In sintesi

Flash loans are uncollateralized loans that must be repaid in the same transaction (1 block, ~13 seconds). Available on Aave, dYdX, others. Practitioners use them for: (1) Arbitrage (borrow 1000 ETH, execute low-risk trade, profit $1k, repay), (2) Liquidations (flash borrow, liquidate over-collateralized position, profit spread), (3) Protocol exploits (flash borrow to manipulate price, extract value). Learning: 4-8 weeks to understand smart contract security and flash loan mechanics. Specialists earn 10-30% premium for finding arbitrage opportunities others miss. High risk: flash loan exploits have cost protocols billions. Only use legally.

Cos'è Flash Loan Opportunity

A flash loan is an uncollateralized loan borrowed and repaid in a single blockchain transaction (13 seconds on Ethereum). Available on Aave, dYdX, and other protocols. Practitioners use flash loans to execute profitable strategies that would be impossible without them. Examples: 1. Arbitrage: Borrow 1000 ETH, buy on Uniswap at $1980, sell on Curve at $2000, repay loan, profit ~$20k.

❓ Domande frequenti

Is flash loan arbitrage legal?
Using flash loans for legitimate arbitrage (profiting from price differences) is legal. Exploiting bugs or using them to manipulate price is not. Gray area: front-running (seeing pending tx, executing before it). Varies by jurisdiction.
What's the typical flash loan profit?
Small: $100-$10k per transaction (low-risk arbitrage). Medium: $10k-$1M (complex strategies, higher risk). Large: $1M+ (protocols exploits, usually illegal/unethical).
What's the main risk with flash loans?
Contract bug = lose all borrowed funds + fees. Example: flash borrow 1000 ETH, code bug, can't repay, transaction fails (but you still pay gas). Always test thoroughly.
How do I find flash loan opportunities?
Monitor DEX prices (Uniswap, Curve), spot price discrepancies. Simulate transaction: would it be profitable after fees? Use bots to detect opportunities continuously.
What's the fee for a flash loan?
Aave: 0.05% (5 ETH on 10k ETH borrowed). dYdX: free (but was exploited, added restrictions). Always factor fee into profit calculation.
