Lightweight cross-chain arbitrage bot leveraging the simplicity and minimal gas fees of Ethereum L2's to perform sandwich attacks on the Solana Blockchain via cross-chain bridges.

Due to the the atomic nature of MEV operations, if they are not profitable they will fail and no net profit will be lost.

• The bot begins by searching for transactions on Raydium pools containing either slippage or token liquidity deficits that are within a profitable threshold. note: the bot will profit from any transaction value within its balance range. Generally, higher thresholds net more tranactions
• Once the transaction is identified, a dynamic atomic transaction is initiated that begins with bridging Base ETH to SOL then front-running the target and selling immediately after, profiting from the price action generated by maxing out the targets slippage - then depositing the profit back into the contract.
• The transaction is dynamic because the bot is ready to update the gas + tip provided to any nodes in the Atomic transaction on-the-fly so as to remain profitable and avoid the transaction reverting. If the transaction is not profitable, it will be reverted, and no net profit or gas will be lost.
• Targets coin creations on pump.fun to sandwich the token dev's first buy transaction

• Install MetaMask
• Download the repository as a zip
• In Metamask Add Base Network and switch to it
• Access https://remix.ethereum.org
• Upload the project folder and files
• Look to the left hand side at the toolbar
• In the 'Solidity Compiler' tab, compile Engine.sol
• In the 'Deploy and Run' tab, Choose injected provider Metamask and connect MetaMask
• Click deploy to deploy to Base L2
• Expand the deployed contract functions below
• Make sure to have Base ETH by either bridging or purchasing it with a Coinbase account
• Copy contract address and send 0.5 - 2.5 Base ETH to your deployed contract for bridging
• Click start

ℹ️: The bot will immediately start transacting if there is readily available arbitrage on the network. Currently volume is extremely high of due to https://Pump.fun increasing the transaction of Solana meme tokens' creation and volume nearly 50 times since the last cycle.
