Flash Loans

The idea is basically like it's an innovative concept that came out of DeFi. If you have a way where risklessly make a profit, then you could actually get a loan that immediately transact doesn't train. So because they can verifiably know that you can immediately provide return that liquidity through the loan, they'll allow it to happen. The second you get their tokens and you go to the bank and you go redeem those tokens for the total amount of reserves that they have, the flash loan gets immediately paid back.
