CreateMultiSig

The createmultisig RPC creates a P2SH multi-signature address.

Parameter #1---the number of signatures required

NameTypePresenceDescription
Requirednumber (int)Required
(exactly 1)
The minimum (m) number of signatures required to spend this m-of-n multisig script

Parameter #2---the full public keys

❗️

Deprecation Warning

As of Dash Core 0.17.0, using addresses with createmultisig is unsupported. Clients must use addmultisigaddress to create multisig addresses.

NameTypePresenceDescription

(exactly 1)
An array of strings with each string being a public key

Key
stringRequired
(1 or more)
A public key against which signatures will be checked. There must be at least as many keys as specified by the Required parameter, and there may be more keys

Result---P2SH address and hex-encoded redeem script

NameTypePresenceDescription

address
string (base58)Required
(exactly 1)
The P2SH address for this multisig redeem script

EstimateSmartFee

The estimatesmartfee RPC estimates the transaction fee per kilobyte that needs to be paid for a transaction to begin confirmation within a certain number of blocks and returns the number of blocks for which the estimate is valid.

Parameter #1---how many confirmations the transaction may wait before being included

Parameter #2---estimate mode

NameTypePresenceDescription
estimate_modestringOptional
Default=
CONSERVATIVE
The fee estimate mode. Whether to return a more conservative estimate which also satisfies a longer history. A conservative estimate potentially returns a higher feerate and is more likely to be sufficient for the desired target, but is not as responsive to short term drops in the prevailing fee market. Must be one of:
UNSET (defaults to CONSERVATIVE)
ECONOMICAL
CONSERVATIVE

Result---the fee the transaction needs to pay per kilobyte

NameTypePresenceDescription

  "blocks": 6
}

Requesting data the node can't calculate (out of range):

  • ImportAddress: adds an address or pubkey script to the wallet without the associated private key, allowing you to watch for transactions affecting that address or pubkey script without being able to spend any of its outputs.
  • GetNewAddress: returns a new Dash address for receiving payments. If an account is specified, payments received with the address will be credited to that account.
  • GetAddressInfo: returns information about the given Dash address.

VerifyMessage

The verifymessage RPC verifies a signed message.

Parameter #1---the address corresponding to the signing key

NameTypePresenceDescription
Addressstring (base58)Required
(exactly 1)
The P2PKH address corresponding to the private key which made the signature. A P2PKH address is a hash of the public key corresponding to the private key which made the signature. When the ECDSA signature is checked, up to four possible ECDSA public keys will be reconstructed from from the signature; each key will be hashed and compared against the P2PKH address provided to see if any of them match. If there are no matches, signature validation will fail

Parameter #2---the signature

NameTypePresenceDescription
Signaturestring (base64)Required
(exactly 1)
The signature created by the signer encoded as base-64 (the format output by the signmessage RPC)

Parameter #3---the message

NameTypePresenceDescription
MessagestringRequired
(exactly 1)
The message exactly as it was signed (e.g. no extra whitespace)

Result: true, false, or an error

NameTypePresenceDescription
resultbooleanRequired
(exactly 1)
Set to true if the message was signed by a key corresponding to the provided P2PKH address; set to false if it was not signed by that key; set to JSON null if an error occurred

Example from Dash Core 0.12.2

Check the signature on the message created in the example for
signmessage:

dash-cli -testnet verifymessage \
  yNpezfFDfoikDuT1f4iK75AiLp2YLPsGAb \
  H4XULzfHCf16In2ECk9Ta9QxQPq639zQto2JA3OLlo3JbUdrClvJ89+A1z+Z9POd6l8LJhn1jGpQYF8mX4jkQvE= \
  'Hello, World!'

Result:

true
