I tried again, but it do not work. I did it multiple time with Ardor v2.0.14 without any problems.

Are there way to combine manually the  "Unsigned transaction bytes" from the online machine with the "signature" obtained from the offline machine in order to  broadcastTransaction using the  transactionBytes directly in the Ardor http API instead of using the GUI?

How to get the "transactionBytes" from the ["Unsigned transaction bytes" and "signature"]. Are there simple way to get it?

I read this, but it seem outdated:
https://nxtforum.org/general-discussion/how-to-sign-a-transaction-locally-and-then-send-it-to-a-server/

"The unsigned bytes returned by the server with broadcast=false contain 64 bytes of zero in place of the signature.  Replace those bytes with the signature returned by Crypto.sign() and then broadcast the transaction using the broadcastTransaction API.  The signature bytes are at offset 95 in the transaction (see Transaction.getBytes())."

Current "signature" with Ardor seems like 128 bytes. What is the correct offset in ardor?

Overall, I think there is problem with the GUI or something else.

I need to do some transactions so I would appreciate some help if possible. Thank you.

I tried to add an encrypted message so that the  json area does not grey out. Now  I also copy the json from the online to the offline computer before signing. I used to do that with Ardor before fork and it work flawlessly, altought it was not necessary to add an encrypted message to get the json.

However, I still get this message when I want to broadcast the  signed transaction from the online computer :

Incorrect transactionJSON: null

I have some problem with offline transaction signing. It used to work, and now it not working anymore.

1) I fill the transaction I want to do  on the online machine,
2) Then I checked , do not broadcast and do not sign.

3) I  submit the transaction and new window appear where I can copy the clipboard "Unsigned Transaction Bytes". I copy the "unsigned Transaction bytes" on the offline machine by USB.

4) Then I go on the  transaction operation of the offline machine, I enter the Unsigned Transaction Bytes, I put the passphrase and sign the transaction.

5) I copy back by USB the signature on the  online machine and I broadcast the transaction from the online machine. now I get:



------
Note, last time I did it, the processus required also to copy the Unsigned Transaction JSON on the offline machine before signing, otherwise it was not working. Now the area for the Unsigned Transaction JSON is grey out on the online machine. However, it is not grey out on the transaction operation windows of the offline machine.

I don't know how to do offline signing anymore.

Thanks for looking into this.

Both machine have Ardor 2.2.2 installed.

Try to restart the browser or clean the cache, it should say something like "Switch to chain AEUR to buy IGNIS with AEUR"

The coin Exchange UI seems has a bug.When I try to exchange ARDOR on IGNIS chain,I think the words for "translation:buy_nxt_with_coin" should be "Buy IGNIS with ARDR".

I use win10,firefox,this is only happey on mainnet,and testnet is correct,so I'm little confused.

Hash: SHA512

Release 2.2.2

https://www.jelurida.com/

sha256 checksums:

4d5aa5ade0de7c4ae1ff2fc3ff75d5fdbffd6b5dc15a2673ef99db0caab12c54  ardor-client-2.2.2.zip

7be6df1d3b46e8000ae935a39969de385faac0cda1801d0fc9c6c3fad86ba88a  ardor-client-2.2.2.sh

The exe and dmg packages must have a digital signature by "Jelurida Swiss SA".


Change log:

This is a bug fix and usability enhancements release.

Users still using version 2.2.0e or earlier must upgrade immediately as they are
already on a fork, and their nodes are blacklisted by this release.

Anyone who did not upgrade to 2.2.1 prior to block 543000 must manually delete
and re-download the blockchain from scratch, after upgrading.

Users using version 2.2.1 are not required to upgrade.


Contracts:

Added an includeContract parameter to the getContractReferences API to return
metadata about the actual contract being referenced.

The contract runner now removes the last block when started to make sure
trigger transactions in the last block are processed in case processing stopped
before processing the contracts for this block.

Contract unit tests now use simpler methods for verifying transactions submitted
by a contract.

The contract manager now waits until the transactions it submitted are included
in a new block before exiting.

Contracts with an inner interface and an inner class implementing it are now
supported.

The contract processRequest callback now supports initializing a randomness
source and accessing the last block.

Fail gracefully when a contract submits the messageToEncrypt parameter without a
passphrase. Contract devs should encrypt the message first then submit the
encrypted data.


UI Enhancements:

Contract selection widget and contract parameter specification template were
added to dialogs which specify a recipient field. This enhancement simplifies
the task of configuring a contract trigger transaction.

The Contracts page now provides simple runtime statistics about contract
execution when clicking on any of the invocation types in the Invocation column.

Each chain now has a chain description displayed in the wallet and when
switching between chains.

Login by account using an Ignis alias is now supported by deleting the ARDOR
prefix then typing '@' in front of an existing alias name which is mapped to an
account id.

"Fat Finger" warning for amount and fee is now defined and enforced per chain.
Reasonable default values were defined.
Use the account settings page to adjust these values for the current chain.

Dialogs now support more than one warning per form submit.
For example in case both the amount and the fee are too high, both warnings are
displayed one after the other.

The wallet no longer warns about assets and currencies with more than 6
decimals.

The Changelly menu items was moved from a top level menu to the settings menu to
provide more screen real estate for the mobile app.

Increase and delete shares links are displayed in the "My Assets" page only when
these actions are allowed.

Vouchers with unicode parenthesis are now parsed correctly.

The desktop wallet now displays a file chooser dialog before downloading a cloud
data item or message attachment to the local workstation.

The transaction and block info dialogs now display the raw transaction and block
json in a separate tab.

Coin exchange layout improvements.


Others:

Fixed an initialization issue that could cause some custom add-ons to deadlock
on start.

Fixed false positive unsigned bytes verification error when cancelling
ARDR buy order.

The getPeers and dumpPeers APIs now also allow filtering by version, optionally
including newer versions.

Added a checkpoint at block 545555.

Updated Jetty to version 9.4.14.

My interest in crypto and gaming has been through the angle of crypto collectibles.

How would it work to take a character and all of its skills from game to game. Would each game need to be connected to the same central database / blockchain?

Cómo tokenizar un rancho, granja, explotación agraria… usando la blockchain de Ardor e Ignis
Quote
Introduction
Unfortunately, if you don't know what is your account passphrase, you cannot use your account. However in certain situations you might have a pretty good idea what your passphrase is but perhaps you made a typo while entering it or used a unicode special character without realizing it. Use this utility to attempt recovery of your real account passphrase based on approximate passphrase you remember. This utility will also find accounts without public key.

Cómo lanzar una STO (Security Token Offering), cumpliendo con la normativa KYC (Know your Customer), directamente en la blockchain de Ardor/Ignis
Quote
What does an STO need in terms of technology? It basically needs a solution to comply with the registered jurisdiction, transparency and a process to deny or accept users to be eligible to buy and trade the security token. Either an equity token, reserve asset or debt token can be launched with the following instructions (no coding needed). The steps are:
-Issue an Asset with the Ignis child chain
-Configure Asset control with by-property phasing
-Set up Account properties of your clients that passed the KYC / AML

Cómo lanzar un token de tipo único con Ardor/Ignis
Quote
The initial wave of public blockchain networks were based on the concept of immutable ledgers used to exchange fungible tokens – or rather, tokens that are uniform and can be substituted for one another. This characteristic is essential in order for money to function as money; however, a wide variety of use cases, such as those involving intellectual property, demand nonfungible tokens that are entirely unique and irreplaceable. On many existing networks, this requires coding special smart contracts. The Ignis child chain provides a template for issuing unique “singleton assets” in just 3 clicks. Continue reading to learn how to issue nonfungible tokens as singleton assets using Ignis.

Cómo lanzar en Ardor/Ignis un token equivalente a los ERC20 de Ethereum
Quote
ERC20 is a popular Ethereum standard for token management, explained here https://github.com/ethereum/EIPs/issues/20
The Ignis asset exchange on the Ardor platform already supports most of the ERC20 operations out of the box without the need to issue a smart contract.
This guide explains how to implement the ERC20 APIs using the equivalent Ardor and Ignis APIs.

¿Cómo funciona el procesamiento de las transacciones?
Quote
Calculating the balances of each Ardor account require a scan of the entire blockchain. While this might sound inefficient, with the current day network speeds and CPU speeds it is not that big of a computational task. This offloads the work required of the Ardor server and thus allows even low powered mobile devices to be a Ardor node.Calculating the balances of each Ardor account require a scan of the entire blockchain.
