Terms and Conditions


Last updated: October 25th, 2023

The Self-Custody Website is provided by and you are contracting with Self-Custody AG, Neuhofstrasse 12, 6340 Baar, Switzerland (hereinafter referred to as “Self-Custody”, “we”, “us”, “our”). The present terms and conditions (“Terms”) set out the agreement under which we may provide you with use of the Self-Custody Website and our services associated within the Self-Custody Website.

If you have any questions about these Terms, please contact our Support team at [email protected]. Self-Custody provides its services exclusively on the basis of these Terms. Details regarding our authorised representative and further information can be found in the Contact Us section of our website.

1. Scope

These Terms apply to every user of Self-Custody (hereinafter referred to as “you” or “User”). For more detailed information on how we handle your personal data we refer to our Data Privacy Notice (“Privacy Notice”) which can be found by clicking on this link. No other terms or conditions apply to the provision of the Self-Custody Website and its associated services, the Bitcoin Self-Custody described in section 3 (the “Services”), except as set out in the Terms, unless we have agreed otherwise with you in writing.

2. Your agreement with Self-Custody

2.1 Creating a Self-Custody User Account

The use of the Services is not intended to be available to Users for persons under the age of 18 (or the relevant age limit applicable at their place of residence). If you are under the age, you are unfortunately not permitted to use the Services.

In order to use the Services, you must (1) satisfy the age requirements, (2) be authorised to enter into a legally binding contract with us and not be prevented from doing so by applicable laws, and (3) be located in a country where our Services are available. 

Self-Custody will provide you with the Services, as soon as you create a user account (“Self-Custody User Account”). To create a Self-Custody User Account, you must provide us with all the data as required in the registration form. By accepting these Terms and creating a Self-Custody User Account, you receive a limited, non-exclusive, revocable license to use the Services  in its current version for non-commercial purposes. A separate declaration of acceptance by Self-Custody is not required. You must personally create a Self-Custody User Account, as we do not accept registrations carried out by third parties on your behalf. We reserve the right to refuse to accept your registration where we have reasonable cause, or should we believe that by doing so would result in us being in breach of any applicable law or regulation.

2.2 Single-Signature and Multi-Signature Accounts

During the creation of the Self-Custody User Account you will be asked to choose between a Single-Signature Account or a Multi-Signature Account. A Single-Signature Account is an account where only one key is necessary to sign a transaction. A Multi-Signature Account is an account where 2 out of 3 keys are necessary in order to sign a transaction. In case you decide to have a Multi-Signature Account, you will be asked to invite additional two persons to create a Self-Custody User Account. You and the other two persons will have access to the same Bitcoin Self-Custody and all have the same functionalities available. Your Self-Custody User Account will only be successfully created after the two persons have finished the Self-Custody User Account creation process.

2.3 Accessing the Services within the Self-Custody Website

After you have created a Self-Custody User Account (see section 2.1) you will have access to the full contents and services of the Services (see sections 3).

The fees for the Services are displayed in the Self-Custody Website. The fees for the Services shall be calculated in accordance with our fee schedule (“Fee Schedule”). Self-Custody may propose modifications to the Fee Schedule at any time, upon at least thirty (30) days’ advance notice of such modifications to the User. Self-Custody charges annual fees. The first fees are due within three (3) days after you opened a Self-Custody User Account. You agree that Self-Custody will automatically send you a payment request for due fees three (3) days before each year ends. Self-Custody retains the right to deactivate your Self-Custody User Account, including your Bitcoin Self-Custody, if your fees are overdue.

3. The Bitcoin Self-Custody

3.1 Description of the Service

You may use the Bitcoin Self-Custody to send or receive crypto assets such as virtual currencies like Bitcoin (“Virtual Currency”) to or from other persons and wallets. 

The Bitcoin Self-Custody is an online Virtual Currency storage service which allows you to hold, send and receive a Virtual Currency. The Bitcoin Self-Custody is a self-custodial account. This means that only you have access to your private key. Self-Custody does not have access to your private key. Self-Custody only provides the infrastructure on high-security servers in Zug, Switzerland where a copy of your encrypted Backup Recovery Key is stored, which allows you to restore your Bitcoin Self-Custody in a third party wallet (see section 3.3). 

The Bitcoin Self-Custody is not a payment instrument, e-money wallet or a similar instrument and it does not offer a trading facility for Virtual Currency or other digital assets (e.g Tokens). The Bitcoin Self-Custody can only be used to hold, send and receive a Virtual Currency. You will appreciate that your Bitcoin Self-Custody is connected directly to the underlying Blockchain so that no transaction will pass through Self-Custody.

You are the owner of the Virtual Currency stored in your Bitcoin Self-Custody. You can access all information related to your Bitcoin Self-Custody through your Self-Custody User Account opened on the Self-Custody Website. 

Your Bitcoin Self-Custody’s initial balance will be zero. You can add a Virtual Currency to the Bitcoin Self-Custody by following the steps described on the Self-Custody Website.

The use of auto trade robots (bots) or any other kind of automatic trading (buy, sell) software or devices on the Self-Custody Website is strictly forbidden. Self-Custody reserves the right to suspend your accounts without notification, if suspected of such activities.

3.2 Encryption & Backup

To ensure secure use of the Bitcoin Self-Custody, you are required to choose a secure password in order to encrypt the Bitcoin Self-Custody. This password is required in addition to the Self-Custody login.

Additionally, you are requested to create a backup recovery key for additional safety against data loss (the “Backup Recovery Key”). The Backup Recovery Key allows you to restore the Bitcoin Self-Custody should your device be stolen or you want to restore the Bitcoin Self-Custody on a new or other device. The Backup Recovery Key is a mnemonic phrase in a certain order. You are solely responsible for remembering this mnemonic phrase and keeping it secure outside the Self-Custody Website. You are aware and acknowledge that the loss of your data, in particular of your private key, may lead to a complete loss of the Virtual Currency stored in your Bitcoin Self-Custody. 

After creating your Self-Custody User Account and sending your Virtual Currencies to your Bitcoin Self-Custody, Self-Custody automatically stores an encrypted copy of your Backup Recovery Key in a completely offline server in Zug, Switzerland. This offline server is never connected to the internet besides when Self-Custody moves the encrypted copy from the online server to the offline server which takes a few seconds. As long as your Backup Recovery Key is stored in the offline server you won’t be able to send Virtual Currencies from your Bitcoin Self-Custody to a third party wallet. In order to do so, you need to deactivate the “offline” mode. With this step, your Backup Recovery Key is moved to the online server, which is constantly connected to the internet and allows you to instantly send Virtual Currencies.

3.3 Sending and Receiving Virtual Currency

You may use the Bitcoin Self-Custody to send or receive the Virtual Currency to or from other persons. Your use of the Bitcoin Self-Custody may be limited subject to account verification requirements.

You can always check out our website www.selfcustody.net for additional details on how to use your Bitcoin Self-Custody, manage your contacts, send transactions and how to create various reports on your accounts and transactions.

3.4 Two-Step Authentication

Self-Custody keeps the right to ask for a two-step authentication for sensitive procedures (e.g sending Virtual Currencies, etc). In case a two-step-authentication is required, a verification code is sent to the email address which is registered under your Self-Custody User Account. After receiving the verification code, you need to fill out the code on the Self-Custody Website in order to confirm the respective step.

3.5 Transaction fees

Transaction fees are charged in the Virtual Currency to your Bitcoin Self-Custody immediately and automatically once your transaction or other use of our service is completed. Self-Custody does not charge any transaction fees as the transaction occurs directly from your Bitcoin Self-Custody to the underlying Blockchain. Self-Custody does not compensate you for any such fees, therefore the amount of funds you add/withdraw to/from your Bitcoin Self-Custody may actually be smaller than the nominal amount you intend to transact.

4. Security of your data and updates

Self-Custody will continuously update (including security updates) the Self-Custody Website to the extent necessary to keep the digital Services in conformity and inform you accordingly, expand or modify the Services  to respond to changing User interests, to fix technical errors and to introduce new features. We therefore recommend that you keep the Self-Custody Website, all other software on your device and your operating system up to date (for example, with respect to the latest security patches).

The data transferred between the Self-Custody Website and the Self-Custody’ systems is done via TLS/SSL connection. Your Self-Custody User Account is stored securely by Self-Custody in a data center in Zug, Switzerland certified according to the PCI-DSS and ISO27001 standards. Self-Custody is entitled to adapt the technical measures for the protection of your data from time to time (e.g. due to further development of the state of the art or due to current knowledge in the field of cryptography).

We may communicate with you via various methods including email. Although all of our emails are scanned for viruses, it is recommended that any attachment(s) be scanned by yourself as we cannot be held liable for any loss or damage caused by software viruses. If you choose to communicate with us via email, please be aware that email communications without the use of encryption, may not be the safest method of communication and third parties may be able to access it. Self-Custody is not liable for such access. If you wish to guarantee the safety and confidentiality of any information you send to us via email, encryption methods should be used.

Self-Custody provides you with the Self-Custody Website in its current version. You are not entitled to request the maintenance of the Self-Custody Website in the state it was in when you accepted these Terms or at a later date. Self-Custody reserves the right to offer the Self-Custody Website only for certain operating systems and/or only for certain versions of operating systems. We advise you to always keep your operating system up to date.

We do not share your data with unauthorised third parties. Your information may be shared with authorised third parties in some situations, particularly when it is strictly necessary to provide and improve our services. Under no circumstances will we sell your data to third parties. You can find further information in our Privacy Notice which can be found by clicking on this link.

We will need to carry out planned and, occasionally, unscheduled technical maintenance from time to time, during which you will not be able to use the Self-Custody Website. 

We cannot guarantee that use of the Self-Custody Website will be uninterrupted or error-free. As with most services that are being provided online, we also cannot guarantee that the Self-Custody Website is free of any viruses or other malicious code, although we do everything we can to prevent this happening. If any defects occur, we request that you document these and send them to Self-Custody in writing. Among other things, your information will allow us to improve our service. Please tell us about this using [email protected]. This does not affect your legal rights in relation to faulty or mis-described products.

We may adapt the technical and organizational measures we use to protect your information (to reflect improvements in technology, for example) as long as this does not reduce the level of protection we apply to your information

5. Obligations of Self-Custody

We are under a legal duty to supply services that are in conformity with these Terms. Nothing in these Terms will affect the legal rights that you have under applicable laws and which cannot be waived by contract.

Self-Custody is committed to providing support for enquiries via email. Self-Custody will normally respond to your enquiries within 2 working days. Please note that depending on the nature and extent of your question, an answer or solution may not be provided within 2 working days.

6. Obligations of the User

You agree that you will:

  • not try to access the account of a third party via the Services;
  • not transfer or try to transfer viruses, trojans, worms or other malicious code into our systems;
  • not hack, reverse engineer or manipulate our systems or try to do so;
  • not use the Services in a way that breaches any laws or regulations, or that might put us in breach of any laws or regulations;
  • not violate any contractual agreements with the providers of your account when using the Services ; and
  • keep your data in your User Account and the Services up to date.

If we have reason to think that you are in breach of any of these Terms, we can temporarily suspend your access to the Services while we investigate the matter further. Self-Custody will inform you about the suspension of your account, unless by doing so we would be violating any of our legal obligations. Should we decide that you have not breached these Terms, we will restore your access to the Services as quickly as we can.

You are responsible for keeping your individual login details secret and secure and for protecting them from being obtained or used by any other party. You should not write them down or store them in a way that allows any other party to gain access to the Self-Custody Website. You are responsible for contacting us immediately in the event of the loss or theft, or in the event of your knowledge of any misuse of, or unauthorised access to your Self-Custody User Account. You may contact our support team via [email protected]. Security instructions for handling your password and the security code can be found on our website.

7. Our liability

We are responsible to you for the loss or damage you suffer that is a foreseeable result of us breaching these Terms, except for where it is excluded by this section or otherwise in these Terms. Loss or damage is foreseeable if it is either obvious that it will happen or known by both you and us at the time you entered into these Terms that it might happen.


We are not legally allowed to exclude or limit our liability where it would be unlawful to do so. This includes liability for death or personal injury caused by our negligence or the negligence of our employees, agents or subcontractors, for fraud or fraudulent misrepresentation, or where the Self-Custody Website is not fit for purpose, of satisfactory quality or not as described. The aforesaid limitations of liability shall not apply to any mandatory statutory liability, in particular to liability under the German Product Liability Act (Produkthaftungsgesetz), and liability for culpably caused injuries of life, body or health. In addition, such limitations of liability shall not apply if and to the extent Self-Custody has assumed a specific guarantee.

You are aware and acknowledge that the loss of your data, in particular of your private key, may lead to a complete loss of the Virtual Currency stored in your Bitcoin Self-Custody. Self-Custody is not liable for any damage related to such data losses that are not attributable to our fault.

8. Data Protection

You may find more information regarding data protection in our Privacy Notice which may be found in this link

The services performed by us under these Terms are relying on the use of distributed ledger technologies, generally known under the name of “Blockchain” (“DLT-based Services”).

Transaction data related to your use of DLT-based Services may be recorded on a public ledger. Such public ledgers are designed and intended to immutably record transactions across wide networks of computer systems. Many such ledgers are open to forensic analysis (e.g. by law enforcement authorities or third parties) which can lead to de-anonymisation and the unintentional revelation of private financial information, especially when data stored on the public ledger is combined with data from other sources.

Because public ledgers are decentralised or third-party networks that are not controlled or operated by us, we are not able to erase, modify, or alter your personal data from such networks, which will limit your rights to delete or modify your personal data as described in the Privacy Notice.

9. How we can change the Services or these Terms

We can change these Terms or change the Services for any of the following reasons:

  • to add new features to the Services, in particular in order to add storage functionality for additional types of digital assets other than Virtual Currency;
  • to withdraw any features or functionality;
  • to reflect changes (including expected changes) to or restrictions imposed by laws or regulations applicable to our Services, including any decision of a court, regulator or ombudsman;
  • to reflect any changes to our costs of providing the Services; or
  • to respond to any changes of the technology we use or might want to use.

As these Terms have no expiry date and we hope that you will use the Services for a long time into the future, we may need to amend these Terms or the Services where we have a good reason that is not listed above. 

We will tell you about these amendments by:

  • bringing any amendments to your attention when you next access the Self-Custody Website and asking you to confirm your agreement to the changes; or
  • emailing you information about the amendment. We will use the email address you have provided. If we use an email to tell you about the amendment, we will aim to give you at least 30 days advance notice prior to the amendment coming into effect.

If you do not want to accept the amendment, you can object in text form (e.g., by sending an email to [email protected]) within 30 days of receipt of the email. Otherwise the amendments shall be deemed approved. Self-Custody shall specifically point this consequence out when announcing the amendments. On receipt of such an objection, Self-Custody is entitled to terminate any agreement related to it before the changes take effect in line with Section 11.1, with the result that your Self-Custody User Account will be deleted. For the objection to be deemed made in time, the dispatch date shall be decisive. In case of objection, the original terms and conditions shall continue to apply until termination.

If you do not object to the amendments beforehand, the amendment will come into effect after the notice period (where notified by email) or immediately (where notified through the Self-Custody Website).
