Quick Start

pip install python-binance-chain

If having issues with secp256k1 check the Installation instructions for the sec256k1-py library

If using the production server there is no need to pass the environment variable.

from binance_chain.http import HttpApiClient
from binance_chain.constants import KlineInterval
from binance_chain.environment import BinanceEnvironment

# initialise with Testnet environment
testnet_env = BinanceEnvironment.get_testnet_env()
client = HttpApiClient(env=testnet_env)

# Alternatively pass no env to get production
prod_client = HttpApiClient()

# connect client to different URL using custom environments, see below

# get node time
time = client.get_time()

# get node info
node_info = client.get_node_info()

# get validators
validators = client.get_validators()

peers = client.get_peers()

# get account
account = client.get_account('tbnb185tqzq3j6y7yep85lncaz9qeectjxqe5054cgn')

# get account sequence
account_seq = client.get_account_sequence('tbnb185tqzq3j6y7yep85lncaz9qeectjxqe5054cgn')

# get markets
markets = client.get_markets()

See API docs for more information.

Async HTTP Client

An implementation of the HTTP Client above using aiohttp instead of requests

Use the async create classmethod to initialise an instance of the class.

All methods are otherwise the same as the HttpApiClient

from binance_chain.http import AsyncHttpApiClient
from binance_chain.environment import BinanceEnvironment
import asyncio

loop = None

async def main():
    global loop

    env = BinanceEnvironment.get_testnet_env()

    # initialise the class using the classmethod
    client = await AsyncHttpApiClient.create(env)
    wallet = Wallet(private_key=priv_key, env=env)

    print(json.dumps(await client.get_time(), indent=2))

    while True:
        print("doing a sleep")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Environments

Binance Chain offers a Production system and Testnet.

If using the Production system there is no need to pass an environment as this is the default.

To create and use the Testnet environment is as easy as

from binance_chain.environment import BinanceEnvironment

# initialise with Testnet environment
testnet_env = BinanceEnvironment.get_testnet_env()

You may also create your own custom environments, this may be useful such as connecting to a Node RPC client

from binance_chain.environment import BinanceEnvironment

# create custom environment
my_env = BinanceEnvironment(api_url="<api_url>", wss_url="<wss_url>", hrp="<hrp>")

See API docs for more information.

Wallet

See API docs for more information.

The wallet is required if you want to place orders, transfer funds or freeze and unfreeze tokens.

You may also use the Ledger Wallet class to utilise your Ledger Hardware Wallet for signing.

It can be initialised with your private key or your mnemonic phrase.

You can additionally provide BIP39 passphrase and derived wallet id.

Note that the BinanceEnvironment used for the wallet must match that of the HttpApiClient, testnet addresses will not work on the production system.

The Wallet class can also create a new account for you by calling the Wallet.create_random_wallet() function, see examples below

Initialise from Private Key

from binance_chain.wallet import Wallet
from binance_chain.environment import BinanceEnvironment

testnet_env = BinanceEnvironment.get_testnet_env()
wallet = Wallet('private_key_string', env=testnet_env)
print(wallet.address)
print(wallet.private_key)
print(wallet.public_key_hex)

Initialise from Mnemonic

from binance_chain.wallet import Wallet
from binance_chain.environment import BinanceEnvironment

testnet_env = BinanceEnvironment.get_testnet_env()
wallet = Wallet.create_wallet_from_mnemonic('mnemonic word string',
                                             passphrase='optional passphrase',
                                             child=0,
                                             env=testnet_env)
print(wallet.address)
print(wallet.private_key)
print(wallet.public_key_hex)

Initialise by generating a random Mneomonic

from binance_chain.wallet import Wallet
from binance_chain.environment import BinanceEnvironment

testnet_env = BinanceEnvironment.get_testnet_env(, env=testnet_env)
wallet = Wallet.create_random_wallet(env=env)
print(wallet.address)
print(wallet.private_key)
print(wallet.public_key_hex)

Broadcast Messages on HttpApiClient

See API docs for more information.

Requires a Wallet to have been created.

The Wallet will increment the request sequence when broadcasting messages through the HttpApiClient.

If the sequence gets out of sync call wallet.reload_account_sequence(client), where client is an instance of HttpApiClient.

vote_msg = VoteMsg(
    wallet=wallet,
    proposal_id=1,
    vote_option=VoteOption.YES
)
res = client.broadcast_msg(vote_msg, sync=True)

Sign Transaction

If you want to simply sign a transaction you can do that as well.

This is a transfer example

from binance_chain.messages import TransferMsg, Signature
from binance_chain.wallet import Wallet

wallet = Wallet('private_key_string')

transfer_msg = TransferMsg(
    wallet=wallet,
    symbol='BNB',
    amount=1,
    to_address='<to address>'
)
signed_msg = Signature(transfer_msg).sign()

Websockets

See API docs for more information.

import asyncio

from binance_chain.websockets import BinanceChainSocketManager
from binance_chain.environment import BinanceEnvironment

testnet_env = BinanceEnvironment.get_testnet_env()

address = 'tbnb...'
loop = None

async def main():
    global loop

    async def handle_evt(msg):
        """Function to handle websocket messages
        """
        print(msg)

    # connect to testnet env
    bcsm = await BinanceChainSocketManager.create(loop, handle_evt, address, env=testnet_env)

    # subscribe to relevant endpoints
    await bcsm.subscribe_orders(address)
    await bcsm.subscribe_market_depth(["FCT-B60_BNB", "0KI-0AF_BNB"])
    await bcsm.subscribe_market_delta(["FCT-B60_BNB", "0KI-0AF_BNB"])
    await bcsm.subscribe_trades(["FCT-B60_BNB", "0KI-0AF_BNB"])
    await bcsm.subscribe_ticker(["FCT-B60_BNB", "0KI-0AF_BNB"])

    while True:
        print("sleeping to keep loop open")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Unsubscribe

# with an existing BinanceChainSocketManager instance

await bcsm.unsubscribe_orders()

# can unsubscribe from a particular symbol, after subscribing to multiple
await bcsm.subscribe_market_depth(["0KI-0AF_BNB"])

Close Connection

# with an existing BinanceChainSocketManager instance

await bcsm.close_connection()

Node RPC HTTP

See API docs for more information.

The binance_chain.http.HttpApiClient has a helper function get_node_peers() which returns a list of peers with Node RPC functionality

from binance_chain.http import HttpApiClient, PeerType
from binance_chain.node_rpc import HttpRpcClient

httpapiclient = HttpApiClient()

# get a peer that support node requests
peers = httpapiclient.get_node_peers()
listen_addr = peers[0]['listen_addr']

# connect to this peer
rpc_client = HttpRpcClient(listen_addr)

# test some endpoints
abci_info = rpc_client.get_abci_info()
consensus_state = rpc_client.dump_consensus_state()
genesis = rpc_client.get_genesis()
net_info = rpc_client.get_net_info()
num_unconfirmed_txs = rpc_client.get_num_unconfirmed_txs()
status = rpc_client.get_status()
health = rpc_client.get_health()
unconfirmed_txs = rpc_client.get_unconfirmed_txs()
validators = rpc_client.get_validators()

block_height = rpc_client.get_block_height(10)

Node RPC HTTP Async

An aiohttp implementation of the Node RPC HTTP API.

Use the async create classmethod to initialise an instance of the class.

All methods are the same as the binance_chain.node_rpc.http.HttpRpcClient.

from binance_chain.node_rpc.http import AsyncHttpRpcClient
from binance_chain.http import AsyncHttpApiClient, PeerType
from binance_chain.environment import BinanceEnvironment
import asyncio

loop = None

async def main():
    global loop

    testnet_env = BinanceEnvironment.get_testnet_env()

    # create the client using the classmethod
    http_client = await AsyncHttpApiClient.create(env=testnet_env)

    peers = await http_client.get_node_peers()
    listen_addr = peers[0]['listen_addr']

    rcp_client = await AsyncHttpRpcClient.create(listen_addr)

    print(json.dumps(await rcp_client.get_abci_info(), indent=2))

    while True:
        print("doing a sleep")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Broadcast Messages on Node RPC HTTP Client

Requires a Wallet to have been created

The Wallet will increment the request sequence when broadcasting messages through the HttpApiClient.

If the sequence gets out of sync call wallet.reload_account_sequence(client), where client is an instance of HttpApiClient.

Place Order

from binance_chain.node_rpc import HttpRpcClient
from binance_chain.messages import LimitOrderBuyMsg
from binance_chain.wallet import Wallet
from binance_chain.constants import RpcBroadcastRequestType

wallet = Wallet('private_key_string')
rpc_client = HttpRpcClient(listen_addr)

limit_order_msg = LimitOrderBuyMsg(
    wallet=wallet,
    symbol='ANN-457_BNB',
    price=0.000396000,
    quantity=12
)

# then broadcast it, by default in synchronous mode
res = rpc_client.broadcast_msg(limit_order_msg)

# alternative async request
res = rpc_client.broadcast_msg(new_order_msg, request_type=RpcBroadcastRequestType.ASYNC)

# or commit request
res = rpc_client.broadcast_msg(new_order_msg, request_type=RpcBroadcastRequestType.COMMIT)

Other messages can be constructed similar to examples above

Pooled Node RPC Client

This client connects to all available peer nodes in the network and spreads requests across them.

This helps reduce API rate limit errors.

The interface is the same as the above HttpRpcClient and AsyncHttpRpcClient classes for consistency.

Requests can be sent using asyncio gather note to check the number of clients connected to and not exceed that amount

import asyncio
from binance_chain.node_rpc.pooled_client import PooledRpcClient


async def main():

    # initialise the client, default production environment
    client = await PooledRpcClient.create()

    # optionally include an environment
    testnet_env = BinanceEnvironment.get_testnet_env()
    client = await PooledRpcClient.create(env=testnet_env)

    # show the number of peers connected with the num_peers property
    print(f"Connected to {client.num_peers} peers")

    # requests can be send in bulk using asyncio gather
    for i in range(0, 5):
        res = await asyncio.gather(
            client.get_abci_info(),
            client.get_consensus_state(),
            client.get_net_info(),
            client.get_status(),
            client.get_health(),
        )
        print(f'{i}: {res}')

    print(await client.get_block(1000))

    print(await client.get_blockchain_info(1000, 2000))

if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

To keep the peer connections up to date you may re-initialise the list of peers by calling the initialise_peers function

client.initialise_peers()

Node RPC Websockets

See API docs for more information.

For subscribe query examples see the documentation here

import asyncio

from binance_chain.http import HttpApiClient
from binance_chain.environment import BinanceEnvironment
from binance_chain.node_rpc.websockets import WebsocketRpcClient

loop = None

async def main():
    global loop

    async def handle_evt(msg):
        print(msg)

    # find node peers on testnet
    testnet_env = BinanceEnvironment.get_testnet_env()
    client = HttpApiClient(testnet_env)

    peers = client.get_node_peers()

    # construct websocket listen address - may not be correct
    listen_addr = re.sub(r"^https?:\/\/", "tcp://", peers[0]['listen_addr'])

    # create custom environment for RPC Websocket
    node_env = BinanceEnvironment(
        api_url=testnet_env.api_url,
        wss_url=listen_addr,
        hrp=testnet_env.hrp
    )

    wrc = await WebsocketRpcClient.create(loop, handle_evt, env=node_env)

    await wrc.subscribe("tm.event = 'NewBlock'")
    await wrc.abci_info()

    while True:
        print("sleeping to keep loop open")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Unsubscribe

# with an existing WebsocketRpcClient instance

await wrc.unsubscribe("tm.event = 'NewBlock'")

Unsubscribe All

# with an existing WebsocketRpcClient instance

await wrc.unsubscribe_all()

Depth Cache

Follow the order book for a specified trading pair.

Note: This may not be 100% reliable as the response info available from Binance Chain may not always match up

from binance_chain.depthcache import DepthCacheManager
from binance_chain.environment import BinanceEnvironment
from binance_chain.http import HttpApiClient

dcm = None
loop = None


async def main():
    global dcm1, loop

    async def process_depth(depth_cache):
        print("symbol {}".format(depth_cache.symbol))
        print("1: top 5 asks")
        print(depth_cache.get_asks()[:5])
        print("1: top 5 bids")
        print(depth_cache.get_bids()[:5])

    env = BinanceEnvironment.get_testnet_env()
    client = HttpApiClient(env=env)

    dcm = await DepthCacheManager.create(client, loop, "100K-9BC_BNB", process_depth, env=env)

    while True:
        print("doing a sleep")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Signing Service

A Service to sign and optionally also broadcast messages for you.

The service holds the private keys of the accounts and supplies a username and password to interact with these accounts.

This client re-uses the binance_chain.messages types. In this case no wallet parameter is required.

This client interacts with the binance-chain-signing-service read the docs there to create our own signing service.

Signing and then broadcasting

from binance_chain.messages import NewOrderMsg
from binance_chain.signing.http import HttpApiSigningClient
from binance_chain.constants import TimeInForce, OrderSide, OrderType

signing_client = HttpApiSigningClient('http://localhost:8000', username='sam', password='mypass')

# print(client.signing_service_auth())

new_order_msg = NewOrderMsg(
    symbol='ANN-457_BNB',
    order_type=OrderType.LIMIT,
    side=OrderSide.BUY,
    price=0.000396000,
    quantity=10,
    time_in_force=TimeInForce.GOOD_TILL_EXPIRE
)
new_order_hex = signing_client.sign_order(new_order_msg, wallet_name='wallet_1')

the sign_order method can also take a binance_chain.messages.LimitOrderBuyMsg or binance_chain.messages.LimitOrderSellMsg instance.

This hex can then be broadcast using the normal HTTP Client like so

from binance_chain.http import HttpApiClient
from binance_chain.environment import BinanceEnvironment

# initialise with environment that is supported by the signing service wallet
testnet_env = BinanceEnvironment.get_testnet_env()
client = HttpApiClient(env=testnet_env)

res = client.broadcast_hex_msg(new_order_hex['signed_msg'], sync=True)

The signing service supports binance_chain.messages types NewOrderMsg, CancelOrderMsg, FreezeMsg, UnFreezeMsg and TransferMsg

Signing and broadcasting in one

To sign and broadcast an order use the broadcast_order method. This returns the response from the Binance Chain exchange.

from binance_chain.messages import NewOrderMsg
from binance_chain.signing.http import HttpApiSigningClient
from binance_chain.constants import TimeInForce, OrderSide, OrderType

signing_client = HttpApiSigningClient('http://localhost:8000', username='sam', password='mypass')

# print(client.signing_service_auth())

new_order_msg = NewOrderMsg(
    symbol='ANN-457_BNB',
    order_type=OrderType.LIMIT,
    side=OrderSide.BUY,
    price=0.000396000,
    quantity=10,
    time_in_force=TimeInForce.GOOD_TILL_EXPIRE
)
res = signing_client.broadcast_order(new_order_msg, wallet_name='wallet_1')

Async Signing Service

Like all other libraries there is an async version.

from binance_chain.signing.http import AsyncHttpApiSigningClient
from binance_chain.http import AsyncHttpApiClient, PeerType
from binance_chain.environment import BinanceEnvironment
from binance_chain.constants import TimeInForce, OrderSide, OrderType
import asyncio

loop = None

async def main():
    global loop

    # create the client using the classmethod
    signing_client = await AsyncHttpApiSigningClient.create('http://localhost:8000', username='sam', password='mypass')

    new_order_msg = NewOrderMsg(
        symbol='ANN-457_BNB',
        order_type=OrderType.LIMIT,
        side=OrderSide.BUY,
        price=0.000396000,
        quantity=10,
        time_in_force=TimeInForce.GOOD_TILL_EXPIRE
    )

    # simply sign the message
    sign_res = await signing_client.sign_order(new_order_msg, wallet_name='wallet_1')

    # or broadcast it as well
    broadcast_res = await signing_client.broadcast_order(new_order_msg, wallet_name='wallet_1')

    print(json.dumps(await rcp_client.get_abci_info(), indent=2))

    while True:
        print("doing a sleep")
        await asyncio.sleep(20, loop=loop)


if __name__ == "__main__":

    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Ledger

Sign transactions with your Ledger wallet, supports Ledger Blue, Nano S and Nano X.

Make sure you have registered on Binance Chain with your Ledger address.

Make sure that you have connected your Ledger and are in the Binance Chain app.

Install python-binance-chain with this optional library like so pip install python-binance-chain[ledger]

Uses the btchip-python library if having issues installing check their github page

from binance_chain.ledger import getDongle, LedgerApp, LedgerWallet
from binance_chain.environment import BinanceEnvironment

dongle = getDongle(debug=True)

testnet_env = BinanceEnvironment.get_testnet_env()
app = LedgerApp(dongle, env=testnet_env)

# get the Ledger Binance app version
print(app.get_version())

# Show your address on the Ledger
print(app.show_address())

# Get your address and public key from the Ledger
print(app.get_address())

# Get your public key from the Ledger
print(app.get_public_key())

Create a Wallet to use with the HTTP and Node RPC clients

# this will prompt you on your Ledger to confirm the address you want to use
wallet = LedgerWallet(app, env=testnet_env)


# now create messages and sign them with this wallet
from binance_chain.http import HttpApiClient
from binance_chain.messages import NewOrderMsg, OrderType, OrderSide, TimeInForce

client = HttpApiClient(env=testnet_env)
new_order_msg = NewOrderMsg(
    wallet=wallet,
    symbol='ANN-457_BNB',

Requests and AioHTTP Settings

python-binance-chain uses requests and aiohttp libraries.

You can set custom requests parameters for all API calls when creating any of the http clients.

client = HttpApiClient(request_params={"verify": False, "timeout": 20})

Check out either the requests documentation or aiohttp documentation for all options.

Proxy Settings

You can use the settings method above

proxies = {
    'http': 'http://10.10.1.10:3128',
    'https': 'http://10.10.1.10:1080'
}

# in the Client instantiation
client = HttpApiClient(request_params={'proxies': proxies})

Or set an environment variable for your proxy if required to work across all requests.

An example for Linux environments from the requests Proxies documentation is as follows.

$ export HTTP_PROXY="http://10.10.1.10:3128"
$ export HTTPS_PROXY="http://10.10.1.10:1080"

For Windows environments

C:\>set HTTP_PROXY=http://10.10.1.10:3128
C:\>set HTTPS_PROXY=http://10.10.1.10:1080
