Simple

Riemann offers a simplified transaction builder that accepts human-readable inputs, i.e. integers and strings instead of serialized LE numbers and bytestrings.

riemann.simple.outpoint(tx_id, index, tree=None)

Some overloads are not documented by Sphinx

hex_str, int, int -> Outpoint accepts block explorer txid string

riemann.simple.output(value: int, address: str) → riemann.tx.tx.TxOut

int, str -> TxOut accepts base58 or bech32 addresses

riemann.simple.unsigned_input(outpoint, sequence=4294967294)

Some overloads are not documented by Sphinx

Outpoint, byte-like, int -> TxIn

riemann.simple.unsigned_legacy_tx(tx_ins, tx_outs, **kwargs)

Create an unsigned transaction Use this to generate sighashes for unsigned TxIns Hint: set version to 2 if using sequence number relative time locks

Parameters

• list (tx_outs) – list of transaction inputs

• list – list of transaction outputs

• **kwargs –

• version (int) – transaction version number

• lock_time (hex) – transaction locktime

• expiry (int) – overwinter expiry time

• tx_joinsplits (list) – list of joinsplits transactions

• joinsplit_pubkey (bytes) – joinsplit public key

• joinsplit_sig (bytes) – joinsplit signature

Returns

unsigned transaction

Return type

(Tx instance)

riemann.simple.unsigned_witness_tx(tx_ins, tx_outs, **kwargs)

Create an unsigned segwit transaction Create an unsigned segwit transaction Use this to generate sighashes for unsigned TxIns Hint: set version to 2 if using sequence number relative time locks

Parameters

• list (tx_outs) – list of transaction inputs

• list – list of transaction outputs

• **kwargs –

• version (int) – transaction version number

• locktime (hex) – transaction locktime

Returns

unsigned transaction with empty witness

Return type

(Tx instance)
