# @cetusprotocol/limit-sdk

**Cetus Limit Order SDK** is a powerful tool that enables developers to integrate **limit order trading functionality** into their applications. With this SDK, users can place orders at a specific price, ensuring more control over their trades compared to market orders.

### Getting Started

### How to Use the Limit SDK ?

#### Installation

To start using the `Limit SDK`, you first need to install it in your TypeScript project:

npm link: <https://www.npmjs.com/package/@cetusprotocol/limit-sdk>

```bash
npm install @cetusprotocol/limit-sdk
```

#### Setup

Import the SDK into the TypeScript file where you intend to use it:

```typescript
import { CetusLimitSDK } from '@cetusprotocol/limit-sdk'
```

#### Initializing the SDK

Initialize the SDK with the required configuration parameters. This typically includes setting up the network and API keys, if needed.

If you would like to use the mainnet network and the official Sui rpc url, you can do so as follows:

```typescript
const sdk = CetusLimitSDK.createSDK()
```

If you wish to set your own full node URL or network (You have the option to select either 'mainnet' or 'testnet' for the network), you can do so as follows:

```typescript
const env = 'mainnet'
const full_rpc_url = 'YOUR_FULL_NODE_URL'
const wallet = 'YOUR_WALLET_ADDRESS'

const sdk = CetusLimitSDK.createSDK({ env })
```

If you wish to set your own full node URL or SuiClient, you can do so as follows:

```typescript
const sdk = CetusLimitSDK.createSDK({ env, sui_client })
// or
const sdk = CetusLimitSDK.createSDK({ env, full_rpc_url })
```

### Features & Usage

After linking your wallet, if you need use your wallet address to do something, you should set it by `sdk.setSenderAddress`.

```typescript
const wallet = 'YOUR_WALLET_ADDRESS'

sdk.setSenderAddress(wallet)
```
