Crypto Trading Execution with Flash Loans, Web3 and Hardhat (Udemy.com)

I really enjoyed the course. It was much more challenging then the Triangular arbitrage course, a bit more chaotic, but nonetheless very useful - I'm confident I can build something to test and execute my arb ideas. Some information in the course is outdated (there are new versions of ethers and hardhat for example) and you will need to figure out on your own how to fix it (thank god there's Copilot in VS code lol). But still a solid foundation is made once you understand the code that's presented by Shaun. Thank you!

I had another great experience going through this course! If you decide not to downgrade to the version of hardhat used during the course, you'll have to rely on some google/docs/LLM assistance for updated ethers 6.0 syntax , and some updates to hardhat (it now includes its own impersonate function and no longer uses waffle). I would highly recommend this course to anyone who wants to learn smart contract development!

Excelente curso, y complementa muy bien el de Arbitraje triangular, anteriormente no le daba mucho valor al mercado de cripto monedas, ni a la block chain, pero los cursos de McDonogh, me han hecho interesar mucho en estos temas, y a darles más valor, ahora pienso que la block chain, da muchas ventajas y oportunidades, a los que nos gusta la programación, me siento muy satisfecho por la información obtenida de este curso, y de el de arbitraje triangular que realice primero.

Good course. Wish it had more with UniswapV3. A little outdated (things move fast in crypto), but easily worked around. Good guidance. With any of these contracts, libraries, etc. some errors are just so cryptic they're hard to find and figure out. I kept running into "Unknown transaction error 3"... which I finally figured out was something going on with the node. Had to restart node, recompile the contract, and it would work like normal. After a bit, it would revert back to the error above. Wish there was a more comprehensive idea what a certain error message means and why you would get it. Overall, I recommend the course and would do other updated ones by this teacher.

Shaun is a genuinely great instructor who really seems to enjoy sharing his knowledge and benefiting his students more than anything else. This course provides an excellent overview of the solidity programming language, hardhat development environment, flash loans as well as other topics related to web3 and arbitrage trading. There is also a python and JS crash course included as well. Highly recommend this course to anyone who is interested in DeFi arbitrage trading.

I normally don't write reviews, usually I 5 star or 1 star it and no comment. So it's a high praise from me coming here to comment. This course, no....this instructor really is what made me do it. First and foremost you need to for sure have background skill in coding and blockchain. He explains everything in such great detail, such as why certain functions need to interact with others. This is truly complex to build and I grant you respect for being able to orchestrate this and at the same time teach it very well! One thing for sure, I spent a whole week trying to figure things out and fix problems and now everything works and what's more I have plenty of ideas to try ! Cheers my friend! I will be looking into more of your courses !

Lots of positives - it's really good to be taught the 'why' not just the how. Brilliant pace - it's not rushed, the concepts are expanded gently. All the mindset videos are fundamental to it being such a great course so far. Brilliant scope - so much info but it's all quite digestible and acceptable. The only criticism I have is that it's better to directly be instructed on what to do whilst the video is running- e.g. "just watch me code, don't follow along. When we get to the end - it's your turn". Really happy with this course!

You're going to run 10 functions at most in order to be successful at flash loaning, but it's a steep journey with unstable rocks under your feet. I took 3 other courses from this instructor. And this one has a whole another level of distraction due to the Solidity, Web 3, hardhat, etherscan, addresses etc... The flow of information gets constantly interrupted with some part of knowledge you have to acquire at that particular moment. I had very hard time to hold on, sometimes I couldn't stand it for 5 minutes at a time. I had to repeat and repeat... I'm at the final stage of the course and I still don't totally understand every part of it. I'm sort of annoyed.

Great course, packed with useful content. Really feel I have a much better handle on reading from the blockchain, doing swaps, knowing what the heck Uniswap and Pancakeswap are for. Teacher has very accessible, easy style, walks through many assumptions. Please keep making more content, we need more! E.g. more on liquidity pools and other financial engineering on chain would be great. Only thing to improve is really your screen resolution is bad (other people have mentioned this). If you could copy what leading teachers, e.g. Stephen Grider on Udemy do with regard to screen resolution, this would get a full 5 stars. Thanks sir, keep it going!

This course is great. Finally, I learned to use Flash Loans, after so many months of investigating, and run into intelligent contracts that were scams. You will learn not only to use Flash Loans, you will learn a lot about how to read and write data in the Ethereum and BSC blockchains, with JavaScript and with Python. In addition, you will learn Hardhat, a tool that personally I didn't knew, and I think is extremely important for the development of Smart Contracts.
