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):

  • 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:
