crypto-sentinel-bot

The README is written in English and titles the project FlashLoanArbitrage, even though the repository is named crypto-sentinel-bot with the description 'Monitors crypto market conditions in real-time.' The document describes a DeFi flash-loan arbitrage bot that runs locally as a Node.js script named goflash.js and interacts with a smart contract. The stated workflow is: the contract takes a USDC flash loan, converts the user's ETH to USDC before the deal, buys ETH at a lower price on one platform, sells ETH at a higher price on another, repays the loan and associated fees and gas, converts remaining profit from USDC back to ETH, and leaves the net profit in ETH. However, the README does not include the smart contract source code, a verified contract address, or deployment instructions. The local script monitors ETH/USDC prices on five sources: Chainlink as an oracle for the base price, Uniswap V2, SushiSwap, Curve Finance, and Balancer. It checks prices every 60 seconds and waits for a price difference of 0.9% or more before triggering arbitrage. It displays real-time prices with up/down/unchanged indicators. For flash loans, it lists four protocols with fee and liquidity claims: Aave (0.05%, up to 10,000,000 USDC), dYdX (0.05%, up to 500,000 USDC), Uniswap V3 (0.01%, up to 5,000,000 USDC), and Balancer (0.02%, up to 1,000,000 USDC). The README recommends dYdX or Uniswap V3 for lower fees and cautions that larger loans incur higher fees. Setup instructions: download goflash.js and package.json, place them in a folder, run npm install, then node goflash.js. On first launch, the user chooses to create a new wallet or import an existing wallet by private key. The generated or imported private key is saved to wallet.json in the same folder. The menu offers DeFi protocol selection, loan amount in ETH from 10 up to the protocol maximum, recreate wallet, import wallet by private key, start arbitrage, and exit. The README warns that loans over 10 ETH need at least 0.1 ETH for gas, lists trading fees of 0.1%, slippage of 0.05%, and gas, and says the script scans every 60 seconds and triggers arbitrage automatically. Key caveats and security notes: the README states it is shared as-is for educational purposes and use is at the user's own risk. It says real markets rarely provide the required 0.9% price difference and that the script occasionally shows a simulated opportunity for demonstration. It repeatedly instructs users to protect wallet.json and private keys, use a dedicated wallet, start with small amounts, and add wallet.json to .gitignore. The document's dependencies are ethers ^6.11.1, inquirer ^8.2.6, and chalk ^4.1.2. Project structure lists goflash.js, package.json, wallet.json (auto-generated), and README.md. Troubleshooting items cover module format errors, private key format, insufficient funds, zero wallet balance, RPC reconnection, missing Uniswap V2 pairs, and failure to find arbitrage opportunities. Independent assessment based only on the README: this is an interactive CLI tool for monitoring crypto prices and optionally executing flash-loan arbitrage, but the repository material provided does not evidence a working, audited, or profitable system. The absence of smart contract code and deployment details, the mismatch between repository name/description and README title, the request to create or import a private key into wallet.json, and the admission of simulated opportunities are notable risk indicators. The README itself frames the project as educational.
