gettxoutproof

Returns a hex-encoded proof that "txid" was included in a block.

NOTE: By default this function only works sometimes. This is when there is an unspent output in the utxo for this transaction. To make it always work, you need to maintain a transaction index, using the -txindex command line option or specify the block in which the transaction is included manually (by blockhash).

Arguments:

1. "txids" (string,required) A json array of txids to filter
[
"txid" (string) A transaction hash
,...

waitforlogs

waitforlogs (fromBlock) (toBlock) (filter) (minconf) requires -logevents to be enabled

Waits for a new logs and return 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 entires.

This call is different from the similarly named waitforlogs. 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:

1. fromBlock (int | "latest", optional, default=null) The block number to start looking for logs. ()
2. toBlock (int | "latest", optional, default=null) The block number to stop looking for logs. If null, will wait indefinitely into the future.
3. filter ({ addresses?: Hex160String[], topics?: Hex256String[] }, optional default={}) Filter conditions for logs. Addresses and topics are specified as array of hexadecimal strings
4. minconf (uint, optional, default=6) Minimal number of confirmations before a log is returned

Result:

An object with the following properties:
1. logs (LogEntry[]) Array of matchiing log entries. This may be empty if `filter` removed all entries.2. count (int) How many log entries are returned.3. nextBlock (int) To wait for new log entries haven't seen before, use this number as `fromBlock`
Usage:
`waitforlogs` waits for new logs, starting from the tip of the chain.
`waitforlogs 600` waits for new logs, but starting from block 600. If there are logs available, this call will return immediately.
`waitforlogs 600 700` waits for new logs, but only up to 700th block
`waitforlogs null null` this is equivalent to `waitforlogs`, using default parameter values
`waitforlogs null null` { "addresses": [ "ff0011..." ], "topics": [ "c0fefe"] }` waits for logs in the future matching the specified conditions

Sample Output:

Control

echo

echo|echojson "message" ...

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.

getmemoryinfo

Returns an object containing information about memory usage.

Arguments:

1. "mode" determines what kind of information is returned. This argument is optional, the default mode is "stats".

prioritisetransaction

Accepts the transaction into mined blocks at a higher (or lower) priority

Arguments:

1. "txid" (string, required) The transaction id.
2. dummy (numeric, optional) API-Compatibility for previous API. Must be zero or null.
DEPRECATED. For forward compatibility use named arguments and omit this parameter.

considers the transaction as it would have paid a higher (or lower) fee.

Result:

true (boolean) Returns true

Examples:

> hydra-cli prioritisetransaction "txid" 0.0 10000

### finalizepsbt

Finalize the inputs of a PSBT. If the transaction is fully signed, it will produce a network serialized transaction which can be broadcast with sendrawtransaction. Otherwise a PSBT will be created which has the final_scriptSig and final_scriptWitness fields filled for inputs that are complete. Implements the Finalizer and Extractor roles.

Arguments:

1. "psbt" (string) A base64 string of a PSBT
2. "extract" (boolean, optional, default=true) If true and the transaction is complete, extract and return the complete transaction in normal network serialization instead of the PSBT.

Result:

{
"psbt" : "value", (string) The base64-encoded partially signed transaction if not extracted
"hex" : "value", (string) The hex-encoded network transaction if extracted
"complete" : true|false, (boolean) If the transaction has a complete set of signatures
}

Examples:

> hydra-cli finalizepsbt "psbt"

fromhexaddress

Converts a raw hex address to a base58 pubkeyhash address

Arguments:

1. "hexaddress" (string, required) The raw hex address

Result:

"address" (string) The base58 pubkeyhash address

Examples:

> hydra-cli fromhexaddress "hexaddress"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "fromhexaddress", "params": ["hexaddress"] }' -H 'content-type: text/plain;' http://127.0.0.1:3889/

Test example:

fromhexaddress "6c89a1a6ca2ae7c00b248bb2832d6f480f27da68"

Test result:

fundrawtransaction

Add inputs to a transaction until it has enough in value to meet its out value. This will not modify existing inputs, and will add at most one change output to the outputs. No existing outputs will be modified unless "subtractFeeFromOutputs" is specified. 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. Note that all existing inputs must have their previous output transaction be in the wallet. Note that all inputs selected must be of standard form and P2SH scripts must be in the wallet using importaddress or addmultisigaddress (to calculate fees). You can see whether this is the case by checking the "solvable" field in the listunspent output. Only pay-to-pubkey, multisig, and P2SH versions thereof are currently supported for watch-only

Arguments:

1. "hexstring" (string, required) The hex string of the raw transaction
2. options (object, optional)
{
"changeAddress" (string, optional, default pool address) The hydra address to receive the change
"changePosition" (numeric, optional, default random) The index of the change output
"change_type" (string, optional) The output type to use. Only valid if changeAddress is not specified. Options are "legacy", "p2sh-segwit", and "bech32". Default is set by -changetype.
"includeWatching" (boolean, optional, default false) Also select inputs which are watch only
"lockUnspents" (boolean, optional, default false) Lock selected unspent outputs
"feeRate" (numeric, optional, default not set: makes wallet determine the fee) Set a specific fee rate in hydra/kB
"subtractFeeFromOutputs" (array, optional) A json array of integers.
The fee will be equally deducted from the amount of each specified output.
The outputs are specified by their zero-based index, before any change output is added.
Those recipients will receive less hydras than you enter in their corresponding amount field.
If no outputs are specified here, the sender pays the fee.
[vout_index,...]
"replaceable" (boolean, optional) Marks this transaction as BIP125 replaceable.
Allows this transaction to be replaced by a transaction with higher fees
"conf_target" (numeric, optional) Confirmation target (in blocks)
"estimate_mode" (string, optional, default=UNSET) The fee estimate mode, must be one of:
"UNSET"
"ECONOMICAL"
"CONSERVATIVE"
}
for backward compatibility: passing in a true instead of an object will result in {"includeWatching":true}
3. iswitness (boolean, optional) Whether the transaction hex is a serialized witness transaction
If iswitness is not present, heuristic tests will be used in decoding

Result:

{
"hex": "value", (string) The resulting raw transaction (hex-encoded string)
"fee": n, (numeric) Fee in hydra the resulting transaction pays
"changepos": n (numeric) The position of the added change output, or -1
}

Examples:

Create a transaction with no inputs

> hydra-cli createrawtransaction "[]" "{\"myaddress\":0.01}"

Add sufficient unsigned inputs to meet the output value

> hydra-cli fundrawtransaction "rawtransactionhex"

Sign the transaction

> hydra-cli signrawtransaction "fundedtransactionhex"

Send the transaction

> hydra-cli sendrawtransaction "signedtransactionhex"

gethexaddress

Converts a base58 pubkeyhash address to a hex address for use in smart contracts.

Arguments:

1. "address" (string, required) The base58 address

Result:

"hexaddress" (string) The raw hex pubkeyhash address for use in smart contracts

Examples:

> hydra-cli gethexaddress "address"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "gethexaddress", "params": ["address"] }' -H 'content-type: text/plain;' http://127.0.0.1:3889/

Test example:

gethexaddress "hTTH1Yr2eKCuDLqfxUyBLCAjmomQ8pyrBt"

Test result:

getrawtransaction

NOTE: By default this function only works for mempool transactions. If the -txindex option is enabled, it also works for blockchain transactions. If the block which contains the transaction is known, its hash can be provided even for nodes without -txindex. Note that if a blockhash is provided, only that block will be searched and if the transaction is in the mempool or other blocks, or if this node does not have the given block available, the transaction will not be found. DEPRECATED: for now, it also works for transactions with unspent outputs.

Return the raw transaction data.

If verbose is 'true', returns an Object with information about 'txid'. If verbose is 'false' or omitted, returns a string that is serialized, hex-encoded data for 'txid'.

Arguments:

1. "txid" (string, required) The transaction id
2. verbose (bool, optional, default=false) If false, return a string, otherwise return a json object
3. "blockhash" (string, optional) The block in which to look for the transaction
Result (if verbose is not set or set to false):
"data" (string) The serialized, hex-encoded data for 'txid'
Result (if verbose is set to true):
{
"in_active_chain": b, (bool) Whether specified block is in the active chain or not (only present with explicit "blockhash" argument)
"hex" : "data", (string) The serialized, hex-encoded data for 'txid'
"txid" : "id", (string) The transaction id (same as provided)
"hash" : "id", (string) The transaction hash (differs from txid for witness transactions)
"size" : n, (numeric) The serialized transaction size
"vsize" : n, (numeric) The virtual transaction size (differs from size for witness transactions)
"weight" : n, (numeric) The transaction's weight (between vsize*4-3 and vsize*4)
