🧩 Day 269 of #360DaysOfCode Building Reusable Modifiers Refactored my contracts using reusable modifiers to make access control and validations cleaner. Makes the code more modular and easier to audit. #SolidityTips #CodeQuality #Web3 #SmartContracts

Coffee DApp shipped. README summary: From RPC fetches to payable txns. Gas calc? Base + tips = fair fuel. Portfolio piece #1 done. #Web3India #SolidityTips

Learning Solidity via @CyfrinUpdraft taught me one big truth. Writing failing tests first is the fastest way to understand smart contract logic. When the test passes, you don’t just fix code… you confirm understanding. #SolidityTips #BlockchainDev @CodeHawks @mahima_thacker

3. Enter delegatecall This low-level opcode runs code in another contract's context, using your own storage. It’s how proxies forward calls : (bool success, ) = impl.delegatecall(data); The magic behind upgrades. #SolidityTips #learningWeb3withMyke

✅ Voter must be registered ✅ One vote per wallet ✅ Candidate name gets a vote #BlockchainDev #SolidityTips

You control who can vote. 🗳️ – Voting Function Simple but secure vote casting: function vote(string memory candidate) external { require(voters[msg.sender], "Not registered"); votes[candidate]++; voters[msg.sender] = false; } #BlockchainDev #SolidityTips

[2/3] Use external instead of public for functions only called outside the contract. It’s cheaper because external skips copying data to memory. Small tweaks, big savings! 🤑 #Web3Dev #SolidityTips

02、Modifier 的使用 #SolidityTips

Incorrect modifier in Solidity. Modifier should always run the function code. Otherwise get function will return a default value. (most likely 0). #soliditytips

Pro Tip: Writing cleaner Solidity code? Use underscores ( _ ) to separate large numbers! ➡️ 10_000 becomes much easier to read than 10000. #SolidityTips #CodeClarity

PSA Let's add a bit of decorum to our Smart Contracts! Functions with `courtesy` modifier require sender to ask `please` before using... or they can `pretty_please` for a fee. - `stars` for priority use?? - what if `stars` were GasToken or Chi 😈 #SolidityTips

🚀 Solidity Tip: Use the keccak256 function to generate a SHA-3 hash in your smart contracts and compare string with it! 🤩 i.e: `bytes32 hash = keccak256("Hello, World!");` it will generate a fixed-size hash. 💻 #SolidityTips #BlockchainDevelopment

TIL: We can use named arguments instead of position based arguments when calling methods or instantiating structs. #SolidityTips #ReadableCode

🤔 In solidity, did you know... As of solidity 0.8.12, you can concatenate strings easily with string.concat instead of abi.encodePacked. #Solidity #SolidityTips #Web3

#soliditytips Using the selfdestruct function, you can send Ether to a contract that does not accept Ether. This function will transfer all Ether from a contract to an address specified by the caller.

Decimals in Solidity can be tricky. ERC20 tokens like ETH have 10e18 decimals, but not all are the same. Precision matters in price conversions – adjust decimals first, then divide. - below example shows conversion of price to USD #SolidityTips #Solidity #Chainlink

Smart contracts can transfer ether to address via three methods which are transfer, send and call. For an address to be able to receive ether it must be declared as payable. When ether is sent via transfer and send method, 2300 gas is sent along for execution #soliditytips

#soliditytips Error in Solidity can be thrown using either one of require, revert and assert. As at Solidity ^0.8.0, there exists an error type that can be defined by you. Require is used to test for a condition and if the check fails, an error is thrown

Did you know that if you view any verified contract on @Etherscan you just need to change the domain to remix.ethereum.org and it'll open it up in @EthereumRemix #SolidityTips #SolidityHacks #SolidityRemix
