# Quickstart Guides

Participating in a launch on the Bio Protocol is a straightforward process designed to be fair, transparent, and community-driven. This guide will walk you through the key steps, from preparing for the sale to understanding how to engage with the project post-launch.

This section contains the following guides:

* [**Buying Bio Ecosystem Tokens**](https://docs.bio.xyz/bio/descientists/quickstart-guides/buy-bio-ecosystem-tokens):  A step-by-step guide to acquiring tokens in the Bio ecosystem using fiat currency (USD, EUR etc.).
* [**Funding Your Participation**](https://docs.bio.xyz/bio/descientists/quickstart-guides/fund): A step-by-step guide to acquiring and committing the `$USDC` needed to invest in a project.
* [**How to Stake $BIO**](https://docs.bio.xyz/bio/descientists/quickstart-guides/bio-staking-guide): Learn how to stake/unstake $BIO.
* [**How to Bridge $BIO**](https://docs.bio.xyz/bio/descientists/quickstart-guides/bridge-bio): Instructions on how to move your `$BIO` tokens to the Base network to participate in launches.
* [**Providing Liquidity Post-Launch**](https://docs.bio.xyz/bio/descientists/quickstart-guides/provide-liquidity): Learn how to support a project's long-term health by providing additional liquidity after the initial launch.

## The Ignition Sale Model

All projects on Bio Protocol V2 currently launch through a **Ignition sale**. This means the price per token is set from the beginning, creating a predictable and clear process for everyone.

* **Denomination:** All sales are denominated in `$USDC`.
* **Success Condition:** A launch is only successful if the total amount of `$USDC` committed by the community meets or exceeds the project's funding goal. If the goal isn't met, all participants are fully refunded.

## How to Participate: A Two-Step Process

To join a sale, you need to complete two key actions:

1. **Commit $USDC:** You must commit the amount of `$USDC` you wish to invest.
2. **Pledge BioXP:** You can optionally spend your accumulated [BioXP points](https://docs.bio.xyz/bio/introduction/bio-protocol-v2/staking-and-vebio/bioxp) to secure the right to an allocation. If a sale is subscribed, higher BioXP = larger allocation priority. BioXP is earned by contributing to the ecosystem, such as by staking `$BIO`.

Your final allocation of the project's tokens is determined by the number of BioXP points you pledge relative to the total points pledged by all other participants. Over-pledging increases your chances of obtaining the max allocation (1% of the total supply).

## Understanding Your Allocation

Launches are often oversubscribed, meaning the community commits more USDC than the project's target. In this case, your final allocation is calculated pro-rata based on your share of the total BioXP pledged, up to a maximum cap.

The final allocation is determined by the following formula:

`user_allocation = min((user_points / total_points_pledged) * tokens_for_sale, 0.005 * tokens_for_sale)`

Where:

* `user_points` is the amount of BioXP you pledged.
* `total_points_pledged` is the total BioXP pledged by all participants.
* `tokens_for_sale` is the total number of tokens available in the launch.

**Key Rules:**

* **Max Allocation:** To ensure fair distribution, no single user can purchase more than 1**%** of the total token supply being sold.
* **Refunds:** If you commit more `$USDC` than your final allocation allows, the excess `$USDC` and any unused BioXP are automatically returned to you.
