When you execute a profitable arbitrage, you are exploiting markets inefficiencies. As the crypto markets and especially DEXs are still in its infancy, you can benefit from its inherent volatility and fragmentation.

FlashSwap makes it easy to maximize the profit achieved through arbitrage thanks to uncollateralized flash loans which will make the smaller profit percentage much greater. All while paying back the flash loan in the exact same transaction.

Profits are paid out to your connected wallet once all the trades are confirmed on the blockchain and your loan terms are completed. This can usually be anywhere between a few minutes to 30 minutes depending on network congestion.


If you still do not see your profits after executing the arbitrage and waiting a while, you may have entered an incorrect token address/symbol or the gas fees were not sufficient.


Try again with the same amount of GAS Fees or slightly more to ensure the trades all complete successfully. Remember, the way the bot works is by executing multiple trades within miliseconds of each other so the initial gas fees must be high enough to make sure the transactions are all completed in time for the loan to be paid back and profits to be made.
