This project is more or less a copy of https://github.com/bilix-software/solana-pump-fun. I made a npm package out of it and resturctured/refactored the code a little bit.

Do not use your main wallet with this script! Always use a trading wallet with your trading budget. Don't be lazy! Create a wallet for this now!
Solan Pump.fun Trader is a library to execute buy and sell orders for SPL tokens that were created on pump.fun.
Just install it with npm or yarn or whatever.
npm install "@degenfrends/solana-pumpfun-trader"import PumpFunTrader from '@degenfrends/solana-pumpfun-trader';
const pumpFunTrader = new PumpFunTrader();
this.pumpFunTrader.setSolanaRpcUrl('https://yoursolanarpc.com');
await this.pumpFunTrader.buy(
privateKey: '12123423434234', // your private key
tokenAddress: 'ejddjsldjsdlks', // the address of the token you want to buy
amount: 0.5, // amount in solana
priorityFee: 0, // (optional) you should increase the priority fee when you want to make sure that transactions are always succesfull.
slippage: 0.25, // (optional) 0.25 equals 25% slippage.
isSimulation: false // (optional)
);
await this.pumpFunTrader.sell(
privateKey: '12123423434234', // your private key
tokenAddress: 'ejddjsldjsdlks', // the address of the token you want to sell
tokenBalance: 10000000 // the amounts of token you want to sell, you need to multiply the amount you want to sell by 1000000 since pump.fun tokens have 6 digits,
priorityFee: 0, // (optional) you should increase the priority fee when you want to make sure that transactions are always succesfull.
slippage: 0.25, // (optional) 0.25 equals 25% slippage.
isSimulation: false // (optional)
);There are functions to build sell and buy transaction instructions too, which you can use to bundle transactions.
