GenLayer Python SDK

GenLayerPY

About

GenLayerPY SDK is a python library designed for developers building decentralized applications (Dapps) on the GenLayer protocol. This SDK provides a comprehensive set of tools to interact with the GenLayer network, including client creation, transaction handling, event subscriptions, and more, all while leveraging the power of web3.py as the underlying blockchain client.

Prerequisites

Before installing GenLayerPY SDK, ensure you have the following prerequisites installed:

• Python (>=3.8)

🛠️ Installation and Usage

To install the GenLayerPY SDK, use the following command:

$ pip install genlayer-py

Here’s how to initialize the client and connect to the GenLayer Simulator:

Reading a Transaction

from genlayer_py import create_client
from genlayer_py.chains import localnet

client = create_client(
    chain=localnet,
)

transaction_hash = "0x..."

transaction = client.get_transaction(hash=transaction_hash)

Waiting for Transaction Receipt

from genlayer_py import create_client
from genlayer_py.chains import localnet
from genlayer_py.types import TransactionStatus

client = create_client(chain=localnet)

# Get simplified receipt (default - removes binary data, keeps execution results)
receipt = client.wait_for_transaction_receipt(
    transaction_hash="0x...",
    status=TransactionStatus.FINALIZED,
    full_transaction=False  # Default - simplified for readability
)

# Get complete receipt with all fields
full_receipt = client.wait_for_transaction_receipt(
    transaction_hash="0x...",
    status=TransactionStatus.FINALIZED,
    full_transaction=True  # Complete receipt with all internal data
)

Reading a contract

from genlayer_py import create_client
from genlayer_py.chains import localnet

client = create_client(
    chain=localnet,
)

result = client.read_contract(
    address=contract_address,
    function_name='get_complete_storage',
    args=[],
    state_status='accepted'
)

Writing a transaction

from genlayer_py.chains import localnet
from genlayer_py import create_client, create_account

client = create_client(
    chain=localnet,
)

account = create_account()

transaction_hash = client.write_contract(
    account=account,
    transaction=transaction,
    address=contract_address,
    function_name='account',
    args=['new_storage'],
    value=0, // value is optional, if you want to send some native token to the contract
)
receipt = client.wait_for_transaction_receipt(
    hash=transaction_hash,
    status=TransactionStatus.FINALIZED, // or ACCEPTED
    full_transaction=False  // False by default - returns simplified receipt for better readability
)

🚀 Key Features

• Client Creation: Easily create and configure a client to connect to GenLayer’s network.
• Transaction Handling: Send and manage transactions on the GenLayer network.
• Gas Estimation*: Estimate gas fees for executing transactions on GenLayer.
