# Fair launch mechanism across different chains starting with Solana
A Solana smart contract implementing customizable bonding curves with fee distribution and liquidity management capabilities.
## Overview
This smart contract implements an launchpad using bonding curves. It supports multiple curve types, fee collection and distribution, and liquidity management features.
-> Fair launch mechanism with fully customizable business logic
## Features
### Bonding Curve Types
- **Linear Curve**: Price increases linearly with supply
- **Quadratic Curve**: Price increases quadratically with supply
### Core Functionality
1. **Buy Tokens**
- Calculate token price based on selected curve type
- Apply fees
- Update reserves and supply
- Distribute fees to configured recipients
2. **Sell Tokens**
- Calculate token value based on selected curve type
- Apply fees
- Update reserves and supply
- Distribute fees to configured recipients
3. **Liquidity Management**
- Add liquidity with configurable lock periods
- Remove liquidity after lock period expires
### Fee Management
- Configurable fee percentage (basis points)
- Multiple fee recipients with customizable share ratios
- Claimable accumulated fees for recipients
### Governance
## How to test
1. Install
```
yarn install
```
2. Add your private key in the config folder
2.1 Signer on `~/.config/solana/id.json` (default signer for anchor config)
2.2 Fee Recipient on `~/.config/solana/id2.json` and `~/.config/solana/id3.json`
3. Run script to create token
Noted: Fill the `SIGNER_PRIVATE_KEY` and `USER_PRIVATE_KEY` in the `.env` file
```
yarn create-token
```
Result

```
4. Run tests
Noted: Replace your mint account in the `tests/bonding-curve.ts` file
```js
const mint = new PublicKey("3YChZhQqYpriRAiNunKLRxF5jnTuj97RE4SHBBHNAJsu");
```
Run test
