# Join Ignition Sales

Once you understand the basics of launch participation, the next step is to prepare your assets. This page outlines the process of acquiring and committing the `$BIO` needed to invest in a project.

## Step 1: Acquire $BIO

All sales on the Bio Protocol are denominated in `BIO`. If you don't already hold `BIO`, you will need to acquire it from an exchange where it is traded.

### From a Centralized Exchange (CEX)

For many users, the simplest way to acquire `BIO` is through a major centralized exchange. `BIO` is available for spot trading on exchanges like:

* Coinbase Wallet
* Binance

To purchase, you will need to create an account, deposit funds, and place an order for `BIO`. Once purchased, you must withdraw your `BIO` to a personal wallet on a supported network (like Ethereum or Base) to use it in the Bio Protocol.

### From a Decentralized Exchange (DEX)

If you prefer to use a decentralized exchange, you can acquire `$BIO` by swapping other cryptocurrencies for it on a platform like [Uniswap](https://uniswap.org/).

* **Official Token Addresses:** Find the official contract addresses for `$BIO` on all supported networks in our [Basic Token Information](/bio/~/changes/216/introduction/bio-token/basic-token-information.md) document.

To protect yourself from scams, always verify that you are interacting with the correct token contract address before purchasing `$BIO` on a decentralized exchange.

Ensure you have enough `$BIO` in your wallet to cover both the amount you wish to commit to the sale and the amount you plan to pledge to get BioXP.

## Step 2: Bridge to Base (If Necessary)

The Bio Protocol operates primarily on the **Base** network. If your `BIO` is on another blockchain (like Ethereum Mainnet), you will need to bridge it over to Base to participate in launches.

For detailed instructions, see the next page:

* [**How to Bridge $BIO**](/bio/~/changes/216/descientists/quickstart-guides/bridge-bio.md)

## Step 3: Commit Your BIO

During the active launch period (typically 2-3 days), you can commit your `$BIO` directly on the project's launch page.

1. **Navigate to the Launchpad:** Go to the [Bio Protocol Launchpad](https://app.bio.xyz/launchpad).
2. **Select the Project:** Choose the project you wish to contribute to.
3. **Pledge and Commit:** On the project page, you will find the interface to:
   * Pledge your desired amount of BioXP.
   * Commit your desired amount of `BIO`.

4. **Confirm the Transaction:** Sign the transaction in your wallet to finalize your commitment.

Your `BIO` and pledged BioXP are now locked until the sale concludes. If the launch is successful, you will be able to claim your new project tokens. If not, your assets will be available for withdrawal.

## 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://docs.bio.xyz/bio/~/changes/216/descientists/quickstart-guides/fund.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.
