aioxrpy

Ripple blockchain library for Python.

Features

1. Async JSON-RPC client.
2. Signing and verifying transactions using private and public keys.
3. Support for signing transactions with multiple keys.
4. Serializer and deserializer for Ripple objects.

Installation

Library is available on PyPi, you can simply install it using pip.

$ pip install aioxrpy

Usage

Keys

Signing and verifying transactions, as well as generating new accounts is done through RippleKey class.

from aioxrpy.keys import RippleKey

# New key
key = RippleKey()

# From public key
key = RippleKey(public_key=b'public key')

# From master seed
key = RippleKey(private_key='seed')

# From private key
key = RippleKey(private_key=b'private key')

Such key can be converted to Account ID and public key.

Submitting transactions

RPC client provides a helper which signs and submits transaction. As a first argument it takes a transaction dict. The second one is a RippleKey instance used for signing this transaction.

from aioxrpy.rpc import RippleJsonRpc

rpc = RippleJsonRpc(url)
await rpc.sign_and_submit(
    {
        'Account': account,
        'TransactionType': RippleTransactionType.Payment,
        'Amount': decimals.xrp_to_drops(200),
        'Destination': destination,
        'Fee': 10
    },
    signer
)

Multi-signed transactions

RPC client provides a helper which signs and submits transaction using multiple keys. As a second argument, it expects a list of RippleKey instances. Please don't forget that each signer increases transaction fees.

from aioxrpy.rpc import RippleJsonRpc

rpc = RippleJsonRpc(url)
await rpc.multisign_and_submit(
    {
        'Account': account,
        'TransactionType': RippleTransactionType.Payment,
        'Amount': decimals.xrp_to_drops(200),
        'Destination': destination,
        'Fee': 30
    },
    [signer_1, signer_2]
)
