Market Overview
Flash loans represent a specialized segment within decentralized finance that allows users to borrow large sums of cryptocurrency without posting collateral, provided the loan is repaid within the same transaction. This mechanism, first popularized by Aave in 2020, enables arbitrage, collateral swaps, and self-liquidation strategies across decentralized exchanges and lending platforms. The market's valuation reflects the total volume of flash loan activity and the infrastructure value supporting these instant, atomic transactions.
