Create a raw transaction

Creates a raw (unsigned) transaction from a list of inputs and outputs. This is the first step in building a custom transaction before signing and broadcasting.

Usage

mc_create_raw_transaction(conn, inputs, outputs, data = list(), action = "")

Arguments

conn

A connection object created by mc_connect.

inputs

A list of input objects, each containing:

• txid – Transaction ID of the UTXO.

• vout – Output index (vout) of the UTXO.

outputs

A named list (or list of named lists) mapping addresses to amounts. Example: list("address1" = 0.5, "address2" = list(asset = 10)).

data

Optional array of metadata. Each element can be a string or a list (which will be converted to JSON then hex). The data is embedded in the transaction outputs.

action

Optional action string: "lock" (lock inputs), "sign" (sign the transaction), "lock,sign" (both), or "send" (sign and send). Default is "" (just create).

Value

A character string containing the raw transaction hex (if no action) or a list with hex and complete if action includes signing.

Other raw transactions: mc_append_raw_change(), mc_append_raw_data(), mc_append_raw_transaction(), mc_create_raw_send_from(), mc_decode_raw_transaction(), mc_send_raw_transaction(), mc_sign_raw_transaction()

Examples

if (FALSE) { # \dontrun{
# Build a simple transaction
inputs <- list(list(txid = "abc...", vout = 0))
outputs <- list("1A..." = 1.0)
tx_hex <- mc_create_raw_transaction(conn, inputs, outputs)

# With metadata
tx_hex <- mc_create_raw_transaction(conn, inputs, outputs,
                                    data = list("Hello", list(key = "value")))
} # }
