Scan, Simulate & Score Flash Loan Opportunities
FlashLoanLab finds DeFi arbitrage opportunities, runs them through a risk-scoring engine, simulates execution on a mainnet fork, and gates live trading behind strict safety controls. Start in Simulator Mode — no wallet needed.
Every Opportunity Gets a Risk Score
The scoring engine weighs 10 factors — profit, gas, liquidity, slippage, MEV risk, token safety, and more — to give every opportunity a score from 1 to 100.
| Pair | Chain | Strategy | Net Profit | Score |
|---|---|---|---|---|
| USDC → DAI → USDC | BASE | Stable Arb | $312 | 87 |
| USDT → USDC → USDT | ARB | Stable Arb | $798 | 92 |
| WETH → ARB → WETH | ARB | DEX Arb | $524 | 79 |
| USDC → WETH → DAI | BASE | Multi-Hop | $138 | 58 |
| USDC → DEGEN → USDC | BASE | DEX Arb | $14 | 22 |
Built for Safety. Built for Real Use.
FlashLoanLab is not a toy. It's a production-grade DeFi analysis and execution dashboard with simulator-first architecture.
Simulator Mode First
All opportunities are scanned, scored, and simulated against a mainnet fork. No real funds at risk. Learn how flash loans work before touching live markets.
1–100 Risk Score
Every opportunity is scored on 10 weighted factors: net profit, gas efficiency, liquidity depth, slippage, MEV risk, token safety, simulation confidence, and more.
Multi-Layer Safety Gates
Score thresholds, safety limits, re-simulation before execution, wallet confirmation for every trade. The app won't let you execute a bad opportunity.
Manual Live Mode
When ready, enable Manual Live Mode. Every trade requires your explicit wallet approval. Safety limits must be configured first.
Auto Trading (Coming Soon)
Advanced automated execution with a dedicated trading wallet, strict spending limits, daily loss limits, and an emergency stop. Available after extensive simulator testing.

Risk Disclaimer
FlashLoanLab is a tool for analyzing and simulating DeFi opportunities. It does not guarantee profit. Flash loan arbitrage involves significant risk including gas cost overruns, slippage, MEV attacks, smart contract bugs, oracle manipulation, and total loss of funds.
The simulator scores and simulations are estimates based on current market data. Simulated results are not guaranteed to match live execution.
FlashLoanLab is not financial advice. Only use funds you can afford to lose. Do not enable live execution modes without fully understanding DeFi risks.
