STEP-BY-STEP GUIDE TO CONCORDIUM DESKTOP WALLET
Concordium is the only public blockchain with a privacy-based protocol-level identification layer. This novel ID layer will enable the addition of user functionalities and a trust environment, essential in the future decentralised blockchain economy. Through its wallet you can not only manage CCD tokens, but also your identities and user attributes.
Concordium Desktop Wallet is a digital wallet that allows you to create and manage your Concordium identities and accounts, with which you can perform different types of transactions, such as saving, sending and receiving CCDs, delegating your funds for staking, etc.
Desktop Wallet also allows the storage of your private keys on a hardware device. Currently, only Ledger Nano S or Nano S Plus (latest version of Desktop Wallet 1.5.0) is supported, but a version for Ledger Nano X is already in the works.

7. Select Set connection. If the connection works correctly, there is a message indicating Successfully connected.
04. Create an identity and an initial account number
Before you can start using a Concordium wallet, you need an initial account and an identity issued by an identity provider. To do this, the identity provider must verify and register the user’s real-world identity. This identification is done when you create the first account in the wallet.
Identities facilitate compliance with relevant regulations, but at the same time protect the privacy of users by not exposing their identity on the blockchain.
The identity of an account owner can only be revealed through the anonymity revocation process, which can only occur in exceptional circumstances, for example, if the authorities have detected suspicious activity on the account and requires action by one or more anonymity revocers and the identity provider that issued the account identity.
The process of verifying the user’s real identity generally requires taking photographs or scanning identification documents, such as a passport.
After verification of the user’s identification documents and attributes, the identity provider issues an identity certificate.
Before you start, you need a Ledger hardware device that is configured and ready to use.
- To create an identity if you do not already have one, access the Identities menu option:
2. Select Request new if you do not have any other identity in Concordium:
3. Enter a name for your identity and then enter a name for your initial account. Select Continue.
4. Select an identity provider:
5. Connect your Ledger hardware device and enter your PIN code into it.
In Desktop Wallet, a message will appear asking you to open the Concordium application in Ledger. On the Ledger, press both buttons when Concordium is displayed. The Ledger will display the text: Concordium is ready.
On the Desktop Wallet, a message will appear stating: Ledger Nano S is ready or Ledger Nano S Plus is ready. Select Submit.
6. Press both buttons to confirm the following items in the Ledger:
- Create credential (each credential is assigned a number): Press the right button and then both buttons to confirm Accept.
- Public key: Press both buttons to accept.
- Check that the public key in the Ledger corresponds to the public key in the Desktop Wallet. Use the right button to navigate through the key. — Press both buttons to confirm, and then under Desktop Wallet, select Continue.
- The Ledger will prompt Review identity provider information. Press both buttons and then press the right button to navigate through the public key and verify that it matches the information in the Desktop Wallet. Press both buttons to confirm.
7. Verify that the signature threshold in the Ledger matches the threshold in the Desktop Wallet. Press the right button and then press both buttons to sign the identity provider information.
8. In Desktop Wallet, the New Identity page will be displayed.
9. Enter the identity verification information and select Send. This information will vary depending on the identity provider. The identity provider sends the identity to the blockchain. When the initial account is created in a finalised block on the blockchain, the identity provider confirms the identity and, after confirmation, a green checkmark next to the Concordium logo is displayed on the identity.
10. Select Finished. When you have created more accounts, you will be able to recognise your initial account by the identity text next to the name.
The initial account linked to the identity will be created automatically, it is possible to create more accounts later in the Accounts menu.
Congratulations! You now have your Concordium Desktop Wallet ready to start using it!
