一覽

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.

什麼是 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.

❓ 常見問題

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.
