  • Create multiple User Accounts, unless authorized by us;

  1. Representations and Warranties


You hereby represent and warrant that your use of the Services and/or any of the Platform complies with any and all applicable laws and does not infringe upon any third-party rights, including but not limited to any intellectual property rights, privacy rights and publicity rights, and that your use will not violate these Terms or any such laws and/or rights.


  1. Assumption of Risk


By accessing and using the Services, you represent that you understand the risks inherent to and associated with blockchain networks and cryptographic systems and warrant that you have the technical sophistication and working knowledge required to use, engage, or interact with blockchain networks, cryptographic systems, smart contracts, and digital assets, such as Bitcoin (BTC), and Stacks (STX) (collectively, “Blockchain Technologies”).


By accessing and using the Services in any manner, you (i) acknowledge that you have reviewed publicly-available materials sufficient to ensure that you understand how the Platform and any associated blockchain network(s) function; and (ii) assume all risks associated with such use and the use of any Blockchain Technologies, including, but not limited to, the risk of hardware, software and internet connections failure or problems, the risk of malicious software introduction, the risk that third parties may obtain unauthorized access to information stored within your Wallet, and/or the risk of total loss of any digital assets employed to interact with the Platform (e.g., arising out of or in connection with exploits of and/or defects in any underlying or associated software code, etc.). You accept and acknowledge that we will not be responsible for any communication failures, disruptions, errors, distortions or delays you may experience when using any Blockchain Technologies for processing transactions, however caused.


Additionally, you understand that the markets for digital assets are nascent and highly volatile due to risk factors including (but not limited to) adoption, speculation, technology, security, and regulation. You acknowledge that we are not responsible for any of these variables or risks, do not own or control any blockchain, and cannot be held liable for any resulting losses that you experience as a result of your use of Blockchain Technologies. Accordingly, you understand and agree to assume full responsibility for all of the risks of accessing and using Blockchain Technologies as part of your use of the Services.


4.1 Non-Custodial and No Fiduciary Duties


The Leather is purely a non-custodial application, meaning we do not ever have custody, possession, or control of your digital assets or the digital assets displayed at any time. It further means you are solely responsible for the custody of the cryptographic private keys to the digital asset wallets you hold and you should never share your wallet credentials or seed phrase with anyone. We accept no responsibility for, or liability to you, in connection with your use of a wallet and make no representations or warranties regarding how any of our Products will operate with any specific wallet. Likewise, you are solely responsible for any associated wallet and we are not liable for any acts or omissions by you in connection with or as a result of your wallet  being compromised.  For the avoidance of doubt, any references herein to a "wallet" shall include Leather.

This Agreement is not intended to, and does not, create or impose any fiduciary duties on us. To the fullest extent permitted by law, you acknowledge and agree that we owe no fiduciary duties or liabilities to you or any other party, and that to the extent any such duties or liabilities may exist at law or in equity, those duties and liabilities are hereby irrevocably disclaimed, waived, and eliminated. You further agree that the only duties and obligations that we owe you are those set out expressly in this Agreement.

If we suspend or close your User Account or terminate your use of the Services for any reason, we will provide you with notice of our actions, unless a court order or other legal process prevents or prohibits us from providing you with such notice. You acknowledge that our decision to take certain actions, including limiting access to or suspending your User Account, may be based on confidential criteria that are essential to our risk management and/or security protocols.
