Terms and conditions for all services and functions#

Parties to the agreement#

When you register with Concordium Legacy Wallet, you enter into an agreement with:

Concordium Software ApS, Amaliegade 4, 1256 København K, Denmark. CVR no.: 42334758. Our email address is contact@concordium.software.

What you need in order to register with Concordium Legacy Wallet#

The following is required to register with Concordium Legacy Wallet:

  • Have a mobile device (e.g., smartphone or tablet). You can see which operating systems can be used at developer.concordium.software.

  • Verify your identity with an identity provider. The identity provider will know the identity of the initial account creator.

You must be at least 18 years old to register.

Registering as a Concordium Legacy Wallet user#

Before you can use Concordium Legacy Wallet, you will need to create a digital identity certificate and create an initial account with an identity provider by following the instructions in the app. An identity provider is a third-party supplier and independent of Concordium Software. The Concordium Legacy Wallet stores data in encrypted form from the identity provider, which Concordium Software does not have access to.

After you have created your digital identity certificate and your initial account, you can create additional accounts (‘regular accounts’) with which you will be able to carry out transactions. Concordium Software may impose a limit to how many accounts you can create in a single Concordium Legacy Wallet. Please note that you can only register one account as the initial account.

Activation code and personal password#

When you register in Concordium Legacy Wallet, you will need to create a personal passcode. If your mobile device supports it, you can subsequently activate your fingerprint or use facial recognition instead of the 6-digit password. You should be aware that all fingerprints/facial recognitions linked to your mobile device can be used to log on to Concordium Legacy Wallet and use the functions. You are therefore obliged to ensure that you have only activated your own fingerprints and your own facial recognition if you want to use them instead of the 6-digit password for access to Concordium Legacy Wallet. Concordium Legacy Wallet does not store your fingerprints or facial recognition.

Other obligations etc.#

You have a duty to ensure that the details you provide are correct and updated at any given time. Your Concordium Legacy Wallet is personal and may be used only by you. You must not disclose your passwords to others, write them down, or save them on your mobile device.

Concordium Legacy Wallet must not be used for illegal activities or purposes.

You must not use Concordium Legacy Wallet in a way that harasses other Concordium blockchain users.

All transaction requests are irreversible. You are yourself responsible for ensuring that the recipient of a transaction via Concordium Legacy Wallet is the intended recipient, and you must verify that the transaction amount is correct. You are responsible for providing the correct account to persons and users who want to transfer funds to you.

To prevent unauthorized use of Concordium Legacy Wallet, you must store your mobile device so that others cannot gain unauthorized access to it. If possible, you should lock your device with a password or keypad lock. Do not disclose the password to third parties.

You are obliged to verify your identity with an identity provider. The identity provider will know the identity of the initial account creator. Your identity can be revealed via the process of disclosing an identity, which can happen under stringent regulations, such as a court order.

You are solely responsible for safekeeping your passwords, PINs, account keys, encryption keys, identity, and any other codes you use to access the Concordium Legacy Wallet or any information, CCD, or voucher. If you lose access to the Concordium Legacy Wallet, private keys, or identity, and you have not separately stored a backup of your accounts and the corresponding password(s), you acknowledge and agree that any tokens you have associated with that account will become inaccessible.

Please note: If you have chosen to use assistants based on speech recognition (e.g., Siri) or patterns of use, this means that information about your use of Concordium Legacy Wallet, including recipients, amounts, and messages, is sent to the provider of the assistant. Your own use of any assistant determines what information is sent. Concordium Legacy Wallet does not send any information.

Baking and Delegation#

Node runners are awarded CCD for running nodes on the Concordium blockchain through a process called baking. Other CCD holders can be rewarded for supporting this process through delegation. The Concordium Legacy Wallet supports management of baking and delegation. Each account can only have one baking or delegation process active at any given time.

While engaged in baking or delegation, the allocated CCD will remain in the account in a locked form. Termination of baking and delegation activates a cool-down period, where baking and delegation is still active, however, the CCDs will not be available in the wallet until the cool-down period is over. Read more about baking and delegation on developer.concordium.software.

When activating, managing and terminating baking and delegation blockchain transaction fees apply. You should always ensure you have sufficient CCD in your available balance to cover these fees.

When activating baking and delegation from the Concordium Legacy Wallet you acknowledge and understand how these features work and that historic performance is not a guarantee for future performance.

Concordium Software does not assume any responsibility for the amount of rewards generated from baking and delegation.


This agreement will apply between you and Concordium Software from your download of the Concordium Legacy Wallet, and until you have completely removed the Concordium Legacy Wallet in its entirety from your device.

The section Concordium Software’s liability for damages shall apply indefinitely.

Any other costs and charges related to your use of the Concordium Legacy Wallet shall be paid by you, including but not limited to costs to the identity provider, if any.

If we introduce new functions, features, products, or services, these may be subject to fees from the start without you receiving any notice of changed terms and conditions. You will always be informed about the fee before you register for the function, feature, product, or service.

Data retention and deletion#

Concordium as a company does not retain and therefore cannot delete any user identifiable information. However, to get an account you must obtain an identity object issued by an identity provider. The identity object contains some user identifiable information such as your name. By default the identity object is only stored encrypted in the wallet and is not visible on-chain. Some data derived from the identity object is sent to the chain, but by default it is not possible to obtain user identifiable information from the information stored in the account on the chain. However, if you choose to reveal any attributes associated with your account, these attributes will be visible on-chain, and can never be deleted.

Governing law and venue#

The agreement and any dispute arising out of the agreement are governed by Danish law and such disputes must be heard by Copenhagen District Court or the jurisdiction of the defendant’s domicile unless otherwise provided by absolute consumer rights in Denmark. This applies without consideration for rules in international private law which may lead to the application of other law than Danish law.
