Solana-Pumpfun-Smart-Contract

This is the Pump.fun smart contract developed using Rust and Anchor.

Clone Project

   git clone https://github.com/derricklee918/Sol-Pumpfun-Contract.git
   cd Sol-Pumpfun-Contract
   npm install

Features

It has All features that pump.fun has.

  • Token Mint

  • Create Pool with 30 Sol of initial virtual Sol reserve

  • Add Liquidity

  • Swap Token with the price of the token (Virtual Sol Reserve / Virtual Token Reserve)

  • Raydium Launch when the Market Cap of the Token (price of the token * 10 ** 9) is reached to $69M

When the Market Cap meet the KOH, the pumpfun launch the real Sol $12K i.e. $24K Liquidity to the Raydium. Then the rest of the liquidity will be gained by pumpfun team.

Bonding Curve Logic

It is using its own specific bonding curve logic.

so It is

X * Y = K ** 2

X : the price of the token

Y : the supply of the token in the pool

It has its own test cases to test all functions except Raydium Launch because it is used my ongoing project. You can check the tx to Remove vitual LP and Create Raydium Pool in this smart contract with CPI calls. https://explorer.solana.com/tx/4L6MWmtV1ZsT8NFfbtu68ZYyYVbpvZ4iynJhPdZw8jESi28TxwojjTFs88Q5QRdNUb297aWfkKcoYP9Ya8npx8AV?cluster=devnet In this smart contract, I set creating LP FEE as 5% of Reserves.
