Flash Swap Combo

We will take a look at the most interesting section of our platform, which is FSC (Flash Swap Combo), the best way to take full advantage of arbitrage in decentralized exchanges with no balance in the wallet. Flash loans can be used to execute the transaction when an arbitrage opportunity is obtained.

What is a Flash loan?

Flash loans are introduced by the Aave, which is an open-source lending protocol for anyone to deposit and borrow crypto assets. Flash loans allow users to borrow large amounts up to the total liquidity available with zero collateral. A Flash loan is a rapid transaction that can be executed when borrow and repayment criteria are satisfied in a single transaction. If the repayment is not done, the whole transaction will be reverted. Anyone can be a crypto whale with a flash loan without any capital.

Use cases:

• Arbitrage trades
• Collateral swap
• Self-hedging
• Self-liquidation
• (Debt) Interest rate swap
• (Debt) Currency swap

The most popular use case by far is Arbitrage trades. For those unfamiliar, arbitrage is the strategy of making a profit from price differences between different markets. To make a significant amount of profit, you will need substantial capital to get started, and this is where the magic happens — We use flash loans to generate free money with no upfront balance.

For arbitrage traders, Premium Block lowers the barriers-to-entry for building money legos, providing all the necessary elements to create arbitrage strategies including the so far coder-only flashloans. But, please keep in mind that Premium Block does NOT find arbitrage opportunities for you. You will have to find it yourself.

Getting started

1) Find an arbitrage opportunity >0.09% to cover the flash loan's fee
2) Have some ETH/BSC in your wallet enough to pay for gas fee

Check the token price for the right opportunities. Token prices are always not the same across all DEXs. When you see the price difference above 0.09% which is the flash loan’s fee, you can set the flash loan amount and create a swap combo by connecting 2 or more DEXs and execute the transaction.

When the transaction gets executed, the final profit will be credited to your wallet address. This way, a successful arbitrage can be done without any capital.

This can save millions of dollars for any project with a high market cap.
