Send and decrypt a shielded transfer

Prerequisites

  • You must have a shielded amount of CCD on the account you want to make the shielded transfer from. See Shield CCD on an account.

Note

You can’t make shielded transfers on multi-signature accounts.

Send a shielded amount of CCD

When you make a shielded transfer, the amount you transfer is only known to you and the recipient. However, on the blockchain, it’s possible to see which accounts are involved in the transfer.

  1. Go to Accounts and select the account you want to make the transfer from.

  2. Select Shielded balance on the account.

  3. Select Send. In Send shielded funds, enter the amount of CCD that you want to send.

  4. Enter a Memo if you want to send a message to the recipient along with the shielded amount. Note that there’s a fee associated with sending a memo and the fee depends on the size of the memo in bytes.

Warning

Transaction memos are public and visible on the blockchain, and they are permanent and can’t be deleted. Therefore, carefully review all information before you submit the memo to the blockchain.

  1. Select the recipient of the CCD, and then select Continue.

  2. In the Desktop Wallet there’s a message saying Waiting for device. Please connect your Ledger. Connect the Ledger to your computer, and then enter your PIN code on the Ledger.

  3. On the Ledger, there’s a message saying Concordium. Press both buttons. The Ledger says Concordium is ready, and in the Desktop Wallet, there’s a message saying Ledger Nano S is ready.

  4. In the Desktop Wallet, select Submit. There’s a message saying Waiting for the user to finish the process on the device.

  5. Press both buttons on the Ledger to confirm the decryption.

  6. On the Ledger there’s a message saying Concordium is ready, and then it says Review transaction. Using the right button, you now have to navigate through the following information to verify that it’s correct and matches the transaction details in the Desktop Wallet:

    • Shielded transfer: this is the type of transaction. Because the amount is encrypted, the Ledger can’t display the actual amount that’s going to be transferred.

    • Sender: this is the sender account.

    • Recipient: this is the recipient account.

  7. On the Ledger there’s a message saying Sign transaction. Press both buttons to sign the transaction.

  8. In the Desktop Wallet there’s a message saying Shielded transfer submitted, which means that the transfer has been submitted to the chain.

  9. Select Finish. The transfer is listed in the Transfers list.

Decrypt a shielded amount of CCD

If you have received a shielded transfer, a shield icon is displayed next to the shielded balance. Before you can see the amount that you’ve received, you have to decrypt the shielded transaction.

Any shielded transfers that you’ve already decrypted are visible in the shielded balance.

  1. Select the relevant account, and then select Shielded balance.

  2. The Desktop Wallet says Decrypt shielded balance and Waiting for device. Please connect your Ledger. Connect the Ledger to your computer, and then enter your PIN code on the Ledger.

  3. On the Ledger, there’s a message saying Concordium is ready, and in the Desktop Wallet, there’s a message saying Ledger Nano S is ready.

  4. In the Desktop Wallet, select Decrypt.

  5. On the Ledger, press both buttons to decrypt the amount. In the Desktop Wallet you can now see the amount that you decrypted.
