volume-monitor-bot

This repository is presented in its README under the name FlashLoanArbitrage, described by the author as a DeFi arbitrage bot that combines an on-chain smart contract with a local Node.js script, goflash.js, run on the user's own computer. Note that the repository name (volume-monitor-bot) and its short description about tracking trading volume across DEX platforms do not match the README content, which is about arbitrage rather than volume tracking; the README never describes volume-monitoring functionality. What the README says the software does: - Runs an interactive command-line application started with node goflash.js after npm install. - On first launch it prompts the user to either create a new wallet or import an existing one by private key. The key is validated (must start with 0x) and stored in wallet.json in the project folder, and the wallet address and balance are shown in the menu. - The main menu offers: choosing a DeFi protocol, setting the loan amount in ETH, recreating the wallet, importing another wallet, starting arbitrage, and exiting. - During monitoring, the script polls ETH/USDC prices on a 60-second cycle and displays them with up/down/unchanged indicators plus the current maximum spread. - The claimed price sources are Chainlink (used as a base oracle), Uniswap V2, SushiSwap, Curve Finance and Balancer. The README states that an arbitrage is only triggered when the spread is 0.9% or more, and that the script is intended to convert ETH to USDC before a trade and profit back into ETH afterwards. - The README lists four protocols as flash-loan sources with the author's stated fee and liquidity figures: 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). These numbers are the author's claims and are not verified in the README. - Dependencies are listed as ethers ^6.11.1, inquirer ^8.2.6 and chalk ^4.1.2, indicating Ethereum interaction plus an interactive colored CLI. Caveats and gaps worth knowing: - The README repeatedly describes a smart contract performing the flash loan, swaps and repayment, but the documented project structure lists only goflash.js, package.json, wallet.json and README.md, so the contract source is not shown in the described layout. - The troubleshooting section states that a 0.9% spread is rare in real markets, that the script will therefore often find no opportunity, and that it will "show a simulated opportunity occasionally for demonstration". Readers should treat any displayed profit as potentially simulated rather than realized. - All profit examples, fee percentages (0.1% trading, 0.05% slippage) and outcomes come from the author; nothing in the README provides evidence, benchmarks or an independent audit. - The setup stores a raw private key in a plaintext wallet.json file; the README itself advises never sharing it, adding it to .gitignore, keeping offline backups, using a dedicated wallet, and starting with small amounts. Handling private keys this way carries serious risk of fund loss. - The project is stated to be shared as-is for educational purposes, with use at the user's own risk, and the license section gives no specific license. The README's structure is reasonably complete for a hobby CLI bot: how it works, protocol list, scanned platforms, step-by-step run instructions, menu explanations, a worked example, a sample price-monitoring display, troubleshooting entries and security tips. However, given the mismatch between the repository metadata and the README, the absence of visible contract code in the described layout, the admitted simulated opportunities, and the required private-key handling, prospective users should treat it as an unverified educational script rather than a dependable trading tool.
