Shield GTU on an account

Shield GTU

When you shield an amount on an account, only the account’s credential holder can see the shielded amounts. Other participants in the network will be able to see the shielding transaction, but can’t see the shielded balance or any shielded transfers going in or out of the account. You can’t make shielded transfers on multi-signature accounts, only on accounts with a single credential.

If you have an account with GTU in the shielded balance, you can’t add new credentials to that account. Furthermore, once a shielded transfer has been logged on an account, you’ll no longer be able to add more credentials to that account. This is also the case even if you unshield all GTU in the shielded balance.

  1. Go to Accounts and select the relevant account.

  2. Select Shield.

  3. Enter the amount of GTU that you want to shield. If the amount you want to transfer including the transfer fee exceeds the amount in your account, you’ll see a message saying Insufficient funds. This means that there’s not enough GTU in the account and you’ll have to change the amount. Also, the amount must be greater than zero. Select Continue.

  4. There’s a message saying Waiting for device. Please connect your Ledger. Connect the Ledger to the computer and enter your PIN on Ledger.

  5. Press the right button to navigate to the Concordium app, and then press both buttons to open the app. The Ledger says Concordium is ready. Wait for the message in the Desktop Wallet saying Ledger Nano S is ready and select Submit.

  6. Review the transaction on the Ledger and verify that the information matches the Transaction details in the Desktop Wallet. Navigate to the right and verify the sender address is correct. Continue navigating to the right and verify that the amount and the recipient address are correct.

  7. Press both buttons to sign the transaction. In the Desktop Wallet, you can see that the transfer has been submitted to the chain. Select Finish. When the transaction has been finalized, you can see the shielded balance on the account overview.

Unshield GTU

The steps to unshield GTU are similar to the ones to shield GTU.

  1. Select Shielded Balance on the relevant account, and then select Unshield.

  2. Enter the amount of GTU that you want to unshield, and then select Continue.

  3. Follow steps 4-7 as described above. When the transaction has been finalized, you can see that the shielded balance has changed, and you can see the the amount you unshielded in the Transfers list.
