multisig-transaction.markdown

How to use

Replace every entry like InputTransaction1ID with the actual value it describes.

Example:

• MultisigAddress → 9CXZXhnhp8HBx12Zr6JJmJmTm8qQWrsR6r
• InputTransaction1ID → bde678d3497d794992840d37b30637b03ba0c72b4355cc48bc42bf261fddd9d9
• InputTransaction1N → 1
• TargetAddress1 → 8dueh4ZZnifxdeVezqm8kEPEiiq2XZkdCa
• TargetAddress1Amount → 0.99

<RawInputTransaction1> means an output (from a command) that you use to replace an entry with.

You need to know InputTransaction1ID to get <RawInputTransaction1> that you then replace every mention of RawInputTransaction1 with.

Template:

createrawtransaction '[{"txid":"InputTransaction1ID","vout":InputTransaction1N}]' '{"TargetAddress1":TargetAddress1Amount}'

<RawTransaction>

Actual command and output:

createrawtransaction '[{"txid":"bde678d3497d794992840d37b30637b03ba0c72b4355cc48bc42bf261fddd9d9","vout":1}]' '{"8dueh4ZZnifxdeVezqm8kEPEiiq2XZkdCa":0.99}'

Input #1

• Amount: InputTransaction1Amount BKS
• N: InputTransaction1N
• Script: InputTransaction1ScriptPubKey

(Re-)create multisig address in wallet

• Set RequiredSigners to 3 for a 3-of-x multisig address.
• Add x amount of public keys that those in possession of their respective private keys should be able to sign transactions for the multisig address.

3-of-5 multisig address

createmultisig RequiredSigners '["PublicKey1", "PublicKey2", "PublicKey3", "PublicKey4", "PublicKey5"]'

{
"address" : "MultisigAddress",
"redeemScript" : "RedeemScript"
}

Create transaction

Any unspent input amount becomes the transaction fee.

createrawtransaction '[{"txid":"InputTransaction1ID","vout":InputTransaction1N}]' '{"TargetAddress1":TargetAddress1Amount}'

<RawTransaction>

Sign transaction

Use a private key in WIF format corresponding to one of the public keys specified at creation.

signrawtransaction 'RawTransaction' '[{"txid":"InputTransaction1ID","vout":InputTransaction1N,"scriptPubKey":"InputTransaction1ScriptPubKey","redeemScript":"RedeemScript"}]' '["PrivateKeyWIF"]'

{
"hex" : "<SignedRawTransaction>",
"complete" : false
}

Transaction

Signed 1 of 3-of-5.
