Terms of Service

Last update: 22.2.2024

Welcome! Taler Systems SA (“we,” “our,” or “us”) provides a payment service through our Internet presence (collectively the “Services”). Before using our Services, please read the Terms of Service (the “Terms” or the “Agreement”) carefully.


This section provides a brief summary of the highlights of this Agreement. Please note that when you accept this Agreement, you are accepting all of the terms and conditions and not just this section. We and possibly other third parties provide Internet services which interact with the Taler Wallet’s self-hosted personal payment application. When using the Taler Wallet to interact with our Services, you are agreeing to our Terms, so please read carefully.


These terms outline approved uses of our Services. The Services and these Terms are still at an experimental stage. If you have any questions or comments related to this Agreement, please send us a message to legal@taler-systems.com. If you do not agree to this Agreement, you must not use our Services.

How you accept this policy

By sending funds to us (to top-up your Taler Wallet), you acknowledge that you have read, understood, and agreed to these Terms. We reserve the right to change these Terms at any time. If you disagree with the change, we may in the future offer you with an easy option to recover your unspent funds. However, in the current experimental period you acknowledge that this feature is not yet available, resulting in your funds being lost unless you accept the new Terms. If you continue to use our Services other than to recover your unspent funds, your continued use of our Services following any such change will signify your acceptance to be bound by the then current Terms. Please check the effective date above to determine if there have been any changes since you have last reviewed these Terms.


We will try to transfer funds that we hold in escrow for our users to any legal recipient to the best of our ability and within the limitations of the law and our implementation. However, the Services offered today are highly experimental and the set of recipients of funds is severely restricted. The Taler Wallet can be loaded by exchanging fiat currencies against electronic coins. We are providing this exchange service. Once your Taler Wallet is loaded with electronic coins they can be spent for purchases if the seller is accepting Taler as a means of payment. We are not guaranteeing that any seller is accepting Taler at all or a particular seller. The seller or recipient of deposits of electronic coins must specify the target account, as per the design of the Taler protocol. They are responsible for following the protocol and specifying the correct bank account, and are solely liable for any losses that may arise from specifying the wrong account. We will allow the government to link wire transfers to the underlying contract hash. It is the responsibility of recipients to preserve the full contracts and to pay whatever taxes and charges may be applicable. Technical issues may lead to situations where we are unable to make transfers at all or lead to incorrect transfers that cannot be reversed. We will only refuse to execute transfers if the transfers are prohibited by a competent legal authority and we are ordered to do so.

When using our Services, you agree to not take any action that intentionally imposes an unreasonable load on our infrastructure. If you find security problems in our Services, you agree to first report them to security@taler-systems.com and grant us the right to publish your report. We warrant that we will ourselves publicly disclose any issues reported within 3 months, and that we will not prosecute anyone reporting security issues if they did not exploit the issue beyond a proof-of-concept, and followed the above responsible disclosure practice.


You agree to pay the fees for exchanges and withdrawals completed via the Taler Wallet (“Fees”) as defined by us, which we may change from time to time. With the exception of wire transfer fees, Taler transaction fees are set for any electronic coin at the time of withdrawal and fixed throughout the validity period of the respective electronic coin. Your wallet should obtain and display applicable fees when withdrawing funds. Fees for coins obtained as change may differ from the fees applicable to the original coin. Wire transfer fees that are independent from electronic coins may change annually. You authorize us to charge or deduct applicable fees owed in connection with deposits, exchanges and withdrawals following the rules of the Taler protocol. We reserve the right to provide different types of rewards to users either in the form of discount for our Services or in any other form at our discretion and without prior notice to you.

Eligibility and Financial self-responsibility

When you setup a Taler Wallet, you are strongly advised to follow the precautionary measures offered by the software to minimize the chances to losse access to or control over your Wallet data. We will not be liable for any loss or damage arising from your failure to comply with this paragraph.

Governing law, Waivers, Severability and Assignment

No matter where you’re located, the laws of Switzerland will govern these Terms. If any provisions of these Terms are inconsistent with any applicable law, those provisions will be superseded or modified only to the extent such provisions are inconsistent. The parties agree to submit to the ordinary courts in Zurich, Switzerland for exclusive jurisdiction of any dispute arising out of or related to your use of the Services or your breach of these Terms.

Our failure to exercise or delay in exercising any right, power, or privilege under this Agreement shall not operate as a waiver; nor shall any single or partial exercise of any right, power, or privilege preclude any other or further exercise thereof.

You agree that we may assign any of our rights and/or transfer, sub-contract, or delegate any of our obligations under these Terms.

If it turns out that any part of this Agreement is invalid, void, or for any reason unenforceable, that term will be deemed severable and limited or eliminated to the minimum extent necessary.
