Executing whitehacks is hard also for security professionals 🤖 But there are three important rules: - test and don't change before execution - execute in a single tx - execute privately ( reorg 🤞) Here a starter foundry repo 🫡 github.com/emilianobonass…

CREATE2 opcode usage potential issues/attack vectors: - deployment griefing by front-running with same `salt` param - selfdestruct opcode leads to a "metamorphic" contract - not checking if the returned value is not the zero address (failed deployment) What else?

if you inspect a transaction which calls an unverified contract, you'll get a best-effort recovery of the original function parameters. works as long as the contract uses the standard abi. no more hand-deciphering calldata!

These two ways of transferring ETH below are functionally identical - but there can be surprising difference in gas usage. In fact the call() version can pay approximately three times more in extra gas per 32 bytes of data returned! 1/5

Why an immutability in a blockchain system is a double-edged sword?🗡️ Shouldn't the smart contracts stay as they are? But what if there is a bug?🐛 In the following 🧵I will explain the following • Why we need upgradability? • What are the proxies? • What is a DELEGATECALL?
