Stablecoins. The Coins will be burned, and the equivalent Stablecoins will be released to your Wallet, allowing you to transfer or use them outside the private Coinage system, including through public smart contracts.

1.2. At launch, the Wallet supports Supported Tokens and the Stablecoin. It may interface with other App features, including Chat Functionality and Individuality Functionality, as further detailed within the App itself.

1.3. In order to provide Wallet functionality, Supported Tokens are automatically converted into Stablecoins through cross-chain operations within the Polkadot ecosystem.

1.4. Transaction Data and Liability

Please note that:

1.4.1. Transaction Data is permanently recorded on the blockchain and may be viewed by other network participants. We do not control how or when transactions are processed by the network and are not responsible for any delays, duplicates, failures or other errors that may occur due to network conditions, high activity or technical issues. We are not liable to you if you transfer a Digital Asset to an incorrect or unintended wallet address or otherwise make an unauthorised or mistaken transaction.

1.4.2. The Company does not have control over your Private Key or your funds. At no point do funds pass through a custody solution under the Company’s control.

1.5. Security and Recovery

You must ensure the security of your Device, your Wallet Credentials and your backup accounts. The App uses a recovery mechanism through iCloud and Google Drive, and your encrypted Private Key generated by the App is stored in your iCloud or Google Drive. Altering, disabling or deleting those backups may render your Wallet unrecoverable and result in permanent loss of your Digital Assets. The Company cannot reset, recover or otherwise restore Wallet Credentials or Digital Assets.

While the cloud backup is secure, we suggest manually backing up your Private Key, using the process set out in the settings of the App.

1.6. Regulatory and Disclaimer

1.6.1. The App is a software interface for decentralised networks. It is not a financial product, and the Company does not provide investment, custody or payment services.

1.6.2. The Company is not authorised or regulated by any financial or securities authority. Use of the Wallet or any Digital Asset functionality does not constitute use of a regulated exchange, payment service or custody service in any jurisdiction.

1.6.3. The App is provided on an “as-is” and “as-available” basis. The Company makes no representation or warranty regarding uninterrupted or error-free operation and disclaims all responsibility and liability for any unauthorised access, loss of Digital Assets, transaction failure, transmission error or asset-value fluctuation, or for any losses or damages arising out of or in connection with your use of the Wallet.

1.6.4. The Company may modify, restrict or suspend the Wallet Functionality at any time to comply with applicable laws or governance requirements or to ensure network stability.

2. Chat Functionality

2.1. The App includes Chat Functionality, which as well as providing the ability to engage in peer-to-peer communications, interacts with other App services by (for example) displaying notifications in the chat interface regarding Wallet transactions and the receipt of Peer Rewards.

2.2. To send or receive messages, or participate in voice or video chats, group chats and/or public broadcast chats, a user must have registered a Username.

2.3. All encrypted chat contents is stored by node operators of the Polkadot Network for up to 48 hours or (if earlier) until they are downloaded by the recipient using the Private Key associated with their Wallet Address. After download or expiry of the 48 hour period, whichever is earlier, they are automatically deleted.

2.4. Once downloaded, messages are decrypted locally and displayed within the recipient’s App. If the App is not open when a message is sent, a push notification may be delivered to the recipient’s Device via a push notification. Please note that those notification systems operate under their own terms and conditions and, where applicable, as described in their respective privacy notices. Please see our Privacy Notice for how the Company processes personal data in connection with the App.

2.5. Downloaded messages and related chat history are stored locally on the recipient’s Device and remain accessible to that user until deleted from their Device. The Company does not store, and cannot view or retrieve chat data submitted, transmitted or deleted from the Polkadot Network .

2.6. Please note that there is no proactive monitoring, or proactive moderation within the Chat Functionality. Each user is solely responsible for the information they send and for compliance with applicable law. This does not limit the Company’s rights under the EULA (including clauses 6 and 11) to suspend or terminate access to the App.

2.7. The Company disclaims all responsibility and liability for any message delay, loss, duplication or interception; for the operation or availability of the decentralised nodes that operate the Polkadot Network; for the performance of push-notification services; and for any failure resulting from device, network or software issues.

3. Additional Technical Features

3.1. Onboarding and Device Verification

3.1.1. When you first use the App, the onboarding process generates a cryptographic keypair on your Device. The Private Key component of this keypair is backed up in encrypted form to iCloud Keychain (on iOS Devices) or via a split-custody mechanism using Google Drive and Firebase (on Android Devices). You must not delete, alter or otherwise interfere with this backup; doing so may result in permanent and irreversible loss of access to your Wallet and any cryptoassets it contains and we shall not be responsible for any loss of access due to your action.

3.1.2. As part of the onboarding process, the App performs a Proof of Unique Device (“PoUD”) check using Apple App Attest (on iOS Devices) or Google Play Integrity (on Android Devices) to verify that the App is running on a genuine, unmodified Device. This check enforces a limit of one Account per Device.

3.1.3. You acknowledge and agree that: (a) PoUD verification is a condition of Account registration and you will be unable to register an Account if your Device does not pass the PoUD check; (b) the PoUD mechanism relies on attestation services provided by Apple or Google (as applicable), which operate under their own terms and conditions and over which we have no control; and (c) we are not liable for any inability to register an Account resulting from a failed PoUD check, including where such failure arises from Device configuration, operating system modifications or the unavailability of the relevant attestation service.

3.2. Desktop and Web App Pairing (Remote Signing)

3.2.1. The App supports pairing with the Polkadot desktop application and/or web application (“Desktop/Web App”) to enable remote transaction signing (“Pairing”). When Pairing is active, your Device serves as the sole signing authority: all cryptographic keys remain on the Device at all times and are never transmitted to the Desktop/Web App or to any third party.

3.2.2. When you initiate or approve a transaction via the Desktop/Web App, the transaction payload is transmitted to your Device for signing. The signed transaction is then returned to the Desktop/Web App for broadcast to the Polkadot Network. At no point during this process is your Private Key exposed to, or accessible by, the Desktop/Web App.

3.2.3. You are solely responsible for: (a) ensuring the security of the connection between your Device and the Desktop/Web App; (b) verifying the details of any transaction payload before approving it on your Device; and (c) ensuring that Pairing is only established with applications and devices that you trust and control.

3.2.4. We are not responsible for any loss or damage arising from: (a) unauthorised access to a paired session; (b) the approval of a transaction based on an incorrect, misleading or malicious payload transmitted by the Desktop/Web App; or (c) any compromise of the Desktop/Web App or the device on which it is installed.
