Trading is a fast-paced and rapid environment. This is especially true in the crypto world, where assets can fluctuate in just a few minutes. Traditional financial solutions cannot keep up with the growing needs of this market. Thus, new innovations in decentralised finance (DeFi) fill the gap. One such feature is known as a DeFi flash loan.
What is a Flash Loan?
A flash loan is a new type of unsecured loan where the borrower receives funds, uses them productively and returns them instantaneously. This is different from standard loans where borrowers must provide documents and collateral, and then repay the loan over a longer period.
How Do Flash Loans Work
Like many other DeFi features, flash loans are based on smart contracts. Smart contracts are tools on a blockchain that automatically perform an action when the conditions are met. A flash loan’s condition is that the borrower repays the loan within the same transaction. If this does not happen, the loan is reversed instantly.
As mentioned above, flash loans do not require collateral and are completed instantaneously. This is unique and cannot be replicated through traditional means.
Advantages of DeFi Flash Loans
Proponents of flash loans consider them one of the most important innovations in the DeFi space. Here are some of the reasons flash loans are popular.
- No Collateral – As an investor, it is easy to acquire flash loans as you do not need to hold crypto as collateral. You are not at risk of losing your funds through flash loans.
- Instantaneous – Flash loans provide you with quick access to liquidity. This cannot be matched by traditional loan facilities, thus making flash loans unique.
Examples of DeFi Flash Loan Use Cases
How to make money with flash loans?: There are many ways to use flash loans in your investments.
- Arbitrage – Arbitrage trading involves taking advantage of the price difference of the same asset on two different exchanges. Suppose a crypto token AB Coin is priced at $10 on exchange X and $11 on exchange Y. By buying it from X and instantly selling on Y, you can earn a profit of $1 per token. Flash loans can provide you instant liquidity to perform these trades.
- Collateral Swap – If you have another collateralized DeFi loan, flash loans can help you swap the collateral for some other form of collateral.
- Transaction Fees – Flash loans perform several transactions in one. They thus consolidate the transaction fee to be lower than performing each action separately.
Risks and Limitations of Flash Loans
Smart Contract Vulnerabilities
Since flash loans operate through smart contracts, any flaws or vulnerabilities in their programming can risk their functioning. If the transaction is not done seamlessly, it can reduce the possible investments you can undertake.
Flash Loan Attacks
Flash loans have one major shortcoming that hackers and malicious actors exploit. These are known as flash loan attacks. They use flaws in the smart contract to trick lenders into believing the loan has been repaid, even if it has not. This has led to the theft of large sums of money in the past.
