What's in the library

GRVT Python SDK library provides Python classes and utility methods for easy access to GRVT API endpoints across all environments.

Environments

• prod - Production environment.
• testnet - Testnet environment.
• staging - Development Integration environment.
• dev - Development environment.

SDK Library provides two types of classes:

1. Raw - thin wrapper classes around Rest API.
2. Ccxt-compatible - classes with ccxt-like methods. Provide access to both Rest API and WebSockets.

Files

Raw access:

• grvt_raw_base.py - base classes for Rest API access.
• grvt_raw_env.py - definitions of environments for raw access.
• grvt_raw_signing.py - utility methods for signing orders.
• grvt_raw_sync.py - class for raw synchronous calls to Rest API.
• grvt_raw_async.py - class for raw asynchronous calls to Rest API.

CCXT-compatible access:

• grvt_ccxt_utils.py - utility methods for signing orders.
• grvt_ccxt_env.py - definitions of environments for ccxt-like access.
• grvt_ccxt_base.py - base class for Rest API access.
• grvt_ccxt.py - class for synchronous calls to Rest API.
• grvt_ccxt_pro.py - class for asynchronous calls to Rest API.
• grvt_ccxt_ws.py - class for WebSocket calls.

Installation via pip

pip install grvt-pysdk

Configuration

Setup these environment variables:

export GRVT_PRIVATE_KEY="`Secret Private Key` in API setup"
export GRVT_API_KEY="`API Key` in API setup"
export GRVT_TRADING_ACCOUNT_ID=<`Trading account ID` in API>
export GRVT_ENV="testnet"
export GRVT_END_POINT_VERSION="v1"
export GRVT_WS_STREAM_VERSION="v1"

Usage

Examples of how to use various methods to connect to GRVT API:

• GRVT CCXT - Example of usage of CCXT-compatible Python class GrvtCcxt with synchronous Rest API calls.
• GRVT CCXT Pro - Example of usage of CCXT.PRO-compatible Python class GrvtCcxtPro with asynchronous Rest API calls.
• GRVT CCXT WS - Example of usage of CCXT.PRO-compatible Python class GrvtCcxtWS with asynchronous Rest API calls + Web Socket subscriptions + JSON RPC calls over Web Sockets.
• GRVT API Sync - Synchronous API client for GRVT
• GRVT API Async - Asynchronous API client for GRVT

Contributor's guide

Prerequisites

• Python >=3.10.0 < 3.13 (tested with 3.10.15)
• pre-commit
• uv >=0.3.3 (tested with 0.4.0)
• docker (optional)

Installation of a source code

1. Clone the git repository

   git clone https://github.com/grvt-technologies/grvt-pysdk.git
   

2. Go into the project directory

   cd grvt-pysdk/
   

3. Checkout working branch

   git checkout <branch>
   

4. Install dependencies

   make install
   

5. Enable pre-commit hooks

   pre-commit install
   

---

Manually run example files

Example files run extensive testing of the SDK API classes and log details about details of using GRVT API.

1. Change to tests folder

   cd tests/pysdk
   

2. Run example of using synchronous CCXT-compatible calls to Rest API via grvt_ccxt.py, class GrvtCcxt

   uv run python3 test_grvt_ccxt.py
   

3. Run example of using asynchronous CCXT-compatible calls to Rest API via grvt_ccxt_pro.py, class GrvtCcxtPro

   uv run python3 test_grvt_ccxt_pro.py
   

4. Run example of using WebSockets subscriptions and JSON RPC calls via grvt_ccxt_ws.py, class GrvtCcxtWS

   uv run python3 test_grvt_ccxt_ws.py
   

What's in the box ?

uv

uv is an extremely fast Python package and project manager, written in Rust.

pyproject.toml file (pyproject.toml): orchestrate your project and its dependencies uv.lock file (uv.lock): ensure that the package versions are consistent for everyone working on your project

For more configuration options and details, see the configuration docs.

pre-commit

pre-commit is a framework for managing and maintaining multi-language pre-commit hooks.

.pre-commit-config.yaml file (.pre-commit-config.yaml): describes what repositories and hooks are installed

For more configuration options and details, see the configuration docs.

ruff

ruff is an extremely fast Python linter, written in Rust.

Rules are defined in the pyproject.toml.

For more configuration options and details, see the configuration docs.

mypy

mypy is an optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing.

Rules are defined in the pyproject.toml.

For more configuration options and details, see the configuration docs.

bandit

bandit is a tool designed to find common security issues in Python code.

Rules are defined in the pyproject.toml.

For more configuration options and details, see the configuration docs.

docformatter

docformatter is a tool designed to format docstrings to follow PEP 257.

Options are defined in the .pre-commit-config.yaml.

Testing

We are using pytest & pytest-cov to write tests.

To run tests with coverage:

make test
