web3o

A lightweight, fast Python library for Ethereum JSON-RPC. Built as a minimal alternative to web3.py with low overhead and a small, explicit API.

Install

pip install web3o

Usage

from web3o.provider import HttpProvider
from web3o.contract import Contract

provider = HttpProvider("https://eth.llamarpc.com")

# Query chain state
block_number = provider.get_block_number()

# Call a contract
usdc = Contract(address="0xA0b...", abi=ABI, provider=provider)
response = usdc.functions.balanceOf("0x...").call()

Why web3o

• Minimal: No middleware stacks or heavy abstractions, just direct JSON-RPC wrappers.
• Fast: Low per-call overhead; uses orjson and httpx under the hood.
• Typed: Modern Python 3.11+ type hints throughout.
• Small API surface: Easy to learn and maintain.
