## Overview

Arbitrum Python SDK simplifies the process of interacting with Arbitrum chains, offering a robust set of tools for asset bridging and cross-chain messaging.

## Installation

```bash
pip3 install arbitrum_py
```

## Key Features

### Bridging Assets

Arbitrum Python SDK facilitates the bridging of assets between an Arbitrum chain and its parent chain. Currently supported asset bridgers:

- `EthBridger`: For bridging ETH to and from an Arbitrum chain (L2 or L3)
- `Erc20Bridger`: For bridging ERC-20 tokens to and from an Arbitrum chain (L2 or L3)
- `EthL1L3Bridger`: For bridging ETH to an L3 directly from L1
- `Erc20L1L3Bridger`: For bridging ERC-20 tokens to an L3 directly from L1

### Cross-Chain Messages

Cross-chain communication is handled through `ParentToChildMessage` and `ChildToParentMessage` classes. These encapsulate the lifecycle of messages sent between chains, typically created from transaction receipts that initiate cross-chain messages.

### Network Configuration

The SDK comes preconfigured for Arbitrum One, Arbitrum Nova and Arbitrum Sepolia. Custom Arbitrum networks can be registered using `register_custom_arbitrum_network`, which is required before utilizing other SDK features.

## Usage

Here's a basic example of using the SDK to bridge ETH:

```python
from web3 import Web3
from eth_account import Account
from arbitrum_py.data_entities.networks import get_arbitrum_network
from arbitrum_py.asset_bridger.eth_bridger import EthBridger
from arbitrum_py.data_entities.signer_or_provider import SignerOrProvider

def bridge_eth(parent_signer: SignerOrProvider, child_chain_id: int):
    child_network = get_arbitrum_network(child_chain_id)
    eth_bridger = EthBridger(child_network)

    deposit = eth_bridger.deposit({
        'amount': Web3.to_wei(0.1, 'ether'),
        'parentSigner': parent_signer,
    })

    print(f"Deposit initiated: {deposit['transactionHash'].hex()}")
```

For more detailed usage examples and API references, please refer to the [Arbitrum Python SDK documentation](https://arbitrum-python-sdk.readthedocs.io) or check out the [tutorials](https://github.com/justmert/arbitrum-python-tutorials)

## Running Tests

1. Set up test nodes by following the instructions [here](https://docs.arbitrum.io/run-arbitrum-node/run-local-full-chain-simulation) or below quick setup:

  ```sh
  # Make sure docker is installed
  git clone -b release --recurse-submodules https://github.com/OffchainLabs/nitro-testnode.git && cd nitro-testnode
  chmod +x ./test-node.bash && && ./test-node.bash --init --tokenbridge --l3node --l3-token-bridge --blockscout --detach

  # (Optional) You can fund default accounts with ETH using the following command
  # https://docs.arbitrum.io/run-arbitrum-node/run-local-full-chain-simulation#blockscout

  # Send 5 ETH to the dev account in L2 network. 
  ./test-node.bash script send-l2 --to 0x3f1Eae7D46d88F08fc2F8ed27FCb2AB183EB2d0E --ethamount 5

  # Send 5 ETH to the dev account in 12 network. 
  ./test-node.bash script send-l1 --to 0x3f1Eae7D46d88F08fc2F8ed27FCb2AB183EB2d0E --ethamount 5
  ```

1. Copy `.env.example` to `.env` and update relevant environment variables.

2. Install dependencies:

  ```sh
  pip install -r requirements.txt
  ```

4. Generate the network configuration against your active Nitro test node:

  ```sh
  python3 -m scripts.gen_network
  ```

5. Execute the integration tests:

  ```sh
  pytest tests
  ```
