Run a flash-loan arbitrage between the course CHEAP and DEAR pools on Base Sepolia using the class wallet's own Arbitrageur contract (profit goes to the class wallet). Use when the boss asks about the flash-loan demo, the CHEAP/DEAR gap, or an arbitrage opportunity there.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Treasury flash-loan arbitrage Wallet and addresses: see **Treasury** in USER.md. ## Contracts - **Use only the class wallet's OWN Arbitrageur** (owner = class wallet) — the profit returns to you. - A "course copy" exists whose owner is the funder: anyone can call `run()`, but the **profit goes to ITS owner**, not you. Never use that one. *(This is exactly the "pay yourself" idea from the Week-3 homework — the profit recipient is fixed in the contract.)* - `run(uint256 borrowUsdc)`: borrow tUSDC from FlashLender → buy MAX on CHEAP → sell MAX on DEAR → repay principal + 0.05% fee → send the rest to the owner. One transaction; if the loan can't be repaid, the whole tx reverts. - Source: `Arbitrageur.sol` (Week-3 flashloan-foundry). CHEAP / DEAR / FlashLender addresses: the Week-3 agents `chain.py`. ## Procedure 1. Read CHEAP and DEAR reserves at the current block. Size the borrow with the course arb formula (swap fee 0.3%, flash fee 0.05%). 2. Report: gap %, borrow amount, flash fee, expected profit in tUSDC, gas estimate in ETH (do not convert to USD without a verified rate), and the profit recipient. **Wait for `confirm`.** …

How to install
mdr add aaron-recompile/ai_finance/treasury-flash-arb@sha256:f87203b15b10cbe1The line at the top of this page pins the label git:20261001.ac53eea, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
