X-Cash Wallet (CLI)
Use X-Cash CLI Wallet (xcash-wallet-cli) to interact with a wallet through the terminal
Overview
Command line wallet
The official command line wallet for X-Cash. Available for Linux, macOS and Windows. Download here
Wallet uses your private keys to compute your total balance, retrieve your transactions history, and sign transactions.
However, wallet does not store the blockchain and does not directly participate in the p2p network.
Depends on the full node
Wallet connects to a full node to scan the blockchain for your transaction outputs and to send your transactions out to the network. The full node can be either local (same computer) or remote.
The best practice is to run the full node on the same computer as the wallet (or within your home network) and the connection happens over HTTP.
Any transaction leaving the wallet is already blinded by all X-Cash privacy features. This means plain text HTTP communication isn't an issue on its own even if you connect to a remote node.
However, connecting to a remote node has other nuanced trade-offs, such as easiness of use and faster syncing. This happens at the cost of a potential privacy reduction and limited reliability. It is recommended to fully familiarize with the limits of using a remote node vs. a local node before attempting in doing so.
Syntax
./xcash-wallet-cli [options] [command]
Example:
./xcash-wallet-cli --restore-deterministic-wallet
Running
Go to directory where you unpacked X-Cash.
Run the daemon and wait until it syncs up with the network (may take up to a few days depending on your last block height, network speed and CPU available load):
./xcashd
In a separate terminal window, run the wallet:
./xcash-wallet-cli --generate-new-wallet XCashExampleWallet
Options
Help and version
Option
Description
--help
Enlist available options.
--version
Show xcash-wallet-cli version to stdout. Example: X-CASH '' (v1.5.0-unknown)
Pick network
(default)
By default wallet assumes mainnet.
--stagenet
Run on stagenet. Remember to run your daemon with --stagenet as well.
--testnet
Run on testnet. Remember to run your daemon with --testnet as well.
Logging
--log-file
Full path to the log file.
--log-level <arg>
0-4 with 0 being minimal logging and 4 being full tracing. Defaults to 0. These are general presets and do not directly map to severity levels. For example, even with minimal 0, you may see some most important INFOentries.
--max-log-file-size
Soft limit in bytes for the log file (=104850000 by default, which is just under 100MB). Once log file grows past that limit, x-cash creates the next log file with a UTC timestamp postfix -YYYY-MM-DD-HH-MM-SS. In production deployments, you would probably prefer to use established solutions like logrotate instead. In that case, set --max-log-file-size 0 to prevent x-cash from managing the log files.
--max-log-files
Limit on the number of log files (=50 by default). The oldest log files are removed. In production deployments, you would probably prefer to use established solutions like logrotate instead.
Full node connection
Wallet depends on a full node for all non-local operations. The following options define how to connect to xcashd:
Option
Description
--daemon-address
Use xcashd instance at <host>:<port>. Example: ./xcash-wallet-cli --daemon-address xcash-stagenet.exan.tech:38081 --stagenet
--daemon-host
Use xcashd instance at host <arg> instead of localhost.
--daemon-port
Use xcashd instance at port <arg> instead of 18281.
--daemon-login
Specify username[:password] for xcashd RPC API. It is based on HTTP Basic Auth. Mind that connections are by default un-encrypted. Authentication only makes sense if you establish a secure connection (maybe via Tor, or SSH tunneling, or reverse proxy w/ TLS).
--trusted-daemon
Enable commands and behaviors which rely on xcashd instance being trusted. Default for localhost connection. The trust in this context concerns preserving your privacy. Only use this flag if you do control xcashd. Trusted daemon allows for commands like rescan_spent, start_mining, import_key_images and behaviors like not warning about potential attack on transient problems with transaction sending.
--untrusted-daemon
Disable commands and behaviors which rely on xcashd instance being trusted. Default for a non-localhost connections. See --trusted-daemon for more details.
--do-not-relay
The newly created transaction will not be relayed to the X-Cash network. Instead it will be dumped to a file in a raw hexadecimal format. Useful if you want to push the transaction through a gateway. This may be easier to use over Tor than X-Cash wallet.
--allow-mismatched-daemon-version
Allow communicating with xcashd that uses a different RPC version.
Create new wallet
--generate-new-wallet
Create a new X-Cash wallet and save it to <arg> file. You will be asked for a password. The password is used to encrypt the wallet file but it is unrelated to your master spend key or mnemonic seed. Generate a very strong password with your password manager (~256 bits of entropy). Example: ./xcashd-wallet-cli --stagenet --generate-new-wallet $HOME/.bitxcash/stagenet/wallets/XCashExampleStagenetWallet
--kdf-rounds
Concerns encrypting the wallet file. The wallet file is encrypted with ChaCha stream cipher. The encryption key is derived from the user supplied password by hashing the password with CryptoNight. This option defines how many times the CryptoNight hashing will be applied. The default is 1 round of hashing. Note this is unrelated to spend key generation. The more rounds the longer you will wait to open the wallet or send transaction. But also the attacker will have it harder to brute force your wallet password. Note: You will have to remember and provide the same kdf-rounds on every wallet access! Recommendation: Do not change the default value. Instead generate a very strong wallet password with your password manager (256 bits of entropy).
Open existing wallet
Option
Description
--wallet-file
Open existing wallet. Example: ./xcash-wallet-cli --stagenet --wallet-file $HOME/.bitxc/stagenet/wallets/XCashExampleStagenetWallet This is only for wallet files generated with xcash-wallet-cli, xcash-wallet-gui, or xcash-wallet-rpc tools. If you have other type of wallet then see importing options.
--password
Provide wallet password as a parameter instead of interactively. Remember to escape/quote as needed. Not recommended because the password will remain in your command history and will also be visible in the process table. For automation prefer --password-file. The option also works in combination with --generate-new-wallet.
--password-file
Provide password as a file in stead of interactively. Trailing are discarded when reading the password file. Prefer this over --password if you automate wallet access. Make sure the password file is meaningfully separated from the wallet file. Otherwise it provides no security benefit. The option also works in combination with --generate-new-wallet.
Restore wallet
Option
Description
--generate-from-device
Restore/generate a special wallet to work with a hardware device like Ledger or Trezor and save it to <arg> file. Example: ./xcash-wallet-cli --stagenet --generate-from-device XCashExampleDeviceWallet --subaddress-lookahead 5:20 This is a one-time action. Next time you simply open the wallet. By default the command expects Ledger hardware connected. For Trezor hardware add --hw-device Trezor (expected ~May 2019). It will take up to 25 minutes with default settings. This is because hardware devices are slow to pre-generate subaddresses. To mitigate use low --subaddress-lookahead 5:20. The local wallet will not have private spend key and will not be able to spend on its own. It serves as a user interface and a bridge for low-power hardware devices. Transaction signing with a private spend key always happens on the hardware device. See the complete guide to hardware wallet setup.
--generate-from-view-key
Restore a view-only version of the wallet to track incoming transactions and save it to <arg> file. The wallet is created based on a secret view key and standard address. The secret view key is meant to be pasted as hexadecimal.
--generate-from-spend-key
Restore a wallet from secret spend key and save it to <arg> file. The secret spend key is meant to be pasted as hexadecimal.
--restore-deterministic-wallet
Restore a wallet from secret mnemonic seed. Use this to restore from your 25 words backup. You will be asked for a password to encrypt the wallet file (once restored). Note this is not a passphrase to mnemonic seed. Mnemonic seeds generated by X-Cash official wallets are naked.
Multisig wallet
Option
Description
--generate-from-multisig-keys
Create a standard wallet from multisig keys. This is useful to combine all multisig secret keys back into the standard wallet (when you no longer need the multisig). The wallet will then have control of the funds. It only supports providing all secret keys even if the multisig scheme allowed for less (only N/N not N/M).
--restore-multisig-wallet
Restore a multisig wallet from secret seed that was earlier exported with the seed interactive command. This only restores your part of the wallet. Other multisig participants will still be necessary to sign the transaction.
Config file
Option
Description
--config-file
Full path to the configuration file. Note this should be a separate config than xcashduses because these tools accept different set of options.
Performance
Option
Description
--subaddress-lookahead
Accepts m:n, by default 50:200. The first value is the number of accounts and the second value is the number of subaddresses per account. The wallet will not check for payments to subaddresses further than naway from the last received payment. This can happen if you generated unique subaddresses for n clients in a row but none of them paid. On the other hand the more subaddresses you set to look ahead, the longer it takes to create your wallet, because they must be pre-computed. This is normally not a concern, except for hardware wallets. On the Ledger the default value of 50:200 can take over 20 minutes (one time on wallet creation)!
--max-concurrency
Max number of threads to use for parallel jobs. The default value 0 uses the number of CPU threads
Internationalization
Option
Description
--mnemonic-language
Language for mnemonic seed words. One of english, english_old, esperanto, french, german, italian, japanese, lojban, portuguese, russian, spanish. It might be a good idea to stick to default English which is by far the most popular and well tested. It also avoids potential non-ASCII characters pitfalls or bugs.
--use-english-language-names
If your display freezes, exit blind with ^C, then run again with --use-english-language-names. This can happen when X-Cash prompts for a language displaying language names in their natives alphabets.
Legacy
Option
Description
--non-deterministic
Generate legacy non-deterministic wallet. The view key will not be derived from the spend key. You would also have to backup the .keys. To restore non-deterministic wallet (standard address) use --generate-from-keys. To restore fully you will need the .keys file.
--generate-from-keys
Restore legacy non-deterministic wallet by providing both spend and view keys and the standard address.
--shared-ringdb-dir
Set shared ring database path. No longer worthwhile.
--electrum-seed
Provide mnemonic seed as a command line option for --restore-deterministic-wallet instead of interactively. This is not recommended b/c the seed will be saved in your command history and also visible in the process list.
--generate-from-json
You would run xcash-wallet-rpc to use this option.
--tx-notify
You would run xcash-wallet-rpc to use this option.
Default setup
Wallet files are created and seek in current directory. This is rarely what you want. Use --wallet-file and similar options to control this.
Log files are created in the same directory as xcash-wallet-cli binary. Use --log-file to specify the location.
Commands
Commands are used interactively in the xcash-wallet-cli prompt.
You can also run a one-off command by providing it as a commandline parameter. This is rarely useful though. For automation prefer xcash-wallet-rpc.
The CLI wallet has built-in help for individual commands - we will not attempt to reproduce that. Instead we focus on grouping commands so you can quickly find what you are looking for. Use help command_name to learn more.
Help and version
help - list all commands
help <command> - show help for individual command
version - show version of the xcash-wallet-cli binary
Balance
account - total balance; list accounts with respective balances
balance detail - within the current account, list addresses with respective balances
Transfer funds
To perform on-chain transaction you should used the function transfer:transfer [<tx_privacy_settings>] [index=<N1>[,<N2>,...]] [<priority>] [<ring_size>] <address> <amount> [<payment_id>]
Option
Description
tx_privacy_settings
Blockchain privacy setting feature, can be public or private. Defaults to private.
index
Index of the transaction.
priority
Priority setting i.e. fee (multiplier) settings, can be [0, 1, 2, 3, 4]
Defaults to 1.
Leads to a multiplication of the base fee per kb of respectively 1x, 4x, 20x, and 166x.
ring_size
Number of possible signers in the ring signature. Defaults and fixed to 21since 1.4.0
address
Recipient address. Should be an XCASH, integrated or subaddress.
amount
Amount to be sent in XCASH.
payment_id
Payment id to be added to the transaction. Defaults to none.
You can also move the entire balance by using the sweep_all command with the same parameters (except the amount) as the transfer command. If you leave sweep_all blank with no parameters it will send a tx back to your wallet. This is helpful in reducing unspents for voting.
Vote for a delegate
Open the wallet file in the xcash-wallet-cli and once the wallet is fully synchronize, type the command:
vote <delegates_public_ip|delegates_name>Replace
delegates_public_address|delegates_namewith thedelegates public addressordelegates name
Manage accounts
account
account new
account switch
account label
Manage addresses
address all
address new
address label
Network status
status - show if synced up to the blockchain height
fee - show current fee-per-byte and full node's mempool (the backlog of transactions depending on the priority)
wallet_info - show wallet file path, standard address, type and network
Secret mnemonic seed
seed - show raw mnemonic seed
encrypted_seed - create mnemonic seed encrypted with the passphrase; you will need to remember or store the passphrase separately; restoring will not be possible without the passphrase
Secret keys
spendkey - show secret spend key and public spend key
viewkey - show secret view key and public view key
Proofs
get_reserve_proof -> check_reserve_proof - prove the balance
get_spend_proof -> check_spend_proof - prove you made the payment
sign <file> -> verify <filename> <address> <signature> - prove ownership of the address; allows to verify the file was signed by the owner of specific X-Cash address
get_tx_proof -> check_tx_proof
Multisig
Setup
prepare_multisig
make_multisig
finalize_multisig
Update
export_multisig_info
import_multisig_info
Other
submit_multisig
exchange_multisig_keys
export_raw_multisig_tx
Tx private key
These allow to learn and verify transaction's private key r. This was useful to create a proof of payment but got superseded by get_spend_proof.
get_tx_key <txid>
check_tx_key <txid> <txkey> <address>
set_tx_key <txid> <tx_key>
Advanced
unspent_outputs - show a list of, and a histogram of unspent outputs (indivisible pieces of your total balance)
export_key_images <file> -> import_key_images <file> - used to inform the view-only wallet about outgoing transactions so it can calculate the real balance; normally view-only wallets only learn about incoming transactions, not outgoing
export_outputs <file> - export a set of outputs owned by this wallet to a <file>
