Flash loans let advanced users borrow instantly without collateral and repay within the same transaction. If the loan plus fee isn’t repaid before the transaction ends, everything is canceled automatically.

​
What You Can Do

  • Execute arbitrage or liquidations
  • Swap collateral or refinance positions quickly
  • Move between markets without posting extra capital

​
Basics To Know

  • No collateral needed; repayment happens in the same transaction
  • Supported assets and fees vary by market and liquidity
  • If repayment fails, the transaction reverts (only gas is spent)

​
Where To Find It

Most users won’t need flash loans; they’re mainly for bots, and integrations.
