# Configuration

Initialize the **Arweave Data Storage SDK** object with various configuration options. The `appName` is recommended as it helps in organizing and searching your transactions on Arweave. The `privateKey` can either be your account’s key or a flag to use a browser wallet. Other parameters like `network`, `token`, and `gateway` let you tailor the SDK to your specific environment.

```
const { Configuration, Network, Token} = require('arweave-storage-sdk');

const config = new Configuration({
	appName: 'My cool project'
	privateKey: process.env.PRIVATE_KEY,
	network: Network.BASE_MAINNET,
	token: Token.USDC
})
```

| Option       | Optional | Description                                                                                                                                          |
| ------------ | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| `appName`    | true     | App name to be used in Arweave transactions. Recommended to use since it makes searching all your app files easier.                                  |
| `privateKey` | false    | Private key of your account. JWK in case of Arweave. if `'use_web_wallet'` is used, sdk will rely on browser wallets.                                |
| `network`    | true     | Network of your payment token. Eg: 'SOL\_MAINNET'. Simply use the Network object provided by the sdk to see supported networks. Defaults to Arweave. |
| `token`      | true     | Token to use for payments. Eg: 'USDT'. Use the Token object provided by the sdk to see all supported tokens. Defaults to AR.                         |

* **Encryption:** For private drives or file storage, use the built-in Crypto utilities to manage encryption.
* **API Calls:** The SDK uses the ArFSApi internally to interact with the Arweave network. You can override or customize gateway endpoints if needed.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.arweavekit.com/configuration.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
