FAQ

Frequently asked questions about VAEA Flash.

What is a flash loan?

A flash loan lets you borrow tokens without collateral, as long as you repay within the same transaction. If repayment fails, the entire transaction reverts — you never received the tokens. The only cost on failure is the base TX fee (~0.000005 SOL).
