Hydra Core Wallet Commands

The Hydra Core wallet has a rich set of commands which give comprehensive control of the wallet and blockchain transactions. There are two sets of commands that may be used with Hydra Core wallets:
Console commands are given to a wallet that is already running.
Startup commands are used when starting up a wallet.
This manual focuses on the console commands which are given to a wallet that is running and can be sent using RPC (Remote Procedure Calls) or on the command line to the hydrad server wallet or given to the Hydra-qt desktop GUI (Graphical User Interface) wallet using the Debug window Console command line (see Figure 1).
​ Figure 1. The hydra-qt Console
Note the warning message in red in Figure 1 and be careful using the private key commands (dumpprivkey and dumpwallet) with Mainnet wallets.
For the server wallet hydrad, console commands are given using the Command Line Interface application hydra-cli on the system command line prompt (see Figure 2).
You can always get a list of the current console commands using the help command (see Figure 3.)

Console Commands :hammer_and_wrench:
Console commands are given to a running Hydra Core wallet and provide additional information and control. Console commands and are required to operate the hydrad server wallet, which is a "headless" wallet with no graphical user interface.
There are 136 console commands with some good references for the 112 inherited from bitcoin. There are 13 "hidden" commands that are used by developers and won't show up in the "help" list.
Commands can have required or optional parameters and more numerous parameters are entered in JSON (JavaScript Object Notation) format with escaped double quotes ( \" ) as shown below.
Common parameters for these commands are Hydra addresses, block hashes, contract addresses, etc. Some of the commands will have an optional parameter "minconf" (minimum confirmations) which allows you to get a response for a transaction or block that has at least that number of confirmations.
The chain query bitcoin API reference http://chainquery.com/bitcoin-api explains the parameters and gives examples with responses for the commands inherited from bitcoin. The bitcoin chain query API reverence gives 67 commands, of which 2 are not in Hydra (estimatepriority, getgenerate) and two (gettransaction, walletpassphrase) have an additional parameter for Hydra. See also https://bitcoin.org/en/developer-reference#remote-procedure-calls-rpcs.
Advanced interfaces to the Hydra Core wallet (full node) can use these "console commands" as RPCs (Remote Procedure Calls) over a dedicated port connection to the node. To build an exchange hot wallet or server node for a mobile DAPP (Distributed Application) you can use RPCs, which follow these same console commands. The client node offers a JSON-RPC interface over HTTP sockets to perform various operational functions and to manage the local node.
A quick comment on "accounts". Accounts was an ill-fated way from bitcoin to track balances for what are really UTXO transaction-based values, and "accounts" are deprecated and will be phased out by version 0.18.
Here are some command groupings that are useful for various tasks:
Peer connections: getconnectioncount, getpeerinfo, addnodes, getnetworkinfo
Staking: getstakinginfo, getwalletinfo, getnetworkinfo
Sending: listaddressgroupings, sendtoaddress, sendmany, sendmanywithdupes
Raw transactions: crearterawtransaction, signrawtransaction, combinerawtransactoins, sendrawtransaction
Smart contract transactions: createcontract, callcontract, sendtocontract, getaccountinfo, getstorage, searchlogs, waitforlogs
Startup Commands
Startup commands give additional control and recovery options when launching the wallet. For example, you can use startup commands for various kinds of blockchain recovery techniques, additional debug logging or additional controls. If you are going to use these startup commands, make sure you have a good backup of the wallet.dat file.
See the startup commands on the Hydra-qt wallet with Help - Command line options:
​ Figure 4. Startup commands
and on the command line itself with "Hydra -?":
​ Figure 5. Startup commands from the command line
Console Commands A - Z
For these console commands documented below, responses are given for default parameters (Hydraversion 0.16 - winter 2018/2019). Commands marked DEPRECATED should not be used because they will be removed and replaced in future versions of the wallet, for example, commands using "account" will be removed in version 0.18.
Using the command "help \" will give complete information about the command and relevant parameters, formatted in a way you can copy and paste (replacing the addresses, transactions IDs, etc., as required). The format below shows the command with parameters followed by the response, in some cases, parameters or responses are truncated with the term "\". Where noted, some commands only work with the regtest (Regression Test) network. Many commands will return "null" for Hydra-qt and return nothing for command line systems.
abandontransaction "txid"
Works on transactions not in the blockchain or mempool, used in testing.
abandontransaction "0cc99a30bc2064041ea4263835b4ed594ff500c56d6b14e4970aeee548e71389"
​
Transaction not eligible for abandonment (code -5)
abortrescan
Stops a wallet rescan triggered by a command such as importprivkey. This command can be issued by opening a 2nd command line window (where the first window is scanning), in which case the command will stop the scan and return "true".
hydra-cli abortrescan
​
true
addmultisigaddress nrequired ["key",...] ( "account" "address_type" )
Add a multisignature address to the wallet so you can receive and send from that address. Run the command on each machine that will be signing and backup the wallet.dat file. The address can be a Hydra address or hex-encoded public key. Use importaddress to add the multisig address on each signing wallet.
This functionality is only intended for use with non-watchonly addresses. See importaddress for watchonly p2sh address support. Use of account is DEPRECATED). See also validateaddress.
addmultisigaddress 2 "[\"HgdaD9b3ppKowoC45EZMtepjjBfnvEe6m\",\"HFmr8vY29reHj73XSHfdWvkV3mD57Kqd8\"]"

}
addnode "node" "add|remove|onetry"
Attempts to add a node with a known IP address. This command is useful for new wallets that are having trouble making peer connections. Here are some good IP addresses to add, you can put these commands in one after another, then the wallet will try for a few minutes to make a peer connection with each. Hydrad returns nothing:
addnode 35.200.159.68:3888 add
addnode 35.197.138.163:3888 add
addnode 35.226.31.206:3888 add
addnode 35.200.130.53:3888 add
addnode 35.192.54.161:3888 add
Hydra-qt returns "null" after each (see Figure 6).
​ Figure 6. Entering the addnode command
addwitnessaddress "address" ( p2sh )
Hidden command. DEPRECATED. This command was a way to generate a SegWit address from an existing legacy address, usually a P2SH-P2WPKH addresses - Pay-to-Witness-Public-Key-Hash (P2WPKH) script embedded in a Pay-to-Script-Hash (P2SH) address. This command is mostly disabled in version 0.16 and will be removed in version 0.17. Instead, use the getnewaddress command with address type "p2sh-segwit" or "bech32".
Launch v 0.16 Hydrad with -deprecatedrpc=addwitnessaddress to run the command:
addwitnessaddress HkSc3wcAJ59Nk4X9mvd258ycVxJ7XWhp9
​

}
createmultisig nrequired ["key",...]
DEPRECATED. Use addmultisigaddress.
createrawtransaction [{"txid":"id","vout":n},...] {"address":amount,"data":"hex",...} ( locktime ) ( replaceable )
Create a hex-encoded raw transaction sending some inputs to outputs. The transaction must then be signed and sent to the network, see signrawtransaction and sendrawtransaction. Returns a hex-encoded raw transaction. If you are sending coins make sure to create a change address so the change can be returned; any difference between the input values and output values will be taken as the transaction fee. If you don't work out the math you could pay a big transaction fee.
createrawtransaction "[{\"txid\":\"17b3f9ef530695ef2e0368e445a3b59bf12811bdfd42325bb14248e72deb7e2\",\"vout\":0}]" "{\"Qd5eHho389mJMCxSzAbe31w2vntTc7192\":1.0, \"QdXtq55Bf443Lkme2hdj4mD8KKepk32f6\":0.99}"

dumpwallet "filename"
Writes all the wallet private keys to a file in clear text (unencrypted) format. The wallet must be fully decrypted (not just for staking only) for this command to work. Returns the filename. Dumpwallet will save all the private keys and their addresses; it will not save watchonly addresses (which do not have private keys in the wallet). This file contains all the private keys in the wallet (1,000 or more), be very careful and do not store the dump file online.

encryptwallet [passphrase]
Encrypts the wallet with "passphrase" for first-time encryption. After encryption, any calls that interact with private keys such as sending or signing will require passphrase entry to enable these functions. See also walletpassphrase, walletlock and walletpassphrasechange. After this command runs, the wallet will shut down.
encryptwallet [you should always use a long and strong passphrase]
(wallet exits)
echo "message"
Hidden command. Simply echo back the input arguments. This command is for testing.
The difference between echo and echojson is that echojson has argument conversion enabled in the client-side table in Hydra-cli and the GUI. There is no server-side difference. Here we echo the parameters used to setup a multisig address.

estimatefee is deprecated and will be fully removed in v0.17.
estimaterawfee conf_target (threshold)
Hidden command. WARNING: This command is unstable and may disappear or change, and the results are tightly coupled to the calling parameters.
Gives fee estimates for short, medium, and long term confirmations, and gives mempool statistics for transactions with those fees. Estimates the approximate fee per kilobyte needed for a transaction to begin confirmation within conf_target blocks.

fundrawtransaction "hexstring" ( options iswitness )
Select and add inputs to a transaction until it has enough in value to meet its out value. Collects one or more unspent transactions as inputs, and computes and specifies the change amount. Note that inputs which were signed may need to be resigned after completion since in/outputs have been added. The inputs added will not be signed, use signrawtransaction for that.

importaddress "address" ( "label" rescan p2sh )
Adds a 34-character Hydra address or 66 hex character public key address that can be watched as if it were in your wallet but cannot be used to spend. The wallet will rescan after entering this command and should be backed up after adding addresses. Hydra-qt returns "null" and displays the "Watch-only" balance, Hydrad returns nothing.

importmulti "requests" ( "options" )
Import multiple addresses/scripts (with private or public keys, redeem script (P2SH)), rescanning the blockchain for all the new addresses in a single pass. Optional time stamps can control how far back the scanning begins for each address. Requires a new wallet backup after addition of the addresses.
Here we import two watch only addresses and scan the blockchain from 00:00:00 hours GMT on June 1, 2018 (timestamp 1527811200). After entering the command, the wallet will take several minutes to rescan the blockchain for the new addresses:
importmulti '[{ "scriptPubKey": { "address": "HX4kcv3ZWZpax2tb44tpiv7q3wEB8Sek5" }, "timestamp":1527811200 }, { "scriptPubKey": { "address": "QN3BkewbR37fQs226ZA2qkh83mKS529B" }, "timestamp": 1527811200 }]'

importprivkey "hydraprivkey" ( "label" ) ( rescan )
Adds a WIF private key to your wallet, for example as returned by dumpprivkey or from another Hydra wallet. The wallet must be unlocked and requires a new wallet backup afterwards. The wallet will rescan for a few minutes to add any balance from the new address, and return "null" if successful.

importprunedfunds
Imports funds without rescan. Corresponding address or script must previously be included in wallet. Aimed towards pruned wallets. The end-user is responsible to import additional transactions that subsequently spend the imported outputs or rescan after the point in the blockchain the transaction is included.
Example TO COME.
importpubkey "pubkey" ( "label" rescan )
Adds a public key that can be watched as if it were in your wallet but cannot be used to spend. The public key is 66 characters hex, and can be obtained using the validateaddress command. After entering this command, the wallet will rescan for a few minutes, Hydra-qt returns "null" and hydrad returns nothing. The wallet should be backed up after importing a public key.

​
null
importwallet "filename"
Imports keys from a wallet dump file (see dumpwallet). Requires a new wallet backup after this command. Use the full path to the dump file. Hydra-qt will show a status of "Importing" for a while, then "Scanning" as it rescans the blockchain. This command may take five minutes or more to return, and the wallet may appear to freeze during this time.
On a PC with the dump file in a folder "Backups" on the Desktop:
importwallet "C:\Users\\Desktop\Backups\dump 2019-01-14.txt"
​
null
invalidateblock "blockhash"
Hidden command. Permanently marks a block as invalid, as if it violated a consensus rule. Used for software testing or in some rare manual blockchain forking scenarios. Use reconsiderblock to reverse this command. Returns "null" if successful.

​
null
keypoolrefill ( newsize )
Refills the key pool with new private keys, with a default size of 100. The normal size of the keypool is 1,000 and the wallet opportunistically fills the keypool as addresses are used, so this command should use a 1,100 size, etc., to be meaningful. The wallet must be unlocked. Hydra-qt returns "null", Hydrad returns nothing.

​
null
listaccounts ( minconf include_watchonly)
DEPRECATED. Returns information about account names and account balances. Gives the balance in Satoshis (Hydra x 0.00000001), including the default undefined account.
This "account" was an attempt to manually track balances from bitcoin which will be removed by version 0.17, because it doesn't work well, for example, returning negative values:

lockunspent unlock ([{"txid":"txid","vout":n},...])
Updates list of temporarily unspendable outputs. Temporarily lock (unlock=false as shown below) or unlock (unlock=true) the specified transaction outputs. If no transactions are specified when unlocking then all current locked transactions are unlocked.
A locked transaction output will not be chosen by automatic coin selection when spending Hydra.
Locks are stored in memory only. Wallets launch with zero locked outputs and the locked output list is always cleared (by virtue of process exit) when a wallet stops or fails. Also see the listunspent call.
lockunspent false "[{\"txid\":\"9fc384b55230ca1899dd1acf081033ebf57ae0335abf692c4f8a6336befc2f6\",\"vout\":1}]"
​
true
logging ( )
Gets and sets the logging configuration for the debug.log file. When called without an argument, returns the list of categories with status that are currently being debug logged or not. When called with arguments, adds or removes categories from debug logging. The arguments are evaluated in order "include" then "exclude". If an item is both included and excluded, it will thus end up being excluded.
The valid logging categories are: net, tor, mempool, http, bench, zmq, db, rpc, estimatefee, addrman, selectcoins, reindex, cmpctblock, rand, prune, proxy, mempoolrej, libevent, coindb, qt, leveldb, coinstake, and http-poll.
Here we turn on logging for "mempool" and "mempoolrej" (they are listed first for "include") and turn off "http". Returns the current debug logging status.
logging "[\"mempool\", \"mempoolrej\"]" "[\"http\"]"

ping
Requests that a ping be sent to other peers, to measure ping time. Results are provided in getpeerinfo, "pingtime" and "pingwait" fields are decimal seconds (does not provide a direct result like using "ping" from a system command prompt). The ping command is handled in queue with all other commands, so it measures processing backlog, not just network ping.

null
preciousblock "blockhash"
Prioritizes a block with an earlier time for blocks at the same height. Used in hard fork situations. See also invalidateblock. Hydra-qt returns "null" if successful, Hydrad returns nothing if successful.

null
prioritisetransaction
Accepts the transaction into mined blocks at a higher (or lower) priority. A higher fee is not actually paid, the algorithm for selecting transactions into a block (which is trying to maximize fees) considers the transaction as having paid a higher fee. Hydra-qt and Hydrad return "true":
prioritisetransaction "01b347eb32bca5cde81444f6a6d4311f02ae3f3da25394e0f144fca525218dd" 0.0 10000
​
true
pruneblockchain
Prune the blockchain up to a given block. Pruning removes spent transactions to reduce the storage size for the blockchain. Returns the last block pruned. The wallet must be launched in prune mode with disk working space reserved, at least 550 MB, here with 2 GB of working space:
Hydra-qt.exe -prune=2000
Then you can give the command
pruneblockchain 125000
​
125000
Don't prune the blockchain if your wallet accepts incoming connections (over 8 peers) because your wallet needs to be able to send all the blocks to bootstrap new peers coming online.
reconsiderblock "blockhash"
Hidden command. Removes invalidity status of a block and its descendants, used for code testing or in manual blockchain reorganization. This command can reverse the effects of invalidateblock. Returns "null" if successful:

​
null
rescanblockchain ("start_height") ("stop_height")
Rescan the local blockchain for wallet transactions. An optional start height and stop height can be used, or by default scan the entire blockchain. This command will scan the blockchain for transactions of your wallet, and can be used if the wallet balance doesn't appear to be correct after a wallet restore or adding private keys. Returns the start and top height scanned.
rescanblockchain 100000 200000
​
{
  "start_height": 100000,
  "stop_height": 200000

resendwallettransactions
Hidden command. Immediately re-broadcast unconfirmed wallet transactions to all peers. The wallet periodically re-broadcasts automatically, so this can be used for testing. Here two transactions were resent after being stuck in the local mempool after restarting the wallet.

waitforlogs (fromBlock) (toBlock) (filter) (minconf)
requires -logevents to be enabled
Waits for a new logs and returns matching log entries. When the call returns, it also specifies the next block number to start waiting for new logs. By calling waitforlogs repeatedly using the returned nextBlock number, a client can receive a stream of up-to-date log entries.
This call is different from the similarly named searchlogs. This call returns individual matching log entries, searchlogs returns a transaction receipt if one of the log entries of that transaction matches the filter conditions.
Arguments:
fromBlock (int | "latest", optional, default=null) The block number to start looking for logs. ()
toBlock (int | "latest", optional, default=null) The block number to stop looking for logs. If null, will wait indefinitely into the future.
filter ({ addresses?: Hex160String[], topics?: Hex256String[] }, optional default={}) Filter conditions for logs. Addresses and topics are specified as array of hexadecimal strings
minconf (uint, optional, default=6) Minimal number of confirmations before a log is returned
Example TO COME.
waitfornewblock (timeout)
Hidden command. Waits for a new block and returns the blockhash and height. Returns the current block on timeout or exit. This command works on command line only (not with the Hydra-qt GUI wallet) and is used for development. The timeout parameter is given in milliseconds and 0 indicates no timeout.
On Docker with regtest:
waitfornewblock
​
{
  "hash": "47f1ddc856ba47a242cbdc771d198296f3a1343f81aad21d454bec438972868c",
  "height": 7207
}
On Mainnet with Hydrad:
Hydra-cli waitfornewblock
​
{
  "hash": "b4caac261c4f5386076bbb07e0dc94b92fb67ca740b8a5d7b49cddcaffd6f103",
  "height": 281981
}
walletlock
Locks an encrypted wallet.
walletlock
​
null
Hydra-cli returns no response, but you can check with getwalletinfo for "unlocked_until": 0 and check the padlock icon on Hydra-qt.
walletpassphrase [passphrase] timeout ( true )
Unlock an encrypted wallet for transactions which require use of a private key, such as sending coins, staking, or exporting private keys. Timeout gives the time in seconds to unlock and the optional Boolean "true" allows unlocking for staking only.
This command would unlock the wallet for 10 minutes:
walletpassphrase [you should always use a long and strong passphrase] 600
This command would unlock the wallet for staking only for a long time:
walletpassphrase [you should always use a long and strong passphrase] 99999999 true
The Hydra-qt wallet will show lock status with the padlock icon and the Console returns "null". Hydra-cli returns no status but you can check the unlock status with getwalletinfo for "unlocked_until":
walletpassphrasechange [oldpassphrase] [newpassphrase]
Changes the wallet passphrase from [oldpassphrase] to [newpassphrase], Hydra-qt returns "null", Hydrad returns nothing.
walletpassphrasechange [you should always use a long and strong passphrase] [please use a strong and long passphrase]
