Thanks for this top content

[@Ts2pc]

Interesting, It is totally new for me. Thanks a lot!

[@pablog80]

Very interesting indeed. Now, a newbie question: I have studied quite a few contracts and I cannot figure where these operations may be needed. Any example, please?

8:32 think you meant to type 11 😬

[@smartcontractprogrammer]

Nice catch

[@vishalkulkarni3977]

thank you can you make video on banchor v2 protocol which reduces the impermanent loss

[@smartcontractprogrammer]

no, I heard they temporary stopped their impermanent loss protection

[@zacharysnyder3905]

Can you please give me an update on IERC20 please? I made a code that uses IERC20, but I put everything in correctly. I made the IERC20 code. And I have imported it in, and have used it in my code, but it is underlined red? I just don’t get why that is happening.

[@alex-dk2rj]

What’s the error

[@zacharysnyder3905]

@@alex-dk2rj It’s just underlining the IERC20 red. But, I don’t get what the error is. So, I am just going to put the things in the code to fix it.

[@alex-dk2rj]

@@zacharysnyder3905 should give you some error if you hover? did you implement all the methods and the function signatures match? Or is the error from sollint?

[@zacharysnyder3905]

@@alex-dk2rj I don’t think so, but I have just deleted the IERC20 code. Now, I have just turned it into events that have indexed variables in them. Here is a sharing for what I mean: contract ________ { event Deposit (address indexed sender, uint amount); event Submit (address indexed txId); event Approve (address indexed owner, uint indexed txId); event Revoke (address indexed owner, uint indexed txId); event Execute (uint indexed txId); } Do you see where I am going with this? I think it will just be less complicated for me, so I don’t have to do a lot more work.

[@alex-dk2rj]

@@zacharysnyder3905 not exactly sure what you’re trying to do but did you import the IERC20 interface properly?
