3. Scope of Services & Architecture

3.1 Components of the Kraster ecosystem. The Services consist of the following core components: the Kraster Device, which performs all cryptographic operations locally; the Kraster App, which acts as a communication interface; the Firmware, embedded and digitally signed by Kraster; and the Website and online store, which provide informational, purchasing, and support access. Ancillary third-party services (such as payment processors or exchange integrations) may be available within the App but remain the sole responsibility of their respective providers.

3.2 Security model and control limitations. Kraster provides a non-custodial system. All key generation and signing occur within the Device. The App never stores or accesses private keys, PINs, or Seed Phrases. The Website and store do not interact with user wallets or cryptographic material. Users are fully responsible for: • keeping their Device physically secure, • managing backups of their Seed Phrase and PIN, and • protecting against unauthorized access.

3.3 Data Flow and Interoperability. The App communicates with the Device through an encrypted local connection. Transaction data is prepared in the App, signed on the Device, and returned to the App for broadcast. Kraster does not intercept or modify this flow. For blockchain data (balances, confirmations, gas), the App may connect to third-party node providers. These services are independent, and Kraster makes no guarantees as to their availability or accuracy.

3.4 Software and firmware updates. Kraster maintains a secure infrastructure for App and firmware updates. All updates are digitally signed and must be installed from official sources. Installing unauthorized software or failing to apply security updates may: compromise device integrity, void the warranty, and result in loss of functionality. Kraster may discontinue support for outdated software in line with its End-of-Life (EOL) policy.

3.5 Control over Blockchain Networks. Kraster does not operate or control any blockchain network, validator, or node infrastructure. We cannot: • reverse or cancel transactions, • influence gas fees, or • guarantee network performance or confirmation times. Blockchain operations depend on decentralized networks beyond Kraster`s control. The Services are provided `as is,` without warranty against protocol-level events (e.g., forks, delays, reorganizations).

3.6 Service availability and modifications. Kraster may modify or discontinue certain features of the Services for security, legal, or operational reasons. Temporary interruptions may occur due to maintenance, updates, or third-party service issues. Where legally required or operationally material, Kraster will notify Users via the App, Website, or registered email address.

3.7 Eligibility and intended use. The Services are intended for use by individuals: aged 18 or older (or legal age in their jurisdiction); and legally permitted to use digital asset tools in their country. Unless explicitly authorized by Kraster in writing, Services are for personal, non-commercial use only. Users are responsible for ensuring local legal, regulatory, and tax compliance.

4. User Responsibilities and Security Obligations

4.1 Key security and custody. You are solely responsible for the confidentiality and protection of your Kraster Device, Seed Phrase, PIN, and any credentials linked to your digital assets. Kraster does not store, access, or recover any private keys or Seed Phrases. Loss or compromise of these credentials will result in permanent loss of access to your assets. You must: • generate and store your Seed Phrase securely in an offline medium; • avoid storing or copying it in any digital or online format; • set a strong, confidential PIN and avoid reuse or disclosure; • apply firmware and software updates promptly from official sources; • avoid connecting the Device to untrusted systems or networks. Unauthorized modification, mishandling, or failure to secure the Device or credentials constitutes a material breach of these Terms and may void the warranty. This exclusion shall apply to the extent permitted by applicable consumer protection laws.

4.2 Transaction verification. Before approving any blockchain transaction, you must verify the transaction details on the Device screen. The App may provide a preview, but only the Device display is authoritative. Kraster is not liable for: • user mistakes, incorrect addresses, or fee selection; • malware, phishing, or man-in-the-middle attacks; • any losses resulting from unauthorized or mistaken approvals. Blockchain transactions are irreversible once signed and broadcast.

4.3 Physical handling. You must handle and store the Device in a secure, dry environment and protect it from: • unauthorized access or tampering; • physical damage, moisture, or extreme conditions; • any attempt to open, modify, or repair the Device. In case of suspected compromise, immediately transfer assets using your Seed Phrase and discontinue use of the affected Device.

4.4 Use of app and online interfaces. You are responsible for using the App and Website on secure, up-to-date systems. Always verify that the domain is krasterwallet.com and the connection is encrypted (valid SSL). Kraster is not responsible for any loss or breach resulting from: • use of counterfeit or phishing websites; • compromised user systems; • negligence in following basic cybersecurity practices.

4.5 User accounts. If you create an account via the App or Website (for purchases or updates), you must: • provide accurate and up-to-date contact information; • protect your login credentials; • notify Kraster of any suspected unauthorized access. You are responsible for all activity performed using your account.

4.6 Legal compliance and permitted Use. You may use the Services only in accordance with applicable laws, including export control, sanctions, and anti-money laundering regulations. You must not: use the Services for illegal purposes or infringe third-party rights; access the Services from jurisdictions where use is prohibited by law. Kraster may restrict or terminate access in the event of suspected unlawful use or risk to Service integrity.

4.7 Blockchain operations and fees. You are responsible for all blockchain-related costs, including gas fees and transaction charges. Kraster does not: set or control these fees; reimburse failed, delayed, or overpriced transactions; guarantee successful execution of blockchain operations. Ensure sufficient funds are available in your wallet before initiating any transaction.

5. Transactions and Blockchain Operations

5.1 All transactions initiated via the Device and App are executed directly on decentralized blockchain networks that operate independently of Kraster. Once signed and broadcast, transactions are final and irreversible. Kraster has no ability to cancel, modify, refund, or reverse any transaction. You are solely responsible for verifying all transaction details on the Device before approval.

5.2 The App prepares transaction data, but all cryptographic signing is performed exclusively by the Device. After you confirm a transaction on the Device screen, the signed transaction is returned to the App and submitted to the blockchain via third-party nodes. Kraster does not validate, store, or intercept transaction data and has no control over network confirmation or execution. Network delays or rejections due to congestion or fee levels are expected and outside Kraster`s control.

5.3 You must always verify the recipient address, amount, asset type, and network on the Device display before approving a transaction. The App may display previews, but the Device is the sole authoritative source. Kraster is not liable for: • incorrect addresses, clipboard interference, or user error; • malware, phishing attempts, or manipulated UI; • transactions signed or approved without proper user diligence.

5.4 All blockchain transactions require payment of network fees (`gas`) determined by the blockchain protocol. Any estimates shown in the App are non-binding and may differ from the actual fee charged. Kraster does not influence, receive, or refund such fees. You are solely responsible for ensuring that your wallet contains a sufficient balance to cover all applicable fees before initiating any transaction.

5.5 Blockchain networks are decentralized and not operated by Kraster. Accordingly, Kraster cannot guarantee: • timely inclusion of transactions; • continuous availability of the network; • protection from forks, reorganizations, or consensus failures; • the accuracy of blockchain data received from third-party nodes. Temporary inconsistencies or delays in transaction status or balance display do not indicate any defect in the Services.

5.6 A Fork or chain split occurs when a blockchain undergoes a protocol change resulting in multiple chains. Kraster may, at its discretion, support or decline to support any resulting chain or asset. You are responsible for: verifying asset compatibility with the Device or App; managing assets across chains after a fork or protocol update. Kraster is not liable for loss, duplication, or display errors resulting from forks, upgrades, or incompatible networks.

5.7 The App may use third-party node providers to display balances, confirmations, and network data. These providers are independent of Kraster, and we do not guarantee the accuracy, timeliness, or availability of such data. The blockchain itself remains the only authoritative record of asset ownership and transaction history.

5.8 If supported, interaction with smart contracts or DApps is performed at your sole discretion and risk. Kraster does not audit, validate, or endorse any external contracts, protocols, or services. We are not responsible for any losses resulting from: • defective or malicious smart contracts; • incorrect user input; • failures in gas estimation or transaction execution.

5.9 You acknowledge that blockchain networks may experience: bugs, exploits, validator failures, or consensus errors; double-spend attacks, 51% attacks, or chain halts. Kraster bears no responsibility for losses, discrepancies, or interruptions resulting from such events.

5.10 Kraster is not a custodian, broker, financial intermediary, or payment service provider. You are solely responsible for understanding and complying with local laws and tax obligations. Kraster does not monitor, report, or disclose your transactions to any third party unless legally compelled to do so under applicable law.

6. Software, Firmware Updates and Lifecycle
