+
+## Introduction
+Cobo Vault runs as a standalone application on customized hardware and Android 8.1 Oreo (Go Edition).  This app performs:
+1. Interaction with user. 
+2. Interaction with mobile application [Cobo Vault Mobile](https://cobo.com/hardware-wallet/cobo-vault-app) via QR code. 
+3. Interaction with Secure Element (SE) via serial port, the firmware of SE is opensourced at [cobo-vault-se-firmware](https://github.com/CoboVault/cobo-vault-se-firmware). The transaction data will be signed by this SE and the generated signature will be send back to this application. This signature and other necessary message will be displayed to user via QR code. Users use their mobile or desktop application to acquire signed transaction and broadcast it. 
+
+The application of this hardware wallet is programmed with Java language. The transaction related work is done by Typescript opensourced at [crypto-coin-kit](https://github.com/CoboVault/crypto-coin-kit). The framework, J2V8 is used as the bridge between Java and Typescript. 
+
+
+## Clone
+
+    git clone git@github.com:CoboVault/cobo-vault-cold.git --recursive
+
+## Build

+<strong>Hardware and App Terms of Service</strong>
+
+<strong>Last Updated: [Oct. 18, 2018]</strong>
+
+These Terms govern your use of our App and Hardware. Please read these Terms of Service (the "<strong>Terms</strong>") and our Privacy Policy (<u>https://webview.cobo.com/internal/vault/pp</u>) ("<strong>Privacy Policy</strong>") carefully because they govern your use of our mobile device application ("<strong>App</strong>"), our Wallet (as defined below), and any equipment supplied by Cobo for use with the Wallet and the App ("<strong>Hardware</strong>"). These Terms and the documents that are referred to herein constitute a binding obligation between you and Cobo Global HK Limited, the seller of Cobo. To make these Terms easier to read, App, Wallet, Hardware and our associated services are collectively called the "<strong>Services</strong>." A "<strong>Virtual Currency</strong>" is any blockchain-based currency or token such as Bitcoin. The use of our website located at <u>https://cobo.com</u> (the "Site") is governed by our general website terms of use <u>https://webview.cobo.com/internal/des/toc</u>.
+
+<strong>1. Agreement to Terms.</strong> By using our Services, you agree to be bound by these Terms. If you don't agree to be bound by these Terms, do not use the Services. If you are accessing and using the Services on behalf of a company (such as your employer) or other legal entity, you represent and warrant that you have the authority to bind that company or other legal entity to these Terms. In that case, "you" and "your" will refer to that company or other legal entity. These Terms constitute the entire agreement between Cobo and you with respect to this Services and it supersedes all prior or contemporaneous communications, agreements and understandings between Cobo and you with respect to the subject matter hereof.
+
+<strong>2. Privacy Policy.</strong> Please refer to our Privacy Policy for information on how we collect, use and disclose information from our users. You acknowledge and agree that your use of the Services is subject to our Privacy Policy.
+
+<strong>IMPORTANT NOTICE REGARDING ARBITRATION: WHEN YOU AGREE TO THESE TERMS YOU ARE AGREEING (WITH LIMITED EXCEPTION) TO RESOLVE ANY DISPUTE BETWEEN YOU AND COBO THROUGH BINDING, INDIVIDUAL ARBITRATION RATHER THAN IN COURT. PLEASE CAREFULLY REVIEW THE "DISPUTE RESOLUTION" SECTION BELOW FOR DETAILS REGARDING ARBITRATION (INCLUDING THE PROCEDURE TO OPT OUT OF ARBITRATION).</strong>
+
+<strong>3. Changes to Terms or Services.</strong> We may update the Terms at any time, in our sole discretion. If we do so, we'll let you know either by posting the updated Terms on the Site or through other communications. It's important that you review the Terms whenever we update them or you use the Services. If you continue to use the Services after we have posted updated Terms, you are agreeing to be bound by the updated Terms. If you don't agree to be bound by the updated Terms, then, except as otherwise provided the "Dispute Resolution" Section you may not use the Services anymore. Because our Services are evolving over time we may change or discontinue all or any part of the Services, at any time and without notice, at our sole discretion.
+
+<strong>4. Who May Use the Services?</strong>
+
+<strong>(a)</strong> Eligibility. You may use the Services only if you are 18 years or older, capable of forming a binding contract with Cobo) and are not barred from using the Services under applicable law.
+
+<strong>(b)</strong> Registration and Your Information. If you want to use certain features of the Services you'll have to create an account ("<strong>Account</strong>"). You can do this via the Site or through your account with certain third-party social networking services such as Facebook or Twitter (each, an "<strong>SNS Account</strong>"). If you choose the SNS Account option we'll create your Account by extracting from your SNS Account certain personal information such as your name and email address and other personal information that your privacy settings on the SNS Account permit us to access.
+
+<strong>(c)</strong> Accuracy of Account Information. It's important that you provide us with accurate, complete and up-to-date information for your Account and you agree to update such information to keep it accurate, complete and up-to-date. If you don't, we might have to suspend or terminate your Account. You agree that you won't disclose your Account password to anyone and you'll notify us immediately of any unauthorized use of your Account. You're responsible for all activities that occur under your Account, whether or not you know about them.
+
+<strong>5. Hardware, Wallet and Description of Services.</strong>
+
+<strong>(a)</strong> General. Cobo offers a hierarchical deterministic Virtual Currency wallet that implements the BIP44 blockchain protocol ("<strong>Wallet</strong>"). It is powered by Hardware in which a tablet-like device containing a security chip randomly generates a 24-word mnemonic phrase ("<strong>Mnemonic Phrase</strong>") and master seed to derive pairs of private and public keys to manage Virtual Currencies.
+
+<strong>(b)</strong> Use of the Services with Virtual Currency. Please note that neither the Wallet nor do any of the Services "hold" Virtual Currency, but rather facilitates the interaction between the holder of the Virtual Currency and the underlying blockchain network that processes the transactions. Public keys allow you to receive and deposit Virtual Currency, whereas private keys allow you to send Virtual Currency outside of your account. To complete a Virtual Currency transaction, a user downloads the App on a mobile device, begins a transaction, and generates a QR code that is scanned by the Wallet, which will then  complete the transaction by providing the private key for signature authority (provided however, that the user must control the Mnemonic Phrase and any other necessary passwords and details). After the transaction is signed by the Wallet, it generates a QR code that is scanned by the App on the mobile device, which then broadcasts the transaction to the blockchain via the internet. The App can only be used in conjunction with the Wallet and for no other purpose.
+
+<strong>(c)</strong> Passwords. The Mnemonic Phrase and any password that you select in connection with your use of the Wallet is not known or otherwise stored by Cobo. Using the Mnemonic Phrase, your private key can be recovered on any BIP44-compatible wallet. IF YOU LOSE OR OTHERWISE FORGET YOUR MNEMONIC PHRASE, THEN NEITHER YOU NOR COBO WILL BE UNABLE TO RETRIEVE YOUR PRIVATE KEY, as the Wallet hardware is designed to resist tampering. The Wallet is designed to be separated and unconnected from the internet to provide further security against hacking, however no solution is theft-proof, including the Wallet.
+
+<strong>(d)</strong> Firmware. In order to support certain functionality, such as new forks of Virtual Currency, firmware upgrades will be needed to be installed onto the Wallet per any instructions by Cobo.
+
+<strong>(e)</strong> Sole Responsibility. YOU ARE SOLELY RESPONSIBLE FOR MAINTAINING THE SECURITY AND AVAILABILITY OF YOUR MNEMONIC PHRASE, PRIVATE KEY AND ANY OTHER PASSWORDS ASSOCIATED WITH YOUR WALLET. IT IS RECOMMENDED THAT YOU TAKE APPROPRIATE SAFEGUARDS TO ENSURE SUCH SECURITY, WHICH MAY INCLUDE MAINTAINING A SAFETY DEPOSIT BOX AT A REPUTABLE FINANCIAL INSTITUTION.  FAILURE TO DO SO MAY RESULT IN THE LOSS OF CONTROL OF VIRTUAL CURRENCY ASSOCIATED WITH THE WALLET.
+
+<strong>6. Virtual Currency Transactions.</strong>
+
+<strong>(a)</strong> Transactions. In order to be completed, all proposed Virtual Currency transactions must be confirmed and recorded in the Virtual Currency public ledger associated with the relevant Virtual Currency network. Such networks are decentralized, peer-to-peer networks supported by independent third-parties, which are not owned, controlled or operated by Cobo. Virtual Currency networks are operated by decentralized networks of independent third parties. Cobo has no control over any Virtual Currency network and therefore cannot and does not ensure that any transaction details you submit via the Services will be confirmed via the relevant Virtual Currency network. You acknowledge and agree that the transaction details you submit via the Services may not be completed, or may be substantially delayed, by the Virtual Currency network used to process the transaction.
+
+<strong>(b)</strong> No Storage or Transfer of Title of Virtual Currency. A Virtual Currency is an intangible, digital asset. They exist only by virtue of the ownership record maintained in the underlying Virtual Currency network. The Services do not store, send or receive Virtual Currency. Any transfer of title that might occur in any Virtual Currency occurs on the decentralized ledger within the Virtual Currency network and not within the Services. We do not guarantee that the Service can affect the transfer of title or right in any Virtual Currency.
+
+<strong>(c)</strong> No Cancellations or Modifications. Once transaction details have been submitted to the Virtual Currency network via the Services, the Services cannot assist you to cancel or otherwise modify your transaction details. Cobo has no control over any Virtual Currency network and does not have the ability to facilitate any cancellation or modification requests.
+
+<strong>7. Disclaimers.</strong>
+
+<strong>(a)</strong> No Password Retrieval. Cobo does not receive or store your Wallet Password, Mnemonic Phrase, or the unencrypted keys and addresses. Therefore, we cannot assist you with Wallet Password retrieval. Our Services cannot generate a new Password for your Wallet. You are solely responsible for remembering your Wallet Password and Mnemonic Phrase. If you have not safely stored a backup of any Wallet Addresses and Mnemonic Phrase maintained in your Wallet, you accept and acknowledge that any Virtual Currency you have associated with such Wallet Addresses will become inaccessible if you do not have your Wallet Password and/or Mnemonic Phrase.
+
+<strong>(b)</strong> Discontinuation of the Services. We may, in our sole discretion and without cost to you, with or without prior notice and at any time, modify or discontinue, temporarily or permanently, any portion of our Services. You are solely responsible for storing, outside of the Services, a backup of any Mnemonic Phrase, private key or other associated passwords, as you may not be able to access Virtual Currency maintained in your Wallet in the event that we discontinue or deprecate the Services.
+
+<strong>(c)</strong> Relationship. Nothing in these Terms is intended to nor shall create any partnership, joint venture, agency, consultancy or trusteeship, you and Cobo being with respect to one another independent contractors.
+
+<strong>(d)</strong> Accuracy of Information; Responsibility for Activities. You represent and warrant that any information you provide via the Services is accurate and complete. You accept and acknowledge that Cobo is not responsible for any errors or omissions that you make in connection with any Virtual Currency transaction initiated via the Services, for instance, if you mistype a public key or otherwise provide incorrect information. We strongly encourage you to review your transaction details carefully before completing them via the Services. You hereby accept and acknowledge that you take responsibility for all activities that occur under your Wallet and accept all risks of any authorized or unauthorized access to your Wallet, to the maximum extent permitted by law.
+
+<strong>(e)</strong> Taxes. It is your responsibility to determine what, if any, taxes apply to the transactions you for which you have submitted transaction details via the Services, and it is your responsibility to report and remit the correct tax to the appropriate tax authority. You agree that Cobo is not responsible for determining whether taxes apply to your Virtual Currency transactions or for collecting, reporting, withholding or remitting any taxes arising from any Virtual Currency transactions.
+
+<strong>(f)</strong> Disclaimer. THE SERVICES, HARDWARE AND CONTENT ARE PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND. WITHOUT LIMITING THE FOREGOING, TO THE FULLEST EXTENT OF THE LAW, WE EXPLICITLY DISCLAIM ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, QUIET ENJOYMENT AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE. We make no warranty that the Services will meet your requirements or be available on an uninterrupted, secure, or error-free basis. We make no warranty regarding the quality, accuracy, timeliness, truthfulness, completeness or reliability of any Content.

+
+<strong>(c)</strong> THE EXCLUSIONS AND LIMITATIONS OF DAMAGES SET FORTH ABOVE ARE FUNDAMENTAL ELEMENTS OF THE BASIS OF THE BARGAIN BETWEEN COBO AND YOU.
+
+<strong>17. Governing Law and Forum Choice.</strong> These Terms and any action related thereto will be governed by the Federal Arbitration Act, federal arbitration law, and the laws of the Hong Kong Special Administrative Region of the People's Republic of China, without regard to its conflict of laws provisions. Except as otherwise expressly set forth in the "Dispute Resolution" section below, the exclusive jurisdiction for all Disputes (defined below) that you and Cobo are not required to arbitrate will be a court of competent jurisdiction located in Hong Kong, and you and Cobo each waive any objection to jurisdiction and venue in such courts. Notwithstanding the above, if you are a citizen of the People's Republic of China and are located outside the United States, you consent that any dispute arising from or in connection with these Terms and Conditions shall be submitted to China International Economic and Trade Arbitration Commission (CIETAC) for arbitration, which shall be conducted in Beijing in accordance with the CIETAC's arbitration rules in effect at the time of applying for arbitration.
+
+<strong>18. Dispute Resolution.</strong> The following terms of this "Dispute Resolution" section only apply if you are an individual who is using the Services and Content for your own personal use and are not representing a legal entity.
+
+<strong>(a)</strong> Mandatory Arbitration of Disputes. We each agree that any dispute, claim or controversy arising out of or relating to these Terms or the breach, termination, enforcement, interpretation or validity thereof or the use of the Services or Content (collectively, "<strong>Disputes</strong>") will be resolved <strong>solely by binding, individual arbitration and not in a class, representative or consolidated action or proceeding</strong>. However, if for any reason a Dispute proceeds in court rather than in arbitration, <strong>you and we each waive any right to a jury trial.</strong>
+
+<strong>(b)</strong> Exceptions and Opt-out. As limited exceptions to Section 19(a) above: (i) you may seek to resolve a Dispute in small claims court if it qualifies; and (ii) we each retain the right to seek injunctive or other equitable relief from a court to prevent (or enjoin) the infringement or misappropriation of our intellectual property rights. In addition, <strong>you will retain the right to opt out of arbitration entirely and litigate any Dispute,</strong> if you provide us with written notice of your desire to do soby email at <u>support@cobo.com</u> or by regular mail at [FLAT/AM A 20/F KIU FU COMMERCIAL BLDG, 300 LOCKHART ROAD, WAN CHAI, HONG KONG] within thirty (30) days following the date you first agree to these Terms.
+
+<strong>(c)</strong> Starting Arbitration. If you want to begin arbitrating a Dispute, you must send a letter to us at the following address [FLAT/AM A 20/F KIU FU COMMERCIAL BLDG, 300 LOCKHART ROAD, WAN CHAI, HONG KONG] requesting arbitration and describing the Dispute. If we want to begin arbitrating a Dispute, we'll send such a letter to you at the email address or street address that you provided.
+
+<strong>(d)</strong> Conducting Arbitration and Arbitration Rules. The arbitration will be conducted by the American Arbitration Association ("<strong>AAA</strong>") under its Consumer Arbitration Rules (the "<strong>AAA Rules</strong>") or a comparable arbitral body (e.g., JAMS), in the event the AAA is unable to conduct the arbitration). The AAA Rules are available at <u>www.adr.org</u> or by calling 1-800-778-7879. The arbitration may be conducted in writing, remotely (e.g., by videoconference) or in-person in the county where you live (or at some other location that we both agree to).
+
+<strong>(e)</strong> Arbitration Costs. Payment of all filing, administration and arbitrator fees will be governed by the AAA Rules. We'll pay for all filing, administration and arbitrator fees and expenses if your Dispute is for less than $10,000 USD, unless the arbitrator finds your Dispute frivolous. If we prevail in arbitration we'll pay all of our attorneys' fees and costs and won't seek to recover them from you. If you prevail in arbitration you will be entitled to an award of attorneys' fees and expenses to the extent provided under applicable law.
+
+<strong>(f)</strong> Class Action Waiver.   <strong>YOU AND COBO AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING</strong>.  Further, if the parties' dispute is resolved through arbitration, the arbitrator may not consolidate another person's claims with your claims, and may not otherwise preside over any form of a representative or class proceeding.  If this specific provision is found to be unenforceable, then the entirety of this Dispute Resolution section shall be null and void.
+
+<strong>(g)</strong> Effect of Changes on Arbitration. Notwithstanding the provisions of "Changes to Terms or Services" section above, if Cobo changes any of the terms of this "Dispute Resolution" section after the date you first accepted these Terms (or accepted any subsequent changes to these Terms), you may reject any such change by sending us written notice (including by email to <u>support@cobo.com</u>) within 30 days of the date such change became effective, as indicated in the "Last Updated" date above or in the date of Cobo s email to you notifying you of such change. By rejecting any change, you are agreeing that you will arbitrate any Dispute between you and Cobo in accordance with the terms of this "Dispute Resolution" section as of the date you first accepted these Terms (or accepted any subsequent changes to these Terms).
+
+<strong>19. General Terms.</strong>
+
+<strong>(a)</strong> Entire Agreement. These Terms constitute the entire and exclusive understanding and agreement between Cobo and you regarding the Services and Content, and these Terms supersede and replace any and all prior oral or written understandings or agreements between Cobo and you regarding the Services and Content. With the exception of any provisions in the "Class Action Waiver" section of these Terms, if any provision of these Terms is held invalid or unenforceable by an arbitrator or a court of competent jurisdiction, that provision will be enforced to the maximum extent permissible and the other provisions of these Terms will remain in full force and effect. You may not assign or transfer these Terms, by operation of law or otherwise, without Cobo's prior written consent. Any attempt by you to assign or transfer these Terms, without such consent, will be null. Cobo may freely assign or transfer these Terms without restriction. Subject to the foregoing, these Terms will bind and inure to the benefit of the parties, their successors and permitted assigns.
+
+<strong>(b)</strong> Survival. Upon any termination, discontinuation or cancellation of the Services or your Account, the following Sections will survive: "Hardware, Wallet and Description of Services" (as to the "Passwords" and "Sole Responsibility" subsections); "Content Ownership, Responsibility and Removal (as to the "Our Content Ownership", "Rights in User Content Granted by You", "Your Responsibility for User Content", and "Removal of User Content" subsections) "Disclaimers", "Feedback", "Indemnity", "Limitation of Liability", "Governing Law and Forum Choice", "Dispute Resolution", and "General Terms".
+
+<strong>(c)</strong> Notices. Any notices or other communications provided by Cobo under these Terms, including those regarding modifications to these Terms, will be given: (i) via email; or (ii) by posting to the Services. For notices made by e-mail, the date of receipt will be deemed the date on which such notice is transmitted.
+
+<strong>(d)</strong> Waiver of Rights. Cobo's failure to enforce any right or provision of these Terms will not be considered a waiver of such right or provision. The waiver of any such right or provision will be effective only if in writing and signed by a duly authorized representative of Cobo. Except as expressly set forth in these Terms, the exercise by either party of any of its remedies under these Terms will be without prejudice to its other remedies under these Terms or otherwise.
+
+<strong>20. Contact Information.</strong> If you have any questions about these Terms or the Services, please contact Cobo at <u>support@cobo.com</u>.

+<strong>CAUTION:</strong>
+<strong>Read this section before using your device.</strong>
+
+<strong>1.</strong>Cobo Vault is a hierarchical deterministic (HD) wallet complaint with BIP 32/39/44. It uses a Secure Element for true random number generation (TRNG), from which a master private key is derived. The master private key can be used to manage virtually unlimited pairs of private and public keys for different cryptocurrencies. Users can also import an existing recovery phrase into the Cobo Vault.
+
+<strong>2.</strong> The master private key is encrypted and securely stored within the Secure Element. You will need to carefully write down the recovery phrase when it is generated during Cobo Vault initialization.
+
+<strong>3.</strong>The recovery phrase enables final ownership of all digital assets under the master private key in the Cobo Vault. If it is  lost or forgotten, all assets will be irretrievable.
+
+<strong>4.</strong>After recording your recovery phrase upon initialization of the device, store it where it in a secure location and consider using Cobo Tablet to give it a high degree of permanence.
+
+<strong>5.</strong>If the device is lost or broken, all digital assets under the master private key can be recovered with the recovery phrase on any device or software that supports the BIP 39 protocol.
+
+<strong>6.</strong>The Hidden Vaults feature allows you to create separate, concealed Vaults that can be accessed with Passphrases. Once a Hidden Vault is created, its Passphrase cannot be changed. If the Passphrase (and/or recovery phrase) is forgotten or lost, the Hidden Vault and all of its assets will be irretrievable.
+
+<strong>7.</strong>In addition to the recovery phrase and Passphrase, there is a system password, pattern unlock, and fingerprint sensor (Cobo Vault Pro only):
+<strong>a.</strong>System password unlocks screen and signs transactions.
+<strong>b.</strong>Pattern unlock unlocks screen and may be used to reset the system password.
+<strong>c.</strong>Fingerprint sensor unlocks screen and signs transactions.
+
+<strong>8.</strong>After 12 incorrect pattern unlock attempts, users will be required to unlock with the system password. After 5 incorrect system password attempts, the device will be wiped. If your device is wiped, your Cobo Vault can only be restored with the recovery phrase. The system password also can only be reset by entering the recovery phrase. If both the system password and recovery phrase are lost, all assets will be irretrievable. This is a preventative measure against theft.
+
+<strong>9.</strong>Do not use the device if Web Authentication on the official website fails or if the system warns that the device may have been tampered with. Cobo Vault implements these measures to protect you from supply chain attacks.
+
+<strong>10.</strong> The Cobo Vault Pro is equipped with an anti-tampering self-destruct mechanism. If the device is disassembled, the recovery phrase and master seed will automatically be wiped from the Secure Element. Due to hardware constraints, it is not guaranteed this mechanism will function as intended beyond 5 years of operation. Cobo Vault Pro will remain operational, but this security mechanism may not. We recommend replacing your device after 5 years of usage to ensure this mechanism is working properly.
+<strong>Note:</strong> Cobo Vault Essential does not have this function.

+<strong>服务条款</strong>
+
+<strong>更新日期：【2018年10月18日】</strong>
+
+本条款涵盖您对Cobo Global HK Ltd.（以下称为“Cobo”）的应用和硬件的使用。请您通过Cobo网站 <u>https://cobo.com</u>（以下简称"<strong>本网站</strong>"）仔细阅读以下服务条款（以下简称"<strong>本条款</strong>"）及<strong>隐私政策</strong>（<u>https://webview.cobo.com/internal/vault/pp</u>）。您使用手机应用（"应用"）、钱包（定义见下文）及Cobo提供的与钱包及应用有关的任何设备（以下简称"<strong>硬件</strong>"）时，适用于本条款及隐私政策。本条款及本条款中提及的其他协议对您和 Cobo 均具有约束力。为本条款之目的，本网站、应用、钱包、硬件及我们的其他相关服务合称为"<strong>本服务</strong>"。"<strong>虚拟货币</strong>"指基于区块链的货币，例如比特币。
+
+<strong>1. 接受本条款。</strong> 当您使用我们的服务时，即视为您接受了本条款并受本条款约束。如果您不同意本条款，请勿使用本服务。如果您代表公司（如您的雇主）或其他实体访问及使用本服务，您承诺您有权代表该公司或实体受本条款的约束。在该种情形下，"您"应指您代表的公司或实体。本条款构成您与Cobo之间关于本服务的所有约定，并取代之前Cobo与您之间关于本服务的所有交流、协定及理解。
+
+<strong>2. 隐私政策：</strong> 请浏览我们的隐私政策，了解我们怎样收集、使用及披露用户信息。您理解并同意您使用本服务受制于隐私政策的规定。
+
+<strong>特别提请您注意：当您同意本条款时，即视为您同意通过仲裁而非诉讼解决您与 Cobo 之间的争议（例外情况除外）。请您仔细阅读下文 "争议解决" 条款了解仲裁的相关规定（包括拒绝仲裁的程序）。</strong>
+
+<strong>3. 本条款或本服务的修改。</strong> 我们可能会不时修改本条款。如果我们修改了本条款，我们将通过在网站公布修改后的条款或其他方式使您知悉。请您注意频繁浏览本条款。如果您在本条款修改后仍继续使用本服务，即视为您接受了修改后的条款并受其约束。如果您不同意本条款的修改，除"争议解决"条款规定的以外，您应停止使用本服务。我们可能会在未通知您的情况下不时更改或停止某部分服务。
+
+<strong>4. 哪些用户能使用本服务？</strong>
+
+<strong>(a)</strong> 行为能力。您使用本服务时年龄应不小于18周岁并未被适用法律禁止使用本服务。
+
+<strong>(b)</strong> 注册及信息。如果您使用服务的特定功能，您需要先创建一个账户（"<strong>账户</strong>"）。您可以通过本网站或第三方社交网站例如facebook或twitter（单独称为"<strong>SNS 账户</strong>"）来创建账户。如果您选择通过SNS账户来创造账户，我们可能会从您的SNS账户中提取您的名字、邮箱地址以及您在SNS账户的隐私设置中允许被访问的其他个人信息。
+
+<strong>(c)</strong> 账户信息准确性。您应在账户中向我们提供准确、完整、最新的信息，并应及时更新相应信息。如果您未按照上述要求提供信息，我们可能会暂停或终止您对账户的使用。您同意您不会向任何人泄露您的账户密码，并就他人未授权使用您账户的情形及时通知我们。无论您是否明知，您都应当对您账户下发生的所有活动负责。
+
+<strong>5. 硬件、钱包及本服务描述。</strong>
+
+<strong>(a)</strong> 一般规定。Cobo按照BIP44区块链协议的规定提供分级的、确定的虚拟货币钱包（以下简称"<strong>钱包</strong>"）。该钱包由包含安全芯片的平板设备进行技术支持，该安全芯片可任意创造由24个字节组成的助记词（以下简称为"<strong>助记词</strong>"）及主种子株，用以获得管理虚拟货币的私钥及公钥。
+
+<strong>(b)</strong> 虚拟货币服务。请您注意钱包及任何其他服务是为了便于虚拟货币持有者与处理交易的潜在区块链网络进行联系，但钱包及任何其他服务本身不持有虚拟货币。您可以使用公钥接收及存储虚拟货币，使用私钥在您的账户以外发送虚拟货币。为完成虚拟货币交易，用户需在移动设备上下载应用、开启交易并生成供钱包扫描的二维码，钱包将通过提供私钥获得签名权限来完成交易（前提是用户必须掌控助记词及其他必要密码）。钱包在交易中签名后，会生成一个由移动端应用扫描的二维码，并将该交易通过网络在区块链进行公布。应用只能用于与钱包有关的用途。
+
+<strong>(c)</strong> 密码。Cobo不会获取也不储存助记词及您使用钱包时创建的密码。您可以使用助记词在任何BIP44兼容的钱包上找回私钥。如果您丢失或忘记了您的助记词，您和Cobo都无法找回您的私钥。为采取反黑客措施，钱包与网络分离设计，但钱包本身无法防盗。
+
+<strong>(d)</strong> 固件。为支持特定功能，如支持新的币种，您可以根据Cobo指示，在钱包上进行固件升级。
+
+<strong>(e)</strong> 个人责任。您应自行为您的助记码、私钥和其他与钱包有关的密码安全负责。我们建议您采取适当的安全措施确保助记码、私钥及其他密码的安全，包括存放在金融机构的保管箱中。如您未采取安全措施，可能会导致您丢失虚拟货币。
+
+<strong>6. 虚拟货币交易。</strong>
+
+<strong>(a)</strong> 交易。为完成交易，所有拟进行的虚拟货币交易都必须在与虚拟货币网络有关的公共账上进行确认和记录。该等网络是由独立第三方支持的去中心化的、点对点的网络，非由Cobo所有、控制或运营。虚拟货币网络由独立第三方的去中心化网络运营。Cobo无法控制虚拟货币网络，因此无法确保您通过本服务提交的交易将会通过相关的虚拟货币网络被确认。您理解并同意您通过本服务提交的交易可能由于虚拟货币网络的原因为无法完成或延迟。
+
+<strong>(b)</strong> 不储存或转让虚拟货币。虚拟货币是无形的数字资产，并于潜在的虚拟货币网络中记录其所有权。本服务本身不存储、发送或接收虚拟货币。虚拟货币的转让发生在去中心化的分类账中而非本服务中。我们无法保证本服务能够影响虚拟货币所有权或其他权利的转让。
+
+<strong>(c)</strong> 无取消或更改。一旦您通过本服务向虚拟货币网络提交交易，该交易无法通过本服务取消或更改。Cobo对虚拟货币网络没有控制权，也无法提交取消或更改交易的请求。
+
+<strong>7. 免责声明。</strong>
+
+<strong>(a)</strong> 无密码找回服务。Cobo不接收或存储您的钱包密码、助记词或密钥及地址。因此，我们无法协助您找回钱包密码。我们的服务无法为您的钱包创造新密码。您应牢记您的钱包密码及助记词。如果您未能为您的钱包地址及助记词备份，您理解并同意，在未能提供钱包密码及/或助记词的情况下，您将无法访问与该等钱包地址相关联的虚拟货币。
+
+<strong>(b)</strong> 服务中断。我们可能会在未通知您的情况下，自行决定修改、中断或终止我们的全部或部分服务。您应在服务器外部妥善存储、备份您的助记词、密钥或其他关联密码，以防在我们中断本服务时发生您未能通过钱包访问虚拟货币的情形。
+
+<strong>(c)</strong> 关系。本条款的任何规定均不应被视为Cobo与您之间建立了任何合伙、合资、代理、咨询或信托关系，您和Cobo分别为独立的合同相对方。
+
+<strong>(d)</strong> 信息准确性；自行担责。您承诺及保证，您通过本服务提供给我们的信息均为准确、完整的信息。您接受并理解，Cobo不对您在虚拟货币交易中产生的任何错误或疏忽负责，例如，您输入了错误的公钥或提供了不准确的信息。我们强烈建议您在通过本服务完成交易前，仔细确认交易信息。您在此接受并理解，您应对您的钱包账户下发生的任何活动负责，并应在法律允许的最大程度下，承担任何授权或未授权访问您钱包而产生的风险。
+
+<strong>(e)</strong> 税费。您有责任判定您通过本服务提交的交易是否需要缴税并向税务机关缴纳应缴税费。您同意，Cobo没有责任判定您的虚拟货币交易是否需要缴税，也无需向税务机关代扣代缴由于虚拟货币交易而产生的税费。
+
+<strong>(f)</strong> 免责。本服务、硬件及内容均以其原始状态向您提供，Cobo不对本服务、硬件及内容作出任何形式的承诺。在法律允许的最大程度下，我们不对由于在商业惯例或商业习惯中产生的任何默示的适销性承诺、符合特定目的承诺、稳定权承诺、不侵权承诺及其他承诺承担责任。我们不保证本服务能完全满足您的需求，也不对本服务的无干扰性、安全性或零失误性作出承诺。我们不对内容的质量、精确性、时间、真实性、完整性或可靠性作出任何承诺。
+
+<strong>8. 反馈。</strong> 我们欢迎您对我们的服务提出任何意见或建议（"<strong>反馈</strong>"）。您可以通过发送邮件至<u>support@cobo.com</u> 来提交您的反馈。您在此不可撤销地无偿授予我们对于您提出的反馈进行转授权、复制、修改、制造衍生产品或其他的非排他的、可转让的、全球性的、永久性的知识产权相关权利。
+
+<strong>9. 内容所有权、责任及移除权。</strong>
+
+<strong>(a)</strong> 定义。为本条款之目的：(i)"<strong>内容</strong>"应指通过本服务显示、提供或可以访问的任何文本、商标、服务标识、商号、域名、网站链接、图标及图形、图像、音乐、软件、音频、视频、作品或其他信息、资料。(ii)"<strong>用户内容</strong>"应指账户持有人（包括您）通过本服务上传的内容。内容包括但不限于用户内容。
+

+
+<strong>(c)上述责任限制条款是您和 Cobo 订立本条款的基础。</strong>
+
+<strong>17. 适用法律及管辖法院。</strong>本条款应适用于美国联邦仲裁法及香港特别行政区法律（不包括冲突法）。除本条款"争议解决"条款另有规定外，Cobo与您之间无法通过仲裁解决的争议均应由位于香港的有管辖权的法院管辖，您和Cobo在此放弃对于上述管辖法庭及法庭地的异议。尽管存在上述规定，若您为中华人民共和国的公民且并未在美国居住，您同意任何由本条款引起的或与本条款有关的争议均应提交中国国际经济贸易仲裁委员会，按其届时有效的仲裁规则在北京仲裁解决。
+
+<strong>18. 争议解决。</strong> 下列争议解决条款仅适用于您为自身目的而使用本服务及内容的情形，不适用于您作为公司或其他法律实体的代表而使用本服务及内容的情形。
+
+<strong>(a)</strong> 强制仲裁。我们和您在此一致同意，任何由于本条款产生的或与本条款有关的争议、索赔或冲突、与本条款违约、终止、执行、解释及有效性相关的争议或与使用本服务或内容有关的争议（合称为"<strong>争议</strong>"）， <strong>均应通过单个仲裁员仲裁的方式而非集体诉讼、代表诉讼或合并诉讼等诉讼程序解决</strong> 。仲裁裁决为终局的，且对双方均具有约束力。若由于任何原因，上述争议通过诉讼而非仲裁解决， <strong>则我们和您在此明示放弃陪审团审判的权利</strong> 。
+
+<strong>例外情形。</strong> 尽管存在上述第18（a）条的规定， (i)您可以在条件允许的情况下选择在小额诉讼法院解决争议；(ii)我们和您均保留向法庭寻求禁令或其他临时性救济的权利。除此之外，您可以决定拒绝以仲裁的方式解决争议，如果您选择拒绝以仲裁的方式解决争议，请于您接受本条款之日起三十（30）日内发送邮件至<u>support@cobo.com</u>通知我们，或发送快递至下列地址：FLAT/AM A 20/F KIU FU COMMERCIAL BLDG, 300 LOCKHART ROAD, WAN CHAI, HONG KONG。
+
+<strong>(b)</strong> 启动仲裁。如您希望开启仲裁程序，请提前书面通知我们请求仲裁并列明争议事项，并将上述书面通知邮寄至下列地址：FLAT/AM A 20/F KIU FU COMMERCIAL BLDG, 300 LOCKHART ROAD, WAN CHAI, HONG KONG。如果我们希望开启仲裁程序，我们会向您提供给我们的邮箱或地址发出书面通知。
+
+<strong>(c)</strong> 仲裁程序及仲裁规则。争议将提交美国仲裁协会，根据其消费仲裁规则（"AAA规则"）进行仲裁，或在美国仲裁协会无法进行仲裁的情况下，提交其他类似仲裁协会（例如JAMS）进行仲裁。您可登陆<u>www.adr.org</u> 或致电 1-800-778-7879 查看AAA规则。仲裁可以以书面形式、远程形式（例如，视频会议）或在您居住的城市或我们一致同意的其他地点以面对面形式进行。
+
+<strong>(d)</strong> 仲裁费。AAA规则具体对仲裁费用作出了规定。若争议标的少于10,000美元，我们将承担所有的仲裁费用，但仲裁员判定争议无意义的情况除外。如果仲裁庭支持我们的仲裁请求，我们将会自行支付律师费并不向您进行追偿。如果仲裁庭支持您的仲裁请求，则在适用法律允许的情况下，您有权获得律师费及其他花费的补偿。
+
+<strong>(e)</strong> 集体诉讼弃权。 <strong>您和 Cobo 在此同意，您仅以个人身份而非以集体诉讼代表身份提起诉讼。</strong> 除此之外，若通过仲裁解决争议，则仲裁员不会将您的仲裁请求与第三人的仲裁请求合并审理，也不会开启任何形式的代表人仲裁或集体仲裁。若本特别规定被认定为不可执行，则本条款的争议解决条款应被视为完全无效。
+
+<strong>(f)</strong> 仲裁条款的修改。尽管存在"条款或服务更改"条款的规定，若Cobo在您接受了本条款（或接受了本条款的后续更新版本）后修改本"争议解决"条款，您可以在该修改生效之日（修改生效之日将于文首"更新日期"处显示，或以Cobo邮件通知您更改"争议解决"章节的日期为准）起30天内向我们发送书面通知（包括发送邮件至[support@cobo.com](support@cobo.com)）拒绝该等修改。拒绝该等修改后，您同意您与Cobo之间的争议将通过您初次接受本条款（或接受本条款的后续更新版本）时"争议解决"章节规定的争议解决方式进行解决。
+
+<strong>19. 一般条款</strong>
+
+<strong>(a)</strong> 完整协议。本条款构成Cobo与您关于本服务及内容的所有合意，并取代先前所有与之相关的口头或书面沟通、协议。除本条款的"集体诉讼弃权"条款外，若本条款的任何其他条款被仲裁员或有管辖权的法庭认定为无效或不可执行，则该等条款应在法律允许的最大程度下进行执行，且其余条款应继续有效。未经Cobo事先书面同意，您不得转让您在本条款项下的权利或义务，否则任何转让权利或义务的行为均应视为无效。Cobo有权转让本条款项下的权利或义务。受限于上述规定，本条款应对双方及其继受人、受让人具有约束力。
+
+<strong>(b)</strong> 继续有效。当本服务或您的账户终止、停止或取消时，下列条款应继续有效："硬件、钱包及服务描述"（针对"密码"及"独立责任"条款）；"内容所有权、责任及移除权"（针对"内容所有权"、"用户内容移除"条款）；"免责条款"、"反馈"、"赔偿条款"、"责任限制"、"适用法律及管辖法院"、"争议解决"及"一般条款"。
+
+<strong>(c)</strong> 通知。Cobo将通过下列方式发布有关本条款的通知：(i)发送邮件；(ii)在本服务中进行公告。对于通过邮件发送的通知，收到通知的时间应为通知发出的时间。
+
+<strong>(d)</strong> 弃权。Cobo不执行本条款的任何权利或条款不应被视为Cobo对该等权利或条款的弃权。该等权利或条款的弃权仅应在Cobo授权代表书面签署弃权声明时方为有效。除本条款另有规定外，一方根据本条款对于某种救济权利的行使不影响其对其他救济权利的行使。

+<strong>安全须知</strong>
+<strong>1.</strong>Cobo金库采用分层确定性协议的解决方案，创建金库将通过加密芯片生成单一随机助记词及主私钥，并由此主私钥生成树状结构储存多组私钥和公钥，管理不同币种。用户也可以导入已有的遵循BIP39协议的助记词钱包到本金库使用。
+
+<strong>2.</strong>用户的助记词及主私钥经过加密后，保存于Cobo金库安全芯片内，金库生成助记词后，请仔细抄写备份。
+
+<strong>3.</strong>主私钥对Cobo金库内的数字资产拥有绝对控制权，一旦丢失，用户将永远无法恢复其中的资产。
+
+<strong>4.</strong>初次创建金库时生成的助记词，为用户找回主私钥的唯一途径，请务必牢记并妥善保存。建议使用Cobo助记板备份，增加安全性。
+
+<strong>5.</strong>如果Cobo金库遗失或损坏，可通过助记词在任何支持BIP39协议的设备或软件上恢复原Cobo金库内的全部数字资产。
+
+<strong>6.</strong>Cobo金库支持创建基于密语的隐藏金库。用户在创建隐藏金库后，其对应的密语不可修改。如果密语（或原助记词）遗忘，隐藏金库将无法恢复，其中存储的资产也将无法取回。
+
+<strong>7.</strong>除助记词和Cobo密语外，用户在使用Cobo金库过程中还会接触其他三类密码：
+<strong>a.</strong>系统密码：用于解除屏幕锁定和签名。
+<strong>b.</strong>手势密码：仅用于解除屏幕锁定，可以通过系统密码修改手势密码。
+<strong>c.</strong>指纹密码（仅限专业版）：用于解除屏幕锁定和签名
+
+<strong>8.</strong>如手势密码连续12次输入错误，可通过系统密码解锁屏幕；如系统密码连续5次输入错误，金库将恢复出厂设置。一旦恢复出厂设置，用户只能通过导入助记词恢复。如果同时遗忘助记词和系统密码，资产将无法找回。
+
+<strong>9.</strong>为保护您的数字资产安全，Cobo金库设计有多重安全验证及防护措施，当官网校验失败（详细使用请参见快速向导）或系统提示Cobo金库被攻击时，请勿继续使用该设备，以防供应链攻击。
+
+<strong>10.</strong>为保护您的数字资产安全，Cobo金库专业版设计有拆机自毁机制，一旦拆机，安全芯片内的助记词及主私钥即被清空，以此确保您的资产安全。防拆电路有效工作年限为5年，防拆电路失效后不影响用户正常使用设备，但会降低设备安全性，建议用户适时更换新设备。
+<strong>注明：</strong>Cobo金库标准版无此功能。
