Monero Python serialization library

Build Status

The library provides basic serialization logic for the Monero types, used in transaction processing and transaction signing.

  • Mainly supports binary serialization equivalent to Monero BEGIN_SERIALIZE_OBJECT(). This serialization mechanism is used in the blockchain entity serialization.
  • Boost portable serialization added.
  • Support for BEGIN_KV_SERIALIZE_MAP is mainly supported. JSON and binary wire format.

The binary wire formats use streaming dumping / parsing for better memory efficiency.

For usage please take a look at tests.

pip install monero-serialize

Example usage:

import binascii
from monero_serialize import xmrserialize as x
from monero_serialize import xmrtypes as xmr

msg = xmr.TxinToKey(amount=123, key_offsets=[1, 2, 3, 2**76], k_image=bytearray(range(32)))

# Serialize
writer = x.MemoryReaderWriter()
await x.dump_message(writer, msg)

# Deserialize
test_deser = await x.load_message(x.MemoryReaderWriter(writer.buffer), xmr.TxinGen)


Thanks for your support!


Advanced usage

Archive interface

import binascii
from monero_serialize import xmrserialize as x
from monero_serialize import xmrtypes as xmr

msg = xmr.TxinGen(height=42)

# Serialize
writer = x.MemoryReaderWriter()
ar1 = x.Archive(writer, True)
await ar1.message(msg)

# Deserialize
msg2 = xmr.TxinGen()
ar2 = x.Archive(x.MemoryReaderWriter(writer.buffer), False)
await ar2.message(msg2)

Symmetric Boost archive

import binascii
from monero_serialize import xmrserialize as x
from monero_serialize import xmrtypes as xmr
from monero_serialize import xmrboost as xmrb

data_hex = b'011673657269616c697a6174696f6e3a3a61726368697665000000000134'
data_bin = base64.b16decode(data_hex, True)
reader = x.MemoryReaderWriter(bytearray(data_bin))
ar = xmrb.Archive(reader, False)

msg = xmr.TxinGen()
await ar.root_message(msg)
self.assertEqual(msg.height, 0x34)
