Welcome to the Pumpfun Solana Smart Contract repository. This repository contains the Rust/Anchor-based smart contract powering the Pumpfun ecosystem. Designed with robust features and innovative logic, this contract is built to manage token minting, liquidity pools, token swaps, and market cap-based launches on Raydium. If you have any questions or need support, feel free to reach out, and we can discuss the best way to assist you.
The contract includes all the advanced features that define the Pumpfun platform:
✅ Token Minting Seamlessly mint Pumpfun tokens to kickstart your liquidity pool.
✅ Create Liquidity Pools Establish a pool with an initial 30 SOL virtual reserve, creating a strong foundation for token transactions.
✅ Add Liquidity Contribute liquidity to grow the pool and enhance token marketability.
✅ Token Swapping
Facilitates token swaps based on a dynamic bonding curve price, calculated as:
Price = Virtual SOL Reserve / Virtual Token Reserve.
✅ Raydium Launch Integration
Automatically launch on Raydium when the token’s market cap (price × 10⁹) reaches $69M. At launch:
- $12K in SOL ($24K total liquidity) is added to Raydium.
- Remaining liquidity reserves are allocated to the Pumpfun team for platform growth.
The contract uses a custom bonding curve mechanism defined by:
X × Y = K²
- X: Token price.
- Y: Token supply in the pool. This ensures a dynamic and balanced liquidity model tailored to Pumpfun’s tokenomics.
The contract includes comprehensive test cases to validate functionality, covering all features except Raydium Launch (which integrates with the ongoing project).
- Remove Virtual LP and Create Raydium Pool:
- A 5% reserve fee applies when creating LPs, ensuring sustainable liquidity pool growth.
By leveraging this smart contract, you gain access to a cutting-edge decentralized financial ecosystem tailored for scalability, efficiency, and innovation. It’s the ideal solution for managing tokens and liquidity in a dynamic market environment.
