## Fund Wallet/Account

Ostium has integrated with [Fun.xyz](https://fun.xyz) to provide users with a seamless and intuitive deposit experience.

* If you already hold **USDC on Arbitrum**, simply connect your wallet to start trading. If your funds are in a different wallet, transfer them to the one connected to Ostium.
* **If you’re depositing a different token or from another chain** (e.g., Base, Ethereum Mainnet, Solana, etc.), we recommend using one of the available **Fund Account** options. Fun.xyz will **automatically swap** your token to USDC and **bridge it** to Arbitrum for you.

For more details, refer to the [Fun.xyz documentation](https://docs.fun.xyz).

If you encounter any issues during the deposit process, please reach out directly to the Fun.xyz support team via [Intercom](https://intercom.help/funxyz/en/articles/10732578-contact-us). They’ll be best equipped to assist you.

### Transfer Crypto

1. **Pick your deposit asset:** From the “Select token” dropdown, choose the cryptocurrency you want to convert into Arbitrum-USDC.
2. **Choose your source network:** Use the “Select chain” dropdown to select the EVM chain (or Solana) where your token currently resides.
3. **Copy your unique deposit address:** Click the “Copy address” icon (do **not** reuse the example shown here).
4. **Send your tokens:** In your wallet, transfer the chosen token on the selected chain to that copied address. Ensure the USD value of your transfer meets or exceeds the minimum deposit threshold. Remember that on-chain gas fees still apply on the source network.
5. **Watch your balance update**\
   Within a few minutes, your Arbitrum-USDC balance (top-right of the app) will reflect the dollar value of your deposit, minus any swap fee.

## 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://ostium-labs.gitbook.io/ostium-docs/ostium-trading-engine/step-by-step-tutorial/fund-wallet-account.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.
