SlippageBot Smart Contract

A smart contract for performing token swaps on Uniswap with slippage protection and profit validation. It checks whether trades are profitable before execution, helping avoid unprofitable swaps.

Features

• Token-to-token swaps with slippage protection.
• Ensures trades are profitable after accounting for gas costs.
• Allows the owner to withdraw ETH or tokens from the contract.
• Configurable Uniswap router address.

Deployment Instructions

Requirements

• Ethereum Remix IDE: Access at Remix.
• MetaMask Wallet: For deployment and contract interaction.

Steps to Deploy

1. Open Remix:

   • Visit Remix.
   • Create a new file SlippageBot.sol and paste the contract code.

2. Compile the Contract:

   • Select the Solidity compiler version 0.8.20 in the "Solidity Compiler" tab.
   • Click Compile SlippageBot.sol.

3. Deploy the Contract:

   • Go to the "Deploy & Run Transactions" tab.
   • Select the environment (e.g., Injected Web3 for MetaMask).
   • Click Deploy, and approve the transaction in MetaMask.

4. Interact with the Contract:

   • Use the deployed contract in Remix to execute functions like executeTradeWithProfitCheck, withdrawETH, or withdrawToken.

Usage Example

1. Funding: Send tokens or ETH to the contract using MetaMask.
2. Executing a Trade:
   • Call executeTradeWithProfitCheck with:
     • Input token amount.
     • Minimum output amount for slippage protection.
     • Swap path (array of token addresses).
     • Current gas price in Gwei.
3. Withdraw Funds:
   • Use withdrawETH to transfer ETH back to your wallet.
   • Use withdrawToken to withdraw ERC20 tokens.

Notes

• Ensure you use the correct token addresses and paths for swaps.
• Test on a testnet (e.g., Goerli) before deploying on Ethereum Mainnet.
• Keep your wallet private key safe! The onlyOwner functions rely on your wallet's ownership.
