Serum Python Client

Provides a Python SDK for bloXroute's Serum API.

Installation

$ pip install bxserum

Usage

This library supports HTTP, websockets, and GRPC interfaces. You can use it with a context manager or handle open/closing yourself.

For any methods involving transaction creation you will need to provide your Solana private key. You can provide this via the environment variable PRIVATE_KEY, or specify it via the provider configuration if you want to load it with some other mechanism. See samples for more information. As a general note on this: methods named post_* (e.g. post_order) typically do not sign/submit the transaction, only return the raw unsigned transaction. This isn't very useful to most users (unless you want to write a signer in a different language), and you'll typically want the similarly named submit_* methods (e.g. submit_order). These methods generate, sign, and submit the transaction all at once.

Context manager:

from bxserum import provider

async with provider.http() as api:
    print(await api.get_orderbook(market="ETHUSDT"))
    
async with provider.ws() as api:
    async for update in api.get_orderbooks_stream(market="ETHUSDT"):
        print(update)

Manual:

import bxserum

from bxserum import provider

p = provider.grpc()
api = await bxserum.serum(p)

try:
    await api.get_orderbook(market="ETHUSDT")
finally:
    await p.close()

Refer to the examples/ for more info.

Development

bloXroute Serum API's interfaces are primarily powered by protobuf, so you will need to install it for your system: https://grpc.io/docs/protoc-installation/

Clone project and install dependencies:

$ git clone https://github.com/bloXroute-Labs/serum-client-python.git
$ cd serum-client-python
$ pip install -r requirements.txt

Run tests:

$ make test

Regenerate protobuf files:

$ make proto

Linting:

$ make lint
