<p class="MsoNormal">Flash loans, as the name suggests, are literally loans that can transpire instantly. Put literally, imagine you could borrow millions of dollars, but you had to pay it all back in just a few seconds? With flash loans, this can be done with absolutely no collateral. Sound too good to be true? </p><p class="MsoNormal">If you are thinking we are a few short sandwiches short of a picnic, allow us to introduce you to the world of flash loans.</p><p>Flash Loans Explained</p><p class="MsoNormal">Flash loans, to put it in simple terms, are loans in which someone can borrow massive amounts of money for free, with the only requirement being that he or she must pay it back almost immediately. </p><p class="MsoNormal">The process is accomplished by employing smart contracts, and their code will have a computer verify if all transactions check out and, of course, whoever is borrowing the money is in condition to pay it back. </p><p class="MsoNormal">So, if you take out a million dollars and repay it in the same transaction, since the initial state is maintained, no one seems to mind, and this is pretty much how flash loans came to be. Flash loans have proven to shore up some obvious weaknesses in traditional loans as well as decentralized finance (DeFi) loans.</p><p class="MsoNormal">By the end of things, if every validation goes through and gets approved, voilà: you have successfully borrowed millions of dollars to do your thing.</p><p>Who Approves Flash Loans?</p><p class="MsoNormal">Naturally, you might be questioning why on earth would anyone want millions of dollars for only a few seconds?</p><p class="MsoNormal">Well, the answer is simple: there’s money to be made. Let’s look at how things were done in the early days and how flash loans can also mean big money.</p><p>Introducing Trading Arbitrage</p><p class="MsoNormal">Trading <a href="https://www.financemagnates.com/terms/a/arbitrage/" target="_blank" id="c297ef24-3074-47a0-a3c1-6f73b43f6594_2" class="terms__main-term">arbitrage</a>, in its simplest form, means: “buy low, sell high.” Literally. The play here is simple. Imagine you could buy something for 1$ and sell it to someone else for 1.5$. If you could repeat the process over and over, you would be making money hand over fist. </p><p>Trading Arbitrage in the World of Bots</p><p class="MsoNormal">Trading arbitrage <a href="https://www.financemagnates.com/tag/arbitrage/">works precisely</a> like that, which is why a few people in the early days of flash loans created automated bots that ran code 24x7 with the purpose of identifying these types of opportunities in the crypto universe and do exactly that: buy low, sell high.</p><p class="MsoNormal">As such, investors cleverly figured out that they could take out a massive loan, buy a ridiculous amount of crypto on one of many platforms out there, and immediately sell it to a different platform, making a few cents or even dollars on each coin sold. </p><p class="MsoNormal">So, now imagine you take a flash loan of 50,000,000$, buy 50,000,000 tokens for a dollar each, and in only a matter of seconds sell them immediately for 51,000,000$. </p><p class="MsoNormal">Well, congrats! You made a cool mil in under a minute (minus the fee, of course). </p><p>Flash Loans Wrap Up</p><p class="MsoNormal">It is now incredibly rare for people to create flash loans which take advantage of trading arbitrage. However, it is still possible, and investors could and should explore it. </p><p class="MsoNormal">Flash loan capabilities allow for many other things, such as collateral swapping, self-liquidation, and so forth. So now the question is: what would you do if you had millions of dollars, even if it was just for a brief moment?</p>
