Bug Patterns in Solidity and Smart Contract Auditing by Yannis Smaragdakis

In the past year, we (Dedaub) have disclosed numerous vulnerabilities in deployed smart contracts and received 10 significant bug bounties totaling over $3M. The talk derives from this experience: I'll talk about the Dedaub tooling (including the contract-library.com code explorer) and a couple of Solidity patterns that have been behind high-value vulnerabilities we've identified. The main body of the talk, however, will focus on a simple question: "what can I do as a developer to make my smart contract auditor more efficient and effective?" This is not much different from asking "how can I write better code?" but I intend to give actionable advice, based on numerous audits (and instances of hair pulling). In a way, this is an update of previous talks of the past 10 months or so. E.g., talks given at the Solidity Summit: https://summit.soliditylang.org/agenda (https://www.youtube.com/watch?v=hcRY0oMscoM) and at Chainlink SmartCon 2022: https://smartcon.chain.link/agenda The current proposal updates these talks with slightly different technical content: both because of new items, and because I'm keeping the elements that work best. (E.g., I had a talk at TrustX that turned out to be a bit "too technical". The above seem to be "just right".) Yannis Smaragdakis
