Terms and Conditions

Last updated: January 2024.

1. What is the scope of the Terms?

These Terms and Conditions (“Terms”) become part of any contract (“Agreement”) between you (“you”, “yours” or “User”) and Core Contributors GmbH (“CC”, “we”, “our” or “us”) provided we made these Terms accessible to you prior to entering into the Agreement and you consent to these Terms. We are a limited liability company registered with the commercial register of Berlin Charlottenburg under company number HRB 240421 B, with its registered office at Gontardstraße 11, 10178 Berlin, Germany. You can contact us by writing to info@cc0x.dev.
The Agreement is concluded by using the Mobile App, Web App and/or Browser Extension subject to these Terms. The use of our Services is only permitted to legal entities, partnerships and natural persons with unlimited legal capacity. In particular, minors are prohibited from using our Services.
The application of your general terms and conditions is excluded. Your deviating, conflicting or supplementary general terms and conditions shall only become part of the Agreement if and to the extent that CC has expressly agreed to their application in writing. This consent requirement shall apply in any case, even if for example CC, being aware of your general terms and conditions, accepts payments by the contractual partner without reservations.
We reserve the right to change these Terms at any time and without giving reasons, while considering and weighing your interests. The new Terms will be communicated to you in advance. They are considered as agreed upon if you do not object to their validity within 14 days after receipt of the notification. We will separately inform you about the essential changes, the possibility to object, the deadline and the consequences of inactivity. If you object, the current version of the Terms remains applicable. Our right to terminate the contract according to Clause 8 remains unaffected.

2. What do some of the capitalized terms mean in the Agreement?

“Blockchain” means a mathematically secured consensus ledger such as the Ethereum Virtual Machine, an Ethereum Virtual Machine compatible validation mechanism, or other decentralized validation mechanisms.
“Transaction” means a change to the data set through a new entry in the continuous Blockchain.
“Smart Contract” means a piece of source code deployed as an application on the Blockchain which can be executed, including self-execution of Transactions as well as execution triggered by 3rd parties.
“Token” means a digital asset transferred in a Transaction, including ETH, ERC20, ERC721 and ERC1155 tokens.
“Wallet” means a cryptographic storage solution permitting you to store cryptographic assets by correlation of a (i) Public Key and (ii) a Private Key, or a Smart Contract to receive, manage and send Tokens.
“Recovery Phrase” means a series of secret words used to generate one or more Private Keys and derived Public Keys.
“Public Key” means a unique sequence of numbers and letters within the Blockchain to distinguish the network participants from each other.
“Private Key” means a unique sequence of numbers and/or letters required to initiate a Blockchain Transaction and should only be known by the legal owner of the Wallet.

3. What are the Services offered?

Our services (“Services”) primarily consist of enabling users to create their Safe Accounts and ongoing interaction with it on the Blockchain.

“Safe Account”

A Safe Account is a modular, self-custodial (i.e. not supervised by us) smart contract-based wallet not provided by CC. Safe Accounts are open-source released under LGPL-3.0.

Smart contract wallet means, unlike a standard private key Wallet, that access control for authorizing any Transaction is defined in code. An example are multi-signature wallets which require that any Transaction must be signed by a minimum number of signing wallets whereby the specifics of the requirements to authorize a Transaction can be configured in code.

Owners need to connect a signing wallet with a Safe Account. Safe Accounts are compatible inter alia with standard private key Wallets such as hardware wallets, browser extension wallets and mobile wallets that support WalletConnect.

“Safe App”

You may access Safe Accounts using the zkLink Safe web app, mobile app for iOS and android, or the browser extension (each a “Safe App”). The Safe App may be used to manage your personal digital assets on Ethereum and other common EVM chains when you connect a Safe Account with third-party services (as defined below). The Safe App provides certain features that may be amended from time to time.

“Third-Party Safe Apps”

The Safe App allows you to connect Safe Accounts to third-party decentralized applications (“Third-Party Safe Apps”) and use third-party services such as from the decentralized finance sector, DAO Tools or services related to NFTs (“Third-Party Services"). The Third-Party Safe Apps are integrated in the user interface of the Safe App via inline framing. The provider of the Third-Party Safe App and related Third-Party Service is responsible for the operation of the service and the correctness, completeness and actuality of any information provided therein. We make a pre-selection of Third-Party Safe Apps that we show in the Safe App. However, we only perform a rough triage in advance for obvious problems and functionality in terms of loading time and resolution capability of the transactions. Accordingly, in the event of any (technical) issues concerning the Third-Party Services, the user must only contact the respective service provider directly. The terms of service, if any, shall be governed by the applicable contractual provisions between the User and the respective provider of the Third-Party Service. Accordingly, we are not liable in the event of a breach of contract, damage or loss related to the use of such Third-Party Service.

4. What do the Services not consist of?

Our Services do not consist of:

activity regulated by the Federal Financial Supervisory Authority (BaFin) or any other regulatory agency in any jurisdiction;
coverage underwritten by any regulatory agency’s compensation scheme;
custody of your Recovery Phrase, Private Keys, Tokens or the ability to remove or freeze your Tokens, i.e. a Safe Account is a self-custodial wallet;
the storage or transmission of fiat currencies;
back-up services to recover your Recovery Phrase or Private Keys, for whose safekeeping you are solely responsible; CC has no means to recover your access to your Tokens, when you lose access to your Safe Account;
any form of legal, financial, investment, accounting, tax or other professional advice regarding Transactions and their suitability to you;
the responsibility to monitor authorized Transactions or to check the correctness or completeness of Transactions before you are authorizing them.

5. What do you need to know about Third-Party Services?

We provide you the possibility to interact with your Safe Account through Third-Party Services. Any activities you engage in with, or services you receive from a third party is between you and that third party directly. The conditions of service provisions, if any, shall be governed by the applicable contractual provisions between you and the respective provider of the Third-Party Service.
The Services rely in part on third-party and open-source software, including the Blockchain, and the continued development and support by third parties. There is no assurance or guarantee that those third parties will maintain their support of their software or that open-source software will continue to be maintained. This may have a material adverse effect on the Services.
This means specifically:

We do not have any oversight over your activities with Third-Party Services especially by using Third-Party Safe Apps, and therefore we do not and cannot make any representation regarding their appropriateness and suitability for you.
Third-Party Services are not hosted, owned, controlled or maintained by us. We also do not participate in the Transaction and will not and cannot monitor, verify, censor or edit the functioning or content of any Third-Party Service.
We have not conducted any security audit, bug bounty or formal verification (whether internal or external) of the Third-Party Services.
We have no control over, do not recommend, endorse, or otherwise take a position on the integrity, functioning of, content and your use of Third-Party Services, whose sole responsibility lies with the person from whom such services or content originated.
When you access or use Third-Party Services you accept that there are risks in doing so and that you alone assume any such risks when choosing to interact with them. We are not liable for any errors or omissions or for any damages or loss you might suffer through interacting with those Third-Party Services, such as Third-Party Safe Apps.
You know of the inherent risks of cryptographic and Blockchain-based systems and the high volatility of Token markets. Transactions undertaken in the Blockchain are irrevocable and irreversible and there is no possibility to refund Token that have been deployed.
You should read the license requirements, terms and conditions as well as privacy policy of each Third-Party Service that you access or use. Certain Third-Party Services may involve complex Transactions that entail a high degree of risk.
If you contribute integrations to Third-Party Services, you are responsible for all content you contribute, in any manner, and you must have all rights necessary to do so, in the manner in which you contribute it. You are responsible for all your activity in connection with any such Third-Party Service.
Your interactions with persons found on or through the Third-Party Service, including payment and delivery of goods and services, financial transactions, and any other terms associated with such dealings, are solely between you and such persons. You agree that we shall not be responsible or liable for any loss or damage of any sort incurred as the result of any such dealings.
If there is a dispute between you and the Third-Party Service provider or/and other users of the Third-Party Service, you agree that we are under no obligation to become involved. In the event that you have a dispute with one or more other users, you release us, our officers, employees, agents, contractors and successors from claims, demands, and damages of every kind or nature, known or unknown, suspected or unsuspected, disclosed or undisclosed, arising out of or in any way related to such disputes and/or our Services.

6. What are the fees for the Services?

The use of the Safe App or Third-Party Safe Apps may cause fees, including network fees, as indicated in the respective app. CC has no control over the fees charged by the Third-Party Services. CC may change its own fees at any time. Price changes will be communicated to the User in due time before taking effect.
The User is only entitled to offset and/or assert rights of retention if his counterclaims are legally established, undisputed or recognized by CC.

7. Are we responsible for the security of your Private Keys, Recovery Phrase or other credentials?

We shall not be responsible to secure your Private Keys, Recovery Phrase, credentials or other means of authorization of your wallet(s).
You must own and control any wallet you use in connection with our Services. You are responsible for implementing all appropriate measures for securing any wallet you use, including any Private Key(s), Recovery Phrase, credentials or other means of authorization necessary to access such storage mechanism(s).
We exclude any and all liability for any security breaches or other acts or omissions, which result in your loss of access or custody of any cryptographic assets stored thereon.

8. Can we terminate or limit your right to use our Services?

We may terminate the Agreement and refuse access to the Safe Apps at any time giving 30 days’ prior notice. The right of the parties to terminate the Agreement for cause remains unaffected. In case of our termination of the Agreement, you may no longer access your Safe Account via our Services. However, you may continue to access your Safe Account and any Tokens via a third-party wallet provider using your Recovery Phrase and Private Keys.
We reserve the right to limit the use of the Safe Apps to a specified number of Users if necessary to protect or ensure the stability and integrity of the Services. We will only be able to limit access to the Services. At no time will we be able to limit or block access to or transfer your funds without your consent.

9. Can you terminate your Agreement with us?

You may terminate the Agreement at any time without notice.

10. What licenses and access do we grant to you?

All intellectual property rights in Safe Accounts and the Services throughout the world belong to us as owner or our licensors. Nothing in these Terms gives you any rights in respect of any intellectual property owned by us or our licensors and you acknowledge that you do not acquire any ownership rights by downloading the Safe App or any content from the Safe App.
If you are a consumer we grant you a simple, limited license, but do not sell, to you the Services you download solely for your own personal, non-commercial use.

11. What can you expect from the Services and can we make changes to them?

Without limiting your mandatory warranties, we provide the Services to you “as is” and “as available” in relation to merchantability, fitness for a particular purpose, availability, security, title or non-infringement.
If you use the Safe App via web browser, the strict liability of CC for damages (sec. 536a German Civil Code) for defects existing at the time of conclusion of the contract is precluded.
The foregoing provisions will not limit CC’s liability as defined in Clause 13.
We reserve the right to change the format and features of the Services by making any updates to Services available for you to download or, where your device settings permit it, by automatic delivery of updates.
You are not obliged to download the updated Services, but we may cease to provide and/or update prior versions of the Services and, depending on the nature of the update, in some circumstances you may not be able to continue using the Services until you have downloaded the updated version.
We may cease to provide and/or update content to the Services, with or without notice to you, if it improves the Services we provide to you, or we need to do so for security, legal or any other reasons.

13. What about our liability to you?

All our liability is excluded, except for the following:

In the event of intent and gross negligence on our part, we are liable for damages – regardless of the legal grounds.
In the event of negligence on our part, we are liable for damages resulting from injury to life, body or health.
In the event of simple negligence on our part, we are only liable for damages resulting from the breach of an essential contractual duty (e.g. a duty, the performance of which enables the proper execution of the contract in the first place and on the compliance of which the contractual partner regularly relies and may rely), whereby our liability shall be limited to compensation of the foreseeable, typically occurring damage. Liability for the violation of a non-essential contractual duty is excluded.
The liability for simple negligence only applies to the extent that we do not offer the Safe App and the Services free of charge (please note, in this context, that any service, network and/or transaction fees may be charged by third parties via the Blockchain and not necessarily by us). Conversely, this means that we are not liable in cases of simple negligence, when you obtain the Safe App or the service from us free of charge.
The limitations of liability according to Clauses 13.2 to 13.4. do not apply as far as we have assumed a guarantee or we have fraudulently concealed a defect in the Services. These limitations of liability also do not apply to your claims according to the Product Liability Act (”Produkthaftungsgesetz”) and any applicable data privacy laws.
If you suffer damages from the loss of data, we are not liable for this, as far as the damages would have been avoided by your regular and complete backup of all relevant data.
In the event of disruptions to the technical infrastructure, the internet connection or a relevant Blockchain that we are not responsible for, we shall be exempt from our obligation to perform. This also applies if we are prevented from performing due to force majeure or other circumstances, the elimination of which is not possible or cannot be economically expected of CC.

14. What about viruses, bugs and security vulnerabilities?

We endeavor to provide our Service free from material bugs, security vulnerabilities or viruses.
You are responsible for configuring your information technology and computer programmes to access our Services and to use your own virus protection software.
If you become aware of any exploits, bugs or vulnerabilities, please inform bounty@safe.global.
You must not misuse our Services by knowingly introducing material that is malicious or technologically harmful. If you do, your right to use our Services will cease immediately.

15. What if an event outside our control happens that affects our Services?

We may update and change our Services from time to time. We may suspend or withdraw or restrict the availability of all or any part of our Services for business, operational or regulatory reasons or because of a Force Majeure Event at no notice.
A “Force Majeure Event” shall mean any event, circumstance or cause beyond our reasonable control, which prevents, hinders or delays the provision of our Services or makes their provision impossible or onerous, including, without limitation:

By using the Services you agree not to hold us liable for any tax liability associated with or arising from the operation of the Services or any other action or transaction related thereto.

17. What if a court disagrees with part of this Agreement?

Should individual provisions of these Terms be or become invalid or unenforceable in whole or in part, this shall not affect the validity of the remaining provisions. The invalid or unenforceable provision shall be replaced by the statutory provision. If there is no statutory provision or if the statutory provision would lead to an unacceptable result, the parties shall enter negotiations to replace the invalid or unenforceable provision with a valid provision that comes as close as possible to the economic purpose of the invalid or unenforceable provision.

18. What if we do not enforce certain rights under this Agreement?

Our failure to exercise or enforce any right or remedy provided under this Agreement or by law shall not constitute a waiver of that or any other right or remedy, nor shall it prevent or restrict any further exercise of that or any other right or remedy.

19. Do third parties have rights?

Unless it expressly states otherwise, this Agreement does not give rise to any third-party rights, which may be enforced against us.

20. Can this Agreement be assigned?
