[@pan-galactic-gargleblaster]

I'm so glad this video came out! Couple weeks ago I took this aave mix for a spin on Matic. Long story short, the contracts deploy just great on mumbai and mainnet but brownie has a hell of a time interacting with contracts post deployment. Do you have any high-level intuitions why this might be? have you poked around on Matic using brownie yet?

[@PatrickAlphaC]

I sure have! Stuff worked fine for me... love matic (polygon). What were the issues you ran into?

[@pan-galactic-gargleblaster]

@@PatrickAlphaC you know what lol... I actually revisited that project just now. After getting my env variables up, I was able to call the contract and take out a flashloan using aave's lending pool on polygon. Didn't change an ounce of code; working inside of venv now, must have been the issue before. Anyway, for the adventurous in comments here: it is possible to use this exact brownie mix on matic. Just make sure to use the matic version of RPC, token addresses, etc.

@@PatrickAlphaC I've implemented the flash loan in matic, no prob, but now I'm trying to add in a swap on quickswap and I'm having a hell of a time getting the transaction to go through.

Hello Patrick, I really enjoy your vids, and I can use Python to develop some smart contract. I wonder could you make a video to introduce some methods or tactic about using smart contract to make some $? I believe so many tech geeks would be interested in, but we just don't where and how to start.

[@PatrickAlphaC]

Making $ should be derived from creating value in the world.In the videos here, I’m showing you the tools to create value in the world, and it’s up to you to put those tools together to create something of value. Look, I’m a fan of making money as much as anyone else, but if you focus on the making money, rather than creating value, you’re going to make a lot of things that don’t last very long, because their goal wasnt to actual give value to anyone, and are “gimmicky”. You can make a lot of money in the space following this. Seeking alpha to keep markets efficient is one way to create value. Finding alpha to help people keep their money secure is another way. Creating valuable art people like as NFTs is another way. Building insurance platforms where the insurer can’t f over the users due to trustless agreements is another. Focus on value, and if you build something people value, and then market it, the $ will come.

[@JohnnyDubstarCrypto]

Great video! I’d love to hear your thoughts on EQZ Equalizer. Dedicated to flash loans and LPs. Mainnet launch was yesterday. Now they need to fill up the vaults and create lots of liquidity over several assets. I would love to hear your opinion and maybe see a video if you have time! Thanks! DeFi and it’s new innovative tools are awesome!

[@PatrickAlphaC]

Haven’t worked with that yet, don’t know much about it, sorry!

[@aglamadrid19]

Thank you for the tutorial , I wanted to see it yesterday with the musk faucet up. Maybe we can use a flash loan to maximize rewards? My question is the payback, can we wait until another transaction happens before we payback the flash loan ?

[@PatrickAlphaC]

Nope. Gotta pay back in the same transaction. You can use a regular loan to do what you want.... but then you don’t get that leverage.

[@aglamadrid19]

@@PatrickAlphaC thank you

[@abc_12333]

If you want to profit with a later transaction, combine the flash loan with a collateralized loan. If there's a spread in 2 stable coins, you get the flash loan, put it in a Maker Dao (Oasis) vault and pay back the flash loan. When the stable coins go back to the 1:1 ratio you get another flash loan , get your money out of the vault and pay back the flash loan.

Should I put both in the same script or not? Thanks

Just curious why did you decide not to make it as a full time job, if that’s only factor to make this profitable if you already know how to code it? It seems that arbitrage opportunities will be always there from time to time, don’t they? Curious to hear what obstacles and difficulties you see.
