safteawallet-py 0.2.0

Python SDK for interacting with SafeTea Multi-Signature Wallets

safteawallet-py

SafteaWallet-Py is a Python SDK for interacting with SafeTea Multi-Signature Wallets on Ethereum-compatible networks.

It provides a simple and modular interface to create new multi-signature wallets, manage transaction proposals, and execute approved transactions. Both synchronous and asynchronous interfaces are available.

Installation

Install the package via pip:

pip install safteawallet-py

Usage

Sync vs Async

	Sync	Async
Import	safteawallet_py	safteawallet_py.aio
Client	SafeTeaClient	AsyncSafeTeaClient
Usage	Regular calls	await all methods

---

Synchronous API

Connecting and Initializing the Client

from safteawallet_py.client import SafeTeaClient

client = SafeTeaClient(
    rpc_url="https://your.rpc.endpoint",
    factory_address="0xYourFactoryAddress",
    private_key="0x...",
)

Creating a New Multi-Signature Wallet

A minimum of two owners is required.

owners = [
    "0xOwnerAddress1",
    "0xOwnerAddress2",
    "0xOwnerAddress3",
]

result = client.factory.create_wallet(owners)
print(f"Wallet: {result.wallet_address}")
print(f"Tx hash: {result.transaction_hash}")

Proposing a Transaction

wallet = client.wallet("0xYourWalletAddress")

expiry = w3.eth.get_block("latest")["timestamp"] + 86400  # 24 hours

tx_index = wallet.submit_transaction(
    to="0xRecipientAddress",
    value=w3.to_wei(1, "ether"),
    data=b"",
    expiry=expiry,
)
print(f"Submitted at index: {tx_index}")

Confirming / Rejecting a Transaction

wallet.confirm_transaction(tx_index)
wallet.reject_transaction(tx_index)

Managing Owners

expiry = w3.eth.get_block("latest")["timestamp"] + 86400

wallet.propose_add_owner("0xNewOwnerAddress", expiry)
wallet.propose_remove_owner("0xOwnerToRemove", expiry)

wallet.confirm_owner_proposal(proposal_index)
wallet.reject_owner_proposal(proposal_index)

---

Async API (safteawallet_py.aio)

The async module mirrors the sync API but every method is a coroutine. Use it with asyncio or any async framework (FastAPI, aiohttp, etc.).

Client

from safteawallet_py.aio import AsyncSafeTeaClient

client = AsyncSafeTeaClient(
    rpc_url="https://your.rpc.endpoint",
    factory_address="0xYourFactoryAddress",
    private_key="0x...",          # optional — omit for read-only use
)

AsyncSafeTeaClient exposes two attributes after construction:

• client.factory — an AsyncSafeTeaFactory instance
• client.account — the LocalAccount derived from private_key, or None

Check connection

await client.check_connection()   # raises ConnectionError if unreachable

Get a wallet instance

wallet = client.wallet("0xYourWalletAddress")  # returns AsyncSafeTeaWallet

---

Factory — AsyncSafeTeaFactory

Create a wallet

from safteawallet_py.aio import AsyncSafeTeaClient

client = AsyncSafeTeaClient(rpc_url=..., factory_address=..., private_key=...)

owners = ["0xOwner1", "0xOwner2", "0xOwner3"]  # minimum 2
result = await client.factory.create_wallet(owners)

print(result.wallet_address)    # checksummed address of the new wallet
print(result.transaction_hash)  # hex tx hash

Raises ValueError if fewer than 2 owners are provided.

Get wallets for a user

wallets = await client.factory.get_user_wallets("0xUserAddress")
# returns List[ChecksumAddress]

---

Wallet — AsyncSafeTeaWallet

Obtain a wallet instance via client.wallet(address) or construct directly:

from safteawallet_py.aio.wallet import AsyncSafeTeaWallet

wallet = AsyncSafeTeaWallet(web3=client.web3, wallet_address="0x...", account=client.account)

All write methods require the account to be one of the wallet's owners, otherwise NotOwnerError is raised.

---

Info

# Full wallet snapshot
info = await wallet.get_info()
# info.address    — wallet address
# info.owners     — list of owner addresses
# info.threshold  — majority threshold (votes needed to execute)

# Individual getters
owners    = await wallet.get_owners()     # List[ChecksumAddress]
threshold = await wallet.get_threshold()  # int

---

Transactions

# Submit a new proposal
expiry = int(time.time()) + 3600   # unix timestamp, must be within 30 days

tx_index = await wallet.submit_transaction(
    to="0xRecipientAddress",
    value=1_000_000_000_000_000_000,  # wei
    data=b"",                          # optional calldata
    expiry=expiry,                     # optional, default 3600s from now
)

# Confirm or reject
await wallet.confirm_transaction(tx_index)
await wallet.reject_transaction(tx_index)

# Read
count = await wallet.get_transaction_count()   # int
tx    = await wallet.get_transaction(tx_index) # Transaction dataclass

Transaction fields:

Field	Type	Description
to	str	Recipient address
value	int	Value in wei
data	bytes	Calldata
status	TxStatus	PENDING, EXECUTED, or CANCELED
confirmations	int	Confirmation vote count
rejections	int	Rejection vote count
expiry	int	Unix timestamp
created_at	int	Unix timestamp

confirm_transaction and reject_transaction validate state before sending and raise:

• SafeTeaError — if already executed or canceled
• AlreadyVotedError — if the caller already voted
• TransactionExpiredError — if the proposal has expired

---

Owner proposals

expiry = int(time.time()) + 3600

# Propose changes
await wallet.propose_add_owner("0xNewOwner", expiry)
await wallet.propose_remove_owner("0xOwnerToRemove", expiry)

# Vote on a proposal
await wallet.confirm_owner_proposal(proposal_index)
await wallet.reject_owner_proposal(proposal_index)

# Read
count    = await wallet.get_owner_proposal_count()      # int
proposal = await wallet.get_owner_proposal(index)       # OwnerProposal dataclass

OwnerProposal fields:

Field	Type	Description
proposed_owner	str	Address being added or removed
proposal_type	ProposalType	ADD or REMOVE
status	TxStatus	PENDING, EXECUTED, or CANCELED
confirmations	int	Confirmation vote count
rejections	int	Rejection vote count
expiry	int	Unix timestamp
created_at	int	Unix timestamp

confirm_owner_proposal and reject_owner_proposal raise ProposalNotFoundError if the index is out of range.

import asyncio
from safteawallet_py.aio import AsyncSafeTeaClient

async def main():
    client = AsyncSafeTeaClient(
        rpc_url="https://your.rpc.endpoint",
        factory_address="0xFactoryAddress",
        private_key="0xYourPrivateKey",
    )

    await client.check_connection()

    # Deploy a new wallet
    result = await client.factory.create_wallet([
        "0xOwner1",
        "0xOwner2",
    ])
    print("Wallet deployed:", result.wallet_address)

    wallet = client.wallet(result.wallet_address)

    # Submit a transaction
    import time
    tx_index = await wallet.submit_transaction(
        to="0xRecipient",
        value=10 ** 18,   # 1 ETH in wei
        expiry=int(time.time()) + 3600,
    )
    print("Submitted tx index:", tx_index)

    # Second owner confirms
    client2 = AsyncSafeTeaClient(
        rpc_url="https://your.rpc.endpoint",
        factory_address="0xFactoryAddress",
        private_key="0xOwner2PrivateKey",
    )
    wallet2 = client2.wallet(result.wallet_address)
    await wallet2.confirm_transaction(tx_index)
    print("Transaction confirmed and executed.")

asyncio.run(main())
