# @cetusprotocol/zap-sdk

## @cetusprotocol/zap-sdk

The SDK provides a Zap module for specialized liquidity operations with different modes to suit various trading strategies. This module enables users to perform complex liquidity operations with flexibility in how they want to manage their positions.

### Getting Started

### How to Use the Zap SDK ?

#### Installation

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

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

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

#### Setup

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

```typescript
import { CetusZapSDK } from '@cetusprotocol/zap-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 = CetusZapSDK.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 = CetusZapSDK.createSDK({ env })
```

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

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

### 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)
```

if you need to change your rpc url, you can do so as follows:

```typescript
const new_rpc_url = 'YOUR_NEW_FULL_NODE_URL'

sdk.updateFullRpcUrl(new_rpc_url)
```

#### Common Parameters

* `pool_id`: The ID of the liquidity pool
* `tick_lower` & `tick_upper`: Price range boundaries for the position
* `current_sqrt_price`: Current square root price of the pool
* `slippage`: Maximum acceptable price slippage (e.g., 0.01 for 1%)
