colibri-stateless 1.1.3

Python bindings for Colibri stateless Ethereum proof library

Colibri Python Bindings (corpus core colibri client)

The colibri client is a stateless and trustless ethereum client, which is optimized for the mobile apps or embedded devices, because it does not hols the state, but verifies on demand.

🚀 Quick Start

Installation

python3 -m pip install colibri-stateless

Basic Usage

import asyncio
from colibri import Colibri

async def main():
    # Initialize client for Ethereum Mainnet
    client = Colibri(chain_id=1, provers=["https://mainnet.colibri-proof.tech"])
    
    # Make verified RPC call
    result = await client.rpc("eth_blockNumber", [])
    print(f"Current block: {result}")
    
    # Get account balance with proof verification
    balance = await client.rpc("eth_getBalance", [
        "0x95222290DD7278Aa3Ddd389Cc1E1d165CC4BAfe5", 
        "latest"
    ])
    print(f"Balance: {balance}")

# Run async function
asyncio.run(main())

✨ Key Features

🛠️ Development

Building from Source

# Clone repository
git clone https://github.com/corpus-core/colibri-stateless.git
cd colibri-stateless/bindings/python

# Build native extension
./build.sh

# Option 1: Use virtual environment (recommended)
python3 -m venv venv
source venv/bin/activate
pip install -e .
pip install -r requirements-dev.txt

# Run tests
pytest tests/ -v

# Deactivate when done
deactivate

Alternative without virtual environment:

# Install test dependencies with --user flag
python3 -m pip install --user pytest pytest-asyncio aiohttp

# Run tests directly with PYTHONPATH
PYTHONPATH=src python3 -m pytest tests/ -v

Quick Debug Build

For faster iteration during development:

# Build in debug mode
./build_debug.sh

# Run tests without installation
PYTHONPATH=src python3 -m pytest tests/ -v

Integration Tests

# Run with real blockchain data (offline)
from colibri.testing import discover_tests, run_test_case

tests = discover_tests()
for test_name, test_config in tests.items():
    result = await run_test_case(test_name, test_config)
    print(f"Test {test_name}: {'PASSED' if result else 'FAILED'}")

📋 System Requirements

• Python 3.8+
• CMake 3.20+ (for building from source)
• C++17 compiler (for building from source)
