Setup

1. Install dependencies:

   npm install

2. Create .env file:

   BSC_RPC_URL=https://bsc-dataseed.binance.org/
   PRIVATE_KEY=your_private_key_here_without_0x_prefix
   FOUR_MEME_LAUNCHPAD_CONTRACT=0x...  # Launchpad contract address
   TOKEN_ADDRESS=0x...                 # Token you want to buy
   BUY_AMOUNT=0.1                      # Amount in BNB
   

Usage

Find active tokens:

npm run find
# or
npx ts-node findTokens.ts

Check token status:

# Check default token
npm run check

# Check specific token
npx ts-node buyToken.ts check 0xTokenAddress

Buy tokens:

# Buy token with default amount
npm start

# Buy specific token
npx ts-node buyToken.ts 0xTokenAddress

# Buy with custom amount
npx ts-node buyToken.ts 0xTokenAddress 0.5

Sell tokens:

# Sell token with default percentage (100%)
npm run sell

# Sell specific token (100%)
npx ts-node sellToken.ts 0xTokenAddress

# Sell specific percentage
npx ts-node sellToken.ts 0xTokenAddress 50

Contract Address

Find the Four.meme launchpad contract on BSCScan and update FOUR_MEME_LAUNCHPAD_CONTRACT in .env.

Contract ABI

The script now includes the actual Four.meme contract ABI with all buyToken and buyTokenAMAP functions.

Notes

• Uses buyTokenAMAP for precise BNB amount spending
• Make sure you have enough BNB for gas fees
• Test with small amounts first
