Binance Python Web3 Wallet

This is a client library for the Binance Web3 Wallet API, enabling developers to interact programmatically with Binance's Web3 Wallet platform. The library provides tools to programmatically leverage Binance in-house algorithmic trading capability to automate order execution strategy, improve execution transparency and give users smart access to the available market liquidity through the REST API:

pip install binance-web3-wallet

Documentation

For detailed information, refer to the Binance API Documentation.

REST APIs

All REST API endpoints are available through the rest_api module. Note that some endpoints require authentication using your Binance API credentials.

from binance_sdk_web3_wallet.web3_wallet import (
    Web3Wallet,
    ConfigurationRestAPI,
    WEB3_WALLET_REST_API_PROD_URL,
)

logging.basicConfig(level=logging.INFO)
configuration = ConfigurationRestAPI(api_key="your-api-key", api_secret="your-api-secret", base_path=WEB3_WALLET_REST_API_PROD_URL)

client = Web3Wallet(config_rest_api=configuration_rest_api)

try:
    response = client.rest_api.get_price_info()

    rate_limits = response.rate_limits
    logging.info(f"get_price_info() rate limits: {rate_limits}")

    data = response.data()
    logging.info(f"get_price_info() response: {data}")
except Exception as e:
    logging.error(f"exchange_info() error: {e}")

More examples can be found in the examples/rest_api folder.

Configuration Options

The REST API supports the following advanced configuration options:

• timeout: Timeout for requests in milliseconds (default: 1000 ms).
• proxy: Proxy configuration:
  • host: Proxy server hostname.
  • port: Proxy server port.
  • protocol: Proxy protocol (http or https).
  • auth: Proxy authentication credentials:
    • username: Proxy username.
    • password: Proxy password.
• keep_alive: Enable HTTP keep-alive (default: true).
• compression: Enable response compression (default: true).
• retries: Number of retry attempts for failed requests (default: 3).
• backoff: Delay in milliseconds between retries (default: 1000 ms).
• https_agent: Custom HTTPS agent for advanced TLS configuration.
• private_key: RSA or ED25519 private key for authentication.
• private_key_passphrase: Passphrase for the private key, if encrypted.

Timeout

You can configure a timeout for requests in milliseconds. If the request exceeds the specified timeout, it will be aborted. See the Timeout example for detailed usage.

Proxy

The REST API supports HTTP/HTTPS proxy configurations. See the Proxy example for detailed usage.

Keep-Alive

Enable HTTP keep-alive for persistent connections. See the Keep-Alive example for detailed usage.

Compression

Enable or disable response compression. See the Compression example for detailed usage.

Retries

Configure the number of retry attempts and delay in milliseconds between retries for failed requests. See the Retries example for detailed usage.

HTTPS Agent

Customize the HTTPS agent for advanced TLS configurations. See the HTTPS Agent example for detailed usage.

Key Pair Based Authentication

The REST API supports key pair-based authentication for secure communication. You can use RSA or ED25519 keys for signing requests. See the Key Pair Based Authentication example for detailed usage.

Certificate Pinning

To enhance security, you can use certificate pinning with the https_agent option in the configuration. This ensures the client only communicates with servers using specific certificates. See the Certificate Pinning example for detailed usage.

Error Handling

The REST API provides detailed error types to help you handle issues effectively:

• ClientError: Represents an error that occurred in the SDK client.
• RequiredError: Thrown when a required parameter is missing or undefined.
• UnauthorizedError: Indicates missing or invalid authentication credentials.
• ForbiddenError: Access to the requested resource is forbidden.
• TooManyRequestsError: Rate limit exceeded.
• RateLimitBanError: IP address banned for exceeding rate limits.
• ServerError: Internal server error, optionally includes a status code.
• NetworkError: Issues with network connectivity.
• NotFoundError: Resource not found.
• BadRequestError: Invalid request or one that cannot be served.

See the Error Handling example for detailed usage.

If basePath is not provided, it defaults to https://web3.binance.com/build.

Websocket Streams

WebSocket Streams provide real-time data feeds for market trades, candlesticks, and more. Use the websocket-streams module to subscribe to these streams.

import asyncio
import logging

from binance_web3_common.configuration import ConfigurationWebSocketStreams
from binance_sdk_web3_wallet.web3_wallet import Web3Wallet

logging.basicConfig(level=logging.INFO)

configuration_ws_streams = ConfigurationWebSocketStreams(
    api_key="api-key",
    api_secret="api-secret",
)

client = Web3Wallet(config_ws_streams=configuration_ws_streams)


async def price_stream():
    connection = None
    try:
        connection = await client.websocket_streams.create_connection()

        stream = await connection.price_stream(
            chain_id="CT_501",
            contract_address="C3DwDjT17gDvvCYC2nsdGHxDHVmQRdhKfpAdqQ29pump",
        )
        stream.on("message", lambda data: print(f"{data}"))
    except Exception as e:
        logging.error(f"price_stream() error: {e}")

if __name__ == "__main__":
    asyncio.run(price_stream())

More examples are available in the examples/websocket-streams folder.

Configuration Options

The WebSocket Streams API supports the following advanced configuration options:

• reconnect_delay: Delay (ms) between reconnections.
• compression: Enable response compression.
• mode: Choose between single and pool connection modes.
  • single: A single WebSocket connection.
  • pool: A pool of WebSocket connections.
• pool_size: Define the number of WebSocket connections in pool mode.
• https_agent: Custom HTTPS agent for advanced TLS configuration.
• user_agent: Custom user agent string for WebSocket Streams.
• wsTokenEndpoint: Endpoint to retrieve a WebSocket token for authentication (default: /api/v1/dex/market/wss/auth/token).
• wsToken: Provide a WebSocket token for authentication if needed (default: token retrieved from wsTokenEndpoint automatically).

Reconnect Delay

Specify the delay in milliseconds between WebSocket reconnection attempts for streams. See the Reconnect Delay example for detailed usage.

Compression

Enable or disable compression for WebSocket Streams messages. See the Compression example for detailed usage.

Connection Mode

Choose between single and pool connection modes for WebSocket Streams. The single mode uses a single WebSocket connection, while the pool mode uses a pool of WebSocket connections. See the Connection Mode example for detailed usage.

WebSocket Http Agent

Customize the agent for advanced configurations. See the WebSocket Http Agent example for detailed usage.

Unsubscribing from Streams

You can unsubscribe from specific WebSocket streams using the unsubscribe method. This is useful for managing active subscriptions without closing the connection.

import asyncio
import logging

from binance_web3_common.configuration import ConfigurationWebSocketStreams
from binance_sdk_web3_wallet.web3_wallet import Web3Wallet

logging.basicConfig(level=logging.INFO)

configuration_ws_streams = ConfigurationWebSocketStreams(
    api_key="api-key",
    api_secret="api-secret",
)

client = Web3Wallet(config_ws_streams=configuration_ws_streams)


async def price_stream():
    connection = None
    try:
        connection = await client.websocket_streams.create_connection()

        stream = await connection.price_stream(
            chain_id="CT_501",
            contract_address="C3DwDjT17gDvvCYC2nsdGHxDHVmQRdhKfpAdqQ29pump",
        )
        stream.on("message", lambda data: print(f"{data}"))

        await asyncio.sleep(5)
        await stream.unsubscribe()
    except Exception as e:
        logging.error(f"price_stream() error: {e}")
    finally:
        if connection:
            await connection.close_connection(close_session=True)


if __name__ == "__main__":
    asyncio.run(price_stream())

If wsURL is not provided, it defaults to wss://web3-stream.binance.com/w3w.

Automatic Connection Renewal

The WebSocket connection is automatically renewed for both WebSocket API and WebSocket Streams connections, before the 24 hours expiration of the API key. This ensures continuous connectivity.

Testing

To run the tests, ensure you have Poetry installed, then execute the following commands:

poetry install
poetry run pytest ./tests

The tests cover:

• REST API endpoints
• Error handling and edge cases
