I have been studying Solidity for a couple of weeks and do not have any previous IT background. Are there any opportunities for me to get freelance work or earn money with my current skills?

I am new to Solidity! I wanted to say hello to this awesome community in hopes that it will get me out of my shell, and hopefully meet new people. I have zero programming experience, but love crypto. When posting questions in these forums is there a certain format I should post my question in, and/or any not so obvious rules I should follow in these forums? Thank you for taking the time to read, and leaving a reply!

Hi everyone, I've recently completed the Solidity and Foundry basic and advanced courses with Cyfrin Updraft. I'm contemplating my next steps and considering a career in Solidity. Should I start learning smart contract auditing at this stage, or would it be more beneficial to first create some projects to solidify my current knowledge? Looking forward to your advice!

Hello everyone , I've noticed that the offer function uses the .call{value: amount}("") method to send Ether to the recipient's address. Could anyone provide insight into whether this function is indeed vulnerable to reentrancy and suggest any best practices or modifications to mitigate such risks? function _offer(address to, uint256 amount) internal { balance -= amount; (bool success, ) = to.call{value: amount}(""); if (!success) { revert TransferFailed(address(0), address(this), to, amount); } } `

Hello guys, I have a question what if a user borrows $1000 from the lending pool and user does some stuff? Now what if a user transfers that money to another address and destroys his wallet? Because the user already transferred to another contract how would he get reverted with $1000 into the lending pool now?

Hi all, I have a query that can anyone explain main difference between DOS and MEV attack ? Because both leads to gas related issues. Transaction reverts in the both cases which leads to an error. So anyone clarify it ?

Hey everyone, I'm trying to deepen my understanding of certain conditions in smart contract development, and I have a question about a specific scenario. Let's say there's a "require" condition in a smart contract that must be met. If this condition fails, the contract needs to revert all changes made and refund any gas used in the transaction. My question is, how does the gas refund process work considering that gas is always consumed during computation? Additionally, I've heard about the "revert" condition but would appreciate some clarification on how it differs from "require" in smart contract development.

I know you can deploy contracts from Remix to Anvil. But is there a way to interact with contracts that were deployed from my machine in Anvil? These contracts are not visible in Remix. Or is there another tool like Remix that can do that? How are the experienced developers interacting with contracts? Thanks
