on C: import the file, sent it to network

when I use command

"cardano-cli transaction add-input 25Ab2p01affa1bc8f35efeb7eea54e2ac1113f80d8628502c0f5a87f3295634f6df53f 2 "

01affa1bc8f35efeb7eea54e2ac1113f80d8628502c0f5a87f3295634f6df53f 2 is one address's utxo but not exist in I machine.

Errror:Cannot find inputs within the local UTxOs

so it is mean when create a transaction. input addr must in local machine ????

I just want use one addr utxo then create transaction. then send transaction to another machine which not connect internet to sign it .

Hi guys

I try to issue these commands

cardano-cli blockchain pull mainnet

and then I sync my wallet to the blockchain

cardano-cli wallet sync "My Wallet"

but it seems its not writing the updates to the wallet data file

its always stuck to the first point when i attached the wallet

but this is fixed when i detach / attach but then i get the error again, so it takes a very long time to get updates to the wallet by doing "detach/attach"

but maybe I'm doing something wrong.

OS: Windows Sub-System for Linux, Ubuntu 18

Thank you!

Hi All, Crazy as it may sound - I generate my private keys on the Ethereum block chain by flipping a coin.

This way even if someone were to place malware into my client which will produce a predictable private key my funds can not be stolen by this attack.

Before I can seriously invest in Cardano, I must be able to use my own private key which has been produced by some manner that is known to be truly random and unhackable.

Is it possible using the Cardano-CLI to create a wallet from a private key which has been generated by some offline method such as flipping a coin?

Thanks, John

Using Web3 for Ethereum at the command line it is possible to create and send offline transactions from an airgapped computer without syncing to the blockchain.

This video shows how to create the offline transaction on an airgapped device using the CLI:

This video shows how to send the offline transaction to the blockchain without needing to sync up or even have a copy of the blockchain.

This video shows an airgapped device created for making offline transactions.

I need this level of security before I can seriously invest in Cardano. Can I create and send offline transactions from an airgapped device using the Cardano-CLI? Thanks, John

We have two quick questions regarding the implementation, can you please help us take a look?

1. When creating wallet via cardano-cli, how do you set mnemonic words? And if will the wallet be able to be recovered from another device which has cardano-cli installed?

2. What is the maximum number of addresses allowed in each wallet under the cardano-cli?

3. We did a test in which we have sent a certain amount of ADAs to two different addresses in one wallet under the cardano-cli, but only to see UTXO shown in one of the addresses after executing cardano-cli wallet utxos.

Thanks for your help!

Following is the original ticket sent to iohk

Here's the list of questions:

Can the address be generated offline? Can we pull out the private key once generated offline?

Will the transaction be generated offline and broadcasted through the node after being signed with the private key?

Do you support JSON-RPC type of request like Ethereum does?

If we use cardano-cli as a black-box program to support ADA, how do we ensure that the value of “actual fee” is larger than that of “fee”? Because the fee and tx-bytes will only show after input and output being filled.

Can the private key of the address be exported using cardano-cli?

Can we pull out the original transaction hash that has been signed (before being broadcasted) using cardano-cli?

Can the cardano-cli be used as a node, for the purpose of like searching for transactions and checking balances. Do you have an API for it?

How do other exchanges support ADA, is it via cardano-cli or cardano-sl?

How do other exchanges confirm transactions? Is it by using lowest assurance, medium assurance or high assurance?

Can the private key be exported from cardano-sl’s wallet address?

Can we pull out the original transaction hash that has been signed (before being broadcasted) using cardano-sl?

While using the API from cardano-api package, what does “cbeBlockLead” and “cbsMerkleRoot” mean in the block details section?

While using the API from cardano-api package, what does “ctsRelayedBy” mean in the transaction details section?

How long does it normally take to produce a block? Is it around 20 seconds? The 20 seconds result is a calculation based on the comparison between different values of “ctbTimeIssued” from cardano-api since it’s not shown in the explorer.

This issue puts the wallet into a bad state. Once in this bad state the wallet will report the below error for many functions:

./target/debug/cardano-cli wallet status my_magic_wallet

The bad state is that the last UTxO is stored twice in the LOG file. The bad state comes about by performing a second sync operation on the wallet. To recreate, recover a wallet that has a UTxO, sync the wallet (you can see the state is correct by doing strings LOG which will show the UTxO), then sync again (again strings LOG will show the last UTxO is now stored twice).

It looks like the second sync, instead of starting where the last sync finished (81.13276) instead starts from the block time of the last UTxO in the log (81.11021), I am guessing this causes that UTxO to be picked up again, or maybe it is something about the reading/writing of the LOG. Not sure.

Wrong success message after using wallet detach.

• cardano-cli wallet detach "wallet-name" Message: Wallet successfully attached to blockchain.

Hello. I wanted to play a little with cardano-cli on both macOS and windows 10. (I pulled the master branch approx 10 days ago) I am commenting this issue because I managed after syncing several times a wallet to generate a DOUBLE UTXO CREDIT which gives me a wrong final balance. Indeed if i detach and attach the wallet to the blockchain and finally resync the wallet last utxo credit is not duplicated in the log. Contrarily to @HM999 I did not have any kind of fatal errors But it's quite annoying having to make [detach, attach and syncing] operations again to be in a "correct" state.

What would you suggest? Thanks

External

As a pool operator dealing with funds/staking keys of (non-technical) pool owners is too complicated. Pool owners (pledging) should not need the cardano-cli to monitor and manage their funds.

We can create mnemonics using cardano-address, as well as keys and addresses. Keys can be base16.

cardano-cli only understands key files in cborHex.

Feature request

Either have

cardano-cli understand raw base16 keys

or

expose a conversion command in cardano-cli, that simply takes the base16 key generated using cardano-address and converts it to a cborHex skey/vkey file readable by cardano-cli.

As far as I understand it, we could then restore a wallet in Daedalus using the mnemonics, monitor/manage funds, if necessary, but still have generated the necessary payment and staking keys using cardano-address/cli.

This is potential useful for all pool operators/owners.
