# Documentation for the `web3automatization` Library

`web3automatization` is a library for simplifying interactions with EVM-based blockchain networks through `web3py`. It provides convenient methods for account management, transaction sending, ERC-20 token operations, and retrieving network information. The library also includes ready-made modules for interacting with various DeFi projects.

## Features

- Connect to various blockchain networks via RPC.
- Manage accounts using private keys.
- Send native and ERC-20 tokens.
- Perform `approve` operations for ERC-20 tokens.
- Retrieve balances and token information.
- Automatically estimate gas for transactions.

## Supported Projects
- CrossCurve
  - Cross-chain swaps
  - In-chain swaps
- Iotex
  - Bridge in Iotex from Polygon
  - Withdraw from Iotex to Polygon

## Installation

```bash
pip install web3automatization
```

## Usage

### Importing the Client

```python
from web3automatization import Client
```

### Initializing the Client

```python
private_key = "your private key"
rpc_url = "RPC server URL"

client = Client(private_key, rpc_url)
```

**Parameters:**

- `private_key` (str): Your account’s private key in hexadecimal format (with or without the '0x' prefix).
- `rpc_url` (str): URL of the blockchain network’s RPC server.
- `proxy` (str, optional): URL of the proxy server, if connection via proxy is needed.

**Example:**

```python
client = Client(
    private_key="0xc55af4055f19f388765840edee4e929efa333fb3b6a728979d1234567112c556",
    rpc="https://ethereum-rpc.publicnode.com",
    proxy="123.123.12.23:8080"

```python
balance = client.get_native_balance()
print(f"Account balance: {balance} ETH")
```

**Parameters:**

- `address` (str, optional): Address to check the balance for. If not specified, the client’s public key is used.

### Sending Native Token

```python

print(f"Token decimals: {decimals}")
```

**Parameters:**

print(f"Transaction status: {receipt['status']}")
```

**Parameters:**

- `transaction_hash` (HexBytes): Transaction hash.

token_out = "USDC.e"
amount = 1000
slippage = 0.1

route = get_swap_route(chain_in, token_in, chain_out, token_out, amount, slippage)["route"]
```

You can also use the address of the token 

```Python
route = get_swap_route(chains["optimism"], "USDT", chains["arbitrum"], "0xff970a61a04b1ca14834a43f5de4533ebddb5cc8", 1000, 0.1)["route"]

- `amount` (float): Amount to be swapped.
- `slippage` (float): Slippage percentage.

**Resulting Route:**

```commandline
1000 USDT from Optimism to USDC.e on Arbitrum with max slippage of 0.1%
```

### Getting Transaction Estimate

```python
estimate = get_estimate(route)
```

**Parameters:**

- `route` (list): Route obtained from `get_swap_route`.

### Creating the Swap Transaction

```python
swap_txn = create_swap_transaction(sender, route, estimate, client)
```

- `route` (list): Transaction path from `get_swap_route()`.
- `estimate` (dict): Estimate obtained from `get_estimate`.
- `client` (Client, optional): Client object to use the client’s proxy.

### Signing and Sending the Swap Transaction

```python
swap = send_crosscurve_swap_transaction(client, swap_txn, estimate)
```

**Parameters:**

- `client` (Client): Client object to sign the transaction.
- `swap_txn` (dict): Swap transaction created with `create_swap_transaction()`.
