+This tool allows you to buy meme tokens on the Four.meme platform during the bonding curve phase.
+
+How it works:
+- Tokens are priced on a bonding curve (price increases as more are purchased)
+- You pay with BNB, USDT, WHY, or CAKE
+- 1% trading fee applies (minimum 0.001 BNB equivalent)
+- Once bonding curve hits 100%, liquidity moves to PancakeSwap
+
+Inputs:
+- tokenAddress: The address of the Four.meme token to buy
+- quoteAmount: Amount of quote tokens (BNB/USDT/WHY/CAKE) to spend
+- slippagePercent: Maximum acceptable slippage (default: 1%, range: 0.1-50%)
+
+Returns:
+- Estimated tokens received
+- Trading fee
+- Transaction confirmation
+- Updated bonding curve status
+
+Important Notes:
+- Only works on BNB Chain (Chain ID: 56)
+- Tokens must be in bonding curve phase (not yet listed on PancakeSwap)
+- Price increases with each purchase due to bonding curve
+- For non-BNB quote tokens, you need sufficient token balance
+- Slippage protection prevents unfavorable trades
+
+Example usage:
+"Buy tokens at 0x123... with 1 BNB"
+"Purchase 0x456... using 100 USDT with 2% slippage"

+This tool allows you to sell meme tokens on the Four.meme platform during the bonding curve phase.
+
+How it works:
+- Sell tokens back to the bonding curve
+- Receive BNB, USDT, WHY, or CAKE (depends on token's quote token)
+- Price decreases as more tokens are sold (bonding curve)
+- 1% trading fee applies (minimum 0.001 BNB equivalent)
+
+Inputs:
+- tokenAddress: The address of the Four.meme token to sell
+- tokenAmount: Amount of tokens to sell
+- slippagePercent: Maximum acceptable slippage (default: 1%, range: 0.1-50%)
+
+Returns:
+- Estimated quote tokens received
+- Trading fee
+- Transaction confirmation
+- Updated bonding curve status
+
+Important Notes:
+- Only works on BNB Chain (Chain ID: 56)
+- Tokens must be in bonding curve phase (not yet listed on PancakeSwap)
+- You must hold the tokens you want to sell
+- Token approval required before first sell
+- Price decreases with each sale due to bonding curve
+
+Example usage:
+"Sell 100000 tokens at 0x123..."
+"Sell 50000 of my tokens at 0x456... with 2% slippage"
