Create an Aave Flash Loan arbitrage smart contract from scratch in this comprehensive flash loan tutorial. In this step-by-step DeFi tutorial we use the Aave v3 protocol to build a flash loan receiver smart contract. We'll then use a mock DEX contract to simulate a flash loan arbitrage.

Bro please don't stop making content. Your tutorials are some of the most easily digestible Solidity Tutorials online hands down. Even when I run into issue it's easy to fix because the foundation of how you deliver the information is solid. I'm not a complete novice when it comes to solidity but I'm also not an expert. My point is these are good for people of all levels even those who want to understand the code just so they now a little about how smart contracts work. Please don't stop making these videos they're awesome. If you're not gonna do this here on youtube at least start a Udemy class or something. Key point being your work is needed in this space.

I made an cross exchange arbitrage bot with flash loan. What no one tells you, is that miners who land the block have control over the transactions that will go on the block. So they can manipulate who will take the arbitrage oportunities.

@JS-jq8pu Жыл бұрын

any tips to start creating a cross exchange arbitrage bot with flashloans?

@pfaq Жыл бұрын

@@JS-jq8pu there's no shortcuts, you can look for degenbot to have some idea if you understand python. the concept is basically keep track of current reservers of a pair and calculate the future by filtering pending transactions on the blockchain> You will also need code in solidity, there's no way to run (but is not as hard as it looks, honestly is the easiest part). I have nothing linked with degenbot, it's just the only arbitrage real content i ever saw in the internet, and i still not use it, i made all my stuff. It's a lot of work (for real, there's no limit to upgrade), as more exchanges you implement more opportunities and also more profitable each opportunity will be, so it's kinda exponential. I don't know what more i can tell you, ask me a more specific question if u want. Currently im making just few dollars a day, probably an average of 5-6. But is increasing as i upgrade my code. January was few cents a day

No that wasn't really the intention in this video - the flash loan was just from smart contract to Aave and back. There is a withdraw function in the contract though were the wallet owner could ultimately withdraw the funds from, after the completion of the flash loan. But yes, that does work. If you did want the funds to go back to the wallet automatically, you could implement a transfer from smart contract to wallet at the conclusion of the flash loan.

Hi Sir, At 15:34 secs, I didn't understand 1.How, why inserted you IpoolAdressesProvider(_addressProvider) into FlashLoanSimpleReceiverBase() ? How are they interlinked if I am right? 2. What is 'IpoolAdressesProvider' in return type of "function ADDRESSES_PROVIDER() external view returns (IPoolAddressesProvider)" Thank you sir.

@BlockExplorerMedia Жыл бұрын

1. 'IFlashLoanSimpleReceiver' is the basic interface that needs to be implementer in order for 'FlashLoanArbitrage.sol' to be a receiver of a flash loan. So we need to implement 'executeOperation', 'ADDRESSES_PROVIDER' and 'POOL' from 'IFlashLoanSimpleReceiver'. 'FlashLoanSimpleReceiverBase' implements 'ADDRESSES_PROVIDER' and 'POOL'. 'FlashLoanArbitrage.sol' inherits 'FlashLoanSimpleReceiverBase' and also implements 'executeOperation'. It makes sense to organize the code in this way since the implementations of 'ADDRESSES_PROVIDER' and 'POOL' don't change, but 'executeOperation' contains custom logic specific to our smart contact. 2). 'IpoolAdressesProvider' is just an abstraction layer that returns a pool address. It provides flexibility in the case that the address were to change (so we don't have to hardcode it).

I have a question. I notice at the beginning when you ran the aave packages with the dotenv package, the env package populated. When I ran the aave packages with the dotenv package, it didn't populate. Anyone know why that is?

.env files are private files that hold secret information so they don’t get committed to repos. I checked the GitHub project and there is a .env.example so you could just clone the repo and rename the .env.example file to just .env

Hi sir, in the last step, around 47 mins, we didn't use excuteOperation. Then who initiated deposit, buy, sell function in it. Thank you.

'executeOperation' is called by the Aave pool, atfer we call 'requestFlashLoan', after it performs some basic checks.

@@BlockExplorerMedia can you explain in more detail, like, can we call the "execute operation" manually?

thanks for the video. Quick question. What vscode extension do you use / settings for solidity highlighting. Thanks

@BlockExplorerMedia Жыл бұрын

I'm using the Solidity VC plugin by Juan Blanco which is great (using that specifically in this video). I have also used the Hardhat Solidity plugin. Prettier for formatting - you have to enable 'format on save' in VC settings and also ensure a formatter is set for Solidity.

ok correct me if I am wrong. You sent the contract 1500 USDC and 1500 DAI. That equaled to 3000. You then borrowed 1000 USDC. Where did the extra tokens go from the contract? You lost 2890 coins. It would of been cheaper to just perform the arbitrage yourself.

Makes no sense. Im also waiting for a response from the creator of this vid/contract
