safe-kit 0.0.2

Python implementation of the Safe Protocol Kit

Safe Kit (Python)

A Python implementation of the Safe Protocol Kit, designed to mirror the developer experience of the official Node.js SDK.

Features

• DX First: Intuitive API for interacting with Safe smart accounts.
• Type Safe: Built with Pydantic and fully typed for robust development.
• Modern Stack: Uses Web3.py, Eth-account, and Python 3.10+.
• Full Protocol Support: Supports Safe deployment, transaction creation, signing (EIP-712 & eth_sign), and execution.

Installation

This project uses Poetry for dependency management.

# Install dependencies
poetry install

Usage

Initialization

from web3 import Web3
from eth_account import Account
from safe_kit.safe import Safe
from safe_kit.adapter import Web3Adapter

# Setup Web3 and Signer
w3 = Web3(Web3.HTTPProvider("RPC_URL"))
owner = Account.from_key("PRIVATE_KEY")
adapter = Web3Adapter(web3=w3, signer=owner)

# Initialize Safe
safe = Safe(eth_adapter=adapter, safe_address="0xSafeAddress")

Creating and Signing Transactions

from safe_kit.types import SafeTransactionData

# Create a transaction (e.g., send ETH)
tx_data = SafeTransactionData(
    to="0xRecipient",
    value=1000000000000000000, # 1 ETH
    data="0x"
)

safe_tx = safe.create_transaction(tx_data)

# Sign the transaction
# Supports "eth_sign_typed_data" (default, EIP-712) or "eth_sign" (legacy)
signed_tx = safe.sign_transaction(safe_tx)

Executing Transactions

# Execute the transaction on-chain
tx_hash = safe.execute_transaction(signed_tx)
print(f"Transaction executed: {tx_hash}")
