Today it was a funny day, I had been taking the Encode Club Advanced Solidity Course, and even though I already knew a good amount of topics from my work experience, I got to learn Yul. The weird thing is, you don't see it mentioned anywhere. I get a lot of job posts pushed to my feed looking for Senior Solidity Devs, but nowhere had it seen it mentioned. So what sepparates a senior from a junior? Well, I think it's knowing what that "assembly {}" bit does, and what exactly the solidity code is also doing under the hood once it's compiled. Now the best part, coming back to today, was to actually put it to use and lower the gas fee of a distribution function so now we pay less money for forwarding gas to our users. It was a small optimization, but seeing it pass all the tests finally brought that little joy of "task accomplished, I learned something after all those hours". And when you look back after all the things you've been learning, it certainly gives some degree of satisfaction.

New #web3 and #crypto job from Omni Network! Senior Solidity Engineer - Remote We’re building Omni: a platform allowing developers to deploy applications across all rollups without fragmenting liquidity. We’re looking for early team members to help us bring this ambitious vision to life. - Build a Solidity library and Typescript SDK for interacting with and building smart contracts with Omni - Design solidity contracts and token standards for developers to utilize in building cross-rollup smart contracts - Build a token bridge aggregator to give developers the best price execution on x-chain transfers, leveraging Omni’s messaging system for execution - Build developer tooling for prototyping and testing cross-rollup applications - Work directly with teams building smart contracts on Omni to give them feedback on protocol design, enhance their smart contracts, and loop product feedback from developers into our protocol and SDKs primarily Solidity, some Typescript and Golang Apply directly: https://lnkd.in/gW7wgg3M #web3jobs #cryptojobs #blockchainjobs

Solidity Deployments, tips and tricks 🛠  📣 From time to time I will share some deployer tips. Feel free to add yours in the comments below! • Use your main deployment script against your test suite, to ensure your smart contracts runs and pass tests with production configuration. • Deploy to fork environments for fast and instant deployment iterations with mainnet data, instead of waiting a testnet deployment (hardhat deploy --fork or forge script --fork-url) • Even if you use forks most of the time, deploy at least once in the target network testnet to check block gas limits and real gas usage of your app, before deploying to production. Foundry or Hardhat can not perform correct gas estimations in some L2 networks, and in some specific scenarios, you could exceed the block gas limits. Join to the Solidity Deployers Club to receive Deployment Tips every week! 📟 https://lnkd.in/eGy7v6W2 If you want to apply best chain ops practices, try out Catapulta.sh ✨ in your next Solidity deployment.

Pro-tip for Solidity developers In Remix you can do a search / replace, like in VS code. 1. Type ctrl-f, 2. click on the down caret icon, and you will see the replacement input 3. Fill the replacement value, press enter + command, it will replace all occurrences

SOlIDITY assert function in solidity helps in error handling

Solidity, passing functions as parameters 👀 Did you know that in Solidity, you have the ability to pass functions as parameters to other functions or even include them as elements in a struct? This is a cool feature which is not widely used. Here's a brief example demonstrating how to leverage this capability in a straightforward Voting contract. 👀 In this example, you have the option to create a specific function made for each proposal and then pass it as an argument. When a proposal is approved, the proposal.callback() can trigger automatically or manually, executing the pre-defined logic associated with that particular proposal.
