# Simulating Flash Loans ## Contents [Overview](#overview) | [Prerequisites](#prerequisites) | [Instructions](#instructions) | [Output](#output) | [Error Handling](#error-handling) | [Examples](#examples) | [Resources](#resources) ## Overview Simulate flash loan strategies across Aave V3, dYdX, and Balancer with profitability calculations, gas cost estimation, and risk assessment. Evaluate flash loan opportunities without executing real transactions. ## Prerequisites 1. Install Python 3.9+ with `web3`, `httpx`, and `rich` packages 2. Configure RPC endpoint access (free public RPCs via https://chainlist.org work fine) 3. Optionally add Etherscan API key for better gas estimates 4. Set RPC in `${CLAUDE_SKILL_DIR}/config/settings.yaml` or use `ETH_RPC_URL` env var ## Instructions 1. Simulate a two-DEX arbitrage with automatic fee and gas calculation: ```bash python ${CLAUDE_SKILL_DIR}/scripts/flash_simulator.py arbitrage ETH USDC 100 \ --dex-buy uniswap --dex-sell sushiswap ``` 2. Compare flash loan providers to find the cheapest for your strategy: ```bash python ${CLAUDE_SKILL_DIR}/scripts/flash_simulator.py arbitrage ETH USDC 100 --compare-providers ``` 3. Analyze liquidation profitability on lending protocols: ```bash python ${CLAUDE_SKILL_DIR}/scripts/flash_simulator.py liquidation \ --protocol aave --health-factor 0.95 ``` 4. Simulate triangular arbitrage with multi-hop circular paths: ```bash python ${CLAUDE_SKILL_DIR}/scr...
