Off The Chain ’s Post

Deployed a Contract on Testnet(Sepoliaeth). Thanks to Patrick Collins Things I've learnt in this course of study are; > Functions > Mapping > Basic Types (Bool, Int, address, bytes) > Storage and Visibility, etc Still moving forward in Solidity 101😉

Minimum full-time Smart Contract Developer salary at Uniswap Labs: $290,000 - $325,000 USD. 👍 But do you know how to code a DEX? :) Learn how in one of my Contract Audit Livestreams this week! Monday, August 5, at 9:30am Pacific Standard Time -> https://lnkd.in/gDFUaXwV Tuesday, August 6, at 1:00pm Pacific Standard Time -> https://lnkd.in/gXy5umT9 Wednesday, August 7, 11:00am Pacific Standard Time -> https://lnkd.in/gP--FHmJ Thursday, August 8, 1:00pm Pacific Standard Time -> https://lnkd.in/gVBrTjdX If you have no clue what an Automated Market Maker is, don't worry. It's just some rules and formulas that get encoded into Smart Contracts. Ya gotta see how this works! Because the future is decentralized.

Announcing Gas Abstraction for Web3 Developers! 💻 ⚙ Gas Abstraction enables devs and companies to build smart contracts in blockchains without worrying about tokens, ETH or native gas. No need for ETH or native coins, means no more crypto volatility in company balance sheets! 📉 📈 Prepay in credits with EUR/USD or stablecoins and be able to deploy smart contracts anywhere. This lowers the barrier of entry for Web2 developers and makes Web3 development very easy: focus on code, not on infra. Catapulta analyzes your deployment, funds your deployer and bundles all txs to the desired chain, all while not requiring code changes, 100% vendor free and compatible with the best open source frameworks like Foundry. Gas Abstraction beta is available today at Catapulta, and we give away $10 to deploy in any of the followings testnets: Polygon Amoy, Ethereum Sepolia, Ethereum Holesky, Avalanche Fuji. DM us if you want a demo and gas-less operations!

Solidity Challenge #366 🕵️♂️ Below is an example of how you could create a smart contract with a function to check the validity of a Merkle hash. This example assumes that the Merkle tree is binary (each node has at most two children) 👯 What are the flaws in the contract?

Sentiment around ETH is awful, and I see little to no reason why it should improve in a big way anytime soon. Could alternatively be L2 solutions (as long as it is not a useless Optimism fork) People talk nice things about Base and they seem to attract the best devs in bulk, judging by contract deployment. Base (651k) Blast(2.4k) Arbitrum (38.4k) Immutable (15.2k) Manta a bit worse (1k) ZK Sync extremely long shot (21.5k) (Total contract deployments in July’s last week. For the entire July check the comments) I arranged the above based on my subjective feeling of how many people talk nice things on X. Base is undebatable #1 the rest is more of a free style. Cast your L2 vote below 👇

#web3 #web3pentesting #smartcontracts #bugbounty DAY-16 Visibility In Solidity, functions and variables can have one of these four visibility specifiers: 🌎 public: accessible from both inside the contract and from external contracts 🏠 private: accessible only within the current contract. It does not hide a value but only restricts its access. 🌲 external: used only for functions. Visible only from outside the contract. 🏠🏠 internal: accessible by the current contract and any contracts derived from it.

Advanced Solidity Insight 🛠️ Building Reliable Smart Contracts: Insights from a Solidity Developer One of the keys to writing efficient and secure contracts is understanding gas optimization. For instance, did you know that choosing memory instead of storage for temporary variables can significantly cut costs? In complex contracts, every bit saved counts. Another best practice is using require statements early to validate inputs—this prevents unnecessary computations and reduces gas costs. After years of building smart contracts, I’ve seen how even small optimizations make a huge difference in Web3 applications. If you’re also a Solidity developer or interested in the details of contract design, let’s connect! #Solidity #SmartContracts #BlockchainDev #GasOptimization #Web3

Depending on tokens for liquidity is the major problem of projects in web3. Many of these projects lack real utility that can fetch provide liquidity apart from token sale.
