🤔 What is a Flash Loan?

A flash loan is a type of cryptocurrency loan that is borrowed and repaid within the same blockchain transaction. Key features:

No collateral required
Must be borrowed and repaid in one transaction
Typically used for arbitrage or refinancing
High risk, high potential reward
5% dev tax applied to all flash loans
