Imagine you could borrow a million dollars instantly and with no collateral. The whole thing would happen anonymously, and you wouldn’t need to assume liability for the loan.
Sounds crazy? That, in a nutshell, is how flash loans work. In the financial demimonde of DeFi they’re perfectly normal and growing in popularity – not least for their facility in making profitable arbitrage trades.

There are some barriers. Technical complexity can be off-putting, and opportunities arise from tiny price differentials. You’ll need knowledge, tools, and the capability to act fast.

Practices unthinkable in traditional finance are a daily reality in DeFi, and for retail traders, that creates opportunities. First launched on the Aave DeFi protocol in 2020, platforms including dYdX, Equalizer Finance, Uniswap, SushiSwap, and DeFiSaver have all moved to offer flash loan capability.
How does flash loan arbitrage work?
Blockchain transactions typically resolve in a few seconds, so the use cases for flash loans must be equally quick. Arbitrage trades are one of the most popular.
Flash loan arbitrage leverages price discrepancies for the same crypto asset across different decentralized exchanges.
