# @cetusprotocol/dca-sdk

**DCA (Dollar-Cost Averaging)** is an efficient and low-risk investment strategy, particularly suitable for markets with high volatility. By using the **DCA SDK**, developers can easily integrate this strategy into their applications, helping users achieve long-term, stable investment growth. Through automation and regular investments, the **DCA SDK** helps users reduce the impact of short-term market fluctuations, leading to better investment outcomes.

### Getting Started

### How to Use the Dca SDK ?

#### Installation

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

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

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

#### Setup

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

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

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

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

### Features & Usage

After linking your wallet, you need to set it by `sdk.setSenderAddress`.

```typescript
const wallet = 'YOUR_WALLET_ADDRESS'

sdk.setSenderAddress(wallet)
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cetus-1.gitbook.io/cetus-developer-docs/developer/via-sdk-v2/sdk-modules/cetusprotocol-dca-sdk.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
