Use the Ardor wallet
Verify your address
Your address is displayed on the Ardor wallet. You can use it to receive ARDR, crypto assets and any other child chain tokens of the platform (ie: IGNIS). It can be used for any other transaction in the Ardor platform such as sending messages, approvals, asset issuance and buy and sell orders
For checking your address with the ledger wallet, click on the following link in the wallet (in green):
A modal pop-up will appear with the box "Verify", click on it:
A "Verify Address" will open:
When we click on "Verify", our address will be displayed on the ledger:
To send tokens, press Send, then enter the amount, the receiving address, click on calculate fee and finally click on the Submit button:
- Verify and confirm all transaction details:
- Press the right button on your device to navigate to display the transaction details (ie: Chain&TxnType, Amount, Destination Fee, Apendages). For instance as shown in the following images:
- In the last transaction detail, you can click on the right button to sign the transaction.
In case the transaction has apendages, each one has a number that is power of 2. The list is the following:
- MessageAppendix = 1
- EncryptedMessageAppendix = 2
- EncryptToSelfMessageAppendix = 4
- PrunablePlainMessageAppendix = 8
- PrunableEncryptedMessageAppendix = 16
- PublicKeyAnnouncementAppendix = 32
- PhasingAppendix = 64
The value displayed by ledger is a combination of these appendages in hexadecimal format. For instance:
- If a transaction has a PrunableEncryptedMessageAppendix and PhasingAppendix the value displayed by ledger will be 16 + 64 = 80 (0x00000050 in hex).
- If the transaction has a PrunableEncryptedMessageAppendix the value displayed by the ledger will be 16 (0x00000010 in hex) as shown in the following image:
