market-analysis-automator

Overview The README describes a DeFi flash-loan arbitrage bot called FlashLoanArbitrage. Note that the repository's own description calls it a "market analysis automator," which does not match the documentation provided; the README is the only material supplied and it is written as a first-person hobby project. What it claims to do A local Node.js script, goflash.js, polls ETH/USDC prices on several sources and looks for a price spread. When the spread reaches a stated threshold of 0.9% or more, it calls a smart contract that performs a flash loan, buys ETH on the cheaper venue, sells on the more expensive one, repays the loan and fees, then converts profit back to ETH. The README states the contract takes the loan in USDC and that the user's ETH is only used for gas, not transferred to the contract. Venues and protocols named Price sources: Chainlink (described as the base oracle), Uniswap V2, SushiSwap, Curve Finance and Balancer. Flash-loan providers: Aave, dYdX, Uniswap V3 and Balancer, with per-provider fee and size figures quoted in the text (for example Aave at 0.05% and up to 10,000,000 USDC). These numbers are the author's claims and are not verified anywhere in the repository. Running it Download goflash.js and package.json, run npm install, then node goflash.js. Dependencies listed are ethers, inquirer and chalk. On first launch the script prompts either to create a new wallet or to import one by private key; the key is validated and written to wallet.json in the same folder. A terminal menu then offers DeFi protocol selection, loan amount in ETH, wallet recreation, wallet import, start/stop of arbitrage monitoring and exit. The README describes a price display refreshed roughly every 60 seconds with up/down/unchanged markers, and a troubleshooting section covering module-format errors, invalid key format, insufficient funds for gas, and RPC reconnection. State of the project The documented file listing contains only goflash.js, package.json, wallet.json and README.md, so the smart-contract source and any deployment addresses are not evidenced. There are no tests, no CI configuration and no audit mentioned; the license section simply says the project is shared as-is for educational purposes and used at the user's own risk. The README itself acknowledges that spreads of 0.9% are rare in real markets and that the script "shows a simulated opportunity occasionally for demonstration," which is an important caveat for anyone expecting live results. Risks worth flagging The workflow asks the user to paste a raw private key into a terminal program and stores it in plaintext in wallet.json. Any wallet used this way should be treated as compromised, funded only with what the user is willing to lose and never reused for other assets. Profit figures in the README are illustrative examples rather than measured results, flash-loan arbitrage is competitive and gas-intensive, and nothing here demonstrates that the described contract exists or behaves as documented. Treat the project as an educational sketch and review the code independently before running it. Where it fits As a scripted bot that talks to external services and executes actions on triggers, it is best classified under automation/bots-integrations. Its price-scanning element has a loose analytical flavor, but the code shown is oriented toward trade execution rather than analytics or reporting.
