This tool allows users can detect new migration from four.meme to PancakeSwap. It can be used for migration sniping if we integrate pancake swap.

Required:

• PRIVATE_KEY - Your wallet private key
• SNIPER_CONTRACT_ADDRESS - Your sniper contract address
• WS_PROVIDER_URL - WebSocket provider URL for event monitoring
• RPC_PROVIDER_URL - RPC provider URL for transactions
• SEND_BNB - Amount of BNB to send per trade (e.g., "0.0005")

Optional:

• TOKEN_NAME_CONTAINS - Filter out tokens by name (see Token Filtering section)
• MIN_LIQUIDITY_BNB - Minimum liquidity filter (see Liquidity Filtering section)

You can filter out tokens by name before buying. Add this to your .env file:

• TOKEN_NAME_CONTAINS - Tokens with names containing these strings will be SKIPPED (case-insensitive)
  • Multiple keywords can be separated by commas
  • The bot will SKIP tokens if the name contains ANY of the specified keywords
  • The bot will BUY all other tokens that don't match the filter

Examples:

# Skip tokens where name contains "Moon" (buy everything else)
TOKEN_NAME_CONTAINS=Moon

# Skip tokens where name contains "Moon" OR "DOGE" OR "Pepe" (buy everything else)
TOKEN_NAME_CONTAINS=Moon,DOGE,Pepe

# Skip tokens where name contains "Safe" OR "Moon" OR "Rocket" (buy everything else)
TOKEN_NAME_CONTAINS=Safe,Moon,Rocket

Note:

• If TOKEN_NAME_CONTAINS is not set or empty, the bot will buy all detected tokens
• Filtering is case-insensitive
• Keywords are separated by commas (spaces around commas are automatically trimmed)
• This is a blacklist filter - tokens matching the keywords are excluded

You can filter tokens by minimum liquidity before buying. Add this to your .env file:

• MIN_LIQUIDITY_BNB - Minimum total liquidity required in BNB (e.g., "1.0" for 1 BNB minimum)
  • Pools with less liquidity than this will be skipped
  • Total liquidity = 2 × WBNB reserve (since AMM pools maintain equal value on both sides)

Examples:

# Only buy tokens with at least 1 BNB total liquidity
MIN_LIQUIDITY_BNB=1.0

# Only buy tokens with at least 5 BNB total liquidity
MIN_LIQUIDITY_BNB=5.0

# Only buy tokens with at least 0.5 BNB total liquidity
MIN_LIQUIDITY_BNB=0.5

Note:

• If MIN_LIQUIDITY_BNB is not set or 0, liquidity filtering is disabled
• The bot calculates total liquidity as 2 × WBNB reserve
• This helps avoid low-liquidity tokens that may be rug pulls or have high slippage
