Signature Replay Attacks
Common vulnerabilities leading to signature replay attacks
Reminder to all PFPs (and others) creators: It's possible to allow gas-less trading on @OpenSea *very* easily by checking if current operator is the owner's proxy gist.github.com/dievardump/483… Allows to save the approval function #smartcontracttips
Don’t just audit, simulate attacks. Test your smart contracts like a hacker would. If you don’t break your app, someone else will. I'm talking to you Developers 👾 #Web3Security #BlockchainDev #SmartContractTips
✨ 𝗦𝗺𝗮𝗿𝘁 𝗖𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀 𝟭𝟬𝟭: 1️⃣ Automated execution ⚙️ 2️⃣ Trustless, transparent interactions 🛡️ 3️⃣ Powering Web3 innovation 🚀 Smart contracts = the building blocks of decentralization. #Web3Development #SmartContractTips
2/4 ⚠️ Reentrancy Attacks One of the most infamous vulnerabilities (e.g. The DAO hack). 🛡️ Fix: Use checks-effects-interactions pattern and ReentrancyGuard from OpenZeppelin. Always control your flow before calling external contracts. #SmartContractTips
Quick Tip: Using block.timestamp for critical timing? Remember, validators can manipulate it within a reasonable range. Always add buffer time for sensitive operations. #SmartContractTips
Solidity wizards, here's a trick for your toolbox: leverage modifiers to streamline smart contract logic! Enhance readability and security with elegant code structuring. 💻 #SolidityMagic #SmartContractTips 🚀
Protocols are only as secure as their weakest dependency. Audit everything, including third-party contracts. #SmartContractTips #web3security #solidity #blockchain #web3audit
Access control can make or break your smart contracts. Do you use OpenZeppelin’s libraries or build custom solutions? Let’s compare! #EthereumDev #SmartContractTips
What’s one security tip every new blockchain developer should know? A single line of advice can save a project from disaster. Share yours! #SmartContractTips #CryptoSecurity
8/ Mastering this = fewer bugs, lower gas, safer code. #SmartContractTips #Solidity #Web3Dev — ØxBasitVR
4/ 🧐 To check if a contract is sponsored, use the 'Read Contract' tab. If you get a Zero Address in return, it means the contract isn't sponsored yet. #SmartContractTips #ConfluxNetwork
4/ 🧩 Opcode Variations: The BLOCKHASH opcode in Conflux can only take NUMBER-1 as input, unlike Ethereum's range of NUMBER-256 to NUMBER-1. This affects how the Solidity blockhash function is used. #Solidity #SmartContractTips
#Solidity developers, remember to optimize storage usage to keep gas costs down. Efficient contracts = more affordable dApps. #EthereumDev #SmartContractTips
💾🧠 #SolidityBasics: Know the difference! 'Storage' is persistent on-chain, while 'Memory' is temporary. Don't mix them up! #SmartContractTips
#Solidity developers, take note! Avoid using var in your code—it may lead to unexpected behaviors. Stick with explicit types to keep your smart contracts secure! 🔐 #EthereumDev #SmartContractTips
Pro move: Integrate gaming mechanics like loot boxes into contracts. Fun + functional = future-proof. Try it in beta! #SmartContractTips #AIEdu @solana @CaptsQuartersTx Try this prompt & share results!
